Not every tire takes the same amount of pressure. It often depends on the tire size and how heavy the vehicle is. You can find requirements on a sticker that is usually yellow in color and placed in the door jam of the car door on the side of the driver. Sometimes pressure requirements are printed right on the tire on the side wall. Other places manufacturers hide the sticker is under the door for the fueling area and in the glove compartment. PSI is the increment in which air pressure is measured. It means pounds per square inch. Most car tires take about 30 to 40 pounds each tire.
When we got everything settled Bruce and his son went to buy two more tires. We needed one for a spare and one to replace the flat one on the camper again. He found a couple of used ones that may work for a while.
I told them I was going to call everyone I could to get a better deal. Of course they did not pay attention to me. So, we got all packed up and on our way again. Now Bruce had to drive slowly again because we did not have a spare tire.
We made it into Morarity, NM. The stations were all closed and it was hard to find any one that had a tire for sale. We stayed again in a truck stop parking lot, and I cooked supper in the camper. The next morning Bruce went out hunting for a spare tire. He found a tire shop that had two of them and we bought them. The spare we had put on was chipping off tread and so he changed that one again and put another tire on the spare rim. So, we are off again.
You may do well to get a tire iron set. These will help you in more kinds of mechanical tasks other than just changing a tire. In a set, you will usually get one longer iron with two shorter ones. These kinds of sets can be used for a variety of things during tire changing.
It is so easy to forget about tire maintenance. Routine checking of tire pressures and wear patterns are so important for tire longevity and safety. Dual tires, can be a pain or almost impossible to get an accurate tire pressure reading. Be sure the valve stems have the proper metal extensions or the one piece long metal valve stems that fit some of the truck rims. Only put extensions on metal valve stems not rubber. The rubber valve will not hold up under the added stress created by extensions. You may have to buy a tire pressure gauge that is designed for checking dual tires. If you are unable to check them yourself, for whatever reason, any quality tire store will be very happy to accommodate you.
A good car repair shop will provide replacement tires, fix suspensions, axles and everything else that is causing the increased wear and tear at an affordable price.
Another part that should be inspected is the bead and side walls. Beads are the portion of tires that fits the rim of the wheel. Side walls, on the other hand, are literally the side of the tires. The bead, whether new or used, must be undamaged or otherwise, they will not fit the rim properly. When it comes to side walls, refrain from buying used tires with deep cuts on this portion. If you are not familiar with these parts, you can ask your mechanic to come with you on the date of purchase.
You can even go to auto shops or tire stores and sell them there. Just know you wont get their full value, maybe less than 45% of what you paid, they still have to make a profit on these a junk yard. Maybe you can even exchange them for money off on new tires, or even trade them in for a better set of used wheels.
Checking tire pressure is very simple. Go to your favorite auto parts store and buy a good quality pressure gauge. Keep it in your glove box. The primary cause of tire damage is improper inflation. Your tires lose pressure over time, which causes unnecessary stress, early and irregular tread wear and poor gas mileage. Tires will not perform at their best without the right air pressure. You can either read the sidewalls for recommended pressure, or call your dealer for the correct pressure. Properly inflated tires will give you a more comfortable ride, and will ensure optimal gas mileage.
