@toobladink I'm late to the party, but OSPHO is another product you might look into. I'd trust 410Fortune's Permatex though, he's been doing this.
Tires, only ever LT. It's a light truck, they make tires for these for a reason. It's a truck and it's designed to be used like a truck, give it tires designed to be used by a truck. You'll thank yourself for spending the extra $100-500 it costs for a proper set of tires (and a matching spare, please tell me you're getting a matching spare) when it DOESN'T blow out, and you save all the time and money you would have spent on replacing a tire you shouldn't have bought in the first place. The miniscule saving is NOT worth the risk.
For the record... I've got 4 vehicles, all with matching spare wheels and tires, three of which are off-road trucks with A/T or M/T LT tires. I have never worked more than one job concurrently. You have no excuse to cheap out on tires!
And I have no excuse to cheap out on brakes. Following your lead and again 410Fortune's, I ordered up the Power Stop K1861-36 (Z36 Truck & Tow). If you like it on the 4-door, I'll trust it for my 2-door.
