X5 E70 wheel diameter max variation, Staggered 22"
Hey all,
First time poster here with a question regarding the maximum diameter variation between the front and rear wheels on my 2012 E70 X5 x35i Ive done a fair bit of research here but havent found anything definitive on what the limits are. My concern is with the Gearbox/transmission. Ive purchased a set of 22in wheels, 22x10.5 Front, 22x12 Rear and am now searching for the best tire combo. Stock my X5 had 275/40-20 Front, 315/35-20 Rear which gives a Diameter Variance of 0.07% (728mm x 728.5mm), basically identical. The common set up I see on a 22in wheel is either: 295/30-22 Front, 335/25-22 Rear = Diameter Variance: 1.29% (735.80mm x 726.30mm) or 285/30-22 Front, 335/25-22 Rear = Diameter Variance: 0.48% (729.80mm x 726.30mm) My preference is to go with the wider front tire (295/30-22) to avoid excessive stretch (not interested in the stretched look) on my 22x10.5 front rim. What level of diameter variance is acceptable? Ive heard anything from "no more than 1%" to "anything under 3%". Ive seen a lot of 22" set-ups similiar to the one I've planned... anyone ever hear of issues? Thanks!! |

Man I did a lot of searching and at one point I knew off the top of my head...but it has been awhile. I think 3% is max but in the owners manual I thought it even talks about new vs worn tires front to back is a no-no
Obviously less difference will be better, 285 on a 10.5" will not look stretched its right on for fitment IMO.

I did end up going with the slightly narrower tire (285). Im really surprised this topic isn't talked about more...then again I may be looking in the wrong area. Again, thanks for the reply |

hoping you guys can help
Hi there, im a first time poster here too so please accept my apologies if im crashing your post!
I have bought a set of AXE EX30's (9x22 front ET20/10.5x22 ET25 rear) in 22's but i think the tyres on them are wrong in terms of overall variation. I havent a clue what how to calculate them so if you could help that would be great! They have on: Front 285 30 22 & Rear 315 30 22 but im thinking this rear should be 335/25? Am i right in my thinking here? Also with this kind of offset ET20 front/ET25 rear does this work ok without any spacers? im not wanting an aggressive look and want to keep them within the arches on my Msport model X5 Chris |

Less is better. No more than 1% for me.

The less difference in diameter between the front and rear axles, the better. No more than 1% difference.
