Ok so I know this will not be to everyones taste, and was a brave move. 17" CH on some Uniroyal winters I had off my old A4. I do the Cat'n' Fiddle to work everyday, and those that have driven it will understand my madness. Wanted more tyre for the incoming snow, and wanted an excuse to get the Rotors off to clean/wax/seal ready for Spring. The Uniroyals grip like poo to a blanket too. Already been given a good shakedown on the slippy roads and allow for some 0-60 without the traction control light on. Not alot of space inbetween the brakes and wheel, was nervous having them fitted. Cost, only a few hundred pounds more than what 18" snow tyres would have cost, just hope it snows like last year now!!
