Mazda CX-9 Tires and Wheels

buyer101

Your OEM wore out in 20K miles ?

Most CX-9 owners can attest to that mileage range in worn out tires...me included.

Not surprising.
Most OE tires nowadays have low wear index (UTQG). The OE tire is rated at 260 only. In my past experience, it lasts about 26K for me. Your mileage may vary.
Mine was replaced at 25K (it could have lasted some more, but I couldn't wait to get rid of it.)

I sent my car to shop this morning with bad steering vibration and really loud noise. The shop commented that I need a new tires. I have 37K on odometer. Can worn tires be really causing the steering vibration?

davicho

In certain cases...yes!

Vibration as you described can be caused by:

Worn tires
Unbalanced wheels
Bent wheel
Out of alignment

If you still have your original tires at 37K miles consider yourself lucky to have been able to get that much out of them.

ceric

Of course.
As tires wear down, they become unbalanced on the wheels.
Vibration w/o braking is usually (1) unbalanced wheel/tire (2) alignment
If it is alignment, you can spot problem when looking at the thread blocks of your tires. Uneven wear or one side wears more than the other on each tread block. If not, and it has been many miles since last tire balancing or mounting, it is likely the balancing issue.

Thanks all for reply. Actually I had my tires balanced couple of months ago (after putting the RunFlat into one of them ). And right after that I had an alignment done. This is why it was surprising. But I see everyone is getting Yokohama Parada tires - so I will have my dealer order them too. With installation it comes almost even to ordering from tirerack.com and having them installed eslewhere.

Got 29k out of the 20" Bridgestone H/L's on our '08 FWD GT. Still some tread but were very noisy. Yokohama was back-ordered on the Parada's, Discount Tire was quoting 6 weeks for delivery. Took a chance on the Michelin Latitude's in the same size and have been very pleased. Quieter and a better ride than the Bridgestones and I haven't really noticed any loss of steering feel or crispness, although we don't drive our CX-9 that hard. The Michelin's are standard in this size on the V-6 Toyota Venza so they are available pretty easily. Pricey though at about $200/tire. Only option significantly cheaper were Pirelli Scorpions which I've had bad experience with on another vehicle and size, and the Goodyear RS-A's which haven't received great reviews either. Hope that helps.

FWIW, i have Pirelli Scorpions STR A 20" on my CX-9 GT AWD and they have been very good even through a snowy winter here in NJ. i got them for $400 for the set of 4....great upgrade over the Bridgestone Duellers - better handling, quieter, and better wet traction (comparable dry traction - but pretty much everything is good on dry these days).

i'm about to change the original tires on my cx-9 gt awd, is it ok to replace it with a wider 20" tires? do i need to change my original wheels if i do this?and lastly, is it going to be a problem of any sort? :confuse:

memasterac

It depends on how much wider you are planning to go. If it is 255 (OE 245) I think you should be OK due to our OE wheel's 7.5 inch width. I would not want to go wider than that (although you still can) personally just because our OE wheel width is not suitable for wider tires. Aftermarket wheels on the other hand allow you with much more choices, you can go 275 or even 285 with properly selected wheel width and offset.

There's obviously lots of variability of opinion on these stock Bridgestones! We drive a 2009 GT, frequently with lots of kids and stuff, and we're approaching 35k. While I'm REALLY looking forward to the benefits of new rubber next month, our Bridgestones are still relatively quiet, no signs of hydro-planing, and with a surprising amount of tread remaining. We don't baby it in the corners, but we do check the pressures every 2-3 weeks, keeping them around 35#. While getting new tires is always fun for those of us who like to drive, I'll be happy if we get as much useable life from the Yokos as we have on the stock tires on a vehicle of this weight.

I need help deciding which tires to purchase. I've heard and seen a ton of recs for Yoko Paradas ($870 installed), but the tire dealer rec Good Year Wrangler HP($635 installed). What would you choose? We just moved to WI, so we plan on purchasing snow tires next winter but my car needs tires now. I've had it a few months and it slipps horribly in this snow

Replaced my Bridgestones last year with Goodyear GSA model. These are quiet, good traction, etc. About the same price at the Goodyear Wrangler HP, so take your pick. The Mazda dealer actually sold me the tires, and believe it or not was cheaper than my local Goodyear store. Probably worth asking your Mazda dealer, if they are close by.
