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 frontsThis 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.
