Needing some help

[ChristopherClaySr]

I just got a RAM 1500 Big Horn 2019. I'm looking to get a wheel and tire package running Nitto Ridge Grapplers for a smooth ride with a little lift without any rubbing. Also I don't want any interference with the speedometer or the TMPS. I'm new to the world of full sized trucks and need all the help I can get. So any and all would be appreciated. Also I was looking at some Chrome TUFF Wheels 22's they look pretty sweet and would look awesome on the "Big Horn".

If you change the diameter of your tire/wheel combination you will have some speedometer error. That's just how it is. You can correct that using Alfa OBD tools.

You did not mention what size tires & wheels you want to go to. However, you can get some additional clearance up front by installing some adjustable shocks. Bilstein 5100 shocks come to mind. You don't necessarily need a lift to get that clearance.

Lastly, be mindful of what wheel width and offsets you need to avoid clearance problems.

Good luck with the upgrade.

If you want a smooth ride. Why are you looking at 22" wheels? the more wheel you have. The less tire you have.

The less tire you have, the harder the ride will be.

Why not just look to see if the stock size tire is available in the nitto ridge grappler? If you keep the same size diameter, it wont affect your speedo.

If you want bigger tires then by nature it will make the speedo off. As you have increased the overall diameter of the wheel/tire.

To Maddog and LeesEvoX, I thank you both so very much for your input and your information. I have an old military mentor of mine who has the same truck and his wheel and tire package is 33x12.5 x20 "Nitto Ridge Grapplers/ MottoFab -24 offset. So after seeing his I'd like the same but was a little caught in between running 20's or 22's. Also I was looking for these Chrome Tuff wheels here.

To add to what MADDOG said, wheel size is unimportant as far as speedometer calibration goes. It's the outer circumference of the tire that matters. How many rotations it takes for the tire to roll a given distance. Of course, tire diameter is directly related to circumference. But my point is that wheel diameter doesn't matter. As long as the tire circumference stays the same, the speedometer won't need to be adjusted. There are online tire size calculators you can use to figure out the numbers if you don't want to do the maths. They also give you an idea of how much your speedometer will be affected when changing from stock tire sizes.
