for you guys that run winters...

you guys that have OEM 19s and go down to 18s for winter, are you guys using 225/45/18?

I step down even farther to 17" for cost savings and more sidewall.
215/55/17
The narrower the tire, the better off you are.

yup 17's . clear the front calipers by millimeters. on my 13 x1 msport. sure do like the softer ride compared to the 19 in rubber bands

I run 225/45-18, but I'd also consider 235s as well. 245s would look nice, but would be less than ideal in deeper snow. I don't know, I might enjoy the dry performance of 245s if I was running performance winters vs. full-on snows.

neverdone · 10-06-2016, 11:27 AM

ya I was looking at the thread about people wih 17s, but I'm thinking I want to stick with 18s. I'll probably see some deeper snow here and there, so 225/45 is probably my go to.

thanks boys.

Crap I didn't think about that, I'm putting 35i brakes on my 28i.
Is the clearance close on the face of the wheel or the barrel?

critter · 10-06-2016, 01:37 PM

brake caliper is the tightest clearance on the inside of the wheel(barrel?) with a i35 x1 m sport. but they do fit and worked great in last years snow

Thanks, hope mine clear, I didn't even bother to check that when I test fit the brakes.

I step down from factory 18s (225/45/18) to 225/50/17s. More side wall and the tire calculators state it's only about a 4% difference in diameter. Which is pretty good for the speedo and my OCD.

FWIW we are running 18" in both summer and winter. Being they are not run flats we can toss one in the boot for long trips.

17" during winter, staggered 19" during summer.
The wheel well doesn't have good clearance for larger than 17" if you live somewhere where frozen sludge will stick. The larger sidewall (more air volume) also helps when driving over ice chunks.

For nordic conditions, the X1 is not ideal - there's no room for chains in the wheel wells, regardless of wheel diameter. And no way to switch from AWD to non-differential 4WD. And the tow point is only on one side of the car.
