Default Tire Pressure Advice for Track

I need tire pressure advice for Dunnville Autodrome



Tires: Toyo RA-1 (shaved) 235/45/17
Car: 06 WRX Stage 2
Suspension: Lowered on Swift Springs, everything else is stock

I have access to one of those dinky portable 12v air compressors at the track.

Suggestions would be appreciated.

From my experiences with RA-1's they like to be about 38-39 hot. 40 hot is OK, but anything above that and they fall off quickly. I'd suggest starting with cold temps of 31 front, 33 rear and see what the tire temps are after that. There are a lot of variables that will affect the tire temps including alignment, suspension setup, track config, and driving style.

I have no experience with RA1's, but with RE01R's and Azenis I found that 38 hot all around provided a very neutral balance.
