There was a lot of discussion on the rule proposals for 2016 and in the end the language seemed to stay the same (copied below). Before I replace whats left of the tires that I wore ragged at CVR, I wanted to be certain on what seems to be a lot of leeway...
Using stock rims on a car with front and rear widths of 235 and 265, replacements of up to 255 and 285 would be acceptable?
Modifications not allowed for Street Stock...
o) Installation of factory or aftermarket front wheels with a width
greater than the widest front wheels available from the factory for
AX, DE & TT Page 11
that model range, and rear wheels with a width greater than the
widest rear wheels available from the factory for that model
range; any increase in track (front or rear) greater than 14mm
over stock.
p) Installation of tires with a section width more than 20mm wider
than the largest tire available from the factory for that model
range.
Thanks,
Shawn
