Rough/stiff ride after new struts/shocks

There is breakin period.

Also, since you got new tires, the place probably set your tire pressure to 40 psi.

Higher tire pressure = more bounce, coupled with new shocks.


iPhone ?

 

I’m running 44psi and all 4s since they were new. The wearing is on schedule to meet the 80,000 mi spec., even les schwab tires says the same when I physically let them do the rotation, said tire wear is on schedule. But I don’t drive like a maniac to be the first one at the next stop light, I drive like my avatar

 

I wish. Tire places are not to over inflate tires pass the driver door jab manufacture specs.

 

non oem shocks and new tires, tough to compare to worn oems.

how many miles on her?

 

you may be right, i didn't realize that

 

okay, i am not sure. call a toyota parts dept and ask

 

Mind the tire specs. While the door jamb may say 35 psi, the tires may suggest something else. I bought 4 recommended tires from Discount Tire, for my Gen 2 Prius. The PSI rating on them is '30 to 52'. The car is sluggish at door jamb, but normal at 40. I'm not sure why these are a 'recommended product' for my Prius, but the wear is even all around, and mileage is typical at the higher psi.

 

the door jamb is the factory rec.

the tires have minimum and maximum parameters.

but these two can conflict as ford and its tire supplier found out with the explorer

 

I had the same experience and think it's the jump from 89H to 91H tires.

I used Goodyear Assurance Fuel Max and Bridgestone Ecopia EP20 which both had max sidewall pressure of 44 psi, and that's what I ran them at. I never had any issues with ride or wear.

I replaced rear shocks, front struts, and tires simultaneously. The new tires have a max sidewall of 51 PSI but running them at 51 PSI is out of the question. It's like riding in a covered wagon. You feel everything.

This is what I did and is my advice to you. I ran them at 35/33 (the door) for a tank and checked the MPG against the last tank. It was not as low as I thought it would be, and the ride was as pretty mushy as you would expect. I went to 40/38 for a tank and got very close to the MPG I previously got. The ride stiffened noticeably.

At some point I got to 44/42, got the same MPG as pre-change, and no noticeable change to the ride.

 

About 1 week.

There's a pressure embossed on every tire sidewall, indicated as max pressure at max load, something like that. As far as I know the tire manufacturers recommend you follow what the car maker says. What is that 35/33 (front/rear)? The main "jimmying" I'd do with that is to just set all four to 35

 

I have a 2013 Prius V 3, and recently put KYB struts and shocks on my vehicle. The ride is now terrible. Worse than before the change. I am feeling everything on the road. The supplier is refunding me the cost. I brought the parts to my mechanic to install. Has anyone have a good experience with a different manufacture's products? I want a good ride.

 

Plus one pound, that'd get lost in the noise, lol.
