Help with tyres on 20 inch wheels.

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!

 

Your existing tyres are the wrong width, you should have 255/30R20. If you want a thicker sidewall you will need a smaller wheel in order to keep the tyre circumference correct.

 

Are they really? There doesn't seem to be much of a stretch. This is good news though as the 255 tyres are slightly cheaper. Would you say the 255's are the best fit?

Thank you for the response!

 

I have 265/30 on my factory option 20" wheels

 

255s will give you slightly less sidewall than 265s. My SQ5 runs 255s but the rim's an 8.5J, 265s should be fine on a 9J.

 

I'll probaby stick with the 265's in that case, prefer slightly more sidewall

 

255/265 is the Width of ur Tyre, 30 is the Profile/depth of Wall.. By going 19s u could still Run 265 but have a 40 Profile/depth Tyre. (Sidewall as you call it).
