Hey Busdriver,

I have been running 225-75-15's on stock steel Tracker rims for three years now with no rub and no problems.  I run 30psi on the highway and 12psi on the trail.

I'd like to get a set of 235's but these things just won't wear out...

and these are the 15/5.5 rims or the sami 15/6 inchers??

I went to two shops  and the would not mount 235/75 B cuz they would fall off??? oh yeah I was looking at the bds 2 inch lift...what size tires can i put on.....I am just a trail driver not a rock crawler

stock steelies any different than stock aluminum rims?

Go try the least reputable shop in town that's how I got mine mounted.
I'm running 235/75/15 on the stock samurai wheels 15x5.5 seem to fit fine I wouldn't go any wider on the wheels.
You can get 215/85/15 swampers from interco.

I think from what I've heard and seen you should not go wider than 9.50 on the width of the tire unless you get a bigger rim.
