What Is The Difference Between Full-Size Vs. Donut Tires? 

They are the same spare model but compact size suitable for temporary replacement like Donut. In contrast, full-size tires are larger-size and more durable.

The difference between these two types of spare parts is not only in size but also in some of the following characteristics:

  • More significant parts can be a long-term replacement because of better quality and longer service life. This one can also support the normal weight of many different types of cars.
  • However, this type of replacement accessory also has disadvantages such as high cost, heavy, and difficulty in storing.
  • To overcome the above disadvantages, a donut was born and can be easily found in the spare parts compartment because it is lightweight and much smaller than a standard model. Parts of this type do not have a very high quality of materials, thereby significantly reducing the cost.
  • The disadvantage is that it is not a high-quality tire, can not be available for a long time, and drives at a favorite speed. In particular, not all temporary replacement tires are suitable for your vehicle.

Are spare tires specific to the car?

Each type will have specific specifications for a particular vehicle model. Any difference in load, size, or nut position can make it unsafe to use on your vehicle. So make sure the spare one you choose is for your vehicle model and manufacturer.

How to check how old tires are?

To determine the age, you can rely on the identification number, also known as the tire’s serial number. In the United States, the National Highway Traffic Safety Administration (NHTSA) prescribes an identification number consisting of the letters DOT, 8 to 13 numbers, the letter, the size, the manufacturer’s code, and finally, the week and year of manufacture export.

What is the maximum time for a new spare tire?

It depends on the type of product and your usage and storage.
In theory, a full-size one has a lifespan of 6 to 10 years. To achieve the above maximum life, you need regular maintenance to ensure the product is always in the best condition.
Meanwhile, a donut can only go 50 – 70 miles. Beyond this distance, you need to change to a new backup option. Even if you don’t use this version very often, you should replace the tire after 8 years of storage.

What can I use if I don’t have a spare tire?

  • Step 1: Locate puncture, remove debris, if any.
  • Step 2: Fix the tire on the rim, then widen the hole. At this time, if possible, lubricate the hole.
  • Step 3: Insert the air compressor into the puncture. Then you pull the tool out, leaving only the plug.
  • Step 4: Adjust the plug to level with the wall. After that, cut the end of the plug to level with the wall.

Run with underinflated tires

You can still go a certain distance with underinflated tires, as long as the speed is below 50 mph. You also need to regularly check the pressure before deciding to drive for hours with a damaged tire.
