[QUOTE="Maniac, post: 621630, member: 20491"] hello kawan-kawan. i wondered about this "j" question too when first coming across it a while ago. here's an excerpt of an article i found which gave me a satisfying answer: [img]http://www.carbibles.com/images/beadprofile.gif[/img] it is [I]the letter that typically sits between the rim width and diameter figures stamped on the wheel, and indicates the physical shape of the wheel where the tyre bead meets it.[/I] full article here, which a heck of a lot of other good information. [url]http://www.carbibles.com/tyre_bible_pg4.html[/url] key point to note - make sure your rims & tyres have the same profile stamp, otherwise they wont fit! :) c-square. yup, a bigger tyre width will bulge out of your rims. check fitment to ensure that you are first able to put them onto the rims. if you can, you'll have added protection from kerbing your alloys :) [/QUOTE]
