What is the widest ET street tire that I can have in this class. I know the rules are limited to 10.6-inches but i just want to know if i can run my 30X13.50 ET streets. I dont have the tires to get the measurements. Thanks for any help

I would say they are too wide Dave. I know my 28x12.5 ETs have a 10" tread on them. I believe yours are a little over 11" wide so that would be too big for the class.

Do you think the 30X12.5 et street would be within the rules.

According to their tire size chart the tread on those is 10.2" on a 10" rim. It SHOULD work but best to try them out.

Dave, what we will do, is use a go-no-go gauge. Simply a metal gauge with two tangs on each end set at 10.6" inbetween. If the tire fits within the gauge, your good to go. Grab a tape measure, and if it measures 10.6 or less at the tread, you should be good. With radials, a 325 is the largest.
