#185 of 200 2010 Mazda 5 cupping on the inside of rear tires
Apr 15, 2012 (8:32 am)
Can someone please let me know if cupping on the inside of my rear tires would be an Alignment issue or a Balancing issue?
I had an alignment done on the car approx. 6mths ago and the tech said that the car was set to factory standards but when I got the car back I noticed when driving on a straight road the wheel was slightly off center. I took the car back to the dealer, they put the car on the rack and said that the alignment was dead on.
Now 6 mths later I am noticing cupping on the inside of the rear tires and a slight vibration at approx. 80km/hr and the vibration goes away as soon as I hit 100 km/hr.
I now have 25,000 km on the car.
Can someone tell me if this would be the dealers responsibility and what the best possibile repair would be?

Both mis-alignment and im-balancing can lead to "cupping". The problem is that people use the word "cupping" rather indiscriminantly. Technically, cupping is ONLY the result of im-balance, and alignment causes diagonal wear (and what precedes it - heel and toe, feather edge, etc), but it is very difficult to tell the difference between the 2.
So you now have a vibration. Did you rotate tires? You are supposed to.
Plus, the alignment specs for a Mazda 5 include quite a bit of camber - and that tends to wear tires irregularly. What your alignment tech should do is take out as much camber as he can.

OK - looking for a new set of all weather tires to put on my 2010 Mazda 5...consensus here from last summer is that it doesn't really matter too much since this car will wear out whatever...did the Kumho's last?

They've lasted over 30k for me so far and now need replacement. Sorry I can't give a more exact number, but some tires previous to these lasted only 15k and just over 20k. I guess the years of 50k and 60k tires are done.
I need to talk to my mechanic again re tires. He had some tires I'm going to try when I replace the Kumho's. Consumer's Reports also had ratings on tires that are worthwhile.
One thing my mechanic mentioned is it's really important to rotate these low-profile tires every 3k to 4k miles. I can't say I've been that good about doing it.
If I remember, I'll follow up here with more info from those two sources.

Jun 23, 2012 (4:38 pm)
I bought my car July 2010, the car had 36 miles on it. Replaced the tires after 23k miles which I understand is pretty much what everybody else is doing on here.
Went to tire dealer & put a 40k mileage set of tires on car June 2011. I've been rotating religiously, I go in June 2012 to have them rotated, I admit I am over the recommended mileage but hey I got it in there. The tire guy proceeds to tell me I need a new set exactly to the yr & onlu 23K miles on tires, ugh. He couldn't rotate said there was wear on the insides of the tires.
Am I to understand that I am going to have to replace my tires at a $585 cost (included the alignment) every year????!!?!?!?!?! This is ridiculous, is Mazda aware of this problem? Is there something wrong with my car? What can I do to get more mileage from my tires? (Newby here, haven't read all 19 pages of suggestions/complaints. This is insane!!!) I love my car & it's perfect for my family, but I have expenses & tires every yr isn't one of them!!!!

momsmazda5: Sounds like you might have some suspension issues. I suggest taking the time to read through all the messages here. There is some good info to be found. But I had the same experience with our 2006. The Mazda dealership acted like it was a big surprise. Then I found this forum.
It's discouraging since the vehicle is built pretty well. CU Reports gives the Mazda 5 high ratings.
Last tires on our 2006 were Kumho. I was replacing tires 2 at a time. I actually got close to 30k maybe 35k on the first pair, but one of the second pair developed a bulge on the sidewall so I had to replace all four. I put on Hankooks this time. I guess they're rated at 40k.
My mechanic told me the only way to deal with these low profile tires is to rotate them religiously. He recommended I rotate them every oil change. So that's what I'm going to try. Typically I change oil every 4k to 6k. I run synthetic so I stretch it a bit.
#191 of 200 Tires and Wheel Problems
Feb 25, 2013 (12:01 pm)
I've replaced tires twice since buying the car 2 years ago. I replaced a wheel last year because it was bent. Currently, there are 17" tires on the car and the tire shop I went to is saying I need to put 16" tires on it (but they don't know if they'll fit) and new wheels because I have 2 more bent wheels. I have a lot of shaking when going between 50 & 60 mph.
I know nothing about cars. I got talked into spending $1,000 on new tires last winter because the guy said they would last a long time. The nylon chord is actually coming out of one of the tires after 35, 000 miles. I am wondering if someone will tell me what to do here. Will 16" wheels and tires be the end of my woes? (The tire salesmen said they are more durable.) Or do I just put 17" on again - and pay more - again. Or do I get rid of this car? p.s. the gas mileage isn't anywhere near what the dealership said it was going to be.

If you don't mind the change in the look of the car, then by all means, go with the 16", with a higher profile tire. The tires will still last between 30 and 40,000 miles, but at least it won't be as expensive to change either tire or wheels. Keep in mind that you will also need to transfer the air pressure sensors that are installed on the original wheels.

Thanks for the advice. Does anyone know if Mazda offered the option of 16" tires on the 2010 Mazda 5? I would hesitate to change the size if it wasn't offered as an option. The tire guy thought "it would work" but couldn't give me a definitive answser.
