Costco Tire Pressure

So, I pulled over and Googled Costco’s phone number. I asked for the tire center and asked the nice gentleman who answered if they did tire pressure and how much it was. What is this? He said yes they do and it was free!

Does Costco fill air for tires?

These Lifetime services include inflation pressure checks, tire balancing, tire rotations, as well as flat repairs. Upon the service of your tires we also install new rubber valve stems (Note: TPMS valve stems and accessories will be an additional charge).

Do I need to be a Costco member to buy tires?

Tire Installation Requirements

Costco will not perform services on tires purchased by non-members. Costco will only install tires authorized for a specific vehicle. If you are unsure if your purchase is an authorized fitment, contact your local Costco tire center for assistance.

Can I mix nitrogen and air in my tires?

It’s never a good idea to drive on an under-inflated tire. Using compressed air in tires that have previously been filled with nitrogen will not harm your tires. While mixing the two won’t result in an adverse chemical reaction, it will dilute the purity of the nitrogen and lessen its effectiveness.

How do you pump up tires at Costco?

Look for the complimentary inflation stations (usually located near the Tire Center) and park under one of the signs for “Tire Inflation Parking Only.” Follow the instructions listed on the station, and then you’re ready to get back on the road. Easy peasy!

Does Costco use nitrogen in tires?

The warehouse club uses nitrogen to fill its tires instead of compressed air, which is what most other dealers use. “Nitrogen retains tire pressure better over time than compressed air, which can positively impact the life of your tires, as well as the fuel economy of your vehicle,” according to Costco’s website.

Why is nitrogen better for tires?

Since nitrogen molecules are bigger than normal air molecules, it is harder for them to leak out. This means a tire filled with nitrogen will maintain air pressure longer. Therefore, they say, you’ll roll on tires that are always properly inflated, resulting in better fuel economy and longer tire life.

Why do they put helium in car tires?

“The body of the tire provides traction and is the container for the air. It’s a very high tech balloon.” Balloons filled with helium are lighter than air, so won’t filling tires with helium save weight?

Do nitrogen filled tires lose pressure in the cold?

Myth: Nitrogen is not affected by temperature changes, and therefore maintains proper tire pressure regardless of climate. Fact: Tires filled with nitrogen maintain inflation pressure longer than compressed air-filled tires in fluctuating temperatures.

Can I put oxygen in my nitrogen tires?

Yes, you can add air to a tire that has nitrogen in it. In fact, air is comprised of 78% nitrogen, 21% oxygen, and 1% other gases—topping off a nitrogen-filled tire with air will simply dilute the pure nitrogen with a small amount of oxygen.

What does SPRE mean when filling tires?

PSI: An abbreviation for pounds per square inch (psi). The amount of air inside a tire pressing outward on each square inch of tire is usually expressed in psi.

Does filling tires with nitrogen instead of compressed air reduce pressure loss?

Nitrogen-filled tires lost an average of 2.2 psi. The results show that nitrogen does reduce pressure loss, but the reduction was only a 1.3 psi difference from air-filled tires over an entire year.
