i guess its the evolution of racing for this to happen. the tires are getting better bu ti dont think they will ever be as good as foam.
for spec classes i think the spec tires on black carpet last a very long time if you dont true them to one run spec, and unlike rubber tires, they dont drop off after x number of runs. as long as their is foam on the rim they are good. for club racing you could start larger, 42/43 and get a few days of racing on them, takin them off to save when they get really small for the main or what not.

I do wish the tires were significantly less expensive though. $17cdn for a pair of crc tires is a little silly when im going to walk over to the truer and take off like 80% of it. sell the tires pretrued for less money... its a waste thing for me...

if gtr tire price is any indictation im not sure how i feel about it. if they can sell a full set of tires close to what touring car tires cost, then id be onboard. as with touring car tires, i wouldnt expect the tires to be GOOD for more than weekend of racing. sure they will last and be usable, but if your competition level is high, it will just add cost i think.

it wont stop me from enjoying club racing, but for bigger races id stay away and just run modified i think. then again, with most touring car races pushing a spec tire it might be fun to show up and you get one set of tires for the pancar as well. for $25-$30 this is reasonable, but arent gtr tires close to $70?
