I know this gets talked about loads, But unfortunately for me I only have a choice of 4 tyres for my ninja as they are 16" wheels.

The choices are

Pirelli SPORT DEMON
Bridgestone BT45
Metzler LAsertech
Avon RoadRider

I may decide to turn into an old bike for trackdays once ive got the diversion running so I would like something good for them and in the wet. I dont do a lot of miles so as long as get 3k from the tyres they should last me a few years, or until I sell the bike.

Anyone used any of the above. Don't mention anything else (Unless comes in 16")

Cheers

BT45's...

I have these on my r125cc and they are fantastic in the rain and dry.

I had BT45s on my last bike. Good grip, good price and good life.

I have Avon RoadRiders currently. They are so lolworthy. If it's slightly damp outside my XJ600 will spin up the rear wheel accelerating from 30. That's saying something.

Ive got some avon tyre on there at the moment. there are from about 2005 so quite old, but like new tread wise. but they skip real bad and I dont get any confidence cornering. Also MOT is due soon and advisory from last year was that the rear was out of shape slightly.

Avon Roadriders are terrible IME. No confidence, little grip, take an absolute age to warm up. Horrible.

I read a great special project Fast Bikes did last year on tyres. They took some bikes to Dunlop's test track in Spain and knocked fuck out all the big names data recorders onboard et al. They admit they were not 'selling tyres' but just cutting through the shite we read from all and Sundried about this tyre and that tyre.

You can download it from Fast Bikes website I think.

How do things stand with regard to mixing tyres?

The rear on my CB is on its' last legs. I've been told BT45's are top notch, but apparently you need to inflate them more than stock.

That would mean a rear tyre on 38-40psi and a front on 30 (because it's a Pirelli).

Would that cause problems, or is the point that the higher pressure simply results in the same performance anyway?

On a new tyre you may feel the front end behaves differently on mixed brands. The tyre construction is the important thing. They way the belting is laid down as well as the compound.

Possible not as noticeable on worn in tyres.

I never mix and any bike I've bought always gets any shit rubber replaced with recommended stuff.

'I feel' the OEM probably tests tyres a lot more accurately than most folk do (or can afford to) since Mr. I've Gotabike probably only changes tyres once every two years and his/her 'experience' is not very scientific but more probably based on simple anecdotal and how they are feeling that day as opposed to how the rubber peforms. That leans towards my thinking that anything the OEM says fits is the tyre to use.

Loads of folk disagree but who the fcuk are they??

Mmm.

I'm not really concerned with 'grip' at all (past the basic stuff like does the tyre have tread, is the rubber old). The sort of riding I do means that the only way grip would become an issue is if I hit an ice sheet or an oil slick, in which case I'm not sure there'd be a whole lot of difference between tyres anyway.

I was leaning towards the BT45's because I've heard they have longer life. Then again, I've done 7k on my rear (and who knows how many miles before I bought the bike), so perhaps it's not worth worrying too much. An £80 tyre makes that 1.1p a mile.

I had a brand new BT45 on my rear wheel when I got it, ran it at 36 psi as recommended and it was squared off and replaced at just over 7,000 miles.

I fitted another and ran it at 38 psi (whether taking a pillion or not). The new one copped for a nail the other day at about 6,000 miles and has been changed, but was doing much better having maybe 3mm of tread left down the centre and only very slightly starting to square off. It's true, an extra pound or two depending on your weight seems to make them last longer.

I can heartily recommend them for grip too, certainly for a CB500 anyway - I rode all through this winter (used public transport twice to get to work when it was stupidly icy) and never lost grip once.

Mmm.

Well, the Sport Demons I have on back and front are doing well. That's what I got 7k out of. But the rear has been squared off for a long time (3000 miles +). I just stuck with it because it seems a waste of half a tyre, I hardly lean anyway. Tread was fine.

I must have had a different batch of Avon RoadRiders, I found them to be superb in the wet and cold, and more than adequate in the warm and le dry.

These are BT45s (Foreground)
https://i104.photobucket.com/albums/m174/howlingterror_2006/IMG_0085-1.jpg

They do show a strange wear pattern. A lip appears on the diamond shaped tread. Not noticed a difference in grip level but it does track the road surface, when new they didn't.

I found they wear too quickly.
I still rate them.

Roadriders are great if you prefer to change your tyres once every decade.

BT45s ftw.
