How to Choose the Right Tires for Your Trailer
December 16, 2025
Choosing the right tires for your trailer is not just about picking the biggest ones you can find. For tractor trailers and commercial-use trailers, the right tire can mean the difference between smooth hauling and a headache. Here is what to know before you buy.
Why Trailer Tires Matter
Trailer tires are built to handle heavy loads, resist heat buildup, and provide stability under pressure. Using the wrong type can lead to blowouts, uneven wear, and costly downtime—especially when you are hauling freight across Iowa.
Key Factors When Selecting Trailer Tires
- Load rating: Confirms how much weight the tire can safely carry. Match or exceed your heaviest realistic load.
- Ply rating: More plies generally mean a stronger casing. Heavy-duty trailers often need higher ply ratings.
- Tire type: ST (Special Trailer) tires are designed specifically for trailers. Do not substitute passenger or light truck tires—they are not built for the same loads and sidewall stress.
- Weather resistance: Iowa sees hot summers and icy winters. Look for compounds that resist cracking and stay flexible in the cold when your routes demand it.
- Tread design: Ribbed patterns are common on trailer tires because they can reduce rolling resistance and support straight tracking.
Common Mistakes to Avoid
Mixing tire types or sizes can cause uneven wear and poor handling. Running underinflated tires generates heat, which increases blowout risk—especially under heavy loads. Check inflation cold and follow the placard or manufacturer guidance.
