Durable Acrylic Enamel Finish

Maxion Wheels Vesper Acrylic Enamel Finish

This wheel has a durable acrylic enamel finish on the front. The finish is applied after the wheel goes through an environmentally safe zinc phosphate pre-treatment and is coated with an e-coat primer layer. Compared to powder coat finishes, this finish resists getting chipped from flying road debris or scraped from hitting a curb for a longer period of time. These acrylic enamel wheels performed for more than 1,000 hours in salt spray tests.

Improved Torque Retention Technology

Beveled Stud Holes Front and Back

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.

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"

Average Customer Rating:  4.9 out of 5 stars   (418 Customer Reviews)

This 15" x 6" steel trailer wheel has a 5 on 5 bolt pattern and a 3.31" pilot diameter. Improved torque retention keeps wheel secure when mounted on your axle. Acrylic enamel finish resists damage better than powder coat finishes.


This is a tremendous wheel! The 6" wide wheel is rated at 2835 lbs. Remember your rig is only as good as its weakest link, so a pair of these would be good for 5670 lbs. Overkill on a 3500lbs axle? Maybe, but definitely gives peace of mind, and the price is comparable. They even ship with the high pressure metal stems installed. The offset is neutral, so the difference from a 5" is only a half inch back spacing increase. Be sure to check your clearances from hub face to frame, but my Dexter 95" axle has plenty of clearance from the 80" frame. eTrailer has been the best vendor, period! I originally needed these wheels in April 2016 to replace the truck wheels I had, but the 5-on-5" wheels were not a carried item. Within days the team added them to their product line and had them shipped.
These newer Vesper wheels are even better than the originals from 2016. Thanks eTrailer team for another great experience!


I received the Trailer Rims ahead of the scheduled delivery date and I’m delighted with the construction and build of the Vesper Rims, best part is that they match the rare 5 on 5 Lug pattern to my Trailer Axle, thumbs way up


A GREAT product -- an exact replacement. The original valve has lasted for many years and am replacing all three Waste Valves. However, I have't install it, or the other one that arrive Saturday, but will this week. I did install the first valve which was operated via cable system two weeks ago. It works perfectly. I very much appreciated the friendly and knowledgeable assistance from all etrailer's employees. Very helpful and very knowledgeable. BTW, products well packaged -- no damage ...product arrive on schedule.


It was exactly what i ordered.

came a day earlier than expected.

Simple packaging , no fuss .



Once again etrailer has delivered at a good price with fast delivery.


Fast service merchandise well packaged and no damage !


Well built rim. It is made of heavy duty material. Glad I purchased from I have a trailer with a 3,500 pound weight capacity. This rim is just what I need for my spare. Nothing worse than having a flat and no spare.

Well it’s been a year already. Best way to not need a spare is to buy one. Haven’t needed it yet but enjoy the confidence gained from having it if I need it. Tire and wheel package looks good and holding air well.

Did not receive taskmaster. Receive another brand and have to go thru the process of returning and starting another order.

The product page is being changed now. I apologize for the confusion. This taskmaster is now under the Vespar by Maxion Wheels brand. The wheel has not changed, it has just been rebranded.
-- Etrailer Expert Sierra K - 06/14/2022


I bought these to replace the 5" white, spoked rims on my new car trailer. Can't beat the price and were at my door in two days. They are 1" wider and a much better wheel than the stock ones. I'd rather have aluminum but these look real good for a lot less than aluminum.

