Hi all, I currently have 18" wheels on my B7 A4 with Falken 452 tyres all round, size 235/40 R18. I need to replace both front tyres so am weighing up my options for the following: A) Just replace 2 x front tyres with standard summer tyres. B) Purchase 4 x Winter tyres size 235/40 R18 - which will be on the car until Mar/April, and then purchase the 2 new front summer tyres when I remove the winter tyres. Although 18" winter tyres are pretty pricey! C) Removed. Where can I find the ET number for my current wheels? which are these: Many thanks in advance for your time. Cheers, Dan.
