Mazda CX-7 Tires and Wheels



  • My tire problem went away and got fixed after 3 weeks of discussion with the service manager and diplomatic negociations... The bottom line is that I did not pay one dime for the 4 replacement Turanza tires as I negotiated that Mazda Canada would replace 2 tires and Bridestone Canada with 2 new tires at their expense. I now have 4 new Turanza OEM worthless tires but now I can look and buy real & proper sized tires for my CX7 with my money...

    Good luck to all with this problem!

    Cant seem to locate the thread, can you be of more assistance ?

  • sdbobo619sdbobo619 Posts: 13
    Mazoommang11 is correct the Pirelli Scorpions are the best all season tire available, they easily outperform the goodyears and bridgestones which are OEM for this vehicle and complete garbage....

    The Scorpion comes OEM on Cayenne, Range Rover, Volvo, so I know it is worth a little extra money.

    Our 07 CX-7 GTFWD will be three years old in Oct. 2009. We have just over 12,000
    miles. Our OEM tires by Bridgestone were all starting to crack between the treads.
    I called my Firestone dealer and he told me to bring the vehicle in. After checking all 4 tires, he said that they would be replaced. They were balanced, new valves stems,etc. all at no charge to me. I am hoping that these will last longer. I had the car serviced last Dec. and they changed the module that controls shifting. It tends to not want to go into 6th gear unless I let off on the accellerator. My gas milage has dropped to 15mpg in town, but I get 22.5mpg on the hwy. The new tires ride quite well
    but I only have about 500 miles on them.
    I am due service at 14,500 miles and I will have them address the transmission situation. Overall, we really do like the CX-7.
  • We are very satisfied with our Mazda CX7 other than having someone steel the front grill Mazda "M" logo at a grocery store parking lot in broad day light and the Bridgetone Turanza crappy OEM tires... Futher update to our 4 new Turanza replacement tires, we have 33,000 km and the new Turanza tires (replaced at 18,0000 km are starting to show wear and will need replacing at the end of summer (in 3k-5k km). Based on my quick research on tire rack, unless someone else con recommend a great replacement tire, I am thinking on going with same size tires Continental Cross Contact UHP 235-60-R18. They have good reviews from buyers and users...

    I am sure

    I purchased a Mazda CX 7, 10 months ago. I have less than 8000 miles on it. Last Thursday I noticed that my tire was almost flat, so I took it to get looked at. They brought to my attention that on 4 tires are dry rotted! So, today, I took it to the Mazda dealer I had purchased it from. Mazda has nothing to do with it, Bridgestone does. And, Bridgestone will only cover 50% of each tire. I would not have a problem with paying over $300 for 4 new tires,if I had more than 8000 miles and the car was a few years older. They also proceeded to tell me that my tire tread is 50% can this be, its not even a year old with less then 8000 miles. I take very good care of my cars, oil changes every 3000 miles, my tires were only rotated once at 5000 miles. I just don't think it is fair that I should have to pay anything, the tires should be covered under my warranty...HELP :confuse: !!

    Is it ok to just replace only 1 tire for the cx-7? I had a slow flat from chicago on a 6 hr drive and checking on the tire every 2hrs putting air cause it looses 5-8 psi. I made back home and installed the spare right away. I bought two tires even on just 1 flat. So is it ok to install just 1?
  • bcp1bcp1 Posts: 21
    Most Mfg today recommend that you change your tires at least in pairs. If you have
    several thousand miles on a tire and loose it to a flat. The single new tire replacement will possibly affect the function of such safety features of Traction control, etc.
    Any time you have a great variation in tire tread depth, it will affect the ware and tear on the tires presently.
    Most people put two new tires on the front, because most vehicles are FWD.

    Remember that the CX-7 comes standard with Dynamic Stability Control(DSC) and Traction Control System(TCS)

    If you check your manual you will see a schedule for tire rotations and which tires go where.
  • steverstever Posts: 52,462
    As counter-intuitive as it seems, the better practice for FWD vehicles is to put new tires on the rear axle.

    I went through the same thing that you are going through. I guess the main difference is I went to a Bridgestone dealer that I was familar with. I would try another dealer across town, etc.
    They replaced my four dry rotted and cracking tires with balance, new vales stems, etc. I paid $00.00
    That is a new vehicle for all intents and purposes. Find out who the Regional Mgr for the local dealers is and ask for phone number. I would take it to the top of Mgt.

    I know that Bridgestone as a Mfg. does not want their customers to be treated that way. They could loose your business for life.

    I dont know where you live but here in SW La. our dealers take care of their customers.

    Good Luck and dont take NO for an answer.

    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!
  • NEW 2010 Mazda CX-7 i SPORT

    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.
  • kyfdxkyfdx Posts: 117,319
    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.
    Here is the post in question:

  • 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?!?!

  • coastercoaster Posts: 46
    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.
  • kyfdxkyfdx Posts: 117,319
    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.
  • kyfdxkyfdx Posts: 117,319
    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..
