PostPosted: 18:45 - 25 Aug 2009    Post subject: Psychological New Tyre Issues. Reply with quote

I have recently put a new rear tyre on the bike. And just found out that my new tyre is aimed primarily for 'touring' rathing that being a 'sports' tyre.

When I was looking at buying tyres, the 3 different garages I tried all told me that I couldn't get the BT-56 anymore and that the BT-020 was the replacement for that tyre since it had been discontinued - so I assumed it would be basically the same grip, etc.

But I have checked the Bridgestone website and it looks like the tyre is meant for loads of mileage, and NOT being thrown into corners.



Since reading this information I have been a bit scared of leaning right over on the bike just in case it slips out from underneath me. The tyre is fully scrubbed in now so there should be no problems with this, but the fear is still there....

Anyone else had any problems like this ??? Or is it just me ? Is the problem all in my head ?

Will the tyre be OK for getting the knee down on roadabouts, etc or should I try and stay upright like a proper touring bike ? Here is the information if anyone fancies a wee read:

Just scrub it in and crack on you'll be fine.

Usually, (i think) touring tyres have a harder wearing compund in the centre of the tyre but still have grippy edges for hustling through the twisties. I had bt-o21 on my old cbr and the stuck like shit to a blanket when i cranked it over.

The 020 is fine for knee down etc. Now, I did actually crash with an 020 on the back getting my knee down on a roundabout.
However, I was going quicker than a rider with two sports tyres and after I realised the tyre was giving masses of signs that it was going to let go. Glad it happened as I now know exactly what to look out for.

Don't be silly and you'll be fine. Just means you can't get on the power quite as early, or brake quite as deep into the corner (not that I'd be doing the latter on the road anyway.)

i second what G's said, the 020 while being a harder compound is still a very good tyre. I used them on a VFR750, topbox and all and would easily roundabout surf with them on. Though i have to say, i do prefer 014's etc. even to tour on because, like yourself, personally at the back of my mind i like to know ive got something up to the job!

i recently crashed quite epically on track because i had shit tyres and pushed too hard...wont be going down that road (or track hehe) again i can tell you.

that said, winters on its way and both stickys and tourers alike arnt so great so i would get used to them and muddle through, the extra miles will be great in winter!

I've got 020s on my CBR, more than enough grip for the road, no chicken strips on my tyres Laughing Maybe a bit poor in the wet however.

I thought the 020 had just been replaced?

the 020 has been superceded by the 021 (which I have on a fazer). You can still get hold of the 020 if you search for them.

I had a Continental SportCity or something on the back of the RS50 before I changed it, was as hard as rock but you could still knee-down on it.

Got Sport Demons or w/e on the 125, feel much more solid than that ever did. Thumbs Up

I don't think anyone needs much better than an 020 for the road.

The tyre is better than you are, unless you are Valentino Rossi. Karma

Aye modern touring tyres are excellent. I've had BT020, Avon Azaros, Dunlop D220s, D207s, Contiforce, Macadam 90s and Pirelli Dragon GTs. And thats just the radials, not getting into crossplies.

All worked fine, even at a spirited canter.

I mostly ride older high powered 4's (GSXR1100s, FJ12, FZRs etc) and the sports touring and touring tyres these days are better than the sports tyres that they would have originally come with.

I don't think anyone needs more than a pair of bark and twine flip flops for the road. Wink

Oh and Rossi could no doubt ride amazingly on a set of cheap Chinese tyres, finding and staying right at their limits.

For the rest of us, it can be nice to have a bit more grip, so that when we mess up, the tyre makes up for it.

The difference between an 020 and an 016 on the road is purely psychological.

You cant get them to warm up in normal use and they if anything grip worse than the touring tyres in the wet or pootling around.

I ditched a set of pirelli diablos for the Dragons for that reason.

I disagree. I've been in situations where an 020 has started to slide and in a very similar situation an 010 hasn't.

I've found 010s had way better grip in the wet than 020s, thanks to having a stickier compound in the first place.

G, as I have said before, not many of us here have the same kind of feel for a bike that you do.

I'd be happy with a BT020 on my bike, and I'm sure you would be too. What I'm saying is that the guy doesn't need to be concerned that he is now automatically going to crash because he has a different tyre. As Sickpup said recently, it doesn't matter what tyres you have on the road as long as they are modern and not trail tyres pretty much.

