One of the best testaments to a well setup car (besides great handling) is even tire wear.
I put new tires on Barney in October 2018. Since then I've run 2 SCCA Autocross events (one with a co-driver plus fun runs\20 long slalom intensive runs), 1 Good Guys event, and 4 more SCCA autocross events. I haven't rotated the tires once during all of this.
Today I took them off the car for inspection and was impressed enough with the even wear across all four tires that I thought I'd share.
You'll have to look close at these pics and know what to look for but if you pay particular attention to the center rib on each of the four tires, you can see how all 4 of them are wearing very VERY evenly...
I'll probably rotate the rears to the front as there is just a bit more wear on the rears (probably just from the Good Guys event) and these should last me thru most of the summer at this rate.
If I really wanted to extend the life of these, I'd pay to have them flipped on the rims...and that's probably not that bad of an idea either.
