Corrosion-Resistant Finish

The steel wheel goes through a 3-step finishing process that makes it both attractive and corrosion resistant. The wheel is first submerged in a zinc phosphate bath to ensure good paint adhesion. It is then e-coated with an acrylic primer base and the outboard side is finished with baked-on DuPont powder paint. The light e-coat on the inboard side of the wheel reduces friction between the wheel and your hub and eliminates the flaking that can occur with a heavily applied paint finish.

Improved Torque Retention Technology

The automotive-rated center disc is raised and the stud holes are beveled and uncoated for better clamp force retention. This technology helps the wheel stay tight against your hub without the need for constant retightening.

Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.

Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Taskmaster Tires and Wheels - Tire with Wheel - TTWAS15B5WS Review

Today we're going to review part number TTWAS15B5WS. This is the Taskmaster ST205/75/D14 Bias Trailer Tire in a load range C, mounted on a 15 inch white spoke wheel with the 5-on-5 inch bolt pattern. This tire and wheel assembly is ideal for boat trailers, stock trailers, utility trailers and campers. This is is a steel wheel with the 8 spoke design. It's very sturdy and corrosion-resistant. The wheel itself uses a 3 step finishing process.

Basically, it includes a phosphate zinc bath, then an e-coat primer, and then a white powder coat that's put on the outboard side of the wheel. On the inboard side of the wheel, it's lightly e-coated, helps reduce friction and provide rust resistance with less flaking. This wheel does use the ITR technology which is improved torque retention. Basically, that means to help keep the wheel securely in place on your trailer, they use uncoated stud holes and they're beveled and this to help to offer better clamp force retention. This is a biased-ply tire.

It's constructed with strong nylon cords. It is great for off-road and agricultural use and it also has the tread depth bars, or tread wear indicators, like you'll find on your passenger and truck tires and what that is is if you go along the shoulder of the tire, you'll see a TWI with a triangle. That triangle points up to the tread, and they're about every 12 inches around the shoulder you'll see one and where that triangle points is to the tread. If you look in the tread grooves right at that triangle, there's a raised section, almost like a rubber speed bump that goes in each tread groove and that is at 2/32 tread depth. What happens is that as this tire wears down and your tread wear indicator will go straight across, that's indicating the truck tire is worn out because it's at 2/32 tread depth.

So it gives you a nice visual indicator of the tread wear on the tire. This assembly does meet the Department of Transportation specifications and it does exceed your Federal Motor Vehicle Safety standards. A few specs, we'll start with the wheel. Dimension is 15 inches which is measured inside to inside, or bead seat to bead seat. It is 5 inches wide.

The bolt pattern is 5 lugs, 5 inch bolt pattern. It does use a wheel lug size of 1/2 inch by 20 and the weight capacity on the wheel is 1,870 pounds. The pilot hole diameter, which is this large hole here in the center of the wheel, goes over the hub on your trailer, it's diameter is 3.19 inches. Now, on to the tire. The tire size is right on the sidewall: ST for special trailer, 205/75/D15. The "d" means it designates diagonal belt construction which means it's a bias tire. Now, the section width on this tire, 8 inches wide. Overall diameter from the very bottom to the top inflated is 27-1/4 inches and the capacity is the load range on the tire is C. It means it's a 6-ply rated tire so it has a maximum load capacity of 1,820 pounds at 50 psi. That should do it for the review, part number TTWAS15B5WS. This is the Task Master ST205/75/D15 Bias Trailer Tire in a load range C mounted on a 15 white spoke wheel with the 5-on-5 inch bolt pattern. .

Great company to work with. I have in the past and like other transactions, this was perfect. Fast delivery, packed great in boxes protecting the tire and wheels. Free shipping on top of the already lowest prices I was able to find. Like the other products I have purchased from etrailer.com, I have no doubt this purchase will provide years of quality service. Thanks Tommy C. for all your help.


I never had a spare tire before and bought a spare from etrailer just in time as I had a flat and thankful I had it mounted on a mount I also got from etrailer.


The wheel and tire I ordered arrived in a timely manner with NO damage at all. The product is exactly what I ordered at the lowest price I could find. I am extremely happy with this purchase from eTrailer.com!


I have had these tires and wheels for 1 year now. I ordered these but was sent silver rims instead of the white. I didn't care, so threw them on the trailer. One thing to note is these aren't balanced, so they do make the trailer vibrate at the correct speed. It's easy enough to have them balanced and take that away though. I'm happy with these and the higher speed rating.


First time using entailed but will use again. Easy to use and the tires arrived on time and were exactly what I needed. The detailed instructions on how to determine the 5 bolt pattern i haave was really SUPER helpful and was the selling point for me to use etrailer.


