i have oe bbs 14" wheels on my gti and was wondering what is the widest tyre size i can opt for without doing any work to the car. i currently have standard 185 60 14 on thanks Collie.
If the wheels are 6Jx14 i.e 6" wide, then you don't really want anything wider than 195. You can get Toyo Proxy T1-S in a 195/55/14 fitment which will fit. Toyo also do a 195/45/15 if you want a much lower profile tyre.
I don't like 195 on 6 inch rims, I find them sketchy. 185s are fine, depends if you want handly or looks. I went from 185 on 15x6J to 195 and swapped them back within a week
I've got a set of 195/50/15's on a 6J rim, and a set of 195/55/14's also on a 6J rim. The tracking was a little out when I switched from a 185 to 195 tyre, but once the tracking got realigned they worked and gripped really well. (Toyo's T1-S's)
I put 195/55/14 on a standard 14in steelie (which are either 6J or 6.5J, I can't remember) without any problems. They were Bridgestone Potenzas, the best tyres I have ever used.
I'd agree on the Potenzas, I bought a set when they first came out on the recommendation of a mate who's a tyre specialist and haven't looked back
