“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.”

“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.”

“I have Yokohama Geolandar A/T G015 on my explorer and they have been great on the highway, towing, off road. 2 summer seasons so far and they still look nearly new. I use winter tires so far in winter tho... My other vehicle (AWD Delica minivan) has chinese brand RoadX RXquest AT QX12 and they have been amazingly quiet on highway - have not used in winter or highway but i will be using them this winter as they are rated 3 snowpeak so qualify as winter tires for my insurance...no issues with handling or wet performance noted so far. only had them on a few months so cannot comment on tread wear.”

“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.

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