How Do You Find The Speed Rating Of A ST205/75R15 Trailer Tire

Question:

Good Morning, Can you tell me what the recommended Highway speed for a ST205/75R15 tire on a 2020 Intec Sol Horizon camper with a GVWR of 3900? Thank you

The speed rating of your ST205/75R15 tire will be stamped in the sidewall, and not all tires have the same rating.

For example we offer the Karrier ST205/75R15 Radial Trailer Tire - Load Range C # AM10244 which has an 81 MPH speed rating where a different tire like the # LHWL300 has a 75 MPH speed rating.

If there is not a speed rating stamped on the sidewall of your tire you will want to stick to 65 MPH max.

I included videos of the products mentioned for you to take a look at.

@Vince Hey Vince. I have no way of looking up what your tires speed rating is unfortunately. You're going to need to check both sides of the sidewall, and you're looking for a letter like M. If you can send clear pictures of both sidewall sides I can check em out, you can take them to a local tire shop to have them check too, or if you cannot find a speed rating you'll want to stick with a 65MPH max like stated above.
