Geolandar A/T-S

I was considering installing Yokohama Geolandar A/T-S tires on my '08 GV. Does anyone have experience with them?

They seem to be a good combination of highway/offroad/snow tire. The stock size is 225/65-R17. I was considering going one size bigger, 235/65-R17. I know the speedometer would be off about 1.8%, which should put it right on since it currently reads fast. The other issue I had was the 235 tire has a higher load rating which may make it a stiffer tire and which may increase road noise and provide a rougher ride (which I don't want).

Opinions?

Geolanders are good tires. I've read alot of good reviews of them.

You will get road noise with any AT tire. But you'll get used to it in a week or so.

235/65 - there are two sides here - higher load rating -> stiffer ride, but bigger size gives you more rubber between the tire and the road which might compensate for the stiffness. Depens on how much higher the load rating is. 255-70-16 Nokian Vativas I had were a lot softer.

You should consider Nokian Vativas AT. I chose them over the Geolanders. You would be amazed how good they are in a winter. If I were to get AT tire I would buy them again.

I had problems

I put Geolander A/T S on my 2007 GV and replaced them after about 25,000km. After complaining to my Suzuki dealer about the factory geolanders wearing unevenly and having them do nothing, i had to talk to a Yokohama Rep, who gave me pro-rated warranty. I installed the A/T S tires and they weared unevenly as well. As these tires add a significant amount of road noise already, the uneven wear made the noise unbearable. I finally went in to a reputable alignment shop who immediately found a service bulletin(which my SUZUKI dealer did not find) correcting the GV's alignment(apparently this is a major problem). When i asked about Yokohama's tires, they were hesitant to comment, buit finally revealed that they had seen many, many sets of yokohama tires with irregular wear, regardless of the alginment. I immediately removed the Yokohama's and bought Goodyear Fortera Silent Armor. Much quieter and no irregular wear.

Congratulations takeitallapart, on getting your GV's alignment sorted out. Besides preserving your tires, that will increase mileage, make the handling much safer and reduce wear on the drive train.

I just put on our winter wheels and removed our set of rims with the original Yokohama's. They now have almost 40,000km on them, and have 7/32" tread depth remaining. The tread depth varies by less than 1mm over all surfaces of all four tires. We've never had an alignment done, and have rotated the wheels about every 5000km. The tires are starting to wear through the bottom of some of the tread pattern, and so are no good for winter use now.

The great tire search goes on...

At first, I didn't even consider Michlens since they are expensive, but it appears that I can get the Michelin LTX A/T 2 for almost the same price as the Geolanders or the Toyo Open Country.

The reviews are very good for this tire. Does anyone have any first hand experience with the Michelin LTX A/T 2?

I used to avoid expensive tires. However I've come to believe that cheap tires cost more per unit of distance driven because they don't wear as well and they're more likely to get damaged. A damaged tire often means replacing the whole set. Meanwhile, better tires tend to provide better handling, better mileage, better traction, and less noise. There will be exceptions, but the best tires provide value beyond the price proportion to cheaper ones.

One thing to check when buying tires is tread depth. It varies a lot, and so will the miles you'll get out of them. Of course, in general deeper tread means more weight and less precise handling until they wear down to the depth of shallower tires. tirerack lists tread depth as a specification.

I have changed from my stock from 225/65/16R (Bridgestone) to 225/70/16R (Yokohama AT-S) and immediately I felt my GV was floating after the changed:mad:. Before that my GV was having a very saloon car liked sort of handling but after the changed of 1 size rubber taller, I can no longer drive as fast around bends as I would normally do:p. The floating feeling is scary:eek:! When I was driving my former SUV the Honda CRV, I do not have this problem even when I had up graded the rim from a 15 inch to a 16 inch rim and also used other size rubber on that rim:huh:.

I thought 225/70R16 was the OEM size.

Regardless, I doubt that small change would make that much difference. However, different tires certainly do feel different; it's most likely you're just not liking the feeling of the Yoko's compared to the BS's. And as geevee says, deep brand-new tread, especially on soft compound tires, can make handling feel vague.

Down here in Singapore due to the way our road tax is base upon:mad:. The bigger C.C car you have then you will have to pay a much higher road tax:p. Thus, most of the GV in Singapore are the 2L 2WD version:lol:. There are only a handful of the 2.7L 4WD & 2l 4WD versions on our shore:D. Then came the 2.4L version which just got onto our shore about 1 year back:).
As for the rubber size. Mine is the 2L 4WD version which came with 225/65/16R but because I was bitten by the off road bugs (Poisonous off-road bugs from SUVec.org.sg) which I later changed to 1 size higher which is the 225/70/16R:lol:. Then there was this sudden change in my GV handling:mad:. The slightly higher but softer side wall of YOKOHAMA AT-S have made my GV very floaty when making turns on the tarmac roads:huh:.

Well I, just had the Michelin LTX AT2 P235/65R17 installed. With the mail in rebate Michelin is offering, it was pretty much the same price as the other tires I looked at (Toyo, Yokohama, etc.). Check them out here:
LTX® A/T2: Light Truck Tires: MICHELIN® Automotive Tires: Michelin Tires

The stock tires I had where the Yokohama Geolander G93B. As my tire guy stated, they are "OEM starter" tires. After 31,000kms, the tires where down to the wear bars on all four tires. I could have gotten a couple more months out of them in the summer, but with snow coming, they would not be acceptable. The OEM Geolanders where suprisingly good in the mud and snow. With the new tires I figure the GV will be unstoppable.

First Impressions of the LTX AT2:
I got one size larger, the 235 vs the stock 225 so they run a GPS confirmed 3% slower. No big deal. The have some serious meat on the tread and look fairly aggressive, but not over the top. Hopefuly I can get some seroius mileage out of them since they are a premium tire.

How do they ride? Fantastic. The ride is significantly smoother. They are an all terrain tire, so they must be noisy right? Wrong. I think they are quieter than the all-season Geolanders. Not just a little quieter, but much quieter on the highway.

Downside? They do not handle as crisp as the Geolanders. The GV has lost it's sports car feel, but I can live with it. The handling may improve once the tires wear in a little. It is amazing how tires can transform a car. The GV now has a much more luxurious ride, you don't feel every bump in the road.

Once I get a few miles on them, I will report back on how they perform under various conditions (snow, mud, rain etc.). So far they are living up to the marketing claims so I expect them to perform very well.

Good choice!

Larger size also contributes to improved ride, and softens the handling.

Do you mind sharing the price?

I did not feel ANY change in road handling when I changed to my Pirelli tires.

I have however, after 10.000km, noticed an increased rolling noise, but I consider this to be normal with A/T tires.

I wonder if people consider changing the tire pressure, when changing to different size tires. The larger the tire, the bigger the handling difference when at different pressures.

Mine gets very floaty when I am below 30psi, feel "normal" at around 35, and sporty at 40.

I can easily feel the difference between 35 and 38 psi, which is why I stopped checking my pressure. I simply feel when I need to pressure up a bit.

Oh, and anyone considering changes, should give the new tires time to wear in. You do not get ANY real performance out of a brand new tire. They are always greasy and slippery, so they need to be driven and ride in. After 1 - 2000km, then its another story.

Good point about new tires being slippery. I will try increasing the tire pressure to see how it effects handling. The tire guys put in 32psi, but the tire is rated for 45psi, so next I will try 40psi after they have a few km's on them.
