Tire A

Kumho Solus HS51 Harmony Sports

We haven't collected enough community discussion about this tire yet.

Tire B

Yokohama Geolandar A/T G015

Positive

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.”

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.
