manufacturer-approved tyre degradation

Greetings everyone,

I returned from Discount Tire just now. With a mileage of somewhat under 12,000, this was the third tyre rotation on our CX-70 TPP. They advise replacing it at 4/32 when the tread depth is 6/32. Does anyone else's OE Toyo tyre tread wear out before the expected time?

Yeah, the factory-installed tires on them are notoriously bad. A lot of people are noticing it. At around 15,000 miles, you should replace your tires.

Yesterday, I watched a video on YT that discussed the link between low tire pressure and early tire deterioration. The driver door label instructs to pump the front and rear tires to 36 psi, however the Toyo tires on my CX-70 have a maximum pressure recommendation of 51 psi. Running a higher pressure reduces the amount of wear and tear on the tire's outer layer, which in turn increases the tire's longevity and fuel efficiency, as demonstrated in the video. Because each tire has a code number that indicates the month and year of manufacturing, the video showed that the tires wear faster when the pressure is lower than what the manufacturer recommends. They recommend getting new tires before the fifth or seventh year on the road since some insurance companies refuse to pay out after an accident involving tires that were supposed to have been replaced by that date. Before you buy tires, find out if they are covered by your insurance (AI suggests 6 years). I tend to agree with the video that inflating them to a pressure greater than 36 psi will make them live longer.

Mazda recommends 36 psi. It enhances both safety and wearability. Maximum pressure is 51 psi, not target pressure. Uneven wear and poor grip are consequences of increased pressure. Glue the door decal on.

What sort of claim is this? Your source must be posted.
Your vehicle's stability and control will be compromised with higher tyre pressures, particularly those above 51 psi. When it comes to setting the pressure, the engineers at Mazda go to tremendous pains to find the sweet spot between comfort and handling—36 psi—and I'd rather have their word than that of some anonymous YouTuber. Furthermore, I have never heard of an insurance company refusing to pay out because a tyre is too old! I couldn't agree with you more!

Simply put, 51 psi is the maximum level that I am aware of. For the majority of my vehicles, I aim for a pressure of 40 psi, even if the tyre manufacturer recommends a maximum of 50 psi. Thank you for responding, though; it might be useful to others.

With the 19-inch wheels, I have a preference. 19500 miles in approximately 7 months with all four bearings ranging from 6 to 7/32nds. Here we have the Toyota Open Country. Tires are not terrific, but I expect them to last 40,000 miles.

My go-to tires for long days on the road are the same, Toyo Open Country. The TPP here has been running for around twelve months. As mentioned before, we are currently at 6/32 with somewhat less than 12,000 miles on the odometer. I have my doubts about their ability to provide the mileage you desire. We've gone above and beyond the recommended three times to rotate and balance the tires and wheels. Let me know if you're keeping anything special from me.

If they barely last 15,000 miles, it might not be worth it to rotate them. Unfortunately, their unusual breadth of 275 makes them unusable. There is a dearth of reasonably priced alternatives.
