Hey Guys, I'm new to this and was wondering if anyone could help me out with some questions. I have a 2013 C250 sport sedan and was looking into purchasing some O.Z. Ultraleggera wheels 18x8 45mm offset all around and was wondering if I would run into any problems running 235/40/18 (front) and 245/40/18 (rear). Any input would be greatly appreciated.

You should have 225 front and 255 rear and the rear wheels should be bigger than the front.

Right so could I get away with running a slightly wider 235/40/18 in the front and 255/35/18 in the rear with no rubbing or any issues?

Probably it will be fine, but I think you should stick to the recommended tires sizes by Mercedes, if possible.

My previous set (fronts) were 235/40/18 on 18x8.5+45 wheels. No rub what so ever. I did however go back to 225/40/18 to get back into spec.

235 in front should be fine if you have std offset wheels. C63s run 235s in front as standard

What did you run in the rear? According to tire rack it's recommending 255/35/18.

@OP, my 2013, C250 came with staggered 18" AMG wheels when bought new in 2012. The car has only 15k+ miles on it and still running on original tires.
See post# 9 here for reference.

What tire size were you running in the rear? Also do you recall what the width of the rim was?

When i had my 2014 c250 i ran the oem c63 amg wheels 18x8 et45 front with 235/40/zr18 michelin super sport and 18x9 et54 with 265/35/zr18 michelin super sport rear. no rubbing. perfect fit. same od front and back. if you didnt want these sizes go down to a 225 front and 255 rear.
