Re: Trailering a tahoe Q7 -Tire wear issues
I rented a cabin last year for vacation, and launched my boat and put it into the boat house. I towed the trailer back to the cabin, and had the first opportunity to really inspect the trailer (boatless) in a year (I usually launch the boat, while my wife backs/pulls the trailer out and parks, so I rarely get to see it with the boat off). I was pretty amazed/dismayed at how much wear that the back axle tires had. Of course with a tandem trailer, one axle's tires turn, and the others skid, when turning.
I replaced the bias tires (dangerous anyway) with Durun (bought on eBay. great online reviews, and a good price) steel belted radials, and they are wearing better than the bias ply tires, are safer, and they tow much better. Less rolling resistance as well. I believe that they were $50 or so each, shipped, and cost about $10 each to mount.
My advice is to install steel radials, inflate them to near max pressure (my max is 50psi, and I keep them at 47 to allow for air expansion when warm), and most importantly, make sure that your trailer is as level as possible when connected to your tow vehicle. That is very important. With a trailer that is way off of level, one set of tires will be handling too much weight, and will wear faster, not to mention possible overheat/blow.
I also bought the SecuTire tire pressure monitoring kit (no digital display, but it alarms when one tire falls below threshold pressures) just for peace of mind. Wireless kit that installs on the valve stems, with a receiver unit that plugs into the 12v power outlet in my truck. I believe that it was $60 on eBay. Nice peace of mind.
