Couple things I learned at the tire test...

1) That little arrow doesn't mean a damn thing. Has some other meaning that I can't remember, but not what we all think it means.

2) I've been close, but need to run a couple more pounds than I have ever run because I let the tires roll too much.

There is a separation line that you can just barely see in this photo, just above where that arrow would be pointing. But probably 1/4", or so, higher than the tip of the arrow... Hot Rod - Michelin Pic

That's all the further the tire should roll. That's the separation line from where the contact rubber is bonded to the sidewall rubber. Past that and you are into less sticky material.

Basically I have been running to about the arrow like you... forever. I've never taken temps, but by your temps, it looks like if you raise the pressure a couple pounds you will probably get the tire over where it should be.




I've got the fronts at 38 PSI, though I started at 32. I'll try higher and report back. Thanks for the tips.

LOL - I think this is a great tire. It may not be the 'top dog' on the hot rod tire test, but it's won a number of other tire tests. It gives great feedback and performs well when wet.

That said, my next set of tires will be cheaper. The HPDE event manager recommended the HTR Z III, so I'll probably run through a set of those next.

I want more track time, so cheaper tires will help that happen.
