Was looking in my logbook, and the last service says the tyres were too big for the wheels on the rear. I have e90 m3 wheels they are 19 x 9 and the tyres are 265/35/r19, is this the right size? If not what is the correct tyre size? I get a whole lot of running in the rears at the moment!! Maybe a 255/30??

Yeah sorry, auto correct I meant rubbing. On the front iv got 245/35/19. I was thinking 255 / 30 will be a nice fit, I think 245 will be a bit of a stretch. Oh and it's rubbing on the inside of the guard and maybe looks like its rubbing a touch on the rear bumper.

OEM E90 wheel specs are 19x8.5 ET29, 19x9.5 ET23; so they're not OEM if they're +45 offset.
You should have no issues with 19x9 ET45 and a 255.

My setup is:
18x8 ET35 225/40
18x9 ET32 245/35 (rolled guards)

EDIT:
Offset on the wheels are 45. I'm thinking about new wheels, what should the offset be on a new set if I buy something?
Offset depends on wheel width, normal staggered fitment that most people with aftermarket wheels run on an E46 is 8.5" Front and 9.5" rear, with offsets around 35 and 40-45 respectively. Just depends how aggressive you want to go.

Cheers for the info man, looks like I'll have to look into new rear tyres then

What size are you running on the front? I would run a 255/30.
You should also work out where you're rubbing, most of my rubbing was coming from the clip where the fender meets the rear bumper which won't necessarily be cured by a skinnier tyre. Tape up your fender with masking tape, go for a drive and see where the rub marks are.
