mark1 0 Posted May 15, 2008 Hi All Has anyone run anything like the following on a late vr, and was there any clearance issues? BBS RX - 17 * 7.5 with 225/45 rubber & et35 (I think this is the et anyway). I have done the search which is great for 16's but I could not find anything conclussive re. 17's with 225 rubber. Car is stnd ride height but may go for a lowering of 35mm in the future. Thanks for any help, Mark Quote Share this post Link to post Share on other sites
dukest 0 Posted May 15, 2008 hi there.. your overall wheel/tyre diameter is 2 inches larger with that set up, it would look quite strange i think and your speedo would be 8% out. also, you might well get clearance issues with wider tires like that once you go lower. normally people go for 205/40/17 to maintain similar dimensions and speedo accuracy, if you dont want the stretch maybe go for 215/40 to be 3% out or even /35 for info from here http://www.miata.net/garage/tirecalcold.html cheers Quote Share this post Link to post Share on other sites
mark1 0 Posted May 15, 2008 Top man - thanks for the info & link. Looks like 225/45 is a no in that case. Cheers, Mark :thumbleft: Quote Share this post Link to post Share on other sites
