xDrive Tire Sizes?

theinfamousdrew · 03-28-2014, 09:35 AM

Hey guys,
I've read serval threads at this point and can't come to a conclusion.
Will having a different rolling diameter screw with the xDrive system?

I'm picking up a 2013 335i xDrive M Sport with square 225/45/18's.

I'm looking at buying one of two sets of wheels with tires.

Set 1:
F- 235/35/19
R- 255/35/19

Set 2:
F- 245/35/19
R- 275/30/19

From what I can tell I'll have to buy different tires.

Set #1 is too far off for sure. Set #2 is close enough, probably will not have issues but still not an exact match.

If I had x-drive I would run a square setup

Agreed.

Should be 235/35/19 and 265/30/19, or 235/35/19 and 275/30/19.

theinfamousdrew · 03-28-2014, 02:51 PM

From using the tire calc I came up with
225/40/19
255/35/19

These sizes are way off according to the calc.

225/45/18 - 265/30/19 = -2.821%
225/45/18 - 275/35/19 = +2.281%

theinfamousdrew · 03-28-2014, 03:04 PM

Should I be comparing the original tire size to the new one and be <1%?
Or are you comparing the fronts to the rears?

VMRWheels · 03-28-2014, 03:36 PM

Sorry, but these are for an F30, correct? They do use one profile larger than the E90/E92. 225/40/19 and 255/35/19 are standard specs for them on a set of 19s. I thought you were looking to put them on something like an E92.

You want to have the overall diameter with your wheels and tires within 3% of your factory specs, however what's most important for staggered tires on an AWD car is having the front and rear tires within 1% of each other. So if both front and rear tires are 2% smaller than stock, but they are exactly the same height, it's fine.

You forgot the 225/35/19 and 265/30/19.

You compare front and rear tyres and difference needs to be under 1%.

AH HA! Thats the missing link.
Thank you for the clarification.

theinfamousdrew · 03-28-2014, 05:03 PM

New question.....

Will these fit on the rear......

F30 335i xDrive
255/35/19 x 9.5 ET33

LeeCatD8209 · 03-30-2014, 10:10 PM

I just need a quick recap/clarification.

The overall change in diameter wouldn't be such a big deal, as long as the front and rear were the same height, or very close?

Yes the reason it would be a problem is because the front and rear axles can't be moving at different speeds on an awd. 1% difference is what is considered safe. 245/35/19 and 275/30/19 are just over 1% so they are either close enough or could possibly cause some problems. If you really wanted those sizes you could probably get the front tires shaved so the diameters are closer.

I admit i have never heard of that.

LeeCatD8209 · 03-31-2014, 02:05 PM

I've got a 17x9 and 17x10 staggered setup I want to try to run. I was looking at running a 285/40 in the rear, and a 255/45 in the front. Planning to run very little to no stretch.

I would not recommend that sizing on the back of an F30. 19x9.5 ET40-45 is a pretty flush fitment as is. That's going to poke out past the fenders a bit.

mweisdorfer · 03-31-2014, 08:31 PM

Whatever tires you choose, you will be going through tires every 30-35k because the size differential from front to back does not allow you to rotate them. In addition, x drive and AWD tend to eat tires.

If you go with 19's, they will look cooler but they will cost more $$.

I would suggest a z rated tire vs a w or y rated. You may get more miles out of them.
