How Wide of Tire on stock FJ40? (1 Viewer)

[rstoddard]

What is the widest tire you can run on a stock (unmodified) FJ40 with a 15x8.5” Wheel? I should note my rear fenders are cut and I have plastic fender wells installed, so it is modified to that extent but not otherwise.

I’m looking to run 33” tire which I have run in the past, but I thought I was running 33X11.5. The tire I was looking at, MAXXIS TREPADOR M8060, only comes in a 12.5 width.

I could consider the MAXXIS RAZR MT which comes in a 10.5 width. Skinny and tall? Any thoughts on going with a taller, narrow tire?

33x10.5 is a great size tire to run. Very common on a 40. Not that skinny honestly. I used to run 33x9.5 , which is the real “tall skinny” size. Those look good too IMO.

Tall and skinny is the way to go. Far more pleasant to drive. These trucks are light, don’t have to worry about load and contact patch concerns.

I ran these tires for a few years, 33x10.5. They completely sucked all winter long I couldn't wait to wear them out and replace them. They weren't bad off road.

I heard they weren’t good winter tires. I seldom drive on snow, and if I do it’s generally off-road unpacked.

I’m in AZ so they would primarily be used in desert rock crawling.

Does the Forum have recommendations for a good off-road MT rock-crawling tire for a rig that is mostly trailered; not a daily driver and not driven extensively on the highway?

I ran a set of Toyo Open Country MT tires that were good on the rocks; very tough sidewall, never had a puncture in all the time I ran them - in places where BFG KM MT's were cut to pieces. They were E-rated (load) tires; one reason why the sidewalls were so tough. The only downside was, the sidewalls were stiff enough that I had to air way down, like less than 10 psi to get them to flex much. Never ran one off the bead going that low though. They lasted a long time too.
