Tyre size difference

M5 TT · 02-12-2021, 05:58 AM

Sorry to be boring and bring this up.

I have searched all 18 pages and done some searching and cant find the answer.

My fronts are good but rears need changing. I am tempted to go with 295 on the rear but that puts the front to rear ratio up to 1.96% (stock is (0.99)

Anyone running (long term) that sort of ratio?

Slightly off topic, anyone running 255 50 19s?

M5 TT · 02-17-2021, 06:48 AM

Anyone tried

275/35/20
315/30/20

Only 0.7% difference RR.

Will 315 fit without rubbing

Im very curious to hear why there are not more M5's on here with at least 305's on the rear? I assumed this car would accommodate the clearance needed to achieve this. Most pictures I see tend to be 295's

I had 305s ps4s but then switched to sport cup 2 connects and they don't make 305 so had to go with 295/35 but oddly enough sport cup 2 is a little bit wider than 4s 305.

I guess unless you are launching the car it has enough grip? I have only launched 4 times (not really interested) it lights up the rears in cold conditions other than that it puts the power down.

I was going to fit 305 ( found out 315 will fit) but can’t be bothered changing the fronts to bigger size as they are pretty new.

My rears are knackered will prob just fit 285 again.

I read people put 295 on and leave the fronts stock with no issues, maybe that’s why? Easy? Not sure.
