Nice thread! It's hard to find trucks like mine to steal ideas from. Even though my silverado is a 2008 4wd half ton I'm getting some valuable information here. My next upgrade will probably be tires. I currently have stock 265/65/18's on my truck. Does the tire your running come in +1 OEM size for my 18" wheel that you know of? I've been shopping for tires and I find it hard to find many options in a 18" wheel. I guess I should've thought about that when I bought my truck
Chevy has been getting really bad lately at putting odd ball sized wheels on their trucks. If it's not diameter, then they use weird back spacing. This really hampers your selection of aftermarket wheels and, in turn, tires. They still haven't figured out that there's not a big selection of HD tires in 17" and 18" diameter. The ones that are avialable are $$. Unless they are going to go to 19.5's, which would also be cost prohibitive due to tire prices, they should stick with 16's and normal back spacing on HD trucks. Of course there are a lot of folks out there that go for the big bling bling wheels and tires, but that's not practical.
I just realized yours is a half ton, but the same applies. Put a wheel on a 4x4 truck from the factory that has a large tire selection available. Or, press the tire manufacturers to expand there size offerings. Very frustrating.
I really look forward to a long term evaluation on the Goodyear MTR's from Outback. He has a great first impression. Now I'd like to see how long they last.
