Biggest sidewalls that will still fit fenders/spare well
So, I have a 2012 Overland with the ORA II package. It came with 18" rims and 265/60 tires.
I would like a thicker sidewall for off-roading. A bit wider tire, too, if it will fit. I don't mind removing the bins from the spare tire well, but I would like to be able to close the lid.
I would like to buy 5 tires. I do not mind getting a spare tire that is a different size, as long as the outer diameter is close enough that I could still drive ~100 miles on it without screwing up the 4WD system.
What is the largest size I can go with? I am concerned that even tires sizes that people say "fit" the wheel wells without rubbing while the car is driving through a parking lot will still rub when the suspension is more deflected off-road.
