loud road noise

[martynanasi]

Well I recently purchased a 2001 S boxster last fall. Got a great deal I might add. I have about 36 miles on it from the 29k it had at purchase and did get the 30k service done to it after I got it home from the dealership. Nothing bad except replacing some cabin filter, wipers etc. Still forked 800 Canadian for it though.

The tires seem very new and I did store the car for the winter (indoor and covered) and forgot to occassionally take it out and keep it charged. Eventually found out what happens though. Dead battery and it an ordeal to get charged again. Ok my bad

Anyway my main problem is the car has excessive road noise which sounds like I am in a lumber truck at highway speeds. Not sure if the tires got a flat spot from standing all winter or if there is a bigger issue. Sounds like a repeating thumping noise with some other sounds mixed in. The best I could describe it is it sounds like a porsche when driving at low speeds but once you get past 35 mph it begins sounding like I am in a rig. Hard to distinquish between whether it is loud road noise with thumping or just an engine getting overworked and rattling the car to death. I don't drive excessive though but know there is an issue and this is not how a porsche would sound even with super inflated tires...yes I did check tires if inflated properly. They were...
Since I am trying to baby this one and a new to owning a porsche not sure if it is actually coming from the road(wheels) or if there is something more serious I should be looking into. From what I read bearings could be the culprit but I am hoping it isn't something to do with the engine.

Gotta say I love this car though...well when it sound like it is suppose to.

Any help would be appreciated.
