I am getting new tires/wheels in the next few days, and can't decide between a 325/65R18 or a 325/60R18 Nitto Terra Grappler AT.

The truck has a leveling kit on it and is otherwise stock.

The wheel I am going with is a 18x8.5 with a +25 offset.

Here's the sizes of the tires in question:

325/60R18:

32.99"x12.83", 7.5" sidewall height, 3000lbs@65psi load rating, 630revs/mile

325/65R18:

34.88"x12.99", 8.44" sidewall height, 3195lbs@50psi load rating, 596revs/mile

Compare that to the typical 315/70R17 H2 take-offs:

34.5"x12.0", 8.75" sidewall height, 3195lbs@50psi load rating, 601 revs/mile

Which Nitto tire should I go with, and why? I am going with an 18" wheel, so the BFG's are out of the question.

Will the 325/65 be too large to fit, even with the narrow and properly offset wheel? I'm going to see if they will test fit one first, hopefully they will.

Thanks

Bump for this thread as I am searching like a mad man trying to find pics of a leveled truck with this size tire on it.

 

Depends, If your going for the look, go with the larger tire. You might have to trim the plastic off the front and back of the front wheel wells by about an inch. If your going for a little better than stock but keep performanc and mileage go with the smaller tire. I sometimes wish I had gone with the terra grappler A/T 33.2" diam. with a leveling kit. Don't forget to have d/c reset your speedometer, truck drives/shifts better when it's set right.

No rubbing at all, even fully locked and climbing a curb.
