Dutch, the 10.50x31 is indeed a direct replacement for the 265x75. (265mm equals 10.5 in.) You 'might' be able to go up to an 11.50x32. This size will be 1/2 inch wider on each side (at the sidewall center), and 1/2 inch bigger at the tire radius. You can compare the clearances you have now, to see if a larger size will fit. A lot will depend on the wheel type you now have (7.5" wide Ford alloys???)
10.50's are a good compromise. That's what I now have on my Bronco.
Good, thanks... I have stock Ford rims , yes alloy but as to 7.5" I guess? Another post in the Bronco forum said the 10.50 is actually not as tall as the 265, said he did a side by side compare. I dont think the 32 will work I was looking at the clearance ,etc and the from well (down) near the black plastic portionof the bumper is maybe, may-be 1/2".
