I lift my gmc sierra and i got bigger wheels. It became so heavey! Can't move?

I have a 3500HD sierra 2008 6.0 vortec, i lift the car 8inchs and got bigger tires, it became so heavy, like seriously i can't use the 6th gear on 60mph, i have to keep it on 5th or less. Its so slow, make sense the tires are heavy, but its not that big its still 17 size of the rims, i've seen people in california has dodge, chevy, fords with alot bigger wheels and lifted more than 20inch, and they drive it daily. I'm i missjng something? Couldit be the diff ratio size? Trans program? Cause the truck is stock at the monent, just lifted and bigger tires

Its not just me, most my friends here have american trucks and lifted and have the same problem, workshops here are useless. Any tips?

Modeling Agencies for teens?

My name is Lee and i'm an actor but recently I started modeling and love it. I'm in the process of trying to build my portfolio so my friends that take photography are taking some shots of me and stuff but i'm also gonna try to get a professional photographer to get some shots as well. But anyway I want to submit to an agency once I get some good shots But I know I don't have that much experience to be a Ford or Wilhelmina model yet. So are there any agencies that would take me. I just want one where I could build good experience. It'd be the dream to be in an American Eagle campaign!

Should I get a fuel efficient V6 sedan?

I'm a 16 year old guy and I want some type of vehicle. The price of gas is going down. I want a Ford SUV or truck but, then I started thinking how much money I'd save by getting a car. Should I get a fuel efficient V6 car? I'm not going with a 4-Cylinder. V6 or V8. I'm not looking for fast but, I don't want a car that struggles to get going. The only thing I worry about is how well it will handle in winter and whether or not I'll get stuck. A car I was thinking of was a Ford Contour/Mercury Mistique. Would that be a good car?

Added (1). I will only EVER own a V6 or V8. Who said anything about RWD? I'm not looking for some tiny car that I don't fit in. Not happening.

Added (2). I'm not looking for some car to modify and waste my money. That's pointless.

93 ford tempo cabin lights, panel lights, and radio will not work?

I own a 1993 ford tempo. Everything usually works on it, but today, when I went for a drive, the radio, the interior lights, and panel lights did not come on. Everything else works fine. I have checked the fuses, and the connections on the battery, but they still do not work, can anyone help?
