Question:

I am looking for a trailer tire, ST175/70/R13. Do you have one? Is there a replacement for this size with another number. It goes on a Ranger Boat trailer.

Usually, a 175/70-13 is a passenger car tire. What you can do to verify is look at the tire again and if there is a number after the size, like 82Q, it is not a trailer tire. Trailer tires do not have this additional number, which is a load index and speed rating.

The closest fit would be a 175/80-13. This tire will be the same width as your current tires but will be 1-3/8 inches taller. For just the tire without the wheel, you can use # AM10210, which is a load range D radial tire.

If you need a tire and wheel combo we have them with 2 different bolt patterns; 4 on 4 and 5 on 4-1/2. I have included a link to our tire FAQs for you.
