Looking at new tires

I finished adding Ceika 1M Coilovers Lowered 1 1/2”, Avant Garde 610 9” wheels and Michelin Pilot 255/45/R20 10” AS/3 tires, love it looks great, rides nice and handles much better.

Looks great. Those wheels are nice. Why did you go smaller in tires? Those Michelin tires are nice. Had them on another car of mine. Only thing is they wore out fast. Hopefully they last for you.
 
Hello I am an old dinosaur and this is my first forum. Please pardon my ignorance if I do something wrong.
I have a 2009 cx9 Touring. A friend gave me 20 inch factory wheels.
I want to go as big/ fat with the tires as I can and still have adequate clearance.
Any recommendations would be greatly appreciated.
Will 245/60R20s fit?
Thanks

Hi Led, welcome to the forum!

I like using this wheel size calculator. You can plug in your current setup and compare it with a different setup to see how things would change.

https://www.willtheyfit.com/

Your 09 being a Touring model, it currently has the 18" wheels, correct? If so, OEM rim size is 18x7.5 with a +45 mm offset, with 245/60/18 tires. If your friend gave you the OEM 20" wheels that came on the CX-9 up until 2015, they are likely 20x7.5 +45 offset. If they are the 20s from the 2016+ CX-9, the wheels would be 20x8.5 with a +45 offset. Either way, based on the calculator above, here's what you can expect.

With 20x7.5 wheels and 245/60/20 tires:

With 20x8.5 wheels and 245/60/20 tires:

In terms of height, the gap between the fender and the wheel would be about an inch smaller. In terms of width, since the 8.5" width wheels come with an OEM tire size of 255/50/20, you could probably get away with 255/60 if you wanted. If you have the 7.5" widths, I would just keep them at 245. Both options should leave you with plenty of clearance for paved roads and light off-road duty.

Just keep in mind that when you change the overall diameter of the wheel size, your speedometer readout will no longer be as accurate (detailed in the pictures).

Hope this isn't too confusing!
 
Thanks Brett! You are Amazing!
I have the 7.5s (20”) and my objective is to go as Tall and Wide as possible in an effort to look more like the old style Armada or Pathfinder look.
I presume my ambition is against the norm but I Love the car.
What would you recommend?
Thanks Again
 
I would recommend 255/55/20 As its a little larger but not by too much and still fits the rim width. I would recommend these two tires. Both are fantastic. I personally have the Bridgestone alenza plus and they have a nice truck like look to them and seem to be robust. Both have fantastic reviews and both are similar in price however you can probably get a better deal on the Bridgestone.

What area are you from? What type of driving will you be doing? Just want to make sure to recommend the proper tires based on your use and driving habits.


 
I can’t thank you enough Brett! We live in NJ. I’m an old man at 55 and the Wife drives a Lexus RX350- Incredible car. I Love the handling And the cargo room on the CX9- pretty awesome. Our Daughter says I drive like an old man and I pretty much do - I am willing to sacrifice some handling performance to achieve as Beefy/All Terrain look as I can. I respect and appreciate your expertise. If I Drive like a turtle only locally with no off road could I go a little bigger And still fit in the wheel well? If not I’ll go with your advice.
Either way I can’t thank you enough for your time and consideration!
Your car is Awesome by the way!
 
Where in NJ? I’m in PA by sesame place. I don’t think you would be giving anything up with either of those tires. Apparently the Bridgestone will last longer based on reviews but both get fantastic reviews.

Hey any update from Mazda?

Sorry for the LONG overdue reply! COVID hit just after I took the car to the dealer and then everything fell flat unfortunately. I explained my concerns to the service manager and gave them the info I had from Mazda corporate. Corporate also had my visit information. They inspected the car, tires, brakes, suspension, etc and everything checked out okay. I followed up with corporate and they said their hands were tied.. Followed up with Bridgestone / Firestone and they said sorry we didn't sell you the tires, Mazda did, so take it up with them.

So in March I had a 6 month old car with less than 5K miles on it, closer to 4K if I remember correctly and the tires were absolutely useless in cold weather. I have two curbed rims from when I slid sideways during a 10mph turn in an inch of snow in February. My RWD Dodge Charger handled better in the snow...

I will be going to a local tire shop to get new tires before this winter, probably one of three mentioned in this thread. It'll be a shame to toss tires away with only 7K miles on them but I can't risk my family's safety.

Anyone run Continental tires on their CX9/5? I had a really good experience with their DWS06 line. Not sure if they make them for our cars through.
 
It is amazing that the Bridgestone ecopia are branded as all-season tire. Same goes for the falken, they are a nice sticky summer tire, but just a look at the thread and I know they would be terrible in any kind of slush and snow.

Have you considered running a dedicated set of winter or (Four season tires during winter)? That way you can keep using up the thread on the ecopias in the summer to minimize your losses.

Very strange.. I had the Ecopia tires on for nearly 2 winters. Once I had adjusted the tire pressures to the correct PSI, they behaved as well as I could expect for all-season tires.

Gardidien, if you're still willing to deal with Mazda Corporate, I would attempt to get the issue escalated to a manager at Mazda Corporate. If you've already tried to do that, I would file a complaint with the BBB.

I triple checked the tire pressure myself and the dealer checked as well. The PSI is correct and within spec. Tires are fine in spring / summer / fall but once there's a drop of snow on the ground I might as well have racing slicks on the car.

I can try Mazda Corporate again but I feel like they're going to be even more unwilling to work with me now that it has been a year since I purchased the vehicle. BBB might get someone's attention.

Oh I wasn't suggesting that you had overlooked anything, I was just stating my experience with the tires.

In any event, I hope you can reach some sort of resolution. The OEM tires on the CX-9 (whether they are Bridgestone or Falken) leave something to be desired.

Didn't mean to imply that :) I'm just as shocked that people have decent experiences with these tires.
