Uncomfortable ride after 6000 miles.

Bet it's the tires. A large tire is going to affect your suspension more than the stock ones. I put 33's that are load range E and it definitely took away some of the ride quality on rough roads but it's not unbearable.

 

I have the same issue and concerns with my truck. Although I have a 2" front spacer lift and 1" rear cornfed lift the ride over bumps is very harsh and the springy feeling is instant and rough. I'm looking at the Icon shocks as well. I have 285/75 Duratracs which are garbage tires when it comes to ride quality. I'm thinking of chanigng to the 295/70 Terra Grappler G2 tires to soften it up some. I wish they made a load range C tire in 35x12.50r18 for those who just like the look. Lol.

 

The ride was great the first 5000 miles with the leveling kit and tires. Now it’s not worth a dang.

 

It is the spacer lift and those big E load tires. Both hurt the ride. Then add the fact that you probably have the stock black shocks, which are marginal at best with stock tires. Those shocks will have problems controlling 35inch E load tires which will impact the ride in a negative way. I would suggest looking around for the OR package shocks for sale, should be able to find low mile takeoffs for cheap from when folks starting lifting the 2022s more.

Check your air pressure, it will ride like a brick if too high. 35s on 18 inch wheels generally need around 35psi. I think you are too high at 40psi. But use this tool to get you in the ballpark on pressure

 

Thanks. I lowered the pressure to 35PSI and really did not notice a difference. I am going to order a set of ICON 2.0 and new foam bump stop kit for the back and hopefully that helps. I think ICON is my best bet for the rear right now. Not that many options out there.

 

Any obvious leaking from rear shock seals?

 

None that I can see.

 

I know this isn’t your thread, so I don’t want to go too far off topic— AND, spacers will make your ride harsh no matter what shocks you run. I suggest you be cautious about installing premium coilovers in combination with spacers… the ride will remain harsh as long as you run the spacers and, spacers added to the coilovers to increase height for clearance… often will cause the shocks to collapse in fun good off-road conditions.

You may know this already; I add it for the OP and anyone that reads this thread later.

 

If I ran 35 psi in load e tires they would melt , that surprises me some of you guys can get even tire wear with 35” load e running 35 psi

 

ikr, I'm running 45 cold on 33's

 

Rotate your tires and see if it moves the bounce. I had basically a 34-1/2" STT Pros on my 19 and after some wear, the ride was not as good. Feel your tires, see if your can feel if the tread is higher from one lug to the next. If you have them, try the factory wheels n tires.

 

Big tires and level kit ruined my ride.

 

I run 33s too, 275/70, and they require more air pressure than 35x1250s. That tire pressure calculator is a great tool when moving from stock tires to a different size or load rating. Gets you in the ballpark with pressure. Then adjust up or down a pound or two based on how your load and drive the truck.

I sure wish moving to a larger tire on a Tundra didn't usually mean E load. C load would be perfect on our trucks but few options unless you drop down to 17 inch wheels. The calculator said 275/70-18 needed 39 front, 41 rear, to match the load capacity of the stock SL tires at stock pressure. I generally run them 2-3 lbs under for a better ride. I air up when towing or hauling or carrying more people and just keep an eye on the tire wear to make sure it is staying even. And of course rotate and balance tires every 5k miles.

 

I dropped my psi to 32 this weekend and it felt a little smoother. I'm on 285/75r18 duratracs.

I still don't understand how a spacer makes the ride stiffer? I think majority of people are running the spacers that sit on top of the strut so there is no added spring compression like the Westcott kit. I didn't notice any change in ride with my spacer, just the tires.

 

I'm with you on the spacer. I think it just lifts the truck as if there was a jack on the diff. You lose droop travel. I still think it's the tires heavy off road/all terrain tires need to be rotated more often. Especially if the alignment is not just right.
