Alternate Tire Size for Your Mazda CX-7

Thursday, August 2, 2012 by Hunter Leffel

Starting in 2010, Mazda started to offer the CX-7 with a 17" wheel option equipped with a 215/70R17 tire. As we sometimes see, this is the only vehicle that uses this size. This of course means replacement options can be a challenge. When dealing with a tire size that fits just one vehicle, tire companies (other than the Original Equipment supplier) are hard pressed to justify the investment of entering the market. Typically, the Original Equipment tire doesn't receive high marks in the feedback collected and this leaves customers shopping for replacement options in a bit of a pinch. Fortunately, Tire Rack has an alternate size recommendation of 235/65R17 that offers some very good choices.

The Destination LE2 is the latest entry from Firestone in the Highway All-Season category. Check out my previous blog post "The All-New Firestone Destination LE2" to see how it may be a good option for your vehicle.

Bridgestone's Dueler H/L Alenza is a perennial favorite amongst our customers. It's currently sitting in fourth place in our Tire Survey Results after 21 million miles reported. With this many miles reported, customers like the tire throughout its life, even when it's close to being worn out.

Another highly rated and long-term favorite is the General Grabber HTS. The tire offers a good ride, low noise, responsiveness and great wet traction.

By going to this optional size, it opens up all sorts of great solutions for your Mazda CX-7.

Monday, April 15, 2013 by Hunter:
Hi Michael,
The alternize size is about 3/4" wider and .1" taller than the original size

Just changed over to Firestone Destination L2 235/65/17. Best desicion ever. Not only does the car drive better, it also looks better. They fit perfect and no rubbing anywhere.

What about winter tires. Should I go for 235s as well?
Tuesday, September 17, 2013 by Hunter:
For winter I would stay with the 215. Bridgestone Blizzak DMV1 is offered in that size. It is a great winter tire.
Tuesday, October 1, 2013 by S Johnston:
Would a P225 be an ok exchange for the Mazda CX7 that currently has a P215.
Wednesday, October 2, 2013 by Hunter:
Hi S,
Sure you can use a 225/65R17.

I am trying to replace with GOODYEAR 235/55/17 for Mazda CX7, 2010 model P215/70/R17. Is this going to be fine?
Wednesday, October 9, 2013 by Hunter:
Hi Hash,
The two sizes you are comparing are quite a bit different. I do not think you will be able to make that substition
Friday, October 25, 2013 by Anna Marie:
I am trying to find replacement tires for my Mazda CX7, 2010 model P215/70R17, are the 235/65R17 the best option - want to make sure there is no rubbing.
Friday, October 25, 2013 by Hunter:
Hi Anna Marie,
The 235/65R17 will fit without rubbing
Sunday, November 17, 2013 by jasmine:
I am trying the best replacement for my Mazda CX-7, 2010. Which is better? 225 65R17 or 235 65R17? What will be the difference?
Tuesday, November 19, 2013 by Hunter:
Hi Jasmine,
235/65R17 is the alternate size we recommend
Friday, January 10, 2014 by Lulu:
I have a 2012 Mazda CX7 Sport. What are some good alternate sizes for this one?
Tuesday, January 14, 2014 by Hunter:
hi Lulu,
The 2012 is the same as the 2010 mentioned int he article.
Tuesday, February 18, 2014 by Matthew:
Are there any adverse effects from using this alternate size tire.
Friday, February 28, 2014 by Clive:
Awesome information. Having got high quotes for the one available tire for the CX7, its good to know we can use an alternate, more common size.
Thanks guys!!
Monday, May 12, 2014 by Ivan:

