With the one piece wheels that you have most shops can install the tires (provided you remove the runflats). I have found that most places wont touch a HUMMER, probably because they think you have the two piece wheels which require a special socket to seperate the halfs. And of course there are the runflats which again require special toos that only your dealer has. You will also find that CTIS scares shops, CTIS does not make a difference when doing tire work, it has a valve stem just like every other tire. If you want shoot me an email off list at
ssgharkness020147@yahoo.com and I can give you the names of a couple of shops in my area (about and hour and fifteen minutes from your house) that could put new tires on your truck.
