Tyre size advice.

[Dave1971]

I’m currently looking at tyres as my rears will need replacing soon, they are the standard z4 sizing of 255/30/19. When I bought the car it had Michelin super sport on the front and Falken 452 on the rear. When I change the rears I’d prefer to keep the same brand of tyre all round, I know it’s not a problem to run different brands front to rear but I’d prefer not to.

The main issue is tyre availability, if i change from 255/30/19 to 255/35/19 there is so much more choice available at the moment. I know some people have gone up a little on the sidewall for comfort reasons so is anyone else running that profile?

I have b12 suspension setup if that makes any difference.

235 + 265 are no issue on OE wheels as well as upscaling profile by one (35 to 40 and 30 to 35)

Depending on your rim sizes you could look at 235/35 19 265/30 19 as well

255/35 19 MAY under certain circumstances cause DSC related issues like failing to detect punctures…

255/30/19 is the best choice in my opinion

Interested to hear why you would think this ?

Mine came on the 326's which had MPS4S all round - the rears are 255/35/19 and are due for replacing but the fronts (225/35/19) are still fine .
I've had no issues at all and when I took the wheels off to check them none were cracked or had been welded - suffice to say I will be ordering the same size for replacement hopefully later this

I know 255/30/19 is the size the car came with but after over a decade of rim cracking and unnecessary tramlining most of the E9x community have adopted 255/35/19 as a healthier alternative for the rears - more compliant and protects the rims more and they fit without issue. I haven't put a 30 profile on my rears for a very long time now - across E46, E92, and now two E85's.

Just my reflections, obvs.

Forgot to add that I'm running 235/35 F and 255/35 R on my style 367s.
