Since I'm sure that at some point somebody will come looking for this...

All models use a 5 x 114.3 mm (5 x 4.5") hub bolt pattern. Offsets in the range of 35 - 50 mm should fit - you don't normally see wide wheels with high offsets that result in big backspacing. Hopefully someone can find out the center bore of the stock wheels...


Sport/Touring:

Stock tire - P225/65R17 100H
Stock wheel - 17 x 7J


Safe +0 tire fitments (all listed sizes will mount on a 7" wide wheel):

215/70R17
235/60R17
235/65R17
255/60R17


Safe +1 tire fitments and suitable wheel width for tire:

225/60R18 - 6.0-8.0"
235/55R18 - 6.5-8.5"
235/60R18 - 6.5-8.5"

Note 1: Pirelli doesn't seem to think that the rest of the tire industry's standards for suitable wheel mounting width apply to them. There are quite a few Pirelli tires that have oddball width ranges compared to other tires of that size. I've noted where I ran across these in compiling this list, and marked sizes for which Pirelli has at least one offering with a different recommended mounting width. There are undoubtedly more, but this is just what I've run across so far.

Note 2: These sizes are somewhat questionable, but Continental's Tire Selector indicates that they're suitable fitments for a CX-5. They certainly meet the load rating requirement for the vehicle, but I'd keep an eye out for rubbing if anybody wants to try them.


As for bigger sizes - If anybody can find a 21" wheel that will fit the CX-5, I'll be happy to compile suitable tire sizes. Until that happens, I'm not bothering with it. Anybody who wants to put 22" wheels on their CX-5 can do their own homework - the load ratings on the tires are marginal at best, and the wheels are ridiculously heavy. I strongly recommend against it.

For the 2015 CX 5 AWD Touring on stock 17's will 235/55ZR17 fit without rubbing or clearance issues? The Michelin Pilot Sport AS 3 or Pirelli STR are my preferred choices but I'm having trouble finding sizes for my cx-5. The vehicle is used in Southern California commuting plus light gravel roads and light snow on ski trips. Thanks.
