First of all...I recomend getting rid of the 16.5 rims. Call a couple tire shops and get prices for similar tires in 16 and 16.5. You'll see what I'm talking about. I have a set of 16s that came off of late model chevy vans if I remember correctly. (I didn't scrounge them up...Longhornjeff gave them to me when he came for the
Ohio board meet ...stock hub caps even fit on them, added bonus!
Back to the question at hand, if you have the money, Michilins are pretty good. I have seen a set last over 100,000 miles on a dodge ram (the blazer kind...SUV before they were called that).
No joke...100K on the truck, and he never had to chainge a single tire. The POS truck died before needing a single tire.
They were dry rotted like a mo-fo, but they still had tread.
