I have a question. I have a 2018 Ram 1500 and am looking to get some Nitto 420s 305/40 R22s. Will these fit on the truck if i level the lowered front with the higher rear

I have a question on my 2017 Ram 1500. , does anybody know the part numbers for the two different types of Park sensor bezels for the rear bumper? I ordered one part number and it came to me black. And flat, I need the silver or gray plastic ones and there's one flat one and one angled what so I need to part numbers.

You should ask this question here

Tire shops or online tire sellers will give you the info you need.

I have a 2009 ram 1500 with 20x9 rims, will 20x8 rims from a 2015 ram 1500 fit with no issues? What would be the difference and would it be noticeable?
Thanks.

I am thinking about new wheels and tires for my 2016 Crew Cab Laramie. It has 20" X 9" wide wheels. I see the offset listed above but I can't see anything on line that matches it. Tire Rack has 20mm. American Trucks lists different offsets but the closest is 18mm or 24mm. How close does this need to be? Is it better to go higher or lower if an exact match is not available and what could the complications be?

I have the factory raised ride height. I'm not sure how many inches that adds but it looks like I can get get bigger tires to work. Any lists of what would fit I can look at? I want to get more aggressive tires before the winter. I figured I might as well start looking now. The Goodyear's on it are close to done and there is nothing more embarrassing than a 4WD truck that can't get up a hill in the snow.

I would look into a 20x9 with 0 or +1 offset which will push the wheel out ¾". Are you looking to stay stock tire 275/60?

I want to go to a larger tire but I want to keep them inside the fenders and avoid clearance issues. It has factory raised ride height on the build sheet but I am not sure what that translates to in inches of lift.

275/65r20 nitto terra grappler g2s come in standard load not e-rating, so they are still relatively light. Its a 34x11 tire. I was gonna run it but went 305/55r20.
I would still run the 0 or +1 offset with that size, it will just look better and have no affects with fitment.
I run 20x9.5 -6 offset and the 305s, no level at the moment and no rub anywhere.

Theres alot of tire sizes that would work, but they are all load range e, if you dont need the E rating your better off with standard load for comfort and mpgs.

Smaller wheel size (17" preferred) will give you more small bump compliance vs a larger diameter with the same size tire, because there's more sidewall to flex.

Thank you for the excellent information. I have been looking into aftermarket wheels for my '21. Since it is a 4th Gen, presumably the information would be the same as up to '18,but does anyone out there know 100% for sure if this is the case?

On a side note, I found this website that can help you visualize it.

Wheel Offset Calculator

Use our wheel offset calculator to visualize the new tire position when changing wheel and tire sizes. Convert wheel offset and backspacing to calculate the correct setup for your vehicle.

tiresize.com

I remember seeing another one that would let you put in 2 different wheel/tire sizes and see the difference between the two as well. Just don't remember the URL.
