Mazda5 Tires & Wheels



  • rcinmdrcinmd Posts: 139
    From what I have seen, there are 16" wheels available for the Mazda5. I'm wondering if anyone has determined whether or not a 15" rim is available, or might there be clearance issues with some of the brake or suspension hardware? Doing the math, a 195/65-15 tire is a near perfect match to the OEM 17" size in terms of overall diameter.

    You need a 16" rim minimum to clear the brake mechanism on the M5. This is what my Mazda dealer told me.

    The Costco I use now puts nitrogen in their tires (its what the sickly green tire caps mean). They don't charge anything if you buy your tires from them. I have noticed that I don't need to repressurize the tires as often to bring them back to the specified pressure. If the tires are at the correct pressure, they'll last longer. Its sort of surprising that I noticed a difference since air is ~80% nitrogen anyway.

  • Since air is almost 80% nitrogen anyway, I'm not sure what that extra 20% buys you....

    The theory is that the oxygen content in the air combined with the heat generated by driving, over time causes an increased level of oxidation to the rubber inside the tire.

    Could be. My guess is that the tread is going to wear down to the point that the tires need to be changed long before the tire becomes useless from rotting away from the inside.

    I agree that 20% more N2 shouldn't make much of a difference (see my post). But my experience is that it keeps tire pressure better.

    I did some research on the web. See link I think that the main effect might be the lower moisture content in the gas. If you use normal air, it contains moisture and this moisture can change the pressure as it heats and cools. I believe the nitrogen is low moisture content.

    I've heard the same about moisture and more consistent tire pressure withregad to racing tires. Of course, their tires are dealing with a different set of problems than street tires!

  • Hi, i was just wondering if anyone knows what the max tire size would be for a 2002 mazda Protege 5 ? My bro just got one and wanted to upsize the tire cause of the cost on the low profile. i was thinking a 205/55R16 would fit but i need to know if it would fit or not. PLSSSSS help i could not find info anywhere else
  • You might want to check on the Protege5 forum, but since I have both a Mazda5 and a Pro5 I'll tell you I have Kumho Ecsta Supra's on the Pro5, they are 205-50-R15's. No clearance issues,much better wet traction than the Dunlops at 25K, but they wander over road imperfections.
  • I meant 205-55-R16.
  • My wife, who mainly drives our 5, is complaining about front wheel slippage in wet conditions and is already fretting about snow. I thought I'd get a set of 16" wheels and different tires, as others have done for winter. But here's my worry, will a winter-pattern tire be even worse in the wet? Grateful for any suggestions. We live in Washington D.C., so we don't need an aggressive snow tire.
  • Nitrogen molecules are larger this makes it harder for them to escape. The Oxygen and moister and other gases are many more times easier to be released from the tire. If you check your tire pressure every week (which few do) then what you put in your tire is of little concern. The issue comes in when the tired pressure decreases as this will affect tire ware and gas mileage.
  • Hi everybody!
    I have a Mazda5 GT and I would like to know if I can change the regular size with 215/50/17...Thanks in advance.
  • I am sure that you can put on the wider tires. It will affect several things though - all due to the larger tire. 1. the speedometer will be out (you will be going faster that your dash says) 2. It will take more torque to get the wheels going - but the revs will be lowered on the highway. 3. the wider the tire that farther it takes the water to be expelled in the rain (more chance of hydroplaning - this is of course based on like tread based tires). 4. you will have more traction in the dry weather as you will have a larger footprint on the ground. 5. the car will sit higher...well that is my 2 cents hehe. I will go for wider tires myself after my 17" ones are burnt off. as the front is so light there is very limited traction with the toyo crap tires. lol
  • thanks athenasius, much appreciate the info....what tire do you intend to put on? and yes, Toyo tires are really junk.
  • I'm thinking of getting a set of Hankook tires to replace the Toyo's I currently have before next winter. I'm sure by then I'll have around 50,000km. I currently have 36,000km and the Toyo's aren't gripping like they use to when brand new. Currently, they are 205/50-17, but would like to go to 225/45-17. This will keep the same diameter but should give better handling if not a slight loss in ride quality. HAs anyone else changed to a different tire size similiar to this? Would really like to know if it makes a difference, thanks!

