New luxury crossover is really harsh over bumps?

[Anonymous]

Will I sound like a ditz making a service appointment over this? Our week old luxury crossover feels really harsh over random bumps in the road and small potholes. The ride setting is on normal or regular or whatever default is called. It does not have the gigantic sporty wheels, either. If nothing is wrong, I guess it is just our fault for not going on a longer test drive. I just didn't really notice it until a travel sports trip over the weekend.

BMW?

The way to evaluate this is by driving another example. Take one from the dealer for a test drive. If it rides similarly, that's the way that model was designed and engineered. Be sure the second sample is equipped like yours in terms of any optional sport package or optional tires, and that any adjustable suspection settings are configured the same.

If you have optional low-profile tires, they may be to blame. The shorter sidewall results in less bump absorption and in a stiffer, bumpier ride: https://www.discounttire.com/blog/low-profile-tires

Depends on the make. I went from mercedes to bmw and it felt rough. Before that i went from lexus to mercedes and it was soft and smooth

Could also be your tires. Some tires feel the road more than others.

Yes, especially if they are overinflated.

And i find run flat tires super rough

BMW crossovers are notorious for this. This is why BMW owners upgrade to the Porsche Macan and Cayenne, because Porsche has perfected sporty ride comfort.

Yep. I asked whether it was a BMW above. Rigid ride and run-flat tires can make things quite jarring in the ride.

DD specifically got regular tires on her BMW SUV because of our previous experience with run flats. There is no roughness in the ride of her SUV at all. It made a big difference.

The trouble with ditching the run flats is you need to get a spare, jack etc. and have somewhere to store them. My car doesn’t have a spot for that, just the trunk. Some people just keep tire goop spray in their car but that’s not a good solution either. I’ll probably get something from modern spare eventually.

My BMW has no spare, so I keep a plug kit and portable inflator under the cargo area floor. It's possible to buy spare tire kits, but they add back in the weight the engineers tried to eliminate and take up storage space. If necessary, roadside assistance can also be your friend.

While run-flats do usually have a harsher ride due to their stiff sidewalls, they also offer significant safety and convenience advantages if you have a puncture, especially in foul weather or in locations where it would be unsafe to stop. Instead of being stuck on the side of the road while trying to change the tire, or waiting for someone to come and do it for you, you can drive home, to a service location, or to somewhere safer to await further assistance.

That’s all true. I don’t want to wait forever for roadside assistance though. I don’t mind putting a donut in my trunk, but changing tires on the shoulder of 66 is no fun. I ended up ditching the run-flats and hope it won’t come back to haunt me.

Check your tire pressure! Frequently, cars that have been transported on carriers have had their tires deliberately overinflated to prevent excess bouncing. It's common for dealerships to fail to correct the tire pressure after delivery. This will give the car to feel very stiff when going over bumps. (I recently checked the tires on a car we bought a few months ago and the tires were 10 psi over the recommended pressure.)

Can you change the mode from sport to something else? I have a Mercedes and I can’t remember the modes, but there are three and one is softer.
