My Ride: 2005 525d SE Mystic Blue
Default

Looking for some advice,I have a set of 6er Style 121 wheels on my 525d with the original 245/40/19 and 275/35/19 RFT tyres. The fronts need replacing, and I want to start moving to non-RFT tyres (Falken 452's most likely).

My question is, can the 121 style wheels work with non-RFT's? I'm fairly sure it's not a problem, but I've never heard of anyone using 121's with non-RFT's.

Secondly I'd like to move back to the correct tyre diameters for the 5er, and put 245/35/19's on the front, but I'll still have 275/35/19's on the back. Is having different diameters front and back likely to cause problems? I'm worried I'll end up with constant DTC kicking end due to different rolling diameters.

Thanks very much for your help!!

Sure you can put non-run flat tires on them!
I think you should have the same overall diameter tires front and back.
