What Is a Social Security Number (SSN)? A SSN is a nine-digit identifying number is in the format xxx-xx-xxxx. Any individual who is a U.S. Citizen, a permanent resident, or a temporary alien resident who is authorized to work in the United States, must have a SSN.
The most common cause of a flat tire is puncturing of the tire by a sharp object, such as a nail, letting air escape. Depending on the size of the puncture, the tire may deflate slowly or rapidly.
I got a simple tire puncture with run flat tires and the dealer would not fix it. Buy a brand new tire. If the tire has more than 10,000 miles on it, buy two new tires. BMW does not recommend running tires on the same axle with too much of a difference in tread wear. Not a fan of these tires.
