Ok, not the usual 'what R my tyres meant to be blown up2?'. I know that
I have fitted 15" wheels on the back of my 'bus with massive tractor style 235/75R15 tyres. What pressure should I be looking at running them at? I would imagine less than factory pressures as they have a much bigger footprint but I'm open to suggestions

When I put the tyres on, I popped the bead on and shoved some air in, put them on the van then blew them up. One looked fine, but had 13PSI in. So I'm thinking a lot lower than factory..

Cheers,

35 to 40 PSI should do it.....and then see if they wear evenly...wearing edges means too low pressure, wearing the centers means too higher pressures.

I run mine 2.5bar front and 3bar back on 15" wheels
and the tyres are wearing OK
