Tires and rims

So I'm looking to buy or trade for different rims and tires. I have 35x12.5x20 open country tires. I have 20 in rims but I'm told they are 10 wide so 20x10. The guy I was talking to said it won't hurt it the tire will just bubble around the rim. So if I go to a 20x12 rim than will my tires still fit? Or will I need different tires?
Really need help with all this and what can work and what cant work with bigger rims and tires.
Don't want to go any bigger than a 20 though.

I'm not a fan of tall tires, just to let you know where I'm coming from. Is your truck a 4wd? I presume it is, what gear are you running? Hopefully they are 4:56. If not then that is the first mod you want to do. Good luck..

With 37s yes I need a 4.56 and yes it is 4x4.
I don't even know the gearing just bought the truck 2 months ago. I was thinking either a Mosher or Eaton locker

I'm just not sure exactly who to install everything and what to look for if anything is broken. Or how to measure everything. Really don't want to pay 1100 for the labor and misc. Than another 600 for gears

You won't like my opinion, but if you seriously want to play with 37" off road tires then get a diesel and have at it. With the truck you have I wouldn't go over 33" tires and the 4:56 is still needed. With the 37's the only thing you will achieve is a dangerous vehicle to drive not even talking about stopping as you have nowhere near enough brake or axle. The gears will most likely run you around $2500 for both axles. Good luck.. Do your research and you will see what I'm talking about.

That's big as I would recommend, but maybe the off road crowd will chime in with some input. Remember I'm a street guy. Those big wheels take up a lot of HP....

Is that all it loses? Of course torque goes down as well but would 37s hurt the truck as a whole if the gear was changed to a 4.56?

The big tires will affect your braking ability. Comparing 31" tall tires with 37". The 37's are 16% taller. If you weigh 9000lbs with the 31" tire, the 37" tire will feel like the truck weighs 10,440lbs as far as acceleration and deceleration goes. Plus your gas mileage will dump due to the lack of mechanically advantage of the gearing and the rotating mass that has significantly increase due to tire weight which is also unsprung weight and finally there is considerably more wind being trapped under the truck to drag it down even further. These conclusions are all based on voodoo math. But in reality you may not even beable to lockup the wheels at 55mph for an emergency stop. As far as being a sleeper I think not, too much going against being quick or fast. As a further example check the speed rating on the tires you want. They are probably more suitable for farm equipment than racing. But trust me I am only trying to discourage you from going in an counter productive direction and certainly not from modifying the truck. Bottom line is it's your truck and it is up to you what you want. Good luck....

Is

What if it wasn't a full off road tire. Maybe something like Mickey Thompsons all terrain