Still looking good and working fine.
Rick W - 02/03/2018


Thank they great alot better than the old Chevrolet truck rims that where on the trailer will be order one more in September


Wheels arrived in perfect condition, expertly packaged. Th e rims construction and paint quality exceeded my expectations


Have a new 7K car hauler/equipment trailer with ST205/75R15 Load Range C 6 ply tires on 15x5 silver modular rims rated at 1800 pounds. Wanted to do a tire and or wheel upgrade. Knew I could stay with a 205 tire and upgrade the Load Range rating, but fortunately I have plenty of extra width & height in the wheel wells. So I upgraded to ST225/75R15 Load Range E 10 ply tires, and etrailer had the exact rim for this upgrade. A 15x6 silver modular with a rating of roughly 2800 pounds well more than I will ever need. I was very happy with the online ordering process and shipping time. Packaging was superb and the rims looked great. During this process I learned about lug patterns on etrailer’s website great need to know information when ordering. With help from etrailer I know have solid piece of mind now in my rims & tires towing on the interstate in 100 degree heat. I will definitely look to etrailer again for any trailer needs.
Thank you!
Donald C


This wheel has a greater load capacity than others I looked at. Nice powder coat finish. These wheels will be used on a 16' trailer. The originals had load range C tires and after a blow out carrying a tractor I upgraded to load range E which required these wider wheels.


Good price, shipped and arrived quickly. Would buy again!


I ordered these wheels for my car trailer at around 9:00pm and they were at my house at 1:30pm the next day, the wheels were in perfect condition and fit as they should. I strongly recommend etrailer for all your needs.


My questions were answered and ordering was easy. Prices are reasonable and the product shipped quickly. Will use in the future when looking for trailer parts.


I found the correct rims using the information on this website. After purchasing them, they were shipped fast and are excellent quality. Now after one year of use, I’m still very satisfied with my purchase. They still look like new too!

Still looking like new no rust. No problems and I load my trailer heavy at times.

Great service. Great communication. Minus one star because one set of wheels were not packed well and we're banging together during this shipping.


Wheel is round and holds tire well. What else could I ask for?


These wheels are exactly what I wanted. They are a quality piece. The finish is excellent. had them shipped to my door very quickly. I am a satisfied and return customer. Keep up the good work!


The wheels are just as described. I believe they will make an excellent addition to my trailer.


Great looking wheel, excellent product and super fast shipping, best price around. I'm looking forward to future purchases. THANK YOU!


Excellent and quick service. The trailer rims fit correctly and look nice.


Great products fast shipping and products were as described. Highly recommend


Wheel was exactly as advertised and what I wanted.
Fast easy transaction.

Greatly appreciated.

As a follow up, no issues at all with Wheel. Great product.

  • Highest Capacity 15 Inch Diameter Wheel with 5 on 5 Inch Bolt Pattern
    Since you have upgraded from a ST205/75-15 tire to a ST225/75-15 tire you are also going to want to upgrade from a 15" diameter x 5" wide wheel to a 15" diameter x 6" wide. The highest rated wheel capacity we have with a 15" diameter and 5 on 5" bolt pattern is the Taskmaster Steel Mod Wheel # 560550SM1 which is rated at 2,830 lbs per wheel or 5,660 lbs per axle.

  • Back Spacing of Taskmaster 15 x 5-Inch Steel Modular Trailer Wheel 560550SM1
    The backspacing of Taskmaster 15 x 5-Inch Steel Modular Trailer Wheel # 560550SM1 is 3-1/2-inches. I went to our warehouse and took this measurement for you. Do note that the 3-1/2-inches is the wheel's backspacing. Once you mount a tire on the wheel there will be a change to the actual clearance between the tire and trailer frame. A 15 x 5 wheel like this can take either a 205/75-15 trailer tire or a 225/75-15 tire. The wider 225 size will have less actual clearance between the inside...

  • Help Finding Wheels and Tires for a Single Horse Trailer With 5 on 5" Bolt Pattern
    Currently the only wheels we carry with a 5 on 5" bolt pattern are 15" diameter. The Vesper Steel Modular Trailer Wheel # 560550SM1 has the largest diameter pilot at 3.31". While your current wheels both have a 3.5" diameter pilot you may be able to fit the smaller size since wheels this size are typically lug centric and not hub centric. If you have a gap between the pilot diameter of your wheel and the outer diameter of the hub you only need to ensure your pilot diameter is larger than...
