New Tyres

Terry Johns:
The new 2015 SCCA tire regulations for stock classes sound absolutely absurd, 200 ware rate, that makes by brand new bone stock MX5 illegal in stock, go figure  >:(

MurrayPeterson:
The OEM tires are Potenza RE050A?  IMO, you are fine to run them at club events (not regionals or Nationals).  Tire manufacturers aren't allowed to mark a tire with a higher tread wear rating than measured, but they are free to go as low as they want.  The Potenza are one of those tires with a tread wear rating that is very low for marketing reasons.

Stuart:
ASN Canada has extended the 140 treadwear rule for the 2015 season (Toyo, who is the national sponsor needed more time to fully roll out their rebranded tires)  One thing you will find is that the new generation of 200 treadwear tires will stick far better than the RE050A's (Dunlop Direzza II Star Spec, Bridgestone RE-71R, BFGoodrich Rival)

MurrayPeterson:
Thanks Stuart -- I had forgotten about the ASN Canada extension.  Which means the tires are legal for regionals and Nationals as well.

Terry Johns:
 :) :) :) :) 8) so my 140 ware isn't going to be an issue at the nationals?
