I purchased these tires because of 3 facts . number one they fit on my Factory wheel . number 2 they were all terrain tire Number 3 They had the 3 peaks snowflakes symbol. legal snow tires. So I can drive them as a winter tires as well. Also was pretty cool that they were supposed to last 60,000 miles and I got them from Discount tire direct So less than 120 tire Is about $50 cheaper than tire rack or anywhere local.

My initial impressions of this tire before I ever put him on the car with that they did not look as aggressive as they did in In that the rubber was super supersoft However once there on the tire inflated they did look much more aggressive . My initial driving impression Where that They were actually quieter than my stock tires with 42,000 miles. They were also awful in the terms of dry pavement haldeling. especially when Switching directions back and forth they felt walloe, soft and almost dangerous. However when I got home I found out that each tire was more than 10 PS I low. I'm gonna put some air on them and take some pictures of the clearances. In probably take them out for another drive tomorrow.

Ill keep you updated.

No discount tire direct is a website. I got them installed local. I tried getting them installed at Costco but they refused because the size was 4% larger width
Discount Tire Direct is the online retailer. Capitalization matters, but I should have understood "direct" used in the OP anyhow, but didn't, which was my bad.

At any rate, you probably should politely let the shop that installed them know about the slip-up.

Nice pictures and review! Thanks.
I will be needing new tires within the coming ~5k miles based on the wear trend I'm seeing on my factory tires. The Yokohama are near the top of my list after a lot of research.

A question - what prompted you to choose the larger size vs. the standard used from the factory? It might give it a slightly more aggressive look (which is cool), but don't you also see an impact on MPG and maybe some potential for rubbing in the wheel well?
I don't think they make that tire in the stock size for 18" wheels. They do in the 17", and I've been very pleased with them, but that's little help to you if you have 18s.

I have noticed a 1 to 2 MPG hit in fuel economy with the Geolanders (27K miles, ~2 years) vs. the OE Duelers (30K miles, ~3 years). I'm not sure if the 4% wider replacement available for 18" wheels would make a difference in addition to that, but if it does, it's probably not much.

Looking at tuswm's pictures, I would worry about rubbing on rough roads with the wheels turned, too; it would be good to hear about real-world rough road experience.

So I did take it on one gravel road so far and I have not heard any rubbing at all. There's about two finger with in all directions still I know it looks a little closer in the pictures. But again I've had no rubbing issues and I've tried to create them. I also know that other people with even bigger tires and took their stock mud guards off in that fix the problem. As far as miles per gallon I don't know yet but I also know that I did not calibrate my car for the slightly larger tires so I know it's going to be at least reading differently. I need to figure out how much different is reading and see if I can compensate for that with some basic calculations.

As for the on-road driving I have increase the air pressure too I think about 36 all around I don't have a super accurate gauge. My old OEM tires were worn all the way down to the wear bars so I can only compare it against those. I have noticed these tires seem to completely absorb the small bumps significantly better than the OEM tires but they don't feel as sporty. They just feel a little softer. They're definitely a different ride. They are definitely not any louder than my last tires. I have noticed especially in parking lots that the wheel turns easier.

If you have the stockings 18-inch wheels you cannot get this tire in oem size. You have to get it in the 235. But it looks great and I am having zero fitment issues

I have several. They all real slightly different especially when its warm out. I was also trying to fill the tires more while they were warm. Ill check again today before I drive anywhere.



Gas Milage
First you need to consider the difference in a worn tire, As it wears down it loses over 2%of its circumference. The new tires are over 2% larger circumference. so I have over a 4% difference in circumference now. Meaning that every time My car registers driving 20 miles One tires actually driving entire mile further.

Tires also get better mileage at the end of their life for 2 reasons. 1, less rotating mass, 2 less luggs creating wind resistance. They will also artificially read even higher comparatively due to the loss in circumference. Most people don't even notice the hit on mileage when they put on new tires because they are not paying close attention and looking for it.

That being said I have a 20 miles all highway drive that I do 4 times a day to take and pick up my son from sports. Depending on weather / speed/ AC I would get 32-38 MPG on that drive with the old tires. The last few nights I have been getting 29-34, 32-35 since I pumped up the tires.


I also reset my trip B odometer when I bought the tires so I could try and more accurately answer this question. I only have 4 days on the tires so far but its averaging 27.9 so far, my life time average for the car is 29.2

So its been all most a month.
1. current MPG stands at 27.8 ( right about what I expected see earlier post) I did average 32 on a 400 mile road trip.
2. Tire pressure made a big difference. The lateral performance on dry pavement was significantly improved by slightly increasing tire pressure.
3. I spent an hour driving in a down pour about a week ago, even at 70 MPH there wasn't even a hint of hydroplaning.
4. These are not touring tires, they dont feel like it. On dry pavement they are NOT as sporty are the stock tires.
5. I carpool with a guy who has AT tires on his jeep. We both agree that his are LOUD and mine sound like normal car tires.
6. I will be doing my first real soft roading this weekend, hopefully some minor mudding.

