Semi slick pressure and temps

Recommended Posts

Just picked up a new set of AO50’s in medium compound but I haven’t ran these before. The Bridgestone RE11’s I used to see up to 6psi increase after a session, I aimed for 32psi hot.

 

Is the an optimum pressure or temps with the AO50’s you guys aim for when hot for best grip? They’re 225/45/16. They didn’t have the 50 profile size unfortunately.

Will depend on your setup really but 30 hot is a reasonable base and you should expect a 7 or 8 psi gain from cold.

I found 28 hot works better for my car on the AO50. Starts sliding a lot at 30.

Thanks guys, does side wall profile change  the pressure gains?

it will probably have an effect yes. 

set them at 24 and measure them hot when they come in. adjust them to 30 hot ( don't wait for them to cool down ). you dont want them any hotter than 30-31
