Michelin Defenders and warranty

[CANCERDOC]

I have a 2024 dual large T. I replaced my OEM 22s after 21,471 miles (they were all at 3-4mm tread depth) almost 2 months ago with a set of LTX Defender 119s at Discount Tire with a price match from Costco. Costco would not allow 115XLs because my yellow door sticker says my truck requires 116HL-rated tires -- yes, I know 115s were installed as OEM on earlier model year Ts, but the sticker is the sticker and lower load-rated tires are not allowed on my particular R1T per Costco policy (would've been the same at Discount Tire also).

My mi/kWh with the Pirellis was 2.70. I have put 4,568 miles on the Defenders, and my mi/kWh has since gone up to 2.73, and sorry, I didn't reset the trip odometer, so it's a blended number, strongly suggesting my mi/kWh with the current tires is actually even higher.

I have them inflated to 62 psi cold (they attain E rating at 80 psi), and I suspect that has made the biggest difference in my improved efficiency, in essence overcoming the additional weight per tire. In the photo below, the even higher psi is because of ambient temps and I was just out driving.

I'm quite satisfied with the tires - haven't had the opportunity to experience them in snow for obvious reasons, but that'll happen.

I also have the 119S 22’s and have been trying different pressures. At 55psi I’ve noticed approximately 5-10% efficiency loss compared with the worn down Pirelli 22’s (which oddly got quieter and much more efficient the more they wore down). I bumped them up to 58psi tonight and will try this out first.

I run my 119’s at 60-65 and i’m getting around 2.04 efficiency. I have a rack on my T so that probably doesn’t help (efficiency goes way down with a tent at 75mph LOL.)
