Wheels/Tires

Hoping to upgrade wheels within the next few months and searched the forums but didnít really find the answer I was looking for.

Thinking about adding 20ís whether aftermarket or OEM and wanted to know what the tallest sidewall tire I can squeeze on them. I donít really like the look of the tiny/small sidewall and want something a little more beefy for the comfort levels as well.

So if youíve got 20 inch wheels on your car and non-low-profile tires what size did you end up running?

Any pics of 20Ē setups with higher profile tires would be icing!

Thanks!

Hello I too am looking to upgrade to 20" staggered wheels. Research I've done turns out to utilize as close as possible to stock diameter tire circumference. On my vehicle, it is 27.6, which will not effect the speedometer or cause issues with transfer gear case. I found that Chevy Camaro SS V1160 Staggered wheels are plentyfull and reasonable. Your going to have to look for tires that meet your stock diameter circumference for your model X3. They vary from 17, to 18 which are standard on my model or the option 19s. Keep me posted.

I've got a set of 6 series 373m's I'm thinking of selling (pics in the FS section) that were going to go on the wife's Mtech e83 but we ended up getting her an e70 instead. I always thought it would look nice but we never picked up a set of tires to test fit.

2007 e83 30SD Wheels/Tyres

Hi All,

New to this forum, so first post.

I was wondering about tyres after reading about the x-drive sensitivity:
  • I have a 2007 e83 30SD running the standard staggered 235/50R18 in the front and 255/45R18 in the back.
  • It became rapidly clear why the previous owner sold the car to the garage as two weeks after buying it the trifecta of lights came on. I changed the transfer case fluid and replaced the actuator nylon wheel and all is well. I suspect the previous owner put wrong winter tyres on it and upset the x-drive system and then replaced the summer tyres on it and quickly sold it...
  • I bought the car with winter wheels which are a square setup: 245/45R18 Pirelli Soto Zero (not * rated).
  • The winter alloys are also 8Jx18H2 ET45 when I believe the original BMW summer wheels are 8Jx18H2 ET46.

Would anyone be able to advise me on what to do:
  • Can I run these winter wheels as they are, or should I replace the tyres to the recommended square 235/50R18 on the same alloys?
  • As far as I can tell there are no longer any * rated winter tyres available (Dunlop SP Winter Sport 3D). Which tyres are proven to work?
  • Does the 1mm offset difference in the alloys make any difference?
  • My summer tyres are Dunlop SP1, which are the only recommended * rated tyres for the staggered setup. When I run it through the wheel size calculator, I get a diameter difference of 1.2%, which seems large... Should I run a square setup my next tyre change? Strange that BMW would recommend such a setup on the notoriously sensitive x-drive system...
  • I love the Michelin Primacy 3 tyres (and the Alpin 5 winter tyres), but they are not BMW rated, but I suspect they could be ok in a square setup, is this true?

Thanks for your input,

Dan
