tire question 275/35/22 all around?
 

So i'm trying to figure out some new tires on my 2011 X5d

Getting some 22" 215 replicas, 9.5" all around, a couple of questions:

1) I know a 265/35/22 would work, but how about a 275/35 (do they make this size) or 285/35?

2) Does it make sense to run staggered tires sizes even though the wheels are the same size? say 265 front and 295 rear? using some 15-20mm spacers in the rear? or should i stay with the same size tires all around and then use spacers in the rear to fill out the wheel wells?

anyone? what is the largest tire that can clear the front?

295/30/22 is the optimal size to run in a 22" it is almost exact to the factory BMW size:

255/50/19 29.03" 716.5 revs/per mile
295/30/22 28.96" 718.2 revs per mile


Only issue that you will encounter is the 295 is a bit wide for only 9.5" rim. Can be done, however will look a tad bubbly on the sidewall. Your best bet may be run the 265/35 all around with a spacer in the rear on 9.5" rim..

275 and 285 will not work out and can cause some issues.
