Get the Right Tires to Eliminate Trailer Blowouts!
Choose a tire and wheel combination that equals your trailer's GVWR.
This will give you a 20 percent minimum reserve load capacity.
Reserve Load Capacity
To understand "Reserve Load Capacity," you need look no further than the vehicle in your driveway.
Did you ever wonder why we have very few tire issues with our passenger cars, SUV's and light trucks, yet our trailer tires are a constant worry?
The vehicles we drive every day have a 20-30 percent reserve load capacity, yet our trailers are running 90 percent + loaded all the time.
So, if we want the type of safety and reliability out of our trailer tires that we have in our passenger vehicles, we first need to achieve a similar 20-30 percent reserve load capacity.
Example
2016 Mazda 6 has a GVWR of 4,288 lbs The tire is a P225/45R19 92W with a load capacity of 1,389 lbs per tire or a total of 5,556 lbs or 77 percent loaded at GVWR. A 23 percent reserve load capacity at GVWR. This vehicle has a curb weight of 3,130 lbs or 1,158 lbs of cargo capacity.
How do I determine how much additional capacity I need on my 5th wheel trailer?
Your GVWR should be on a tag on the trailer near the tire information tag.
Simply take your GVWR (Target weight) ÷ 4 tires = Target load per tire.
This assumes a 20% pin weight
Example (14,500 lb. GVWR): 14,500 lbs ÷ 4 tires = 3,625 lbs target per tire load capacity.
Remember, we want a 20% reserve load capacity so, we do not deduct the 20% pin weight.
Pin Weight Variation
Because pin weights will vary the preferred method is to weigh each wheel position on the trailer using a program like Escapees Smart Weigh program
In this example we have a 2012 Redwood 36RL that was Smart Weighed, with a 15,500 lb. GVWR.
The actual pin weight is 3,000 lbs and the heaviest loaded wheel position is the LF at 3,300 lbs
3,300 lbs x 120% = 3,960 lbs would be your target per tire load capacity.

"Unbelievable..."
Now that we’re back on the road, we’re able to experience the results of our upgrade. The only word I can think of to describe the difference is “unbelievable”. The stopping po Read Morewer in the new disc brakes is so much better that it takes the stress out of pulling the RV. When I apply the brakes now it’s almost as if I didn’t have the trailer behind me. I also feel much more confident with the upgraded suspension components.
I also can’t say enough about Barbara and John Alinger, our installers. They we’re so friendly and hard working. They had the upgrade done at the rally in about 4 hours then took a test ride with us when we were leaving to be sure everything was working well. They are great ambassadors for your company and products.

"Very impressed with the new disk brakes"
Wow! Josh and Heather finished little after noon today. Heather and I test drove my TV with the trailer in tow and I am definitely very impressed with the new disk brakes. I love them Read Moreand am anxious to get a full test in on the highway. I am sure I will love them. And I cannot say enough about Josh and Heather - they were total professionals and were attentive to every detail. I would have NO question about recommending their services to anyone!. Thanks for using them!

"Rare Quality Human"
In June, at the Northwood Mfg. rally in La Grande, Oregon we had your disc brake package installed on our Artic Fox fifth wheel. I'm the type of guy that likes to do things like this by Read Moremyself, but as I've gotten a lot older (and hopefully wiser) I decided to have someone else do the job. Ready to commit the extra funds for a safety improvement on our trailer, it was the perfect time. The perfectionist in me is a terrible thing to have because if I can't do it right then I usually don't do it at all. Brooke put me at ease as I watched his diligence to detail and how he made sure everything was aligned properly and worked to perfection. All the time with people coming by asking questions or making comments about problems they've had in the past. Brooke patiently answered all as he kept working, satisfying each rally member with explanations for the information they needed, but most of all, ME. I checked his work out to try and find problems or things he might have missed but it was perfect. You have a rare quality human working for you and should be very proud of the work he puts out and the ethics he has. Needless to say, I'm very happy with installation and performance of the brakes you supplied.
