Ok then whats the deal with warmed up tyres ?

[Rob636]

ok then, i got myself thinking yesterday, cause after my 20 mile run in the sun last night at averaging 135 mph on the way back from work, i got off the bike and felt the tyre and yes its really really hot, but when you rub the tyre, it actually doesnt feel anymore tackier then when its cold, or atleast im not noticing a big difference, so whats the deal, is this something standard road tyres are like ? i have michelin pilot powers dual compounds there meant to have softer edges, but im not really feeling much differences,

would it be if i bought say pirelli dragon evo corsas, they would warm up and go tacky, is it cause there road tyres ?, i only ask this because although i aint got my knee sliders on, im almost brushing the tarmac in my leather ( yeah i know knee slider pucks gonna be on order ),

ok then thats my ranting over

so if i had softer compound tyres would they show more tackiness when warm, or is it the small difference when warm that is making all the difference ?,

and before anyone asks, yes i too wait a fair few miles before laying the power on down !!!!! cheers guys

Right, heat in the tyres doesn't actually make them any stickier, it makes the more maluable, this allows the rubber to squish in to gaps in the tarmac which is what gives you grip.

To put it another way if you imagine a ball of plastasine, if you put it in the fridge for a while and got it nice and cold, then took it out and tried to squidge it in your had it would be quite hard, however if you play with it for a bit it will become softer, when you squidge it in your hand it will push out beween your fingers, this is basically how tyres work.

I hope that makes sense if not sorry.
