Running 38psi all round now.
Seems like a good call.
Apparently, low profile, higher psi. That's what i was told... here and out there. Even 40psi would be ok.
Has to do with the sidewalls being less able to support themselves, higher psi helps keep them in check.
something like that anyway. plus i'm running nankangs, and these have got weaker nylon sidewalls, apparently.
So cowie165, maybe 40psi was ok. Have you had any probs with uneven wear (in the middle) at that pressure over the last year?
