    Hello folks,

    Long time lurker, first time poster here. I’ve got a 2024 Tundra 1794 Edition with the TRD Off-Road package. The truck has under 17k miles, but my alignment was way off and it chewed up one of my tires—so I’m in the market for replacements.

    I’m torn between two options:

    • Stick with the stock 20" wheels and get true all-terrain tires (up to 34").

    • Swap to 17" or 18" wheels and run larger tires (up to 34") without suspension upgrades.
    This truck is my daily driver and mostly a pavement princess, but I’d like something a bit more capable and with a better ride. I’d love to hear your thoughts on:

    • Benefits of downsizing wheels vs. staying with OEM 20s.

    • Tire models/sizes that work well for my use case.

    Downsizing wheel size will net you larger sidewalls, which traditionally is associated with a softer ride.

    With a correct offset you can run 295/70/18 in C rating in stock suspension OR you can do 275/65/20 (34") or 285/60/20 (33.5") both in SL. Going with the 18" wheels will cost up an extra $1k or so. These tires cost about the same.

    I'm not a fan of 20's, especially for something with "Off Road" in it's name, regardless of what one actually uses it for.
    Full disclosure: my '24 Limited TRD Off Road is also my DD and primarily a pavement princess, but I do tow fairly heavy every so often. (And hope to do more in the future.)
    I went "all the way" to a 35" tire (285/75/18) with just a level lift in front.
    The unfortunate downside to a 35" is that they are not available in a "C" load or an "XL" load range. (There might be a "D" out there.)
    Which leaves you with an "E" load, a relatively heavy, 10 ply tire.
    The minor decrease in ride quality for me was worth it. Going from 20's to 18's AND upsizing overall diameter gained me a LOT of sidewall.
    More sidewall = more tire compliance = softer ride.

    If you don't mind the additional expense of new wheels as well as tires, go with the 17's or 18's.
    295/70/18 (34") was my go to size before I decided on 35's.
    Go with the lightest wheels you can afford. (Check out FN's group buy going on right now; great wheels, light and affordable.)
