When it comes to towing a trailer, one of the most crucial aspects to consider is the size of the tires. Trailer tires come in various sizes, and choosing the right one is essential for a safe and smooth towing experience. The wrong tire size can lead to reduced traction, increased risk of tire failure, and even damage to the trailer or tow vehicle.
What Size Are Trailer Tires?
The size of a trailer tire is typically indicated by a series of numbers and letters, known as the tire size designation. This designation includes the tire’s width, aspect ratio, and rim diameter. For example, a tire size designation of “ST205/75R15” would indicate a tire with a width of 205 mm, an aspect ratio of 75%, and a rim diameter of 15 inches.
Why is Choosing the Right Tire Size Important?
Choosing the right tire size is important for several reasons:
- Proper tire size ensures optimal traction and stability, reducing the risk of tire failure and improving overall towing performance.
- Incorrect tire size can lead to reduced tire life, increased wear and tear, and potential damage to the trailer or tow vehicle.
- Using the wrong tire size can also affect the trailer’s braking performance and overall safety.

Here are five FAQs related to “What Size Are Trailer Tires”:
Frequently Asked Questions: What Size Are Trailer Tires
Q: How do I determine the correct tire size for my trailer?
To determine the correct tire size for your trailer, you’ll need to check the manufacturer’s specifications or the trailer’s title or registration. You can also check the tire information placard, which is usually located on the trailer’s frame or inside the door. Make sure to note the tire size, load rating, and inflation pressure to ensure you get the right tires for your trailer.
Q: What is the difference between a trailer tire and a car tire?
Trailer tires are designed specifically for trailers and are built to withstand the unique demands of towing. They typically have a stronger sidewall and a more aggressive tread pattern to handle the weight and stress of hauling a trailer. Car tires, on the other hand, are designed for passenger vehicles and may not be suitable for towing a trailer.
Q: Can I use a spare tire as a trailer tire?
No, it’s not recommended to use a spare tire as a trailer tire. Spare tires are designed for temporary use and are not built to withstand the long-term demands of towing a trailer. Using a spare tire as a trailer tire can lead to reduced tire life, increased risk of blowouts, and decreased traction. Instead, purchase a dedicated trailer tire that meets the manufacturer’s specifications.
Q: How do I know if my trailer tire is underinflated?
To check if your trailer tire is underinflated, look for signs such as uneven tire wear, reduced traction, or a soft or squishy tire. You can also use a tire pressure gauge to check the pressure. Make sure to check the tire pressure regularly, as underinflation can lead to reduced tire life, increased risk of blowouts, and decreased towing capacity.
Q: Can I use a tire size that is slightly larger or smaller than the recommended size?
No, it’s not recommended to use a tire size that is significantly larger or smaller than the recommended size. Using a tire that is too large can lead to reduced traction, increased risk of blowouts, and decreased towing capacity. Using a tire that is too small can lead to reduced tire life, increased risk of overheating, and decreased towing capacity. Stick to the recommended tire size to ensure safe and reliable towing.
