You did not say how wide. A 32 inch tire can come in multiple widths.

The stock Tires, either 265x70r16 or 265x75r16, when converted to inches are 10.43 inches wide, and either 30.6 or 31.65 inches tall. Both fit a stock suspension with ample room.

Going to a wider tire, at a 32" height, may require a lift or wheel well modification.
The other challenge to a wider tire is that you may be pushing the standard rim width, exposing yourself to a greater likelihood of debeading, in certain (i.e. airdown) situations.

On the topic of standard rim width and tire width. The maximum size you can run on the stock wheels (which at least on my 04 have a width of 7") is an 11.5" wide tire, or effectively 5" larger than the rim width. This is what Discount Tire told me at least. So for example a 10" wide wheel could run a 15" wide tire.

Moral of the story - you can run 32x11.5s on the stock wheels but you may run into clearance issues. I have seen plenty of people run them with a lift (body or suspension). But if you're on stock rims I wouldn't push wider than 10.5 though you may be able to push taller up to 33" if you don't mind potential scrubbing at full flex.

That is one of the challenges I have run into with tire stores. They sometimes make broad assumptions.

Appropriate rim width includes, not only the width of the tire, but the height/stiffness of the sidewall as well as the ply and rubber compounds. Thus, the engineers at BF Goodrich say the rim size for my KO2's 265x75r16 (10.43") should be between 7 and 8", while the same tire, in a 285 (11.22") width, should be run on a rim not less than 7.5 inches wide. I know there is safety factor built in, but I gotta go with the engineers that design them over the mechanic who changes them.

That said, your tire may vary!!! LOL

definitely a great topic of discussion, however!!

Might that be because of your rims or that you are a Gen1. I had been running 265/75r16's for a weeks before I lifted it, on stock rims and it never rubbed a bit. That is actually the stock tire for certain frontiers (pro-4x and desert runner)
