AWD and Staggered.

Thinking about 315/35/22 up front with 325/35/22 out back. The tires im looking at are 30.7 up front and 30.9 in the rear, does anybody know if this setup will adversely effect the AWD system? .2 difference. Thank You

Why do that though? I wouldn’t do that setup.

Just tossing around that setup, instead of 285/40 up front. 315/35 square would be perfect if I was lowering but im not. 325 out back gives me a little more tire.

I personally wouldn’t, I wouldn’t like having two different diameters, even if it’s a small difference, on an AWD vehicle. Just go 315/35s all around and call it a day. Nothing wrong with that.

Can't think of a reason good enough for ME to do what you are suggesting. I'd run 4 tires of the same make, same model, same size and the same amount of rubber on the tire. I might feel differently if I had a new set of tires and ran a nail through the sidewall of one with only 1000 miles on it. That would be about the only exception I can think of.

You may get by with what you're considering just fine, but think of the number of $$$'s that could be involved should a drivetrain problem develop. Idiot lights and computers are there to protect you, and they might, but what if they don't? Play silly games, win silly prizes.

Then again, do it report back and the rest of us will be able to give a solid answer next time someone asks.

I’ve had two cars that came with a staggered setup. My CTSV had big rear tires but was RWD. My wife’s 2025 GLE450 also has bigger fatter rear tires and AWD. Both cars looked really good with the staggered setup. The downside is you get less tire life because you can’t rotate front to back. Since both my wife’s car and my ST wear the rear tires faster than the fronts and are AWD I’m guessing you would be replacing the rears twice as fast.

When I was tracking the CTSV, I had a square set of wheels and tires. Got a lot better mileage out of the tires by rotating the.

The rear tires are traveling roughly an inch more than the front for each complete rotation. The smaller tire is going to make roughly 4 more revolutions than the big tire for each mile traveled. Is that enough for the computer to pick up on? I don't know.

According to my tire size calculator, the difference in his sizes is 1% circumference. I was thinking before checking that under .5 would be fine and 2% would be no good. Just a guess. Without knowing initial design specs, I would be concerned with a 1% difference on an AWD.

I don’t recall the exact difference but my wife’s awd staggered tires are almost dead on circumference front to back.

If OP absolutely wants to go staggered, you can do a 325/35r22 and a 275/40r22. Same exact diameter.
