Track - Tyre Wear

Deck chairs could do with an update maybe...

Just pulling your leg mate. I'm interested to hear the 'track guru' responses too.

 

@Sam1199S is good with this stuff. To me that is not terrible but you are getting what looks like a little cold tear from having too high pressure (or possibly spring rate or rebound settings).

 

Ah yes fairly likely pressure related then. These ones warm up quicker as they are road tyres but 30 cold is certainly too high for Supercorsas. You look fast in your vid (nice vid by the way ) so might actually be that they are over heating. I had a similar thing happen with the Supercorsa SP at Spa because I forgot to let the pressures down before going on track.

 

do you use tyre warmers mate??

 

Tyres looks pretty good, you want it looking like small ripples on a beach and yours does

30 rear cold sounds a bit high for track, assuming no warmers? I'd probably start 31 front and 28 rear on a road tyre like that. Front should get up a couple psi and rear end up around 30 ish hot...not too much more.

 

Btw no way a tyre guru but have raced on similar tyres with no warmers. On mine I would run 26 rear cold...but then I do create a bit of rear end friction and wear tyres out







Cue Vaz-eline smut...

 

I found this link, originally posted here some time ago, very helpful. Race Track Motorcycle Tyre Wear Guide - Types and Causes Andy

 

You're better off setting your pressures as soon as you come in from the track, so you can get a better gauge of heat in use rather than guesstimating with a cold tyre. Even off the warmers, my rear can gain 1-2psi when I come straight in
That wear looks pretty decent to be honest
I'm not sure on the SP chart, but an SC compound Supercorsa should be in the range of 26-29psi hot

 

I started using tyre warmers mate and don't get any tears any more think it's to do with the heat cycle that buggers um up.

 

I use d211's and warmers they seen to last much longer.

 

road tyres aren't too bad for heat cycles but its better to use warmers if you can

does add quite a lot of faff tho

 

Warmers are well worth having. The SP version of the Supercorsa is less prone to issues caused by heat cycles, as it's effectively a road tyre with a track intention and warms up well in normal use. Whereas the SC0/1/2 versions are are track tyres that you could just about scrape using on the road on a warm and dry day, and a few heat cycles will see them losing grip very quickly
Tyre warmers mean you're only putting one heat cycle in per track day, whereas no warmers would put 6 or 7 cycles in and could well mean they're past their best

 

If you didn't want to buy some, most TDO's will rent you a pair for the day for about £20
