COMMON TYRE SIZES

I would say that 265/75s are more easily found in remote areas and they are also chaper to buy new than 265/70s. I use BFGs and have found that there are more outabck tyre places now stocking them whereas this wasn't always the case. If you have two spares you should be ok to get to the nearest major centre. I currently use 275/70s on the GU but will seriously look at changing to 265/75s when it comes to new ones.

Ive never had to buy a tyre in a remote town anywhere, on any of the trips Ive run, and none of the vehicles I have taken with me have had to purchase one either, but they all run a quality aftermarket tyre suitable for the purpose and not OE.

You could consider 750 x 16. This is by far the most commonly used tyre in outback areas, and are extremely effective in most going.

probably the easiest tyres to get are 7.5x16 or 235 tyres but if you can remove a tyre and have some tubes and those large tyre patches for emergencys then that should see you right if things dont go as planned

Cruza,

Go the 265/75.
I've run the 265/75 Goodyear MTRs on mine now for 35,000km without any issues, and they have done a heap of outback stuff, and still 9mm tread left.

I use that size because it fits nicely on the 16x7 rims, come with stronger LT construction, and they are the same diameter as the common 750R16, or the 235/85R16. The latter can be fitted to your 7 inch rims if you had to. Most brands of 265/70 are P (passenger) construction, and have lower load index.

Some of us carry a split rim with 750R16 as a spacesaver extra spare.

the mags which come with the 79series RV look pretty strong, so I'd be inclined to use them. I wouldn't personally drop back to split rims - used them for many years, and happy to see the end of them.

Cheers