G, this is the same as you saying that everyone should have a 1000cc four cylinder bike. Perhaps that is relevant to YOU but it is not relevant to 90% of riders.

020's are fine for 90% of riders, certainly on the road.

But, as I've said many times, I really don't ride that fast on the open road compared to many and... having good feel* however would be good for riding on less good tyres if anything.
It would make more sense for those with less 'feel' of what a bike's doing to have better tyres, especially as in my experience the sportier tyres tend to lose grip more progressively.
You're suggesting that people who find it harder to tell what a bike's going to do have tyres that don't grip as well and tend to let go quicker with less warning Confused.

I went from an old 010 to a new 020 on the rear of my stock ZX6 and wasn't happy with it. I was able to ride ok with it and the only crash was the one I mentioned above. However it let go in some instances which the 010 didn't. These were mostly in a straight line accelerating in the cold/damp/with cold tyres - so nothing to do with me trying to do silly manoeuvres, purely a case of a less grippy tyre.

As I've said before. That's fine if you're a perfect rider that never makes mistakes and doesn't try and push themselves or the bike ever. If you do make mistakes, it's nice to have a safety net of extra grip.

Quote:

Actually, I have never said that at all. And, as I said the other day, it is not right for me; I wouldn't choose one for fun, though I find it's ok for commuting through town.
Infact, you'll find the times when I have suggested a big litre bike is when people are saying they want a bike that's easy to go fast on, or, more often, when they are saying they want a 'torquey' bike. I also often suggest/joke people get a modern litre bike and restrict some part, as they tend to offer pretty much everything possible.
If I told everyone to get the bike I wanted, I'd be telling everyone to get a KTM144SX, which I don't think I've ever suggested to anyone (well, maybe once or twice.)

I offer advice based on how I believe the item in question will react in the situation in question based on my analysis of having tried many different things - thus possibly your mis-assumption that I would choose a modern litre bike, were I to have the choice.

Finally, would you have crashed your blade had you had a decent set of Supercorsas on? As it sounded fairly marginal rather than a full on wide-open-throttle moment, I doubt it.

Bark and twine flip flops are fine for 90% of people to use as their main form of transport. People generally choose transportation that lets them have more fun however Wink.

* Which to be honest I don't think I have, not compared to some I've raced with. Infact, I'd say you tend to describe getting a lot more feedback from bikes than I get.

This is the rear 021 (touring tyre) on my ER-6f work bike. This bike is only used for work often in the most atrocious conditions you can think of.

As you can see, little chicken strips and a lot of chain lube.

Trust me there's enough grip on them.

OK, let me put it another way:

This guy is asking for reassurance that his tyre is not a chinese piece of plastic, and that it will actually provide some grip. It is a modern Bridgestone designed for sporty riding.

My Powervalve has a general reputation for having poor tyre choice. I fully expected that as soon as I rode the bike I'd be scared by the lack of feedback and grip that I would get from the best yet clearly awful choice of BT45s. In actual fact I needn't have worried as they are perfectly fine for the type of riding that I do, or can do on the 'valve.

You say that you felt that the 020 broke grip when opening the throttle hard in damp and wet conditions. Most people (including me) tend to avoid opening the throttle hard in damp conditions. The fact that YOU noticed a supposed deficiency in the tyre is kind of irrelevant because the OP might not notice the same deficiency.

Modern tyres are good. They are good enough to my mind that pretty much all tyre problems are either down to a lack of 'feel' (possibly caused by poor suspension setup, rarely a genuine tyre issue) or more often than not a psychological barrier rather than a genuine one.

I'd estimate that 60-80% of tyre issues are psychological.

Interesting thing here is that if you asked which tyre suited these conditions best Bridgestone would say the 020/021 touring tyre as it would be at the correct temp. The Supersports tyres would be no where near temp and consequently wouldn't be 'sticky'.

Probably higher to be honest.

I needed some bald front tyres for bikes in storage so went down to a mates tyre shop last week, he said grab two off of the used pile. One was an MEZ4 with 4mm of tread and the other iirc was a D204 with 2.5mm of tread, changed because the owners thought they weren't good enough.
The 020 I've just fitted to the front of my ER-6f is about 6 years old, works fine.

