Tyre Sizes???!!

[TASR12]

I know there are some posts on here but I couldn't get an answer to my pretty simple query. I've got 31x10.5xR15 BFG AT's on my '95 SSRX. What is the difference between those and 265/70/R16 and which would be better? Presumably the second one is on a bigger alloy diameter wise so would it be worth changing up to?
Thanks in advance for helping me with a simple issue!!!!!

I am fairly sure your vehicle should have 16" rims as standard.

Anyway have a look here -

They are definitely 15's but I know what you mean everyone else seems to be 16's. The aren't factory wheels, the previous owner changed them so am I missing out on anything by having those tyres?

Is it actually a 3rd gen or just a late 2nd??????

if its on 15" wheels then it has to be the late 2nd gen

[TASR12]

It is a 2nd Gen. Just wondering which is the better tyre size although there doesn't seem to be much in it size wise.

would it be worth changing to the 265/75/R17, anyone?

[charvell]

its supposed to have 15 s onit Is the truck loifted? and why do you want the change them? if its for looks just do it..

[stormforce]

the 31's are slightly bigger than the 265's and the 31's fill the arches and look better

Spot on, just the advice I was looking for.
Cheers.
