^ This is correct. The sidewall aspect ratio or "35" number is often mistaken to be a fixed value. This makes tire sizes just a little more confusing, especially when trying to find wider tires that maintain the correct OEM rolling diameter.
The M2 has somewhat limited clearance in the front fender wells, so they are sensitive to using increased rolling diameters, and you'll experience the rubbing described in the OP. As mentioned, sometimes it goes away on its own after a few hundred miles, but not always. It really depends on how much larger than stock the tires are.
OEM rolling diameters:
Front 245/35-19 - 25.8"
Rear 265/35-19 - 26.3"
Performance Street/Track tire size rolling diameters that we run on our M2C-specific wheels:
Front 265/30-19 - 25.3"
Rear 285/30-19 - 25.7"

Which means for those like me who primarily use RS4's or RE-71R tires;
Hankook doesn't make a 30 series RS4 which fits the front and the 275 35 series tire as pointed out by ZM2 is too tall.
Which leaves the RE-71R.
The rear is fine you can go 285/35 or 305/30 (the 305 is actually shorter, not that it matters back there)
The front... 255 or 265 and only 35 series for either. Those on stock wheels can do 255/285 and it will probably work out great.
I got the EC7's for more meat and the 255 are too stretched on the 9.5 up front so I will go 265 and to hell with the fender liner.
Hopefully more tire manufacturers will begin throwing the 19 crowd a bone. It's amazing I experience this on both ends of the spectrum with the E30 15" hardly any tire choices in the sizes we want and 15x9's are unobtanium or not ready etc etc. but I digress.
(first image is RS4 sizes, second is RE-71R) |
Are you running a square set of EC-7 or a wider tire in the rear?
