Tyre & Rim sizes

projects, Have look at Cooper web site, they show recommended rim widths to suit each size. Hooroo...

thats actually a hard question to ask at work(im in the tyre buisness) WE use a tyre and rim guide if we get stuck i mainly use it for road worthy issuesto make sure a certain tyre can legally fit a rimsorry if that didnt help
looking foward to easter at jamieson

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?
