Mazda CX-7 Tires and Wheels

    I did replace two and had a rotation. I kept the other used one since it still has 7/32 of depth. Incase I get flat again it's better for me to have that use the spare, mounted rather than the thin trunk original tire. That is if I get a flat as closer thread depth as my used stoked tire. It also cuts the 50mph limit on the stock spare with the wider used tire. Gives me some time to save up for two more incase.
  • how important is it to keep all 4 tires with the same brand? i replaced the fronts 3 months ago, and now i need to do the rear.

  • Very important to have all the same tires. It is ok to mix 2 and 2 but you always want the same tires on each axle. I would never put 3 one brand and 1 another optimal handling and traction are obtained with all 4 the same.
  • I just traded down from a 2008 CX-9 to a 2010 CX-7. The first thing I did was replace the tires. I bought Yokohama Prada Spec-X, which were rated #1 for this size. The goodyears on the car were rated 18. I never could have imagined what a huge difference this made for my ride - so much smoother, quieter, and felt more stable. Afterall, it's only your tires touching the ground!

    Go to message #164 in this group. You will see I had to replace my tires before 14,000 miles, all cracked. Go to a different Firestone dealer. My dealer replaced all 4 tires with balance and everything for $00.00

    My Mitchelin dealer did me the way you are being treated now. I had to pay over $300 for replacement tires 22 months old with 22,000 miles on our 06 Honda Ridgeline.

    Look around there are some good Firestone dealers out there. Good Luck.

    I must replace the two front tires. Is it true that the tires have pressure sensors? Is there a special feature to the tire that I should be aware of when buying the new tires.
  • bcp1bcp1 Posts: 21
    It is true that you have sensors on each wheel that monitor tire pressure/failure, etc.
    It the dealer is careful you may be able to reuse the sensor with the new tire change.
    Most dealers change the tire stems with placing a new tire, but the sensors are much more expensive. I had all four Bridgestones replaced because of cracking about 3 months ago and I only had 11,800 miles on the CX-7. They gave me four new tires at no charge and the sensors were placed back on the wheels with the new tires and no problems.

    My other vehicle is a 2006 Ridgeline RTL/S Truck and I put on Boss 381 chrome wheels and the sensors didnot fit, so I had a lot of problems getting replacement, so now I drive the truck with out the tps system. We put one sensor on the spare tire and it take the truck system about 20 to realize that the sensors are missing, it checks all wheels indiv.

    Hope this helps.
  • Mazda CX 7 i sv comes with standard 215 70 - 17 tires. Can these be replaced with 235 65 -17 tires if the diameter is within .2 inches? The higher level cx 7s come with 235 width 18 inch, so figured this would work as far as width goes. I thought that as far as a .2 inch change in diameter, it would be fairly negligible as far as change to overall speedo calibration and gear ratio/ performance aspect.

    I just put on 4 new Rims/Winter Tires on my Mazda CX7 and noticed that the tire pressure light stays on. With a bit of reasearch, I found out that my original rims have 4 TPMS Sensors

    If your vehicle is equipped with a tire pressure monitoring system they are installed in the tire and wheel assembly. Hope this answers your question.

  • I own a 2010 Cx-7 Sport and have discovered the the 235-65 17 bridgestone Duellers that came with my car are ONLY made by Bridgestone. I cannot purchase any other tire in that size. Does anyone else have a CX-7 Sport in an older year with that same size tire? I am believing the this size is unique to the 2010 models.
    I had to have Bridgestone replace all four of my tires at 6000 miles at no charge to me. My dealership doesn't have answers, Mazda Corp in Cali doesn't have answers, and the BBB wouldn't help either. HAS ANYONE ELSE EXPERIENCED THIS? I have owned many vehicles and the tires have lasted years not months. Any help or direction would be Awesome! Thanks!

    235/65/R17 ~This size is ONLY made by Bridgestone in the Dueller and the Blizztak. Does anyone else think this is HORRIBLE????
    Why wasn't i told about the limited tire availability before i paid 27,000 for this car?
    I have already had to replace my tires after 6,000 miles....BS! i need to know what i can do about this.

    I just went out to Tirerack's website and pulled up over 50 tires that are 235/65/17. You have a ton of alternative choices. You can also change up the tire size e.g. 255/60/17 are essentially the same size tire. You can play around with any tire size calculator (e.g. discount tire direct website) on the web to come up with various alternative sizes that will work (and not throw your speedometer off by very much).

    My Protege5 came with a "unique" OEM tire, when it wore out I just changed the size a bit to open up my options....

    Hope that helps.
  • I also have a 2010 i Sport. It only has 2500 miles on it but so far there seems to be no noticeable wear on the tires. However the OEM tires are Duellers in size 215x70x17. When I go to and list my car's model it states that the size of tire for my car is 215x70x17. I wonder if Mazda changed the size at some point because of the tire wear problem.
    According to Tire Rack there is no other brand of tire available for my car which I knew when I purchased it. There are also Hondas and Toyotas thatuse this size so perhaps at some point another manufacturer will make a tire in my size.
  • You just listed the same size, twice...

    So... which is it? lol

  • I was replying to the post by 2010zoomzoom1 (Dec 03, 2010 9:45 am) in which it states that the standard tires on the 2010 i Sport are size 235/65/R17. I thought that all 2010 CX-7 i Sports came with the size on my car which is 215/70/17 and that size is also quoted as the correct OEM size by Tire Rack. I wonder if this could be a reason for prematuire wear. I do agree that it is terrible to have no choice of tire in either of these two sizes. We are stuck with Bridgestone Duellers.

  • The correct tire size on my cx-7 is the 215-70-17....that is correct. I feel very strongly about not having any options on tires...especiall when the Dueller H/L in this size is a non mileagle warranty tire.....

    if i would have known this when i purchased the car, i would have went with the 18" wheels and turbo. I was think economical and it has kicked me right in the butt! I have filed complaints with the BBB, Attorney General with my state and with Mazda USA. I have gotten NOWHERE! i am ready to just trade it in.....when i had to replace my tires at 6100 miles, bridgeston didn't even have them in stock! i worry about this....what if i am traveling and something happens!

    Anyone looking to purchase a 2010 CX-7 i sport with only 12,000 miles?!?!

    Quite a few of the major tire companies including Michelin, Pirelli, Goodyear, etc. make tires in size 215x65x17. I just wonder if that size can be substituted for the original 215x70x17 Bridgestones.

    Good point...

    Also... 225/65-17 or 235/65-17 would be even closer to the original diameter.... if your wheels are wide enough.... 7.5" is plenty for either... 7" wheels will probably take the 225s.. but, might be a little narrow for 235s...

  • thank you for all your advice. I was told to totally recify the issue, i would have to buy an aftermarket tire package, and i could go with 18". How would that affect my speedometer?

    I just don't know why they even offer the FWD CX-7 if the tire availability is so scarce.

    it is such a shame that after buying the car brand new, 12 months ago, i am now looking into buying new wheels to fix something MAZDA should have caught in the beginning.

    i am just a little frustrated at this point.

    No need to go to 18", unless your 17" wheels can't handle a slightly wider 17" tire...

    The cheapest alternative would be to use the wheels you have.. Plus, switching to 18" will mean a lower profile, and may change ride/handling characteristics in ways you won't like..

    Plus, 18" tires are about 25% more expensive than comparable 17" tires..
