Fellow CMC-ers
We, your series directors, have argued long and hard about what we are seeing after running some of the new for this year tire configurations and feel we need to make some immediate changes, as well as announce some changes to come in for 2009.

First, the immediate changes:
Effective immediately, maximum tire size for CMC2 cars is 275/40R17. No changes to CMC allowable tires. Further, wheel manufacturing/assembling method is no longer restricted, but your wheels must still weigh 16lbs or more. I’ve detailed the changes in the tech bulletin.

Changes coming for 2009 that you want to know about now:
For 2009 the Toyo R888 and the Toyo RA1 will both be allowed in the respective maximum sizes for CMC and CMC2 cars. Toyo intends to continue making the 255/50R16, and we therefore intend on continuing to use it for CMC.

Since you’re going to ask…the driver for allowing the fatter tire in CMC2 cars centers around several things, in no particular order, which include compatibility with other series, availability of wheels, a sidewall that is less prone to wrecking wheels, and less dramatic change to required car setup.
