Car: 2008 A4 Quattro 3.0 TDI Avant
Bought the car about 6 months ago, and I need to replace the 2 front tyres at least for my upcoming MOT. I've noticed that its running on 225/40ZR18 92W XL, but on the plate on the inside of the door it states 235/40/18 XL.
If I replace the 2 fronts to the correct spec (235), should I really be changing the rears as well?
What tyres do people recommend? Anything that might reduce the firmness of the ride? Do they need to be XL spec?
