Big tires on stock 22s

[Morenar]

I swapped my stock tires for Nitto Ridge Grapplers (285/55R22). I like they way they look, are pretty quiet, does well is rain, and seemed to have good traction in the snow last winter (but we also didn’t get a lot of snow last year). I have a 2020 1500 Laramie night edition with air suspension. The only rubbing happens on the front tires at ”Normal” or lower heights and when turning the wheel all the way to either extremes, which I really never do.

What tire pressure have you been running?

Not the person you were asking, but I have the 285/55R22 AT3 and Discount tire told me 45 all around, but I find 44 in the front and 41 in the rear makes better contact

Ok I currently have the same size but in a Mickey Thompson Baja boss AT and running them all at 40. That seems to work well so far.

I put on 325/50/22 Toyo Open Country ATIII and had rub on the frame rail at full lock. It wasn't much of a big deal, but did eventually push me to a lift and new rims.
Here's a before and after.

Truck looks awesome.

I’ve been running 45 psi, but now that winter has set in, it’s more in the low 40s because of the cold. Seems like a good level in terms of comfort. I’ve never bother to do one of those chalk tests to look at the patch pattern, though.

For anyone running a larger tire size than stock 285 / 45 R22, are you doing anything about the different speedometer result? I saw somewhere in a different post in this forum that there's a device that plugs into the ODB II port specific for the Ram allowing you to put in the new tire size and it adjusts the speedometer readout. Just curious. Some of these tire sizes can be off by 2 to 4 mph depending on the speed you'd be going with the original tire. Deciding between Falken Wildpeak AT3W (backordered at Discount Tire locally), Toyo Open Country AT3, and Nitto Terra Grappler G2 as well as what tire size. 305 / 45 R22 seems like it works and gives a nice stance and only rubs at full lock. I've seen some drill into the plastic wheel well liner and zip tie it back to address the location of the rubs for the front tires. Seems like the only issue.

After reviewing several forum threads (thank you all), I installed Toyo Open Country ATIII's size 285/55R22 on my '21 Limited. They only rubbed at full turn of the steering wheel, and mainly in the lowest ride height. So I took a pair of scissors and trimmed a few small pieces of flimsy plastic in the front wheel wells. It took 10 minutes. No more rubbing, except at full crank in exit/entry level (which I rarely use). I did not do anything else to the truck (no levelling, no lift, no spacers). The tires are great. Only slightly louder than the stock tires. The speedometer now reads about 3-4 mph lower than actual at highway speed. Photos are at normal ride height. I've put about 500 miles on them so far, including highway and some limited off-road.

That looks great. I had the AT3 285/50/22’s, and if I were to do it again, I’d get the 285/55 instead.

They E load range. How’s the ride stiffer for sure right? I juts heard to many people say you feel every imperfection on the road due to the E load 10 ply tires stiffer walls.

People have wild imaginations. I've had them on little 2 door jeeps (not the luxury yachts they call jeeps today) and never noticed the difference.

Probably because everything is rough on those

But yeah, there's really not that much of a difference
