Tyre Sizing 19" Wheels
Discussion
Evening,
I am after some advice regarding tyre compatibility please.
I have just purchased a Z4 Coupe and the seller had 2 different sets of wheels, i didn't take both sets and have purchased the car with winter tyres on.
Initially I thought i'd just swap tyres, but given that a reasonable set of wheels can be had for not a huge amount of money and we seem to be enjoying ever more mercurial weather in this country, the luxury of being able to swap wheels at home is more appealing.
The winter tyres are on an 18" rim and i quite fancy going for some CSL style wheels for summer use. The seller had summer tyres on 19" rims (see sizes below) and experienced no rubbing, the car is lowered 20mm on eibach springs.
Given the sizes i state below, would my planned wheels rub if his old ones didn't? As far as i can see he was running a wider rear wheel with a more aggressive offset, so if anything my planned set up should be less prone to rubbing, but i didn't know if this was the case. The 'tyre man' has suggested 255/30 on the rear but this limits availability on the tyres - to either cheap or pricey!
sizes:
Existing 19"x8.5" et38 (tyre 235/35/19) front and 19"x9.5" et45 (tyre 265/30/19) rear
Planned 19" x 8" et34 (tyre 225/35/19) front and 19" x 9" et37 Deep concave (tyre 265/30/19) rear
Many thanks for any assistance.
