can anyone explain?

so would there be away of working it out to try and find out exactly what I have one....I'm intending on changing my tyres soon and I dont want to go smaller!!! which would be what i was doing if I had infact not had 255's on

Drop a tape measure from the top of the tyre to the ground. See whether the measurement is more or less than 30 inches.

If you want to see what size they really are, just measure the section width and diameter (without weight on it).

But just get some 255/85-16s for the next tyres.

might do this on the spare as that has all the tread there

ok so I just measured the spare its about 30/31"

So what size would I be looking at for a 32 in metric......sorry I can't even blame it on the hair colour either :D

The most accurate way to measure the diameter is run a tape around the circumference and divide by Pi.
We used to do this with race tyres just to match them up in pairs as they varied so much batch to batch. (as in run a stagger tape around them. We couldn't care less what diameter they were exactly, as long as they were within Xmm in circumference)

The Maxxis 255/85's when I bought them measured up almost exactly 33.3" diameter.

Mongrels are a remould.
The new tyre size is what they glued on to the old tyre.
The other is probably the original size on the original carcass.
Good tyres for off-roading,but wouldnt have them as every day drive tyres.

people you don't need to tell me they are a remould I brought them remember!!! :lol2:

Andy like I said before and feel free to answer how do you fit a 30" tyre on a 32" carcus if that is the case?

Yep this is the only real accurate way of doing it as for tyre sizes i run 33x12.5x15 maxxis buck shots wich are only 32.2in tall ;)
