Hi just bought by new H3 the dealer had upgraded to 285/50/20 Kumho tires that look great but it seems to wander on the road at highway speeds.  It is not terrible but kinda of annoying any suggestions?

Thanks

First, Welcome aboard.  Second, If the tires are causing issues and you just bought your Hummer have your dealer switch back to the stock tires.  I don't notice any wandering at highway speeds with stock tires.  Third, Let me be the first to say:

LOL.  Ok I really want to keep the upgraded tire and wheel package but I want my H3 to quit wandering also.  I will get some pic uploaded soon.


Thanks

Sorry I didn't realize that it was a tire/wheel package.  I would definitely have the dealer take a look at it.

You should do as Rutdogg suggests and have dealer look at it, but be prepared to look at other options.  Tires can have a huge effect on ride and handling, and sometimes a particular manufacturer or design does not perform how it should, or how you expect it.  I have had situations on vehicles where, as you described, the vehicle wanders after a new set of different tires were installed.  After complaining to the store I purchased from, and much experimentation such as trying another set of same model, rebalancing, checking alignment, etc, found that some tires just don't perform well on some cars, or at least, they introduce some ride aspect that you do not like.  The type of rubber, the rigidity of the sidewall, the tread design, the quality, and then the vehicle itself all contribute to the final ride experence.  Good Luck, and lets see some pics

I have noticed that with high winds 25-30+ and my 33" tires that I get blown about the road a bit. Just like my old jeeper used to. Might be that, were there any winds?

Mine wonders when there is alot of wind.  I don't think that's out of the ordinary.

Between the "tire tracks" on the freeway and wind I'd say this is pretty normal.  Anytime you don't fit in the "tracks" you're going to end up dancing left and right on the ridges .. All the vehicles I've had in the last 5-6 years have done it, you get used to it after a while.

One thing that you did not mention in your post was what you were driving before you bought the Hummer.  As HummBob has so eloquently explained, it is basically a brick on wheels. And a brick that has a lot of surface area to catch any little gust of wind. Granted, the wide track of the aftermarket tires probably don't help any. But truth be told, its probably a combination of all the afore mentioned posts. Add that to being used to driving a more aerodynamic vehicle and voile, there you have it: A Hummer.

Enjoy!
