Tire recommendation?

To start, I have already spent hours using the search and can't find an exact answer, close but not quite. I am new here and new to Jeeps so forgive me.

I want to go up in tire size on my daughters Jeep. Current setup. 2004 GCL AWD 4.7L, new Rancho RS 5000 all around, 2" Rusty's off road BB spacers, stock 235/65/17. I have a line on a set of BFG Mud Terrain KO 255/75/17 for cheap. Will this work for DD. Just eyeballing it with wheels turned at every degree it looks like these tires may work, just a little tight. Saw a lot of very similar setups in pics on here but I don't know all the lingo for Jeeps so Im just not sure.

Daughter doesn't wheel off road and drives like a grandma. I don't mind a LITTLE plastic trimming to make these fit so that turning and backing is no issue. Our driveway does have some incline(about 10-15 degrees).

If I can't make these work can I go with a 255/70/17 or do I really need to go with a 245/75(or65)? Or maybe get some Overland springs to make those tires work? I really want these tires lol.

Thanks in advance.

255/70/17 would work. You might need some minor trimming.

You're going from a 29" tire to a 32" tire. I had minor rubbing on the inner fender liner with a 2" BB and 245/70-17 (30.5") tires. If she doesn't wheel you won't have to trim as much, but you are still going to be cutting. I'm picking up a set of the Mud Terrains (same size you're looking at) tonight, and I have my foglights cut out, and cut 2" of sheet metal off of the back of the front fenders, and also cut metal in the rear. Now, I wheel my rig, so you shouldn't have to go that extreme. The speedo will also be off. When it shows 60mph, you'll be going 66mph.

Can you go and try putting one of the tires on before you actually buy them?

Both the 255/75R17 and 255/70R17 will likely be much too large for your goal of "a LITTLE plastic trimming". I'd stick with a 245/75R16 (245/70R17) or lower.

If you install overland springs with the BB, you'll be lifted in the 3" range meaning you'll need the extra parts associated with a 3" lift.

Derekmac, Thats what I am going to try and do this weekend. If the guy will meet me at the tire shop I will throw the two fronts on and do some testing. Definitely don't want to trim as much as you have but I get it, you wheel.

Chris, so you think it is simply too much. I am definitely afraid of that. Do you think I will have to trim metal for daily driving or just a lot of plastic. I am guessing the front and rear of the fender wells. Had to trim about 3" in these spots on my truck to fit 35's.

I honestly don't know how much you'll have to trim. On a street queen, I would assume you'd just be trimming plastic. I guess if you're determined, you could always bump-stop the crap out of it if you find they're digging at metal on speed bumps. You'd create a rough ride on bumps but wouldn't have to worry about rubber touching metal.

Anything larger than the 245/70-17 won't fit in the spare tire well.

Well I guess I will pass on the 255's and go with 245 for now. Just too much to mess with at this time but I really appreciate everyones input.

With that being said does anyone know if the Goodyear silent armor tires are any good. I can get a brand new set of 4 245/70/17's for $380…I will offer $350. The reviews read pretty good so it seems like a good deal unless any of you guys think they are junk.

Im picking up some 255/75/17 on jk wheels. Was really just wanting the wheels, but gave me good deal on tires too. Im stock right now, but putting on a 3 inch lift. There are a few members with a 2 inch lift and 32 inch tires. You can stuff them, but trimming will be required. I guess it depends on your preference. And silent armors are good tires. Brother has them on his dakota.
