Hello,

i have ordered 10,5x20" and 9x20" RIAL DAYTONA SPLIT RACE

Dunlop tires 285/30x20" Rear

But the qestion is if it is possible to mount 255/30x20" Front ????


I have had 245/30x20" earlier without problems.


Anyone driving 255/30x20" front ???? Pictures ??

Stock front and rear tires are ~25.7" tall and ~784 rev/mile.

The 255/30's would be 26" tall and 775 rev/mile (1.2% difference)
The 285/30 would be 26.7" tall and 754 rev/mile (3.9% difference from stock and 2.7% difference from the 255/30)

I would assume using this size tires would freak out the traction control. In my E36 anything above 1% would freak the traction control out. I would bet that it would be no different in the E60. The tires are so different in size that the car thinks it is loosing traction.

I would recommend to get the correct size tires if you want your car to drive right.
245/30R20 Front and 295/25R20 Rear is what you should be running.

Here is a nifty little tool to use.
