Smoother Ride Help

I not much of a mechanic, but it want a smoother ride in my truck. I bought it with a lift, 6" I think. No body lift, I think. 35 12.5 20's. Lift appears to be a Pro Comp. Tires and rims are also pro comp. Tires say 65psi on sidewall and that's what I've run them at. Seems like tires for a 3/4 ton. I'd like to get some 33's on 17" rims and maybe go a little narrower on tire width and add a 1" spacer. Would this help? Any ideas? Thanks

 

I dont believe a spacer will help you get a smoother ride, it may make it worse. Just depends.

How worn are the tires? New tires can be a huge difference in ride quality. Also seems like you may want to back the PSI off a bit on your current tires. Try going 55psi and see how it feels. If it feels too squirly then bump it back up.

Its hard to tell exactly what you may need with so many variables and not really knowing what you have installed.

If you really want a smoother ride you probably should drop it down to a 3 inch lift and get a set of 265/75/17 tires and rims to match.

 

Seems like you have too much air in the tires. I'd start there. The sidewall psi is 'max' not what you should be running in them all the time. Do the chalk test by putting a line across the entire tread in a few spots. Drive around the block and see if the chalk is removed evenly. If the center is removed but not on the sides, reduce air pressure and retry. You want the chalk to be removed evenly. Off the cuff, I'd guess air pressure on an empty Tacoma to be in the 30's for psi depending on tire load range.

 

They are wearing evenly and running flat on the ground, but I'll try reducing PSI

 

Wheel spacer, not suspension

 

Larger tires generally require less air pressure than a smaller tire, so 65 psi seems like way too much. I would start by running the pressures listed in your door jamb.

 

I've got the PSI at 40 now, and the ride is much better! Thanks everyone!
