Is anyone running a 325/65/18 terra grappler on a 2 or 2.5 inch level? What rim size and backspacing do you have?

how did these tires fit for you ?

they fit just fine. no trimming or anything was necessary.

That size is a 35x13 and may cause some serious rubbing. If you don't mind hacking up your truck you can make them fit but you may still have some rubbing when turning.

Thanks pawpaw. With 4.5 backspacing, will that make them rub any more or less?

No, thats a 33 inch tire not 35

OP, those run fine even with 4.5 inch backspacing, Ive seen that set-up on several trucks.

oops I was wrong 325/65 is a 35 inch tire, 325/60 is a 33, my fault.

OP, if you go with 325/60/18 thats a 33.5 inch tire and will fit fine with 4.5 inches of backspace. If you go with the 325/65's though that is close to 35 and 4.5 inches of backspace is too much, you would have to go with closer to stock backspacing about 5.5 and you would still get some rubbing.

There is a sticky that says 35 inch tire, 18x9 with 4.5 backspacing will be fine?

My girlfriends dad is running 325/60R18 on stock FX4 rims. I helped him install the 2.5" level and then we tested the tires and the only rubbing we had was when in reverese at full lock and was very little. I did my truck before his and went with 285/75R18 (35x11.5) on stock lariat rims because I thought those 13" wide meats would rub but other than that, no rubbing. Hope this helps ya.
