I'm looking at getting a set of wheels. I was sure I was going to lower it with MSS but after hearing about so many people having issues I decided against it. Don't want to go H&R and sacrifice ride quality. Instead I am going with a higher profile tire to fill the wheel gap some. I had trouble finding the exact tires sizes I wanted but found Michelin PS4S in this set up:
Front 22x10.5 285/40/22 Rear 22x12 325/35/22 It puts the overall diameter of all 4 at 30.9". Has anyone tried going with bigger sidewalls? Any feedback or negatives anyone has experienced? |

If it's not broken don't fix it. German engineers know what they're doing. The height is not an error, changing things will have consequences. That my opinion.

when you're changing tire sizes from OEM, it's recommended the new tires be within 3% of the height and diameter of your original tires. going beyond that puts serious risk of premature AWD drivetrain failure.
it's more than simply "will it fit?" it's "will it be safe and function properly?" it's best practice to mount OEM approved sizes for your particular vehicle. that being said, I remotely recall a couple guys who installed larger than OEM sidewalls claiming no issues. |

Larger sidewalls on the same rims will give a very different look to the whole vehicle. Can you get tires to fit? Yes. Should you? Maybe not. Its just a few millimeters we're talking about but it makes a world of difference. I dont think you'll be happy with the look and the ride wont improve all that much. I installed the H&R's and have zero regrets. Between the H&R's and the spacers, the truck now looks soooo aggressive and beefy. Ride quality certainly did not suffer. I would hear about it everyday if it did as it is my wifes daily. I strongly recommend against the increased sidewalls. i think youll regret it.

OP, I thought about doing this but in the stock 21/22 sizes they are still really no tires available at the size above (35 and 40 sidewall instead of 30 and 35), either. The amount of gap on these cars is stupid.....there is no reason for it and it takes away from the look. That and the quiet exhaust are the 2 things I hate the most about the X5M....I honestly which I had gone M50i at this point.

No, it won't throw off your speedometer. Remember, people say BMW actually overestimates your speed by 3-4% on the speedo from the factory.

of course it will. regardless of an overestimated speedometer or not, you have a starting point and once the rolling circumference changes, there's a delta produced. (OEM 275/45R20 versus non OEM 285/40R22 shown below)
