Hoosier R6 on 2011 E90 M3

Does anyone here run Hoosier R6's on their E90 M3's at the track and what cold and hot pressure do you feel is best? The Hoosier people suggest I run 34 front and 32 back as a starting cold pressure looking for another 8 to 10 on top of this for an ideal hot pressure. Seems kind of high to me. Looking for experienced advise......

I run slicks, but I agree that the pressures for the E92 are higher than other cars I've ran. It's a heavy car. Part of the problem is managing outside tire wear unless you have 3.5+ camber too. I run 31-32 cold and try to keep it at high 30's (bleed down after session). I'd run a little less if my outsides could take it, but at 2.5 camber it eats them. Listen to the Hoosier techs.

I ran 26 cold on my E36, and mid 30's hot, but it weighed 1000lb less and had more camber.

Hoosier guide calls for in the neighborhood of 38-40 hot depending on alignment, tire, track, car, etc. no substitute for a pyrometer. They know their tires well

In my soon to be former e36 race car (IP and IS trims) I would start the R6 at 30-31 cold and shoot for 38-40 hot.

Next season when I start tracking the e90, I will use those temps as my starting point and adjust from there.

I ran BFG Gforce R1s and 32/34 was where I started cold, looking for 40 something hot. Summer, I would try and hold around 42, winter, or cooler weather, 40 seemed to work best.

2011 BMW E90 M3  [5.00]
2013 BMW 328i  [5.00]
Where I start with 30psi cold in my E46, I'm going down to 28psi cold on my E90 in similar morning temps. That puts me at 38psi cold on street tires.

It was about the same with the conti scrubs and R6s when I used them.

+1. Looks like the OP is on ZCP. Keep an eye on your tires or they may cord very quickly.

+1 on pyro. The proper way to measure and adjust the effect of camber and tire flation.
