This Rambler ST205/75R15 radial trailer tire is made for serious road time. With a load range D and an 8-ply rating, it carries up to 2,150 lbs at 65 psi while staying cool and steady at speeds up to 81 mph (speed rating M). It meets DOT specifications and exceeds FMVSS standards, so you can tow long distances knowing the tire is built for real highway work.
The Rambler radial’s construction pairs double steel belts with double polyester cords for durability and a longer tread life. A nylon tread-firming belt overlay helps prevent tread separation, giving you solid performance run after run. It’s built to handle heavy loads without giving up stability or confidence on the road.
The standard tread uses solid, continuous ribs with very few sipes for consistent contact and straight tracking. That design keeps wear even and makes it easy to spot tread depth with built-in bars for quick visual checks. You get a reliable, predictable ride that stays true mile after mile.
Radial ply construction places cords at a 90-degree angle to the direction of travel, reducing friction between layers. That means less heat buildup, lower rolling resistance, and smoother handling at higher speeds. It’s an efficient tire design that helps every trip feel a little easier on your tow vehicle and your nerves.
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"

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Taskmaster Rambler ST 205/75R15 Radial Trailer Tire in a load range D. Now this is a radial ply tire, so it's great for highway use. They do use the double steel belts and the double polyester cords, which combine for a nice long life. And they do use a nylon tread firming belt overlay around the tire to help prevent tread separation. Now this tire is designed to fit 15 inch diameter wheels.
The tire size, which would be stamped on the sidewall, ST for special trailer 205 75R 15. The R stands for a radial tire. Low range on this is a low range D, which means it's an eight ply rated tire. So it has a maximum load capacity of 2,150 pounds at 65 PSI. The other thing I wanna mention is most all the new trailer tires are coming through with speed ratings and they stamp that on the sidewall also and they indicate it by a letter speed rating.
So on this one where you find it is right after the size, you'll see two numbers for the load index and then the letter M, speed rating M will mean it has an 81 mile per hour speed rating. Now the tread design on this, they use a standard tread, has a solid cut continuous ribs with very few sipes or cuts that are put into the rubber. Sipes are usually what help with bad weather by breaking up any water that's underneath the tire. These tires, since they're designed for trailers, they don't really require the level of traction that would be needed on a vehicle that has braking or steering. This tire is an ST tire for special trailer, has sturdy sidewalls so they can handle the heavy loads and it is created specifically for trailers.
It's not intended for use on any other vehicles. This tire will meet the DOT Department of Transportation specifications and it does exceed the Federal Motor Vehicle Safety Standards. But that should do it for the review on the Taskmaster Rambler ST 205/75R15 Radial Trailer Tire in a load range D.

Excellent tire. I wound buy another one
Excellent. Fast, reliable and professi onal!
These tires are absolutely mint and there going to be holding 500 gallon of water I used to have a 6 ply lol so these should be just great can’t wait to get weight in the trailer and drive it around
Everything looks great. I think the tires may be a bit large for my application. I’m assuming these tires will fit on the rims I purchased but if not, how do I go about sending them back and getting a refund.
Was the perfect fit for my pop up trailer. Took them on a long drive and so far no problems. Smooth ride.
Nice tire.
I only had about 400 miles on these tires when I picked up a piece of road debris. I went ahead and ordered a new tire and had the other patched for future use as a spare. So far (other than the puncture) I love these tires much better than the OEM 6 ply set. I have a 34' Travel Trailer that weighs 6,900lb when dry.
I bought tires and they
came in the mail. Awesome job guy.
I selected this tire to replace old the 5.30-12 bias ply tires that were on my small utility trailer that I converted to haul Kayaks. I felt the radial option was preferable in terms of load and speed range of 81 mph compared to the bias ply limitation of 65 mph.
With these tires I feel more confident hitting the road for our next river trip. I’ll try to provide an update once I have some miles on these tires.
Nice upgraded tire. Excellent quality.
I needed an affordable yet quality spare tire for our car hauling trailer. I am impressed with the ratings and quality of this tire. The price was very competitive, too. My full order was eligible for free shipping, a big bonus.
we shall see once i place a load in my trailer
It will be better load rating for my little aluminum boat, I’ll have it installed tomorrow, will will be awesome. Thanks ya all.
Good tires, fast shipping
Very good communication from the start. Clear pricing, stock status, delivery time, and invoicing. Arrived in 2 days well packaged (in a box, not crushed by banding). Mounted them an hour later no issues. Hope these tires serve me as well as the service was from Etrailer
