“1 year, +/- 20k miles since swapping to Toyo Tire Open Country A/T III 215 /75 R15 w DX4's Pocket 15 X7 wouldn't change a thing. 80% commuting, 20% fun. Soak up the potholes and dig in the snow. Softest, smoothest”

“I picked up a 24 AT4 on Saturday and swapped out the tires today from the good years to Toyo's. Same size 265/60/20 as factory and what a difference they make. No noise and a softer ride. I got a credit of $130 a tire and negotiated with dealer to give me $500 towards the new tires so not much out of pocket. Highly recommend. Now time for some new shocks which is a pretty daunting research project. Lots of opinions out there, but ranchos seem to be unanimously despised. Thanks forum members for pointing me in the direction of Toyo's.”

“I guess VAMike doesnt know what he's talking about... So i didn't actually get to do any serious 4x4. Everything in SC was dry, and i mostly walked around. But i can report of everything else. Highway noise is substantial. Its not any worse than other All Terrain tires, but its certainly not quiet. I did have to go get about 500 lbs of steel for a project, and the only trailer available was a 14000lb GVWR dual axle trailer. It towed just fine, though the tongue weight made the rear sag to the bump stops with no load. I averaged 19.5mpg, that includes ~70 miles of towing that trailer (3500lbs). For reference, my lifetime average is 21.8mpg, so i dont think my economy fell by more than 0.5-1. The only other thing i noticed that was of substance is that i shift down into 9th pretty often on the interstate, which im not thrilled about, but should have expected.”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
