Purchased a 330ci conv. w'sports pkg. The tires almost look flat and it drags bottom on speed bumps and my driveway. The BMW dealership said this was normal for 3 series. I don't want to damage the bottom of the vehicle and feel over time it will. Thanks for any suggestions or do I just live with hitting bottom????

There's not a lot of ground clearance. The tires shouldn't look flat, but they are low profile.

That doesn't sound right. There isn't a LOT of ground clearance, but my car is over 2 years old now and I've never scraped the underside on anything, although I have been very careful in driveways. It definitely shouldn't scrape on speed bumps.

Not all speedbumps are created equal. Some are very high and steep. My 1994 E36 has bottomed on those.

Either the tire pressure is proper, or it isn't. If tire pressure is proper and the suspension is at spec, the problem is the speedbump and not the car.

I was told at the service dept my tires were correct pressure and they were supposed to look like that b'c they were low profile. I bought the vehicle w'12,000 miles on it but was sold as a new vehicle b'c it was a reps vehicle (it isn't brand new). My first question was why are the tires so low and why do I hit bottom driving into my driveway. I was told by service, I should back out of my driveway at an angle so I don't hit bottom??????! That was the answer service dept gave me. I'm bringing it in b'c I want e'thing checked under there. Thanks.

If you haven't driven anything similar to this.. you'll just have to learn to slow down, going in and out of driveways, etc... The angle thing is correct, as well... The car just sits very low... Most likely, you are scraping the front spoiler..

Once you adjust, it will be all gravy...

and you believed what the service dept told you? go get a tire gauge and measure them yourself! takes you like 2 minutes, tops. you can even get the nifty digital ones.

how steep is your driveway? if you have a really steep driveway, or a driveway with a very high curb, it's possible that you could scrape the bottom of your car if you aren't careful.

Yeah, any quick changes in elevation can do it. For example, even a little dip for a gutter in front of a driveway could be enough.

Also the scrape is just plastic, not metal. Isn't there also a second air dam below and behind the front air dam?
