| Heat cycles come into it as well though Jools, especially with tyres that are used for racing. Also the profile of the tyre is much more important on a bike than it is with a car tyre.
I read somewhere that the tread design (on bike tyres) is only for asthetics and does very little to aid wet or damp grip, (i think it was an interveiw with someone from Dunlop). Most modern bike tyres are not very good in the wet because the design trys to get as much rubber on the road as possible so fewer grooves. Its the heat and rubber compound used that gets the wet grip
I'm not trying to get a few more road miles out of my set, i just dont want to chuck them away if i can still use them on the (dry) track. I'll get a new set for the road and then swap them for the track or leave them on if its wet or damp.
Good discussion guys! |
