Overheating tyres pos???

Went for a spin today, and had a little slippsie (not an off).

On the side of the tyre in question, it looked glazed, and was "tacky" to the touch.

Does this mean the tyre was overheating or something? It wasn't even a hot day. Confused

I thought it bubbled up when they overheated.

Don't want it doing that again. Thanks.

Could the patch in question not be an effect rather than a cause of the slide?

It wasn't a patch, this texture was all the way round both tyres. It did kinda feel as if it wouldn't be as "grippy" somehow.

Hi

Very much doubt you would get anywhere near overheating a tyre seriously on the road.

My guess would be that you have ridden through something, or something from the bike. Chain lube (quite tacky), tyre slime, something like that.

All the best

Hmmm it felt like the tyre was "melting". Not as if something had become stuck to it.

Maybe it's because they are sports/commuter tyres. Not sure. I am sure I've had the same texture on the front end and it's let go momentarily a few times.

O well. Summer's just about over now anyway, hehe.

you can heat up a tire too much, if your suspension isnt good and you are pushing it, on small bikes this is easy to do as the suspension is usually crap anyway, and with light weight and easy flickability, you dont notice a small bikes suspension shortcomings, but you are hardly likely to do this on the road.

the real damage gets done if you allow them to get very hot, then cool down again quickly and dont put heat into them for some time, then ride them hard again. do this and you will soon find them hardening up, and you will notice a blue/green/red sheen on the surface, near the edges. i think this is caused by the oils leching out of the rubber. i sometimes see it on my road bikes if ive been out for a last blast at the end of the summer, then take them out of the garage in the following spring.

you will see lots of part worn trackday tires for sale, with loads of tread, and probably the sheen on the edge. i wouldnt touch them - the people selling them know they have 'gone off' and selling to buy a new set of the same with much more grip.

OK thanks, I'll keep an eye on it.

Can't have overheated, as in France we were pusing it harder, and it was far far hotter. Wierd though.

Thanks again, Claud. Thumbs Up

my dads tyres seem to get glazed and tacky when left in the garage for a week or so.

might it be moisture in the air affecting the tyre compound?

If the chicken strips have a bit of blueness around where they meet the grippy part, then they'll have been overheated.

I've had BT010's and all kinds of Dunlops have blue rings around the edges when they've been left a few days without use, thought it was fairly normal.

my dunlops (sportmax) also had blueness when left for a couple of days. so may be normal. having said that, i always said they grip as much as a colouring crayon.

I've been riding for 28 years, I've only once had a tyre 'go off' it was on the front of my FZR1000 and blistered.
Usually if you pay decent money for decent tyres you won't have a problem, yes, they will heat and get very sticky feeling, thats how they work, if they didn't you'd fall off, hence the reason racing bikes and cars do a 'warm up' lap, its to get the tyres up to working temperature, why do you think they use tyre warmers?
Some tyres suit some bikes more than others, my Ace was crap with Bridgestones, used to slide on corners but with Metzlers or Dunlops it would stick like glue and give me no worries.
If you ride erratically, accelerating and braking a lot then you will heat the tyres more, creating a loose surface of melting rubber, you sometimes get a slide from this, this is what they mean when they say the tyres 'going off', if you cool it and run it sensibly for a short time it will wear of the loose stuff and return to normal.