Can you please explain why you recommend 235/65/17 vs 225/65/17? I own 2010 Mazda CX-7 and the stock tires are 215/70/17 but there is literally no options except for the OEM Bridgestone.
Wednesday, May 14, 2014 by hunter:
Hi Ivan,
You can us 225/65R17 as well
Sunday, May 18, 2014 by melanie:
I need to only replace two tires Is it okay to have two 225/65/17 and two 215/70/17
Monday, May 19, 2014 by Vicki:
when subbing out the 215/70R17 for 235/65/17, do I have to replace all four tires? I only need to back tires at this time.
Tuesday, May 20, 2014 by hunter:
Hi Vickie and Melanie
You should not run different sizes
Monday, June 9, 2014 by Katie:
If I want to use the alternate size tire, do I have to replace all four tires? Or can I just buy two tires and leave two 215/70R17 on my car?
Monday, June 9, 2014 by hunter:
Hi Katie,
you should not run different sizes
Tuesday, June 17, 2014 by Felicia:
Thank you for all your advice Hunter! This article has been a lifesaver!!!
Monday, August 11, 2014 by Lidi:
What would you recommend more 235 65 17 or 225 65 17 and why?
Monday, August 11, 2014 by hunter:
Hi Lidi,
Either one of those will work. The 225 is shorter than the original size and the 235 is taller
Sunday, September 14, 2014 by Ed:
I'm confused... the number 235 in the size 235 65 17 refers to the width of the tire, so I have a hard time seeing how a 235mm wide tire will fit on the stock CX-7 wheel that was narrower (sized for a 215mm wide tire). Please explain how you squeeze in a 235 mm wide tire onto a 215 mm wide rim.
Monday, September 15, 2014 by hunter:
Hi Ed,
Looking at the engineered specifications for the two sizes, 235/65R17 mount on wheels between 6.5" and 8.5" The 215/70R17 have a range from 6.5" to 7.5" This is straight from the tire manufacturers. It can be verified on both Tire Rack and the manufacturers' sites. We show the original wheel on the Cx-7 is 7" wide.
Tuesday, September 23, 2014 by Ed:
Thanks Hunter. I get it now. But why do you feel 235/65/R17 is preferred over 225/65/R17? Isn't the 225 closer to the original stock 215 than 235? I know you said before that 225 can be used as well but curious why you prefer 235.
Monday, September 29, 2014 by keith:
will 215/65r17 work as well
Thursday, October 2, 2014 by Adam:
I also have Mazda cx-7 2010 with stock size 215/70-17. If i get different size tires, do I have to get different wheels as well? Or as long as the 17' is the same it will all fit?
Thursday, October 2, 2014 by hunter:
Hi Adam,
Different size can have different rim width specs. Youwould need to get your current wheel width and verify against the specs for the tire you want you use. Size recommended in the article will work with the original wheels
Sunday, October 26, 2014 by Liz:
Can 2011 Mazda CX7 use the same alternatives (225/65r17 and 235/65r17) to replace the tires?
Sunday, October 26, 2014 by jennifer:
I have a 2007 Mazda 3. Will tires off of a Mazda CX 7 fit my car? It currently has 205/55/r15
Tuesday, October 28, 2014 by hunter:
Hi Jennifer,
205/55R15 looks to be too short for the Mazda 3. So I wouldn't recommend that.
Tuesday, October 28, 2014 by hunter:
hi Liz,
yes same alternate sizes for the 2011
Sunday, November 9, 2014 by Liz:
By using either 225 or 235 to replace 215 for cx7, will the bigger tires cost more gas mileage? Any other downfall that I need be aware of?
Tuesday, November 11, 2014 by Pierre-Luc Bélanger:
Can I put 16 inch wheel with 235/70/16 tire look like the same size then my wheel now 255/55/18 and I got this set for really cheap
Wednesday, November 12, 2014 by hunter:
Hi Liz,
There will be more rubber contacting the road. This could lead to some minimal losses in fuel economy.
Wednesday, November 12, 2014 by hunter:
Sorry you cannot put an 18: tire onto a 16" wheel.
Thursday, November 13, 2014 by Rosetta:
I have a Mazda 2010 CX7 and about to purchase the 4 tires recommended here as replacements for the R215 tires... I see different speed ratings on them....what difference if any does that make?...which should I get the oe with Speed rating of H or T?...Thanks!
Friday, November 14, 2014 by ray:
could I go with 235/70/R16 if I changed my rims?
Friday, November 14, 2014 by hunter:
The T rated will give a little smoother ride. The H, a bit more responsiveness
Friday, November 14, 2014 by hunter:
Hi Ray,
I think 235/70 will be too tall to fit
Wednesday, November 19, 2014 by Pete:
Doesn't using 225/65r17 and 235/65r17 instead of a 215/70r17 put you off on odometer or spedometer?
Wednesday, November 19, 2014 by Nick:
I gather for 2011 CX-7
215/70/R17 or
215/65/R17 for Winter
235/65/R17 for All Seasons
Would be the good substitute ?
Thursday, November 20, 2014 by hunter:
Hi Nick,
We recommend 225/65R17 instead of 215/65R17
Saturday, November 22, 2014 by Dave:
Has anyone who switched to 235/65R17's for their Mazda CX7 had a problem with the tire rubbing?
Saturday, November 29, 2014 by Bruce:
Is the continental cross conti with eco plus LX20 a good tire 235 65 17 mazda
Monday, December 1, 2014 by hunter:
Hi Bruce,
That is a great tire. Currently ranked #1 by people using the tire.
Saturday, December 6, 2014 by David:
wondering if the 235/65R17 will fit on the same rim as the 215/70R17, As the 235 is wider?
Tuesday, December 9, 2014 by hunter:
Hi David,
Those two sizes will work with the factory wheel
Thursday, December 11, 2014 by Nick:
I appreciate your time and dedication. Happy Holidays

