Took my first runs on 205/45x16 A3S04s last weekend. I was running 38f/42r cold on a 60 degree day on sealed asphalt. After 2 runs 42f/44r. After 3 runs 44f/44r. There was about a .5lb differential from right to left after the runs.

I know I had some wheel spin due to using too much throttle in a big sweeper. Causing some of the rapid rise in the front temps. The edges on the fronts show some wear as if they were under inflated. I was able to get the rear to come around fairly well until my last few runs when the pressures were almost equal.

I wanted to drop the fronts as they got warm but given all the wear at the lower pressures I was concerned I was rolling over on them too much.

I had several other drivers telling me they were running close to 50lbs on their Hoosier but they drive much heavier cars. Anyone willing to share their experience with pressures on a Mini?

 

RS04's 53 F, 48 R.

Thanks for the information. I had missed the 2nd page of that post.

I'll try raising the pressures during test & tune Friday and see how they do.
