Hello all
When I bought by 2020 Laramie there were certain options I had to have and a few I didn't want. One of those items I really didn't want are 22" wheels. While I like the look of the stock 22s i just don't like the tires and there are very few options should i want to go a size taller 285-50 vs the stock 285-45. I like the Toyo AT3s but they are on back order with no restock date and I want to get rid of the current tires before winter.
I keep finding the aluminum Rebel wheels for sale and I really like them (I like OEM stuff). Tires are much cheaper for the 18" rim and many options.
Question for this group is will I have issues with either TPM or speedometer by changing from 22-18? Diameter of the tires remains the same.

I changed from 22 to 18 for winter. OEM tradesman wheels. No speedo issues at all…….TPMS picked up right away and all is good. All safety things, adaptive cruise control etc work as expected.

As said previously, as long as the overall diameter of the tires stays the same, your speedo should stay accurate.

Something else to mention; even though you did say you like the OEM stuff and if you do end up getting a set of used Rebel wheels, you might want to find out beforehand what type of wheel sensors you have. I’m pretty sure the sensors in your wheels are probably the same as the later-year 4th-GENs and totally not like the wheel sensors that was in my old 08 where the valve stem was rigid and was part of the sensor that had a curve in it to match the profile of the wheel but, it doesn’t hurt to check. Who knows, you might even be able to reuse your same sensors with your new wheels.

You can reuse your factory sensors on another set of wheels. But it does require a rebuild for each sensor. Tires shops charge a minimal fee per sensor to do this. Or you can buy new sensors if you want to keep the sensors with the original wheels (like I did). And like corneileous said, as long as the tire diameter remains the same as stock, your speedo and odometer will be accurate. There are online tire size calculators for determining tire diameter based on tire size. I use this one...

Being that it’s that new of a truck, I don’t see why you would need a rebuild kit for the sensors unless perhaps since the valve stem seats inside the stem hole just like a regular valve stem, you may not be able to remove the valve stem without destroying it.

At least one thing about it though, if this is what the tire pressure sensors look like then you wouldn’t have to worry about replacing them for ones that are made for an 18 inch wheel like the sensors are, I’m pretty sure, in the old third gens.

Age isn't the issue. It normally damages or destroys the rubber valve stem when they remove them. The rebuild kit is a new rubber section.

They don't have different sensors for different size wheels, at least for 5th gens. He can use the sensors from his factory 22's in 18's with no issues. I have no idea about 3rd gen sensors so I can't speak for those.

Thanks all for the input. Just located a set of takeoffs with tires. Hope to pick them up this week and mount them this weekend.
The new set has the sensors so I should be good.

I don’t know, it might be in a couple years once I get the truck paid for but if I ever get new wheels, I’ve been contemplating the idea of dropping down to maybe an 18 being that I’ve been told they will ride smoother than the 20s. Although I have never driven one or even ridden in the same truck as mine that was equipped with the coil ride suspension but I’m almost convinced that that air ride of mine probably makes my truck ride a little stiffer than it would with conventional coil springs just because of how my air ride is progressive to the amount of weight that it is carrying.

My concern going to the 18s is that they are a 10 Ply (Load Range E) tire which weigh a lot more and will be stiffer. I can always go back to the 22s if i don’t like them. I will try and update the thread to share my experience if interested

Yeah, there is that but don’t let that spoil your new wheels because you can get 18s probably in that size that aren’t a 10 ply tire. Depending on how good of shape those rebel tires are in, you might be able to sell them for quite a bit of money and if you like the wheels, you could probably even sell your original 22s together or separate from your current tires depending on how good of shape those are in. I don’t know how many miles are on your new rebel tires or your current tires but when I got rid of the Goodyear SRA 20 inch tires that came brand new on my truck, granted, they only had about maybe 1600 miles on them but I got rid of them for almost 400 bucks for the set.
