You're tires look great with the stock wheels. I deleted the resonator on mine and it sounds awesome. Adds a deep throaty tone. Only cost me $30. 2 clamps and 18" exhaust pipe from Canadian tire.

That's pretty decent. I get 16 mpg all city. Could be better if there wasn't so much traffic.

I'm probably the odd man out but I like that my truck is really quiet. Though I did leaving it running once and only noticed when I couldn't find my keys to open my work locker. LOL

The weight of the tires won't kill the mileage as much as the increase in ride height and the rolling resistance of the wider tires. Wide tire = more contact with the road = more resistance to gravity and inertia. But that being said, as long as it looks cool who cares!!

A tune is in the mods list for me. Apparently 5 star does a good job on the 3.7 tunes.

Ok guys. I put on the Rancho Quicklift and achieved a 2" rise in the front and put 1" blocks in the back for a little bit of factory rake. Overall the truck looks great.

I settled on a tire. Considering the amount of highway miles I'll be putting on the truck, I went with the Nitto Dura Grapplers. Highway tread with an aggressive looking sidewall. 275/70r18's which will put me a little over 33.23"

I think this setup is the best compromise for an everyday driver who wants a little tougher stance and off-road appearance with the best on road qualities. I'll post some final pics when the tires arrive from Discount.
