Hello,

I am gonna be tracking my integra this weekend and wondering what the recommended tire pressures are for a 195/50/R15 R1R?


to be off topic, I also have azenis rt615 but I wasn't sure if I made the right choice to be tracking the R1R instead of the rt615. the last time I tracked with the azenis, i felt that the grip was compromised as they get overheated towards the end of the day. this is the reason why i chose to run the R1R over the azenis for this coming weekend.

 

I would suggest calling toyo. I can tell you on the R888 I run they suggest 40lbs HOT.

 

Why are you running an undersized tire? 205/50-15 or 225/45-15 would be much better sizes for the car.

Ignoring that, you'll need to find the optimal pressure by observing how far into the sidewall the tire rolls.

And if you went with a different tire to get away from heat causing traction issues, you probably chose the wrong tire. The R1R is known to only stay grippy for lighter cars that don't put too much heat into them.
