When you’re covering long distances, heat buildup can be the enemy. The Rambler ST205/75R14 Radial Trailer Tire is rated for 81 mph (speed rating M) and built with double steel belts, double polyester cords, and a nylon tread-firming overlay that reduce rolling resistance and help prevent tread separation. That means cooler running and longer tread life when you’re at highway speeds.
This tire is designed to handle the weight of heavy hauls without flinching. With a 6-ply rating and a maximum load of 1,760 lbs at 50 psi, it’s built to stay stable and dependable mile after mile. The sturdy sidewalls are made specifically for trailer use, giving you solid load support where it matters most.
Durability isn’t just about materials—it’s about meeting real standards. This radial trailer tire meets Department of Transportation (DOT) specifications and exceeds Federal Motor Vehicle Safety Standards (FMVSS). That’s proven reliability you can trust every time you roll out.
The standard tread pattern uses solid ribs with very few sipes, designed for consistent tracking when towing straight ahead. It wears evenly and gives a clear visual indicator of tread wear through built-in tread bars. It’s a straightforward design that stays true to its purpose—steady and predictable performance on the road.

1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Hi, everybody, Andy here with etrailer.com. Let's take a look together at this Rambler ST 205/75R14 Load Range C Radial Trailer Tire. Now, this special trailer tire or ST tire, has sturdy sidewalls to handle heavy loads. This tire is created specifically for trailers, and it's not intended for use on other vehicles. This radial tire is constructed with double steel belts and double polyester cords for increased durability and a long life. The nylon tread firming belt overlays are gonna help prevent tread separation, and the tread bars are going to give you a quick visual indicator of tread wear.
Now, as I stated at the beginning of our time together, and as we have stamped here on our tire, this is an ST 205/75R14. This is going to fit 14-inch diameter wheels. This is a Load Range C, meaning it has a six-ply rating, and the maximum load is 1,760 pounds at 50 PSI, and this has a Speed Rating of M, indicating the maximum speed of 81 miles per hour. This tire does meet the Department of Transportation specifications, and it exceeds the Federal Motor Vehicle Safety Standard specifications. But I think that's gonna wrap up our real quick look today.
I do hope that our brief time together was helpful for you. Again, my name is Andy, thank you for joining me.

Glad to hear they’ve been working well and holding air without affecting the ride! No worries about the photos—we appreciate you sharing the one you could. Have you noticed any change in how the camper handles when driving?
