'04 C5 LS1 ride
I recently bought an '04 Corvette. I drove it from Sacramento to our home in Tucson, Great Ride. Upon getting it home and driving on the streets of Tucson, " Lousy " would be kind. The car has 70K miles. I received no " History ", mechanical or other. The cars ride is quite Harsh, I can feel everything on the road. It is also getting more Rattles than I care for. With 70K on the odometer I am wondering what it might need to help these problems? Being that I have never owned a Corvette before, maybe these things are " Normal"? I am not looking for a " Cadillac " ride, I just want to hear the Radio. Yes, I am certifiably crazy!!

Vert or coupe? Is it a Z51? A Z51 IS going to ride rougher and you will feel the road a LOT more. Just the nature of the beast.
Yes, run-craps will affect the ride but tires really don't have a whole lot to do with things rattling. Unfortunately, to find the rattles it's just going to take some dedicated detective work.

Good advice above. Non-runflat tires can make a world of difference in the ride.

run flats
Does the car have RPO F55? Look at the sticker on the glove box door to see which RPO's came on the car.
There are still some F55 setups that still have the shock stuffers in place :

What tires are on the car? Run flats ? If so how old are they?? Manufacture week and year is branded on the side wall:
http://www.tirerack.com/tires/tirete...161029192742:s
Fun flats have very rigid side walls to begin with and the older the tire is the harder the rubber gets...
Has the car been lowered? Lowering the car reduces shock travel and makes the ride far less forgiving.
Lastly the street in Tucson are among the worst in the country. I speak from first hand experience..........

I was looking in the Glove Box and saw no RPO F55. The tires are Michelin Pilot Sport A/S Zero Pressure Plus ( I think I smell a Run Flat tire). 245/45 ZR17 95Y M&S front, and 275/40 ZR 18 99Y M&S rear.
The car has not been lowered. If the Date starts with DOT it reads, 4m FP 003x, if that is not it then I can't read the small print. Old Eyes.
The Tires look fairly new, but I have no papers on them. Everything looks original; shocks, exhaust, and suspension.

air pressure
The info you posted is NOT the tire manufacture date. It may be on the sidewall facing the inside of the car . I would look on all 4 tires and perhaps one of the 4 will have the date code on it facing OUT.
Zero Pressure is definitely a "Run Flat" tire. Have tou checked the pressures on the tires????? Perhaps they are inflated much harder that the 30lbs that is on the door placard.
Have you checked to see if the shocks have leaked out all their oil? Perhaps the shocks are gone and providing no useful function.
If you have a smart phone take a picture of the RPO sticker on the glove box door and post it............

The tires seem to be wearing more on the outside than the inside, too little air?

I was told scalloping was due to worn shocks.
You should change the spark plugs, don't wait till 100k as suggested. Michelin tend to give a softer ride. If you have a coupe there is a foam divider available goes behind the seats. Also a divider for vert. available.

just have to wait
4412 could be the 44th week of 2012. or approximately mid November. That would make the tires just about 4 years old.
If the front tires were wearing on BOTH the inside and outside edge then the issue would likely be too little air. If only the outside edge is wearing it could be an alignment issue. Might also be a balance issue if the outside edge is also scalloping. I just went through outside edge scalloping wear on the front of my truck. While the tires were balanced OK they were way out of spec for a "Road Force" Balance. I had Discount Tire do a Road Force Balance on all 4 tires and it is like driving a different truck from a vibration perspective. Time will tell if that totally corrects the outside edge scalloping wear. Alignment is well within specs.

I'll just keep the tires at 30lbs. until they wear longer, I'll wait until I can afford new tires and shocks.
The cars oil was changed when I bought it, and it still looks brand new. Being that is not driven that much, how often should I change the oil? I would think that I would have to go by time instead of mileage. Thanks again!
