Different TIRE SIZES?

[bamaboy473]

I'm running 275/65/20 Nitto Dura Grapplers....really quiet and comfortable, but the fronts rub the wheelwells during hard-over turns.

I'm thinking about getting some 275/55/20 for the fronts.

Will having 275/65 on the rears and 275/55 on the fronts cause any problems?


2000 F350XLT 2WD and not raced or off-roaded, FWIW

the only problem I can foresee is with tire rotations.

x2 on the rotations. Wouldn't wheels with greater backspacing be easier?

[bamaboy473]

What's backspacing?

What are you rubbing? The inner fenderwell or the leafs?

If the inner fenderwell - the black plastic behind the tire - just zip tie it back out of the way. If the leafs - well then yeah - live with it - change the backspace - or different width tire.

Only one rotation before the rears would need replacing, and then go with the 55 aspect all around.

I don't see a problem with the 55s on the rear and the 65s on the front, do you?

Sure, if you want to look ridiculous.

But other than that, tires are meant to be rotated front to back, not left to right (for cord pattern)

So, the choice is yours. Not something I would do though.

DO NOT stager tire sizes..i highly do NOT recommend this. it will actually bind up a transfer case..ive seen them wreck at work, also ive seen diffs pile in due to stagered sizes..iit screws with everything..

just get the stock tire size or just buy spacers..

Well, looking ridiculous has become real easy for me as the years roll on, so that's not a problem

Guess I'll have to stop by a tire store, because I'm thinking that there can't be much more than 1/2" height difference between the 65 and the 55 series, so it would take a hell of a trained eye to even spot it...or am I missing something?

Your missing something. Typically the difference isnt 1/2". On truck tires - the difference is usually 2+ inches! An example, generally speaking, a 325/60R18 is a 33" tire. A 325/65R18 is a 35" tire. That "little 5" makes a big difference.

Have you by chance looked at the Nitto Tire Website for the Dura Grappler - it answers your questions on height without guessing

The 275/55R20, load range 117H (not much) and is 31.89" diameter.
The LT275/65R20, load range 126R (alot) is 34.05" diameter.
