FAQ

1.  Can I put Boar Wheels as a direct replacement for my 16” trailer tire/wheels?
Yes. If your trailer has 8 on 6.5” lug pattern and is lug-centric (conical seat lug nuts) with ½” or 9/16” lug nuts, then the Boar Rancher single wheel or the Cruiser 67 Aluminum wheel will be a direct bolt-on replacement. With single wheel, 5/8" studs, the Rancher 673T or the Cruiser 67 & Muret 75 will be the best hub centric (centers on the center bore) replacement option for you. If your trailer has 16" dual wheels with an 8 on 6.5" lug pattern, hub centric, and you're currently running 235/85R16s, then the Hooper Dual wheel will be a perfect direct bolt-on replacement. You can always call us with your trailer specifications (axle size, GVWR, current tires size & stud size) and we can help you determine the correct application.

2. I have a trailer with 6 lug hubs and rims. What are my options?
On trailers with 6 lug hub design, in many cases, you can switch out your 6 lug hubs on the same axle spindle to 8 lug hubs. You can visit www.tktrailerparts.com or call them at 833-300-0433 for assistance with this.
 
We are also working to release a direct bolt-on 6 on 5.5", 19.5" wheel in late 2018 or the first half of 2019.

3. I have 225/75R15s on my trailer. Do you have anything that will work for my trailer?

Yes. In May 2018 we have a Super Cargo 225/75R15 LRG (14PR) all steel tire coming out with a 3,500/LBS weight capacity and 75/MPH speed rating.

4.  What is the maximum air pressure I can run in the 225/70R19.5?
In a Load Range J, the maximum psi is 125.

In a Load Range G, the maximum psi is 110.

In a Load Range F, the maximum psi is 95.

5.  What is the maximum load I can run on the 225/70R19.5?
3,640 lbs. is the maximum load at 95 psi for a Load Range F.

3,970 lbs. is the maximum load at 110 psi for a Load Range G.

6,005 lbs. is the maximum load at 125 psi for a Load Range J.

6.  Do you offer dually wheels?
Yes.  The Hooper Dual is a 19.5”x6.75” dual application rim.

7.  Do you offer an aluminum alloy wheel?
Yes, we offer the Cruiser Aluminum line. The Cruiser 67 is available in either a lug centric design for 1/2" & 9/16" studs or a hub centric design for 5/8" lug studs and a 6,050/lbs. weight rating. The Muret 75 is available in the hub centric design for 5/8" studs only and a 6,400/lbs. weight rating.

8. Will I be able to find replacement tires easily?
Yes. The 225/70R19.5 is in the top 5 commercial tires sold in North America. They are on many pick up and delivery vehicles (FedEx, UPS, USPS, etc.) and are on many medium-duty trucks (F450, F550, 4400 & 5500 models). Because of this replacement tires are readily available through most tire dealers and online. You can also find high tread used tires in most areas.

9.  Why not just go 17.5” on my trailer?
Below are the three main reasons why 17.5" tire/wheel combos may not be right on your trailer:

  •     Limited availability:  
Since 17.5" tires are not widely used as Original Equipment outside the trailer world, it can be more difficult to find a replacement.
  •     Lower test standard: 17.5" tires and smaller are tested to a different standard than larger commercial tires. According to the to the NHTSA the test standard for inch pounds of breaking strength for a 17.5" tire or smaller is 6,300/in.lbs. with a 3/4" plunger. For 19.5 and larger commercial tires that goes up to 15,000/in.lbs. with a 1.25" plunger. The construction standard is not equivalent to the larger rim diameter commercial tires.
  •     Application
:  17.5s are a trailer specific design. They are not designed to be used on trucks, and most newer trucks could not accommodate a 17.5" if you wanted to run the same size on your truck and trailer. Only 19.5s will fit most modern trucks that come stock with 18" or larger rims.
