Wider tyres on the same wheel?
 

I used to know this but like homer Simpson new stuff has shoved the old out.

I run standard 17" wheels with 225/ 55. When I had to get a new set a little voice in my head was saying that the wheels have to be 8-8.5J's and surely a 235 or 245/50 would fit safely. I stuck with caution and kept to standard. This time.

What's the fattest rubber i can fit safely then my homies. Word. Out. Innit?
