AndreyLegacy Posted March 31, 2006 Share Posted March 31, 2006 Hi, I have a SpecB in Russia, and getting good Winter tyres in 215/45R17 is a bit of a prob. I bought the 205/50R17 - they are good, but I'd prefer the car ground clearance to be a bit higher. So question is - would the 225/50R17 fit in? I did not bother to try, but did anyone ever tried it?

IwannaSportSedan Posted March 31, 2006 Share Posted March 31, 2006 What is the size of the original tire? 215/45-18? (that is what the US spec B uses...) The 225/50-17 you mention is VERY close to that. Using a tire calculator, it estimated 7 Revolutions fewer per mile, and the 17" would have roughly 3/10ths of an inch more diameter (.7 inches more circumference.) http://www.miata.net/garage/tirecalc.html I would think that would be an excellent size for winter tires, with a taller more flexible sidewall for snow and ice grip, and better impact protection, and no sacrifice in ride height, and negligible speedometer error.

SC GT Posted April 1, 2006 Share Posted April 1, 2006 I'm currently running 225/45/18s on 18 X 7.5 rims with a +50 offset, GT Bilstein struts, and Wangan springs. The diameter of my tires is .1" bigger than yours, and I get no rubbing. You should be fine. Link to comment Share on other sites More sharing options...
AndreyLegacy Posted April 1, 2006 Author Share Posted April 1, 2006 I was worried that it is both a bit higher and a bit wider. Link to comment Share on other sites More sharing options...

edmundu Posted April 7, 2006 Share Posted April 7, 2006 What about speedo correction? I heard the SSM can reprogram for either the SpecB 18" or the LGT 17", is that true? Link to comment Share on other sites More sharing options...
MacLGT-B Posted April 7, 2006 Share Posted April 7, 2006 So question is - would the 225/50R17 fit in? I would love to know as well. Link to comment Share on other sites More sharing options...
