My LR2 has 19" wheels and I want to get tires that are better suited for off-road. The only ones I can find are these Cooper's, but the size is 255/55R-19. Specs say I should use 235/55R-19. 10/10Tires.com says the 255 size is not guaranteed to fit. Seems to me they should, so was wondering if anyone has used 255 and if they were ok. The 255s are only .86" taller and .75 wider, and there is plenty of height in the wheel wells. What do you think? Thanks.
