Question on tire pressure and shocks

So when i first got my JKU, i noticed that the tire pressure was approx 33-35. When i took it for the first oil change, i noticed that the tire pressure is now between 50-55. Now it seems that the ride is a little more rough than normal...does that lend it self to the higher tire pressure.

and then shocks...could it be just a cheap pair of shocks that might of came with the jeep and rocky ridge package...i was thinking of maybe upgrading to Fox shocks..heard good things about them. Not looking to spend a fortune, would like to stay under 500...but i'm also looking for a little smoother ride when i'm just on the regular pothole filled roads. Is changing out shocks a big job...what would you think someone would charge for doing that type of thing.

Rock Ridge Package includes the following:
3″ Rocky Ridge Suspension Lift
-Performance Coil Springs
-Pro Comp ES 9000 Shocks
-Replacement Front and Rear Sway-Bar End Links
-Foam Bump Stops
-Brake-Line Adaptor Bracket
-Adjustable Track Bar
18″ Method Race Wheels Ė Double Standard Powder Coated Wheels
35″ Mickey Thompson Tire Baja ATZ Tires
Rocky Ridge Full Armour Front Bumper
Rocky Ridge Full Armour Rear Bumper
Swing Out Tire Carrier
Rocky Ridge Custom Side Steps
8,000 lb Synthetic Rope Winch
LED Off Road Lights
LED Back-Up Lights
Jeep Grab Handles
All Weather Cargo Liners
Front and Rear Light Grilles
Speedometer Calibration Module
3 Year/36,000 Mile Warranty
Road Force Balancing
4 Wheel Alignment

Any thoughts...thanks.

Tire pressure that high will give you a rough ride. Bring the pressure down to where you had it if that worked for you. There's only a specific circumstance to run tire pressures that high, if you're carrying a lot of extra weight. It would be on a temporary basis. Whoever serviced your JK most likely added air up to the "max" sidewall pressure which would be incorrect for "normal" driving.

Check the sticker on the door jamb for the proper tire and pressure.
I run my JK HR at 33 - 37psi and it rides fine.

I run 34psi cold in my BFG All Terrain KO2's 275/70/17) and just replaced the shocks with the Fox Racing 2.0 Performance Series IFP shocks. The shop charged $85 to install all 4 shocks which took about an hour. I also added the Roost Shields to the rear shocks to protect the shock shafts from debris. It's a night and day difference, no more bouncing around. They need to be installed on a lift with yet suspension hanging because you cannot compress them by hand.
