I have a GQ 4.2 Diesel and am in the market for either MTR's, MT KM's or STT's (read the archives and still trying to make up my mind)
My options are 32x11.5 with 15" rims, 265/75 with 16" rims or 235/85 also with 16" rims. Either way I need new rims from current setup (rust spoted sunny's).
Is there a difference in performance or other, between each tyre size option, particularly the 2 wider versions.

Also opinions sought on running 33's on a GQ Diesel. If I went that way what issues do I face with performance or mods needed to run them.

I run 33's x 12.5 x 15 on 8" sunrasias without a hassle in the world........ No scraping........A consistant fuel economy of 12.6 L/per 100kms.........I have done 35,000kms on them and they are ½ worn..._____________________________________________

15 inch rims are cheaper, but the tyres are not as strong. If you want good reliable tyres for offroading, go for the 16 inch. The load indexes of the 16 inch sizes you mention will be around 120 (10 ply tyre).

16x7 rims are ideal for a Patrol and fit both sizes you mention. Prado 16x7 rims would be ideal if you can get them. The stud spacing and offset are perfect, just be sure the centre hole is big enough. If you're mostly doing desert trips, then go the 235/85R16. If you want a better handling tyre, go the 265/75. Fuel consumption might be a tad better with the 235/85.

The three tyres you mention are all good choices. I'm very happy with my 265 MTRs after 13,000k.

Wider will use more fuel, more tire to move to start with, wider is better in rocky, thinner can be better in mud

a 32inch tire is a 32inch tire, 15,16,17 or the new 18inch rims.

MTR best all rounder
STT better in mud
KM's better in the showroom.

33's will change your gearing, speedo will be out, and you will lose low end power...
