So I found some decent Yokohama advan apex tires.

I know people with stock supra suspensions even without spacers on stock height can fit 305s in the rear and 275 in front?

Anyone tried it? I can't find 305/35/19 with the 275/35 rear for the tires I want.

I'm guessing it's not the best idea to mix different Tyre types.

IS the 305/30 aspect ratio ok in the rear?

Will they fit well and has anyone slapped on much wider wheels in the rear?

I remember in my 2015 m235i 18 inch wheels they were ugly 225s all around with 40 aspect, so I slapped on 235/35 front I think and 255/30 rear and they were fine.

I think the z4 can handle going to 275/35 front 305/30 rear

Be very very careful with those choices. Use Tire Racks specific measurements as there is no "standard" physical size for a 275 or any other tire. Physical measurements all vary by brand.

This is what a 275 looks like. The 315's in the back a just over a foot wide. The 305 is about 1/2" narrower.



275 Front


Old 315 Rear - Tiles are 12" squares. My new 315's from same manufacturer, NITTO, are wider than the old ones.