When I was out west I took my car up to obstruction point road in the national park. My stock tires were bald by then. I was worried about getting a flat. When I got up to the trail head I parked next to another outback that had a large rock in the tire. I actually tried to patch it for them. I put 3 plugs in it. I never did find out if it got them down.

The snow rating was one of the reasons I picked this tire. I have not had any snow yet. The stock tires were not that great. do you have anything to compare them with?

Still love the look.
They are great in the rain. Great.

MPG are the same.
I have settled on running slightly higher pressure to stiffen up the side wall and steering response. I think it is also helping with MPG. I kind of want to try running lower pressures again to see how they feel. They are a soft and complaint tire.

I have had them on grass and mud They did well on the mud but I would have been fine with regular tires. No real "test" yet. I bought these tires for 1 on road, 2 snow, 3 rare occasions soft roading, not off roading. I do occasionally go soft roading in west Virginia, occasionally drive on the beach, but if we get a snowy winter we do have a skiing family. The stock tires were crap in the snow.
I do have a long road trip planned for thanks giving where I will be able to take them 8 hours ( no traffic) to the beach, hopefully on the beach, and 8 hours home from the beach.
I also plan to go to Canada to Ski over new years. Last year it was a un plowed blizzard from central NY to Mt Trablent. The stock tires were so so bad.

I will have more to report back on as soon as we get some snow.

New member here...out of curiosity, I have read that the all terrain tire options for the 18-inch wheels are limited and most folks upsize, as you did, to the 235 Geolander GO-15s. In searching online, Yokohama does make a Geolander in the 225 size, but the aspect ratio is 55 rather than 60. Wouldn't this tire work fine on the stock 18-inch OB wheels too?

5000 mile TESTED mud and snow tropical storm rain up date

I have now driven the car in propper deep mud and deep snow. I took my car to a ford raptor off road driving event. I just drove my car to the starting point of the course through deep snow and deep soft mud. I never would have attempted this on stock tires. I also would not have attempted this with out 40 trucks with tow straps fighting over who would get to pull me out. I also got to have fun in the field ( staging area). It was the type of real world test where you have to scoop the mud off your roof when you are done.

These tires do EXACTLY what I bought them for. 90 % of dry road performance. night and day difference off road/soft road/ wet road/ snow performance with 97% fuel economy.

my worn stock tires did 29 mph gps MPH while car read 30. These tires due to size and not being worn did 31 GPS MPH when the car read 30 MPH. So I calculated that = real world gas milage would read 2 MPG lower than stock. I cam currently about 2.8 MPG lower. 29.3 vs 26.5 after 5000 miles. So I figuring I am with in 1 MPG real world MPG than the stock tires.

Awesome updates, thanks!

I'm very close to replacing my original tires, now at about 31k on my odometer. They are not totally done, but showing age and I have some time over the upcoming holidays to do this. I am just about sold on these tires. The only other questions I have are these:

- Do you have any issues with the TPMS using oversized tires?
- You've mentioned MPG changes, but I can't quite follow it. Sounds like a bit less MPG on the oversized tires, but very close?

Thanks,
Eric

OMG I would be SOO BUMMED. I wanted to wait till this week, having time, being a teacher. I guess things happen for a reason.

I have noticed something odd that I think I can attribute to these tires. By my house are a series of traffic circles. The pavement is polished smoothe. In the pouring rain I can not consistently induce throttle off over steer. Not possible with stock tires.

The car is So much better in the snow.

So I have a friend with a forester and blizzacks (dedicated snow tires) in the stock size. We went out for a hilly loop by my house with his car first. We both though that his car might have had slight better up hill grip on super packed down snow. we also though that my car may have done a little better on gravel with 8-10 inches of snow on it.

Both tires are like a million times better in snow than the stock tires.

Just an awesome thread. Thanks for all the info. Was considering a 2" lift on my 2018 limited but after reading about all the vibration issues some folks are having I've decided against it. Would have been nice on heavily rutted Outer Banks beaches. But I've had no real issues just running stock so far. I think these tires might give me the additional peace of mind I'm looking for while on the beach. That said, I have managed some VERY soft sand on the stock duelers.

Thanks for this post, I am about to go purchase the 235/60/R18 G015 Geolandar's for my 2018 Outback 2.5 limited with 18" OEM wheels. My wheels look different than your 18's, but I am hoping the fit will be the same. Will update with pictures and review later.
