“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.”

Tire A

Cooper Discoverer Road Trail A/T

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.

“GEOLANDAR A/T G015 Anyone running these on 17" rims, stock or other? I have Enkei M52 rims, 17x7.5 and 45mm offset. What size fits without rubbing? 215/60R17 looks to be the closest, the only other size close is 225/65R17 which I think will be too big without a lift. I am open to other suggestions for off-road capable tires that will mainly be used on-road. K02 is out because they don't fit without rubbing, and I plan to add flaps at some point and do not want to lift the vehicle or get different rims.”

“I switched to Yokohama Geolandar A/T G015 265/65R18 114H SL BSW Corrected the speedometer (normally it reads under by a few MPH with the factory tires). They are AWESOME in heavy rain conditions and snow. AT tires, so they are slightly louder than the Defenders, but not by much. Slight rub on a hard turn, but you can replace the one bolt in each of the front wheel well trims and it's all better. They look great as well. Good luck!”

“Anyone here running Yokohama Geolandar A/T4 G018's? Any complaints or regrets (road noise, balancing issues, etc.), specifically in SL load? Currently have the Geolandar A/T G015's on my 4th gen and am considering the A/T4's next. All the real feedback (non-commercial reviews) I've been able find on here and other forums seem to be pretty old and mostly by people without a ton of miles on them. My use case is about 90% on road with the remaining 10% on mild to moderate trails. Not a rock crawler and never will be. The G015's in SL load have been pretty perfect but I've been thinking about changing to the A/T4's next for slightly better off road performance. Main concern (aside from weight, which is why I'm looking to stay with SL instead of C) is wet pavement safety since I drive my young kids pretty much daily. I only have a roof rack, so not too much added weight.”

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.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
