DenisMcG Posted October 14, 2014 Report Share Posted October 14, 2014 (edited) I have an almost new set of Michelin X-Ice snow tires that I used on my Subaru last year. I am just wondering if they will physically fit on the C-Max without rubbing on anything. I am aware that the speedometer will be out. How much wiggle room do the 215/60/16 tires allow? Thanks Edited November 24, 2014 by DenisMcG Quote Link to comment Share on other sites More sharing options...

fbov Posted October 15, 2014 Report Share Posted October 15, 2014 (edited) I've got 215/60-16's, which are almost a dead-on replacement, speedo-wise (>1%), for a -1 size. You'll have more like -4% error; the added ~1/2 inch tire radius is fine. You will need new rims, unless Ford and Subaru use the same bolt pattern, offset and center hole diameter. Here are the one's I got (select "basic steel sheels"), stamped FORD. Have fun,Frank Edited October 15, 2014 by fbov Quote Link to comment Share on other sites More sharing options...
Marc Smith Posted October 15, 2014 Report Share Posted October 15, 2014 the cmax is 225 /50 17 which means the contact patch is 225mm wide and the sidewall is 50% of that or 112mm so your overall hieght 112 + 112 + 432 656 mm your snow tires are 215 mm wide with a 129mm sidewall so 129 + 129 + 406 = 664 which means you snow tire hieght is 8mm taller.. show that your speed will be 3.8 mph faster @ 65pmh obob 1 Quote Link to comment Share on other sites More sharing options...
fbov Posted October 15, 2014 Report Share Posted October 15, 2014 Marc,You can't trust side wall dimensions as they're just nominal values, and even if accurate, you're still comparing unladen diameters. To get an accurate result, compare rev/mile. Full spec sheets are one reason I patronize Tire Rack. However, the OP is confusing us; the thread title is 215/65 while his post talks about 215/60's. I replied based on the title, as that's the one with a difference... of 2.8 mph at 65 mph based on rev/mile. Have fun,Frank. Quote Link to comment Share on other sites More sharing options...
Marc Smith Posted October 15, 2014 Report Share Posted October 15, 2014 tires are like shoes/clothing when it comes to sizes...Tire rack doesn't exactly say how they compute the "revs per mile"? I got my mph data from http://tire-size-conversion.com/speedometer-calibration/ and I made a mistake (brain fart, end of the day) at 65 mph indicated the 215 65 16 is showing an actual speed of 67.8 and the 215 60 16 is an actual speed of 65.7 which correlates to your 2.8 mph... obob 1 Quote Link to comment Share on other sites More sharing options...
DenisMcG Posted October 16, 2014 Author Report Share Posted October 16, 2014 Thanks everyone for the info. I have 215/65/16 tires that I will remove from the Subaru rims and then buy new 16" rims for the C-Max. The reason I asked about the 215/60/16 is simply because I know that some have fit those to their cars and I was interested in knowing if there was enough extra space for the taller tires that I have. I am fully aware that the rolling radius is different and am not concerned with the fact that the speedometer will be incorrect. I just need to know if my tires will fit. If the fit is too tight, then I will sell the the 65s and buy some 60s. Thanks again, Quote Link to comment Share on other sites More sharing options...
fbov Posted October 16, 2014 Report Share Posted October 16, 2014 tires are like shoes/clothing when it comes to sizes...Tire rack doesn't exactly say how they compute the "revs per mile"? ...Exactly why I use spec sheets... I once had Pirelli P7 175/50-13s, and they were as wide as 205/60's... but not as tall. Great gearing for autocross. I doubt Tire Rack computes anything, as if they did, all tires would have a rev/mile spec. It makes sense they'd post manufacturer's specs, so Michelins have a rev/mile spec, while Pirelli's don't. Fuzion does but not Kumho, in a quick survey of C-Max tires. Neat calculator... And DenisMcG, too bad you have snows... Laurel's offering a heck of a deal!

Marc Smith Posted October 16, 2014 Report Share Posted October 16, 2014 Do you autocross??? about the most fun you can have with your clothes still on...:) Quote Link to comment Share on other sites More sharing options...
fbov Posted October 16, 2014 Report Share Posted October 16, 2014 In my youth... in the 80's I thought I'd never lose interest, but the 90's proved that my avocations have a half-life. Thankfully, my employment has proven otherwise; 35 years at the same company, or I might not have had the luxury of seeing the pattern in my personal interests. Are you in SCCA or do you do marque club events? Northern VA isn't far from Harrisburgh, where our Divisional Solo II Championships were held in my day.

Marc Smith Posted October 16, 2014 Report Share Posted October 16, 2014 I had a 94 impala SS that I autocrossed in florida upgraded sway bars, springs, cams, 5pt harness, gumball tires, a well built trans... Also did some track days at Sebring, and when I moved up to DC I had it for a while and took it Summitt point and also Autocrossed. Also drove a beater CRX for autcrossing. not nearly as fun to slog around the course as a 2 ton boat. I ended up with a spare transmission and would do transmission rebuilds on my work bench and do 2-4 swaps a year in my garage... Got to be a bit expensive, tires, and such...Wife loved the car, but it wasn't a good city driver... Quote Link to comment Share on other sites More sharing options...
DenisMcG Posted November 24, 2014 Author Report Share Posted November 24, 2014 Just a quick update. I had two sets of winter tires and decided to go with 225/60/16 instead of the 215/65/16. The 225s fit just fine with no rubbing whatsoever. I realize the speedo will be off by approx 3%, but I can live with that. I put the 215s on my Subaru.