My wife has 2012 Masada cx7 touring. She likes the goodyear ultra grip winter tires. Will the 235/65/17 fit? Thanks
Monday, December 15, 2014 by hunter:
Hi Chris,
Yes the 235/65R17 is the alternate recommended size.
Tuesday, December 23, 2014 by Sandy:
I have a 2012 CX7, tire size 215/70R/17. I have a set of studded tires size 225/60R/16. If I bought 16" rims could I put these studded tires and rims on my Mazda CX7?
Saturday, December 27, 2014 by Judy:
Has any one ever put a 235 65 17 Yokohama geolander at/s on their mazda cx7, which came originally with the 215 70 17?
Monday, December 29, 2014 by hunter:
Hi Sandy,
The 225/60R16 is not going to work on the CX7.It is too short.
Monday, December 29, 2014 by hunter:
Hi Judy,
235/65R17 will fit on the CX-7
Tuesday, January 6, 2015 by Suzanne:
i have a 2011 mazda cx7 and am literally searching high and low for the 215/70R17. the only place that i was told that has them is the mazda dealer for an arm and a leg and that is just for the tire alone without installation. I am a bit nervous to get a replacement size. which option is better for the 2011 SV - 235/65R17 or the 225/65 R17. Also, how can they possibly fit being that it is a different size. I am confused. Please advise and explain. Thanks so much for you time.
Wednesday, January 7, 2015 by hunter:
Hi Suzanne,
We have the original tire in stock and available to ship.
Friday, March 20, 2015 by Will:
Good post, thanks. Thinking that the key for me will be finding the tire I like based on reviews/price in the 235 or 225/65 R17 size that comes closest to original OD and RPM specs. This should cause the least chance of speedometer being off correct?
Thinking that the Continental TrueContact(Standard Touring All-Season) 235/65 R17 would be one I'd consider. Original Bridgestone is 28.9 overall diameter, while the Continental is 29.0.
Do you think this would cause more than a 1% difference in speedo reading? Also, thinking that the slightly larger diameter might offset MPG difference that might be induced by wider tread.
Saturday, March 21, 2015 by Ruben:
Can I use 245 70 R17 for mazda cx7?
Monday, March 23, 2015 by hunter:
Hi Ruben,
No. That size is too short.
Monday, March 23, 2015 by hunter:
Hi Will,
I would not expect there to be a detectable difference with a diameter difference of .1 inches.
