How do you determine what width tyre can go on what rim? e.g. If the standard tyre/rim for a Grand Vitara is 235/60 on a 7JJx16, can I go 225/70 or 225/75( assuming space )? I have looked up Hankook's and seen for a 225/75R16 they show a 6.0 rim size yet I have seen on an earlier model Vitara, Suzuki fitted 215/65 R16 on a 6.5Jx16. Is there some basic guideline?

Projects, all tyre companies publish a tyre to rim chart for fitment sizing. Check this first. Then take note of what others are running for the size you like and compare what looks good for you.By wary that not all tread widths are the same width for the same section width, so you may like the look of one brand of tyre on a 7" rim, where another brand may seem too skinny. Witness the Cooper 255/85x16 which has the exact same tread width as the 235/85x16 mudder, but because the former is a taller tyre, it looks to be narower on the rim.

Projects, can't answer your question but am going through the same dilemma with my Suzuki GV. I would like to go 225/70/16 but this is about 36mm larger then standard and therefore I am assuming illegal. Have you looked into this matter or even with your insurance company?
