Understanding how to pick out the right size Tires, Rims and wheels

What happens here

The discussion shifts to tire and wheel setups that require significant vehicle modifications. A 35-inch tire on a 20-inch wheel is introduced, noted as typically requiring a minimum 4-inch lift kit for a Jeep or 1500-series pickup truck. Moving to even larger options, a 37-inch tire on a 22-inch wheel is shown, demanding a minimum 4-inch lift, fender modifications (such as cutting or replacing), and likely re-gearing of the vehicle's differentials to maintain performance. The hosts explain that these larger sizes dramatically increase weight and stress on suspension and drivetrain components.

Goal: Learn about tire and wheel sizes that require significant vehicle modifications.

Tools and materials

  • 35-inch Tire with 20-inch Wheel — Example of a setup requiring a 4-inch lift
  • 37-inch Tire with 22-inch Wheel — Example of a setup requiring significant modifications including lift, fender work, and re-gearing
  • Blue Jeep Jeep — Demonstration vehicle for modified setups
  • Measuring Tape — Demonstrating wheel diameter

is this is all fairly factory sizing. Everything that's going to fit without really messing up your truck, your Jeep, too bad. Okay. So, and then from this way forward, we're going to be modifying. Yeah, we're modifying all sorts of fun stuff. So, we'll start off. This is the 351 12 1/2. This is your typical 4-in lift kit minimum to fit it on, you know, a Jeep. 6-in lift kit to fit it on a 1500 pickup truck. And what size rim do we have on this one? This one's on a 20. A 20. Okay. And so here we've got a 22 in rim. We got a 22, but this is a 37. 37. So this one, you start getting into this size is when you're going to on a smaller vehicle like the Jeep, thinking about uh, you know, modifying things. So that's why we're putting the fenders on on yours. We've also got to put a 4-in lift in minimum. Yep. Minimum 4in lift. And at this size is when you start thinking about regearing heavily thinking about especially if you're going to actually use it for what it's meant for. Exactly. Then you're going to rege. Yeah. Well, if you I mean if you're going to take the Jeep off on the trail anyway, regear it from the factory. That thing is designed for highway cruising because just the tire alone, just just rolling down the road, this tire alone is going to be creating extra torque. And where I mean this thing's heavy. Yeah. Yeah, you know, you compare this just the size difference from your factory Jeep wheel to this new one. You're talking an extra 100 lb of rolling mass on all four corners. So, you know, brake wear, suspension wear. So, that's where the lift kits come in with the beefier components, things of that nature. Not to mention, you try putting this on with your factory fenders, you're going to be you're not turning. It may fit like you may be able to get it in the in the hole in the hole. It's the turning that that is the issue. It's the turning. So, you're going to end up cutting the cowl and modifying a lot of the body components just to get something like this. Yep. Where if you go down to We don't have a 33 in here. We've got the 32, right? Well, I mean, it's a it's close enough to a 33. This you can get away with, but you can w Can you widen this this tire out to this? What is this one? So, this is a 12 1/2 wide. So, you can do a 33 12 1/2. Okay. Um on say Well, on the Jeep, you can do it on a leveling kit. a truck, you're gonna want to go up to three and a half inch, 4 inch lift. Okay, guys. We talked about clearance issues and we're going to show…