Which was exactly what my first post gave him, though I didn't claim it was designed for sporty riding, because it wasn't, it was designed for longer distance riding Wink.

As said before, I've used BT45s - they're not great and I would certainly tone down my riding slightly to compensate, however thanks to that haven't crashed (much, anyway) while using them.

I know plenty of people that will accelerate hard in the damp. Most people don't ride bikes, but in my experience a good proportion of those that do, the more serious 'bikers' at least ( Wink ) still ride their bikes and have a bit of fun even when the weather isn't 100% perfect.
However, partly, the point is that this points to the fact these tyres are not as good generally.
A car pulls out in front of you in the same damp conditions - you can probably brake harder on the 010 than the 020. Regardless, I think more grip is useful there and it's useful to know how much you can push your tyres. I will often wheelie and (at low speeds) brake test tyres to see how much grip they do have in adverse conditions so I've got a good idea should bad things happen - it also lets me adjust my general riding accordingly.

Plenty of modern tyres are far from good to my mind; I value tyres that grip well from cold, as I often am either stopping regularly or not riding fast enough to get a tyre up to temperature. There's still a decent number of modern tyres that don't grip well from cold.
As I said, I bet quite a lot of crashes do happen which could be avoided with better tyres in the absence of better skill - I know quite a few of mine could have been. Don't think you can claim broken fairings are just psychological.

Sickpup - I have tested the 010 and the 020 back to back. A worn 010 had better grip from cold than a just scrubbed 020. Just as I find supercorsas have better grip from cold than many other tyres that are actually designed for road use (in contrast, Pilot Race's have absolutely terrible grip from cold and I wouldn't have them near a road bike myself.)
I was riding fairly uneventfully with a ten year old diablo or something on the back of the zx9. Mostly I just had occasional little slides with no real 'danger'; however that was because I rode accordingly. With a supercorsa on the rear now, I can ride a lot more aggressively and so far have only had one slide, which was on a questionable bit of tarmac anyway.

Just to reiterate and expand on my first post for the thread starters benefit...

When I bought my CBR it had 020s on it. I know feck all about bike tyres but need to replace the rear soon so was looking at them. Basically, I was VERY surprised to read that the tyres I had were "touring" tyres, I'd just assumed they were super sticky sports jobbies as the bike feels great on them and was pleased to discover I can get similar replacements which will last a long time and be grippy. I have no end of confidence in them and had ZERO chicken strips within a couple of weeks of getting the bike (original owner must have been rubbish Laughing ) so they can take a decent lean angle.

Yet Bridgestone disagree with you.
The question is did tyre perform better or did you just believe it did?
Impossible question to answer really.
Must admit it's pointless asking me, I never have problems with tyre choice.

Well, I'd say with the riding the average biker in commute or ride or quick blast does; unless you're leaning into a corner on squared off jobbies then you'll be fine and well.

Sounds like they're fine for you then Tommy.
Just a note that given the right situations, even the very worst tyres it's possible to get rid of the chicken strips on generally.
The telling thing is when a deer runs out into the road while you're in the middle of getting rid of the chicken strips - that's when you really work out how good a tyre is Smile.

Quote:

Big corporations have one aim generally. To make as much money as possible.
Some veer towards doing that with truthfullness, others will do it by any means, or will make up a lot of sciency stuff in the hope people will buy their products on that basis (actually, in my experience most companies selling a product or service that costs a bit tend to do this regardless Smile ).
Do you have a reference listing that the 020 has better grip from cold than the 010?

I am very confident the 010 did perform better. For a start, the first few times the 020 let go I wasn't expecting it - we're not talking a placebo style affect here. Later from that, I made a point of testing it in situations I had put the 010 in. I have done similar with an old D204, 010 and supercorsa as well. The 010 and supercorsa performed fairly consistently well from cold, the old D204 was absolutely terrible. (In this case, mostly testing wheelies on the same patch of road in similar conditions, with a few brake tests thrown in.)
Similarly, the first time I crashed on the Maxxis I put it down to my own stupidity. The second time with that ruled out, I realised that it was in fact just a tyre that performed very poorly from cold.

Ive found that its not sliding, the harder tyres can feel "squirmier" but dont let go.
