When You Fill Tires With Air, Check for Spare Parts
If you own a car or drive one, you probably (hopefully) check your tire pressures regularly. Under-inflated tires can be a huge problem, causing everything from crashes to accelerated tire wear and wasted gas. In other words, you want them to be properly inflated. And while you don’t have a pressure gauge, you should also check the pressure in the spare wheel.
On Reddit LifeProTips page original poster MANDOBURGER2 proposed to add a little air in the spare when you add air to the other tires, and wrote: “Some spare time with tires lose air, and you never know when you need to use it. … “While this is true of the fact that spare tires are losing air, and we do not notice this, we should clarify that the advice here is to check the pressures of the spare tires when checking other tires – adding air only if the tire needs it.
Also, as another poster in the thread points out , the recommended spare tire pressure is usually different from the recommended pressure for a regular size tire. Refer to your owner’s manual for the correct PSI (psi) value for both regular and spare tires. Typically, standard tires have a recommended PSI of 30 to 35 , while the recommended PSI for most spare parts is around 60 . But again, check what is required for your particular model to avoid over or under-inflating any of the tires. It may happen that you have a full-size spare wheel, in which case there will be no difference in PSI.
And to make some more backup, you should probably also check if you have a spare tire at all. Spare tires don’t always come standard on some new cars, so this is something you should look out for before you get stuck on the side of the road.
