I have access to a set of 325/65/18 Terra Grapplers for my 03 4x4 SuperCrew. It is not leveled or lifted.

Id Like to mount these on 18" 02 Lightning Rims.

Nittos Web site Shows the Dimensions of these tires at:

34.88" x 12.99"

Is this just too big? I would imagine without a leveling kit, I would rub the front plastic fender piece... But with a leveling kit, could I get away with it?

They are basically slightly under 2" taller than the 60's and just a hair wider (hairs?)

Am I crazy?

 

You will need at least a 3 inch body lift to fit those, along with cranking up the torsion bars.

 

Ok so let me get this straight -

For 2" more - I need a three inch lift plus a little.... but on the 325/60/18 I don't need anything???? I don't get it... You mentioned in another thread that 325/60/18 would fit stock (maybe a leveling kit) - You sure these won't rub (up and down) - not the steering stop issue.

 

I've seen one stock 4x4 with 325/60-18's on 18x10 wheels. It was on Trucks TV and Stacey had to trim a good bit off the front bumper's lower valance to fit them. 33's are a tight fit on a stock 4x4, just like 35's are a tight fit with a 3 inch body lift (using aftermarket wheels). Remember, wheel size and backspacing are as important to fitment as tire size. For instance, I installed 285/75-16's on my Screw at stock height. Using the OEM 16x7 inch wheels, they were not even close to rubbing. When I changed to a 16x10 wheel, I had to trim about 1/2 inch off my front bumper's lower valance for clearance.
