Correct tyre size?

[Imzy]

Hi Folks,

My C63 w204 is currently on 19” wheels with 255/30 r19 front tyres and 275/30 r19 rear tyres.

I have purchased new rear tyres which are 265/30 r19 PS4s’s as I felt the rears were rubbing on bumps with passengers at the back with the 275’s. I’m sure I should be running 245/35 at the front but will it be ok to run the 255/30 front tyres for the time being until I’m ready to change the front?

Thanks

The main issue will be the rolling radius. Should be close front to rear.
Check on the commonly available tyre geometry web sites.

Checked already . I know the correct standard tyre size but posted on here to hear if any one else may have experience with different tyres sizes .

Alloy Wheels Direct don't list an MB 19" wheel but a 9.5 J Brabus rear wheel is listed with 265/30/19 tyre and front 8.5 J with 235/35/19 tyre.
No ET is listed for the wheels.
