No I don't drive a MS6, but figured you guys knowledge on AWD systems could help.

Just trying to get all the right info before I make a purchase:

Wheels are -
Front: 19x8.5 offset of 32mm
Rear: 19x9.5 offset of 35mm

Is anything under 1% diameter difference legit? I'm looking at 235/35R19 in the front and 265/30R19 in the rear which is a 0.87% difference. But moving to a 275/30R19 is only a 0.08% difference. I used http://www.1010tires.com/TireSizeCalculator.asp And I'm AWD. Thank you for any assistance.

No input?

I would advise against it. Speaking generally, all-wheel drive systems are happiest with the diameters are analogues. If not, you obviously have front and rear axles spinning at different rates.

You're talking about a pretty small difference in overall rolling diameter, but if it was me, I wouldn't risk it. Just pick up 4 of the same size wheels and tires. You can alter offset front/rear and it's not a problem, if fitment is a concern.

i know different diameter wheels on alot of newer cars will mess with the traction control and ABS some as far as they realize the problem and become inoperable untill you get the same diameter back on

It's just the conave look of the 9.5's is what I'm after. And 9.5's in the front will be a tad hard to pull off.

ive never heard of anybody pulling off 9.5's

not saying it cant or hasnt happen. and 19's to boot..

Just to clarify, I'm in an Audi A4. I was asking the MS6 crowd (or anyone that wants to chime in really) since I knew they were AWD too.

.08% is nuthin. You could get that difference between front and rear after driving 1000 miles the way most of us drive.

They don't have a higher offset in the 9.5 that is still concave so you could fit them better? And with a 30 series profile that will give you a smaller sidewall so the tire will be less of an issue.

Not in my bolt pattern. But from most of my findings, since I'm not dropped on coils I won't be as low as those that have run into problems. But that leads me to wondering how the set-up will look with my 1.4" drop.
