Rocky Mountain Motorsports - RMM (June 27, 2025)
275 front/ 325 rear (stock OEM sizes)
Took a while, but finally got a new PB. Only about 1/10th better than my previous best (which was on Nankang AR-1). However, that day had a strong tail wind on straight and this lap was pretty much calm.
This was with new fronts and used rears with about 4-5 days (e.g. about 100 laps). This actually felt better than with both new fronts AND rears. Just can't get the front to grip with this tire (likely because the widest I can get is 275). Hot pressures 31f/30R.
Have been getting about 3 days out of the fronts (e.g. 50 or so hot laps). Rears have been wearing well 120 laps on this set so far. Almost done, but will probably do another 15-20 laps, so will see what I can do over the next few lapping days.
After that, will try something new. I feel this tire would be so much better with a 295 or 315 front, but none are available.
Mental note: Next time I run both new front and rear, I will try dial out some rear grip with tire pressures.
