Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

We haven't collected enough community discussion about this tire yet.
Community sentiment toward the Yokohama Geolandar A/T G015 is predominantly positive, with owners highlighting its quiet highway manners, strong snow and wet traction, and good light off-road capability. Criticisms primarily center around a slight 1–2 mpg fuel economy loss, potential ride harshness or softer P-rated sidewalls depending on vehicle application, and gravel retention in the tread. Many drivers consider it a balanced all-terrain tire suited for predominantly on-road daily driving with occasional trail use.
“I may up the pressure to your suggestion - I'm running the door jamb recommended 39 PSI all around. I pick up little pebbles in the tread all day, every day, I notice. I have noticed a ~2 mpg loss on fuel economy, which really adds a lot to the "price" of the tires. Are you seeing any worse MPGs?”
“Changing tires (General Grabber AT3 vs Yokohama Geolandar A/T G015) Halloo I am about to pick my RR next month from the dealer and I am thinking if it is a good idea to change tires. Here is the context: I am buying the RR because I always wanted to drive a truck and I love American cars in general (I also have Mustang s197 V8). In fact I want to switch from Wrangler Sahara, which is a great car BTW, however after 4 years and only 20.000 miles I know I miss more comfort. The rest of my family even more ;-) 95% of my trips is on reagular roads, city cruising. Sometimes some rural paths (no heavy offroading). My Wrangler came with Duelers, which I replaced with Yokohama A/T G015. The difference was night and day as far as wet and cold. Here in POLAND we have two seasons: it is either hot and wet or cold and wet. Winter in my area is pretty light, however I go to the mountains once a year. So the question is: As I do not know how General Grabber AT3 works, but I trust Yokohoma G015, is the change the tires worth it?”
“Yokohama Geolandar A/T G015 Snow performance. I'm currently running Yokohama Geolandar A/T G015's on my 2013 Subaru XV (WIP) and I live in a semi snowy area and also work in the mountains on construction sites in Japan. My co-workers keep telling me I need dedicated studless (Winter) tires but I had zero Issue with my current tires last year. I got a little stressed out and paranoid about it today when they mentioned it again, yet they have all had slippage on snow with their dedicated tires yet I had zero. Am I over thinking things? My co-workers are asses to be honest, but anyway I've attached some photos of the sort of conditions I drove in with zero trouble, yet they had slippage coming up the hill into the jobsite.”

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.
