If anyone is running Toyo R888's on their Boss I am trying to figure out what the right tire pressure is. I am currently running 40 PSI hot on all four tires at the track.

Agreed, the R888 does not like heavier cars like the Mustang. AI reverted to the RA1s after trying to switch to the 888s. They just go away too quicklyboro92 said:I know I'm not much help with these comments, but careful with those tires.
They get greasy quick and don't like much heat.
Used them on a 2400lb car running 30psi and it got greasy after about 4 hard laps at my local circuit. I think something like 40hot front, 38hot rear is a good starting point.
Flyboygsxr said:On the Toyo site it recommends 32-38PSI hot...I found that running any lower than 36 with a heavy car like the Boss causes the car to move around a lot because of sidewall flex. I have experimented a lot with the tires and for my setup I like 38 front and 36 rear. I might go 36 front and rear for a session this week and see if that cures some of the understeer. I am going to dial in some more negative camber as that helped also in previous track days.
