Hello! So it's looking like my S5 will be needing some new tyres soon. I'm not very clued up on tyres and I am currently running the optional 20" alloys with an offset 0f 29 and a rim width of 9J, the tyres on the car are 265/30/ZR20. My question is will I be able to run bigger tyres on the car because I would like a thicker sidewall ideally, I've considered swapping to 19's but the 20's are very highly regarded and they do look very smart. Going to go for pilot sport 4 S or Goodyear. If anyone could let me know what size tyres I could go for which would fit that would be appreciated! Thanks!
