is it worth it on 19" rims? there isn't much side-wall to give anyway especially when you factor in the high pressures.
may have a chance to downsize to 18's to someone wanting the better looking wheels
i assume the rims are the same for rft's or not so adding some foam and a pump to the car shouldn't effect anything???
no real difference in cost here in 18's or 19's about £630 fitted ($1000)
ps we have 17" rft's on our 3 m-sport and don't mind it so much
pps what are the correct tyre sizes for 18's?
Had 18" PSS on my 335i. The ride was a lot less harsh than the stock RFTs. You can replace RFTs with regular tires and reuse the same rims.
The 18" sizes are 225/40 front and 255/35 rear.
