Well, I'm finally back from deployment. 6 months on the ship and I don't think I have lost the diesel addiction even a little bit. LOL Anyways, I just got a smokin' deal on some brand new Nitto Grappler AT's and I was wondering if anyone was running any 325's on their trucks with only a leveling kit. I was kind of wondering what backspacing and offset I will need for these tires so they don't stick way out. I like it when they stick out a little bit, but not way out. Thanks for any help

 

Give me a week and i can tell you. I got 325 60 18s with 18x9.5 rims. going to put them on in a week. I got a 4.2 back spacing

 

I have 325's on 9.5" rims with 6" B.S. and leveling kit. My tires stuck out 1.5" and kicked up grime on the doors pretty good. Since I installed the fender flares kick up is resolved. I believe a rim with 4" B.S. will hang the tires out pretty fall.

 

I ran 325/60/18 Toyo AT's on 18 x 9.5 wheels with 5.6 or 6 " BS(can't remember), with a 2" Daystar level kit, the outside edge of the tires would barely touch the rear of the bottom front fender when fully cranked. 2" flares pretty much keep the tires inside the fender.

With less than 6" backspacing, tires are going to be way out there, and your brake calipers will be exposed to damage.

 

Thanks for all the replies. Well the guy at the tire shop said they should work very well. I will try to post some pics up when I get them on tomorrow. They will be on some Eagle Alloys 18X9.5 not sure what the backspacing is. I got a pretty good deal on the whole set up, so I can't compalin too much.
