Stock Tire Life

:
2017 Mazda 6 Sport
This morning, I rotated the stock Toyo A36 tires on my '20 CX-5 Signature for the first time at 8,022 miles. The tread depth started at 10/32". The fronts had 6/32". The rears had 9/32".

Based on a minimum required tread depth of 2/32" in Texas, I used half of the front's legal life in 8,000 miles.

If I rotate every 7,500 as suggested, the front tires will be slick at 22,500 miles and the rears will be down to 4/32".

If I rotate more frequently, I might be able to squeeze 25,000 out of them before they'll no longer pass inspection, but they'll become unsafe in the rain long before that. Wow.

I suspect the root cause is a heavy foot, 320 ft-lb of low-RPM torque, and an AWD system that can't send as much power to the rear wheels as the iVTM-4 system in my previous Hondas which wore tires much more evenly and less aggressively. :)

what was your tire pressure for those 8k miles? how much weight do you usually carry? you might want to try going up 2-3 psi on the fronts

Tire wear seems about right.
Those are soft compound and also wear faster. i.e generally 25 to 30k, rarely above 30k and they are out.

35 PSI as specified by Mazda

150 lbs. (me)

The wear was even across the width of the tires. Why would I want to overinflate them and wear out the center faster? :)
going up 2 psi on the fronts will help tread wear without hurting even wear

you may just have to rotate tires more often.

If we rotate tires more often, we’ll get more miles out of them. In fact, Mazda recommends 5,000-mile tire rotation interval for gen-1 CX-5 including my 2016 MY instead of 7,500 miles.

Looks like this should be the case. I have 2.5L AWD and my Toyo A23’s currently have 42K miles with 3/32” tread depth left. I rotate tires at 5K interval per recommendation.

How so?
To me, factory recommended tire pressure is based on factory tires. Once you switched tire brand, new tires may have different characteristics than the factory ones, and may need different tire pressure to get the optimal performance. From my experience the factory recommended cold tire pressures seem to be too low most of time unless they list several recommended tire pressures based on the load and speed found on many European cars. An extreme case is my 1998 Honda CR-V where 26 is the recommended tire pressure, but I have to use 35 psi to get good performance and even wear on General AltiMAX RT43 tires it uses. On my 2016 CX-5 GT AWD, I’ve been using 39.5 psi on my 225/55R19 Toyo A23 factory tires over recommended 36 psi, and getting the even wear across the width of all tires. All tires currently have 3/32” tread depth left at 42,060 miles with 5K-mile tire rotation interval. And I believe dunhillmc’s suggestion is legit, at least it won’t hurt the even wear on your A36 tires.

I should have checked the tread depth and rotated the tires sooner instead of ASSuming tire wear would be similar to my AWD Hondas. :)

Given the frequency at which I trade, I'm unlikely to own the CX-5 by the time it needs tires. Mostly, I was just caught off guard by how quickly the front tires are wearing.

If they've worn evenly across the tread, sounds like you could go another 8K to get to 5/32 at that point they are all even, might as well leave them where they are at for another 4K which gets you 3/32 in the front and 4.5/32 in the back. Do your final rotation and start shopping for tires.

So one rotation at 20K miles on the car and final at 4K more gets you to 24K total miles down to 2/32" tread.

BTW, nice video, I just noticed that. I wish my garage were that open and neat. In the next few days I'll be doing similar, swapping on the winter wheels, replacing the brake fluid, and swapping rotors and pads on at least the rear, maybe all 4 depending on how I'm feeling and how much time I have. I got all the parts, but noticed the OEM front pads still have a lot of meat. I'm at about 35K miles, still good tread on OEM tires, but there's probably 8-10K of that done on the winter tires instead. I only rotate during the seasonal swap. I don't necessarily want to get every last mile out of the all seasons, and I won't put enough mileage on the winter tires to wear them out before they should probably be replaced due to age.

replacing the brake fluid,
Just curious, which method (or tools) do you use to replace the brake fluid? I stilly use old-fashioned 2-man pumping the brake pedal method but that requires my wife is in a good mood ⋯ ;)

I'm going to do the 1-person pump with tube submerged in elevated bottle of brake fluid. With my previous cars I've used speed-bleeder nipples that had a check valve in each, but they don't seem to have them to fit the CX-5.

I have a bluetooth camera I'll set up so I can watch from the driver's seat, so I should be able to see if there are bubbles and when the fluid runs clear.

My wife helped once or twice, maybe on her car. There are enough variables in planning to execute the job, now I know better than to count on asking for that help. Maybe my daughter will help when she's a little older.
 
UTQG treadwear ratings are a rule of thumb to be used in the absence of other information but they can be misleading. These ratings are determined by the manufacturer and are not confirmed by any governmental testing. It is self-regulated in essense and there can be wide disparities between the treadwear rating and real world experience.

Consumer Reports, for example, tests tires for about 15,000 miles over real world roads and then projects an expected lifespan. For example, the 245/60R18 Michelin CrossClimate SUV with a treadwear rating of 680 and a treadwear warranty of 50,000 miles tested out as a 40,000 mile tire. The 245/60R18 Continental CrossContact LX25 with a treadwear rating of 740 and a treadwear warranty of 70,000 miles tested out as an 85,000 mile tire. Individual experiences will vary base on driving style, road conditions and other factors.

It's funny (or not) how many of the asphalt roads in Florida where I spend a couple of months every winter are oddly coarse. Evidently crushed sea shells are in the mix. In any case, a local Toyota service manager told me they often see OEM tires shot in the 20's of thousands of miles which I would attribute to the road surfaces.

If treadwear is a priority it's probably best to look for some independent testing beyond the treadwear rating.
Hello from your South Florida CX-5 owner. You could not have been more correct about our roads. They are brutal on tires! In my opinion we don't get anywhere near the mileage rating on our tires. I bought our CX-5 with 24k on it and they had already put brand new tires on it.

I live in CAPE CORAL FL, Many roads are call shell roads and that's why the name of the town is cape CORAL. Ed
