I have Cooper Discoverer AT3 tyres fitted to my JL, recently been reading threads about pressures and dealers filling too high. Mine are at 38-39 psi and was wondering if anyone could tell me if that's about right or not for on-road use? My tyres are 275/55/20.

Cheers!

P.S. Please don't bite my head off for having 20inch wheels...!
