2012 550i Xdrive staggered setup
Will be hopping into a 2012 550i Xdrive. I have 20 inch wheels and was wondering what tire setup I can run without messing up the xdrive system, I know there is a formula or way of figuring it out but I couldnt find anything thru the search. Front is 245/35/20 and the rear is 285/30/20. Thanks.
Emir

245 front and 285 rear on 20" does have a closer rolling diameter than 275's but either setup is fine.. nothing major.

245/35/20 fronts Speedometer Difference: 0.154% too slow with a diameter difference of .15%..............For 275/30/20 rear's Speedometer Difference: 0.834% too fast with a Diameter difference of .83%........For 285/30/20 rears the Speedometer Difference: 0.077% too slow with a Diameter Difference of .08%
The difference in rolling diameter for either of these compared to stock is really negligible and should not affect the x drive at all.. Its when rolling diameters exceed 2.0% and definitely above 5% is not good.

I got that info off of a tire calculator. You punch in your stock setup then you punch in the tires you want to put on and it gives you the rolling diameter difference. Tire profiles usually do have to be adhusted fron and rear to achieve the best rolling diameter that's why the profile in front is 35 and the rear 30. I can't say if the dealer will agree but the rolling diameter difference is so small that if they did make a stink its only because they want to be dicks. It really wouldn't cause an issue with that setup either 245/35/20 front with a 275 or 285(slightly better)/30/20 rear.

Sweet thanks for the info mind sharing the website for the calculator? I just got the car today just waiting for some warmer weather so I can put on the wheels..not a fan of the 245s at all. You running your stock wheels now?

ok. so in us cars have 245 in front and rear? In Norway are 8"x18" 245/45/18" front, and rear 9"x18" 275/40/18" rear standard. and 8,5"x19" 245/40/19" front, and rear 9"x19" 275/35/19" and 8.5"x20 245/35/20 front 9"x20 275/30/20" as option. I vent for 20" for summer and 18" for Winter, I see, 245 in rear givs not a good look???

Do you know if the offset on the staggered version in Norway is different as well? Offset on US version with M pkg is 35mm all around (on 19x8.5) yet 550i non xdrive with M pkg has 44mm offset in rear (on 19x9)

The front (and rear on the square setup) is ET33, not ET35 for OEM 19" and 20" F10/11 wheels.

Here's how you get tire diameters:
245/45/18 245 / 25.4 = 9.6457 9.6457 x 0.45 = 4.340 4.340 x 2 = 8.680 8.680 + 18 = 26.68 26.68 is the overall tire diameter For MPH tire speed based on RPM: 26.69 / 26.00 = 1.0261 1500rpm / 1.0261 = 1461 1461 / 13.211 = 110mph These are very basic easy to use laymen "equations". Your actual overall tire diameter will vary based on vehicle weight, tire psi and quite a few other variables. For a more accurate RPM to MPH numbers you will need engine speed, transmission gear ratio and differential gear ratio. I hope this helps.. |
