[M340Why]

I have an M340i with the stock 19"225/40 run-flats. Besides upgrading to 20" wheels has anyone done anything to help with the wheel gap? I've considered lowering springs but not sure what effect that would have on ride quality. Maybe a thicker tire?

Do you have a square setup or staggered?

Someone posted a while back of their 235/40-19s (front) and 265/35-19s (rear) and it looked pretty good. Closed up the gap slightly if you don't want to lower.

You can also install some hub centric spacers and push the wheels out slightly. I've seen anywhere from 10-15mm spacers on some of the cars here.

I would look into the Dinan Springs and bumpstops - I'm running them and very pleased with the overall ride quality and height. Here is a pic of my car with dinan springs with oem wheels (and spacers)

Hope this helps

I'll definitely look into staggering/spacers, thanks. I have the square setup with the Pirellis. Thinking of jumping to the Pilot Sports but not sure if they'd make a significant difference...

zero and that's with a 15mm on the front and a 13mm on the rear

Another similar perspective. Dinan springs and 10mm spacers. Factory staggered setup: 225/40 and 255/35-19s.