    Sorry Caliaghi, As i have winter tires I will not have to replace my toyo crap for a bit. Next spring i will start to look into it. For a starter I would make sure the tire had great sips(as the front end is lighter that the rear.
    Winter tire: For anyone interested these are my winter tires. I have never been stuck and have been in snow well above the door sills. They are great on the highway and in town. I went down to 16" as the increase sidewall increase winter tire traction. AKKAPELIITTA+RSi
  • I was reading a UK web site Some folks in the reader review section were saying that the UK version of the 5 has been giving problems with premature tire wear (tyres in UK speak). We have 12000 miles on our 5 after 2 years and the tires look fine and are wearing evenly. anyone seeing anything like this?
  • I would like to help clear the air and provide an understandable explanation about tire balancing, Road Force, etc.....

    After reading through some archived messages, I feel disheartened about all the misinformation that has been conveyed to consumers.

    My name should let you know- I am an ASE certified auto technician that now works much closer to the tire and wheel industry in a very unique way that I promise can help you understand what is going on with your vehicle and why certain remedies work sometimes, and why some work all the time.

    My goal is to help anyone better understand what they can do to eleviate their own frustrations by making sure the job gets done right the first time.

    Fire away!!!

    My apologies in advance for barging in on this posting- I am a new user and can not find where to post a new message- any help would be appreciated.

    Try posting on the forum "Tires, Tires, Tires"

    But I should warn you, there are some fairly knowledgeable folks that post there, so you better have your act together.

    I think the 50 series tires on the Mazda5 are silly (and expensive!). Has anyone tried a set of 15" rims with something like 205 65 15 tires? Should be roughly the same diameter, but tire life is likely to be longer, and tire cost is likely to be much less.
  • riproyriproy Posts: 57
    Anything smaller than a 16" rim will not clear the brake mechanism. Sorry..

    I have a 2006 Mazda 5 and the tires are WORN and need replacing at just 17,000 miles. I did have a recall on both the front and back suspension and had it all replaced so I think the premature tire wear on the TOYOs are due to this. In any event, Mazda is replacing my tires on warranty and they should. Good luck! :P
  • I just had to replace all 4 tires at 29,000 miles they are the 205/50R/17 and they are expensive, the cheapest I could find are BF Goodrich at 141.00 per tire if you want the expensive ones just try Good Year Eagles almost 200.00 per tire, these tires are high speed rated tires, who the hell is going to drive around at 140 + in a little mini van? There needs to be an alternate tire that at least gives good tread wear!!

    Have you try discount tire direct? It has Yokohama YK520, for $109. Mileage warranty is 60K miles.
  • maltbmaltb Posts: 3,572
    You should try it, it's fun!

  • My sister has a 2007 Mazda 5, it has 3000 miles on it. It hit a pothole and blew out the whole side of a tire. Is this covered under warranty? And exactly what size tire did this model come with? What is the least expensive replacement tire on the market?

    Thx in advance!

  • :(

    The stock tires are Toyos A18 205/15 R17 (US, it is marked on the tire side). I'm afraid to say that that issue may not be part of the warranty as is not a tire defect.

    With so few miles I would look for the same Toyo to replace it. Now, worst case scenario, if its really pricy or you don't find the same Toyo, I would at least get a couple of a different brand tires and replace them in the same axis (front or back) so they wear uniformly, otherwise only one different brand tire may make the car feel weird or not very stable.

    Anyway, here is a good site:

    Well I must admit..I'm in the U.S. and I bought my 2006 Mazda5 used (22k miles) and it had new tires. I wondered why in the world a car with only 22k miles needed new tires. I had a talk with my father about that issue and told him I was weary of buying a car that I would have to buy $200/each tires for every 20k miles but he explained to me that the type of tires on the Mazda5, how the Mazda5 drives/handles, etc. CAN wear them down quick (and bad) if you do not keep an eye on the pressure. I'm thinking of getting them filled with Nitrogen......
