Well, I don't have a truck yet, but I've been buying stuff anyway because my wife "technically" never said I couldn't...
My useless information for the mob today:
I was curious about the exact weight of the Nitto Recon 35x12.5R20's that I ordered (bought those and the Vossen HF6-4's 20x10), so I threw them on the scale. They came in at 69 (giggity) lbs a piece, so about 7lbs over stock. The Vossens 20x10's weigh 35lbs, so all together about 12lbs per wheel over stock weight (I believe the stock rims are right at 30lbs if I'm not mistaken).
This may not have helped you, but please know that it has certainly helped me stay occupied while fantasizing about the truck I'll someday have in my garage. Until then, I'll continue to make posts like this and include pictures of new things I accumulate...
...as well as random pictures of interesting people at the airport.
