Pizza cutters vs go wide for the gram

[J1000]

I really like this guy's videos, super methodical and well made. Judging 315s vs. 255s does leave a lot of room in the middle. I think on a lighter truck like the FJ 315 is just too big. Personally, I tried skinnier tires on my 100 but didn't like them, both on and offroad. On the highway the truck rolled over more in corners and in Moab they didn't give the same grip. Also I noticed that at street pressure they were the same height, but once aired down the skinnier tires noticeably dropped the vehicle lower about 1/2 inch. My 100 is a heavier vehicle and I think tire width should scale with weight.

LongCruiser is on Kenda Klever R/T 35 x 10.5 (266.7 MM) R 17
I think they look more proportional than the 315's it had when I bought it.

7.00 x 15 Pizza Cutters on the Working Pig have served me well for the past couple of years. I haven't had use chains since swapping over. But, since the Working Pig can sit for long periods of time in the cold they will flat spot.

It was definitely a good video. My only challenge to his data is if (I say it does) the BFG performed better because it already had miles on it and the tire was “broken in” and therefore the sidewall more flexible to some degree.

I'm pretty sure a tire hardens with age, not softens. If a tire is getting softer I'd suspect your cords are breaking, literally broken.

I would think there is some immediate gain in flexibility from brand new then a slower hardening after that.

Certainly the tire design played a role as well. But I’d love to see the same tests applied to those Micky Thompson’s after a 1000 miles.

Tires do have an initial break in but most of what I've seen suggests that maybe 500 miles before all the compounds are leached, reactions complete and the rubber is what it is. After that it's all deterioration, work hardening and fatigue.

With my new 2022 4Runner I struggled with new AT tires for first set without a lift. My research led me to the same general conclusion, that narrower is better for more overlanding related travel with many highway miles. I went for less wear and tear on the drive train and better mileage for the first set of tires. I have survived Slaughter House Gulch annd Argentine Pass (high road) as well as several easy trails. My gas mileage on a current trip from Denver to Seattle was just a little over 20 mpg. I’m running Toyo Open Country AT3, 255/75/17 with a 0.4” increase is radius - 32”
