Right now I have the stock LT285/60R20 tires on my 2020 Ram Laramie 3500 SB SRW with the all black 20" rims that come with the night edition.
I tow a 15K fifth wheel and with my current truck/trailer setup I cannot get level- the front of the trailer sits high, requiring me to drive with it at "Alt Trailer height" which still does not bring it to level . I've lowered my hitch setup as low as it will go, and need to get another two inches to level the fiver and give me piece of mind and make the trailer axles and springs happier. The trailer has 15 inch wheels on two axles and I cannot size them up to 16 inch- not enough clearance under the trailer that could cause bigger wheels/tires to rub on the trailer underbelly if I hit bumps. It's a Vanleigh Pinecrest. The other problem is that the high front makes the rear levelling legs sit closer to the pavement and I have dragged them repeatedly on driveways and had the footpad pop off three times. And I cannot raise the levelers, they are mounted as high as they can go.
So my next step is to think about dropping tire/wheel sizes. I didn't ask for the 20s , they came on the truck as part of the total package. The tires are starting to show their age so with replacement in mind I am considering switching down to 18 inch rims and tires with the idea that I might gain an inch or two.
So for those of you who are towing trailers with your 3500 (and I run mine with about 400 lbs remaining payload capacity when hitched and loaded)...
If you have 18 inch tires and wheels what is the total height of tire and wheel? I'd like to compare to what I have now and see if it is an option worth looking into.
