When I took delivery of my xB I noticed that the ride was extra bumpy so I checked the tire air pressure. It was 45+ and I had read somewhere that tires are overinflated at the factory before shipping. Dealers are supposed to check the tire pressure before delivery to the customer, but mine didn't. You may want to check the tire pressure if the ride seems uncomfortable.

 

i check my tire pressure weekly.....just to be sure.....

 

Same thing happened to me. Before when people said the ride is great even on stock 15", I was thinking are these people nut? You are too nice when you use the word "uncomfortable". It was like riding on basketball when on the freeway. It felt like the car is going to lose control on every bump. The ride is so much better with 30 psi. Luckily no one have an accident because of that.

 

so 30 psi is perfect?

 

i have been experimenting and 34psi works best for me on 241/40/17 tires/wheels

softens the ride a little and handles well too!

btw, what is a headlight strobe? i see it in the specs for your xB... isn't that what Smokey uses
