437M’s with M4 tire sizes - 275/35/19 Rear (on 4 Pot)

[True-Blue]

Thought it was worth a quick update for future reference.

I currently have O.E. 437M’s fitted with standard M4 tire sizes, 255/35/19 & 275/35/19

It seems a number of forum users have these fitted without any rear rubbing issues, but after further testing I’m not sure how :?

Took car out yesterday for a more spirited test, and rear tires definitely rub the arch liner on outside on fast corners and depressions.

My car is a 20i with standard MSport suspension, I’m not sure if the track etc is different on the 35i/35is or possibly if lowering further impacts the camber angle to avoid this rub... but currently can’t see how this tire size works.

In addition, IMHO these tire sizes ‘over-tyre’ a mapped 4 pot turbo, might be justification on a 35i/35is.

I’m going to have new tires fitted this week

Though it was worth a separate post, as easy to get lost in the other wheels/tire threads

One of our chaps up here has a 18i, non MSport with the same wheels/tyres and has rubbing on full lock and elsewhere..in a parallel discussion I think he's headed to the next sizes down that can still on those 9J/10J rims.