I purchased this tire and wheel combination for my 11 year old car trailer that had cracked weathered tires and needed to be replaced badly. I had the exact same tires and the old ones lasted for 11 years, so I was happy to find this same brand again. I had very good service and was shipped to my door in 3 days. wow! All 4 wheels and tires were shipped in individual protective shipping boxes, and were in prefect condition. It don't get any better than that!

Still working great, I have no regrets buying these tires, I only hope that my trailer will last as long as the new tires will!

George, The tires I purchased worked out great. I was in need of wheels and tires. Locally, I was going to have to order them and was going to cost more than what you offered. Thanks and I will be using you in the future and have already recommended you to several friends.


I bought two of these tires to replace the ones on a cargo trailer. I have since used the trailer to move household goods from Florida to Maryland and Florida to Atlanta. The tires performed well with no issues, and they still look good. I used the information on the website to determine the bolt pattern of the wheel (not as common a pattern as others), and obviously the information was right on. I will definitely use this source again.

Great Tire and rim combo. etrailer.com is a great place to buy quality parts. Their outstanding service and expertise are unmatched by others in the industry. No reason to look anywhere else for what you need. Very happy with the products I received and the follow up service they provided.


I checked all the local places for the wheel and tire size needed and no one carried it. You guys did and I'm extremely glad you did. I spend a good part of an afternoon on the computer trying to find a company that carried what I needed and I finally came across your web site. With the information you had on how to measure the bolt pattern, I was able to order and get exactly what I needed. Your company is great and the product i purchased is excellent.


The wheel and tire combo arrived at my door in two days, each boxed individually. They appear to be a direct replacement for the set on trailer so I can replace 3 and use my unused spare. Not much more for wheel & tire combo so I now have the three i replaced to use as spares. etrailer is excellent place for tires in my opinion :-)


These tires and rims have served me well. My trailer came with Taskmaster tires/rims that have worn out and I just replaced them with new tire/rims. My trailer is a 16" tandem axle open trailer with a 7000 GVWR.

These tires and rim are still working great.

I was in a jam for a spare tire for my trailer couldn’t find any anywhere. These guys came in clutch and it arrived just in time.


I bought my single axle trailer with no spare. eTrailer hooked me up with a perfect tire and wheel match to the original ones. The tire/wheel arrived in just two days, and the shipping box even had two hand holes to make it easy to carry. Great job eTrailer!


The new trailer tire and rim was just what I needed..


ordered on Monday showed up on Wednesday. great dealing with you guys i will be back soon. the only thing i suggest is to check your tire pressure. they called for 50psi and one tire had 60 psi and the other had 42psi no big deal i set them at 50psi before i lowered the trailer. thanks again


I had been trying to find this tire and rim combo locally and was unable to locate one. I was looking for a spare to match a recently purchased trailer , the dealer wanted $35.00 more to order one. It came in 4 days in perfect condition I would definately use etrailer again


Awesome product. Shipping was a breeze! Had a hard time finding this particular trailer tire at all the shops around my area. They had it in stock and on my doorstep 3 days later. Great job!


These trailer rim and tires cost less than the same tires only locally. The showed up on time and even were inflated to proper air pressures. installed all 4 and loaded the trailer with about 2300 pounds and drove from Washington state to Moab and back, 2158 miles with no problems.


Nice wheel & tire. I had been looking for this bolt pattern for quite some time. This is exactly what I needed.


The communication from etrailer.com was superb. The tires and wheels were exactly as described and a perfect match for my Big Tex CH60. Free shipping was extremely quick. Quite simply. No one could even come close to what etrailer.com offered. I will be shopping here again.


I was looking for a matching wheel and correct sized tire that came on my Big Tex trailer. This was an exact match on the wheel and it came with the correct sized tire. The price was great. I am very happy with this transaction.


Great service as always. Let me tell you a little story, 2 years ago I needed to replace the bearings and race in my trailer. Wanting to get it on the road quickly, I drove 30 minutes to the local auto parts store (NAPA). They gave me the wrong parts, on day 2 I returned the wrong parts, they gave me the correct bearings, but the incorrect seals. On day 3 I returned to Napa, they was having a problem figuring out the correct seal, I had them go to your web site, which had all of the info they needed. Never again will I get trailer parts anywhere but etrailer.


After a year and about 800 miles of light loads, tires are holding up very well. Good tread, and wheel paint is still in good shape after storing outdoors. No cracking. A little pricey at first but am happy I spent the money up front. We will see how things hold up in another few years. If all goes well I will buy more.


Perfect fit on a forty year old trailer. The website measuring instructions were extremely helpful in determining the correct rim and tire. The local tire stores wouldn't even touch my old rim and tire. So glad I found you guys. I will be ordering again!
