    Got my 2021 TRD back in November and I love the truck. One of the things I’ve noticed though, is I can really feel the road vibrations on many of our bumpy Southern California freeways a lot more than any of the other 4 Toyota pickups I’ve had in the past. Often times the truck just really shakes bad from the imperfections in the road at freeways speeds. I’ll look down and my whole body is vibrating like I’m operating a jackhammer, haha. I realize it’s a truck and don’t expect it (or want it) to ride like a Caddy, but my other Toyota pickups didn’t vibrate anywhere near this much. It definitely depends on the freeway, as it’ll vibrate on particular sections of different freeways, and ride smooth on others at the same speeds.

    Anyway, was wondering what or if anyone else has done to make this better? Is it because the OR suspension is so soft? Stiffer shocks? Do the TRD Sport models do this too? I don’t want to put a few hundred lbs. of weight in the back at all times to dampen the vibes. Not a huge deal, but if I could smooth it out to ride like every other pickup I’ve owned on the freeway, I would like that. Thx.

    Mine tacoma sorta felt the same way when i had no time on it. Don't know for sure, but i changed from the stock firestones all season to some goodyear a/t tires, and it was a little better as far as ride compliance. Now with 7k miles its a different truck....ride much smoother with 0 road noise to the driver. Dealer had told me these suspensions need about 5k miles to break-in. You don't want to change anything until you give them that much. Here i was back last summer complaining how bad i thought the shocks, and springs were. Imo, i think they were right.

    I would think the same, except my ‘98 Tacoma didn’t do it on the the same sections. Neither did my wife’s ‘06 Tundra that I sold right after buying this new Tacoma.

    I find my 2020 Sport to be pretty bumpy. Does not absorb the bumps as well as other vehicles ive owned. Have you checked the tire pressure yourself? My spec is 29psi all around and I found the dealer had set them to 40psi. I dropped it down and ride was much better. Especially on snow and ice.

    Hopefully my suspension will settle out too then. I changed the stock tires to Falken Wildpeaks at 600 miles, but I had the same vibes with both sets of tires.

    My pressure always reads between about 35 and 37 PSI on my dash (depending on the outside temperature), and my manual gauge also read 35 on all tires when I checked them a couple weeks ago.

    What pressure does your door sticker state? I would try dropping it and see what happens.

    I’m wondering if stiffer shocks would help, or possibly make this particular type of vibration even worse? I would think stiffer shocks would dampen it more and reduce the vibes, but wondering if stiffer might actually transfer the vibes to the cab even more?? I dunno.

    If you are still running the stock GY’s than you should be running 30 psi.

    I’m running (SL) 265/75r16 Falken Wildpeaks. But I noticed the same vibes the 2nd day I had the truck, still on the stock GYs at the pressure set by the factory.

    The door sticker says 30 PSI. Ironically, my TPMS is set to give the low pressure warning at 29 PSI. So basically I would get the warning message pretty much everyday if I set the pressure to the door sticker. I actually tried running 30 when I first got the Wildpeaks (which is how I found out my warning goes off at 29), and it didn’t make a difference in vibrations. I’m pretty confident it’s the suspension and not the 2 different sets of tires I’ve had at different pressures.

    Ok, so I put about 200 lb. or so of stuff over the rear axel and drove it just now on the freeway where I know it was vibrating before and it rode noticeably smoother now. I don’t roll with a heavy load in the bed probably 80-90% of the time I drive the truck, so short of always carrying extra dead weight and making my MPGs go down, what does TW suggest? New shocks? Any suggestions of brand/type? Or just accept it and pretend I’m jackhammering a sidewalk whenever I’m on the freeway, lol?

    Just picked up my 21 TRD OR last month and have been experiencing the same vibrations on SoCal freeways. I’ve noticed it only does it on concrete freeways, but when it does I do feel like I’m jackhammering. Running 38 psi from the factory on stock GY

    Not sure why your TPMS would be set to that. I've had 28 and no warning in mine. 30 is the recommended pressure for cold PSI and stock size tires. Higher pressures will amplify the bumps in the roads.

    As for the suspension, it is more off road oriented. I notice the ride in our 4Runner SR5 is far smoother on the road, but my Tacoma TRD OR takes larger bumps better, particularly when going a bit faster. The tires do change the feel too. My Cooper Discoverer AT3 4S seem a little more wobbly on concrete than the stock Goodyear tires (for some reason), but not unreasonable at all. But the Cooper's also have a more aggressive tread pattern than the Goodyear tires did and far more tread.

    Try different tires the Goodyear tires are not the best I’m planning to change mine when it’s time for the new tires . I even find they grab imperfections in the road and will pull the truck to one side . The Goodyear tires are complete garbage .

    I’ve actually mentioned a couple times in this thread that I’ve had Falken Wildpeaks since about 600 miles, but both sets of tires didn’t change the vibes.

    Make sure your leaf springs are all torqued properly.

    There have been reports of loose mountings, especially around the axles.
