does anyone know what tyre presures should be,they are 16/53/13 front,20/54/13 rears,michilin slicks med compond,thanks

Do not know about the rears as I have 16/53/13 all round.

I found cold ~13 psi, they gained 3-5 PSI after wizzing around for a few laps so around 18 when hot.

My cars around 420kg wet BTW

I run 18 rear 16 front when warm. I was told 16 all round was a good starting base and fiddle from there.

thanks for replies,i didnt think they would be that low.
