Summary
  • To keep the spare tire in good condition, check its tire pressure and tread regularly. You can also include it in your tire rotation, do a leak test on the valve stem, and keep the data code in mind.
  • Roadside tire replacements are easier with a well-maintained jack. Some ways to take care of it include checking for rust and damage as well as using it with a lug wrench.
  • Other road trip essentials drivers can keep in their ride include a portable air compressor, tire pressure gauge, tow strap, and basic tool kit.

Your car’s spare tire and emergency jack are crucial for roadside maintenance. Ironically, many drivers take these two for granted until they’re stuck in the middle of nowhere because of a flat tire.

How to Maintain Your Spare Tire

Like regular tires, spare tires also need to be checked and maintained. Here are some important things you should know about spare tire maintenance:

Check Your Spare Tire’s Pressure Once a Month

Make a habit of checking your tires’ pressure at least once a month and before any long trip. This includes your spare tire.

Make a habit of checking your tires’ pressure at least once a month and before any long trip.

Temperature changes can affect tire pressure. You’ll want your tires (including the spare) to always be in the right PSI (pounds per square inch) to keep them in great shape.

If you take your vehicle to a repair facility for maintenance like oil changes, ask the technicians to check and adjust your spare tire’s pressure while they’re doing the service. Most oil changes include tire pressure adjustments. However, the spare tire is not always checked.

How Much PSI Should a Spare Tire Have?

Spare tire pressure should be around 35 to 60 PSI. It varies depending on your actual spare tire.

Check the Tire Tread

Even if your spare tire isn’t used, it can still degrade over time, so make sure to inspect it for any signs of wear. You’ll want to ensure your spare tire is in good condition when it’s time to use it.

Include Your Spare Into Your Tire Rotation Schedule

Routinely rotating your tires ensures they have even tread wear, maximizing the tires’ lifespan and maintaining their optimal performance.

Experts recommend including your spare tire in your rotation schedule if you have a full size spare. It’s a common practice to move the spare tire to the rear-right position. Meanwhile, the tire that’s supposed to take that spot will be the new spare tire.

If you have donut spare, skip this tip. Donut spares are only meant to be used when you have a flat. They can last several miles, more than enough to get to an auto repair shop but certainly not enough for long-term driving.

If you’re unsure how and when to rotate your tires, you can consult your owner’s manual or ask a trusted mechanic for advice.

Conduct a Leak Test on the Spare Tire’s Valve Stem

You can also do a leak test when inspecting your spare tire. To do this, you simply have to drown the inlet with water to see if bubbles are forming.

If you notice bubbling, it means there’s a slow leak. You’ll need to have your spare tire checked or replaced as soon as possible.

Keep Your Spare Covered

If you have an outside-mounted spare, make sure to protect it from the elements and the heat of the sun. Road debris and UV radiation can break down rubber, decreasing your spare tire’s lifespan.

Keep Your Spare Tire’s Date Code In Mind

Make sure that you know how long spare tires last. Check your spare tire’s manufacturing date. Replace your spare tire if it’s already more than ten years old.

Test the Spare Tire Hoist

Many trucks and SUVs have spare tires under their vehicle. You can lower this spare tire to the ground using a spare tire hoist mechanism. To get the spare down, insert a rod through the buck bumper and crank down the hoist until the tire is on the ground.

Before going on a long trip, make sure the hoist mechanism is working. You don’t want to be stuck in the middle of the road dealing with a stuck spare tire.

Most of these systems are seals, so there’s no need to lubricate them. However, lack of use and the elements can degrade some of its parts.

Jack Maintenance Tips

Aside from your spare tire, make sure your jack is in good working condition as well. What will you do with a spare tire if you don’t have a jack? Without it, you won’t be able to lift your vehicle to replace your flat tire.

Here are some tips to keep your jack safe and well-maintained:

Check for Rust and Damage

Jacks can rust over time. Make sure to check for corrosion on the metal components of your jack, like the handle, screws, or lifting mechanism. Also, keep an eye out for other signs of damage. Inspect your jack to ensure there are no missing parts.

Don’t Leave Your Lug Wrench Behind

Your jack will be useless if you don’t have a lug wrench for your lug nuts, so always pack one in your ride.

Also, check if it’s compatible with the lug nuts your wheels currently have. This is especially true if you’ve recently replaced one or several lug nuts. In some cases, aftermarket lug nut replacements can be different in size compared to others. This rarely happens, but it wouldn’t hurt to check.

Other Tools to Bring During a Long Trip

Aside from bringing your jack, it’s also a good idea to buy a portable air compressor. If you’re in the middle of a deserted area, and you’re dealing with a minor tire puncture, it could help inflate your damaged tire until you reach a safer spot.

A tire pressure gauge, a tow strap, and a basic tool kit (with wrenches, pliers, screwdrivers, and sockets) will also be helpful.
