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.

"Dennis Knows His Stuff!"
Dennis knows his stuff! We connected through Performance Trailer Braking when I inquired about upgrading the brakes and suspension on our Momentum Toy Hauler. Dennis and his assistant, A Read Moresher, arrived right on time and got right to work. We had them swap out the factory suspension for the Road Master Comfort Ride slipper spring set up with shocks, Kodiak disc brakes, and Dexter 8k axles.
Super nice guys, very professional and efficient. They did all the above in about 8 hours. Dennis travels the west helping customers upgrade their suspension and braking systems. He also attends RV rallies to do prearranged upgrades.
I highly recommend Dennis of SonChaser RV for any suspension & brake upgrades you may be considering.

"Thank you all"
Just wanted to give a shout out to the installation team that works through your company, Josh and Heather Shrader. They installed my brake kit today on my 5th wheel trailer. They were Read Moreboth very professional, they both took time to explain what they were doing and invited me to ask any questions that I might have. Their work was done in a timely manner and when they were done their work area was left clean and all old parts were placed in one spot with all cardboard for easy disposal. It was a real pleasure to have met them both. And by the way, the new disc brakes are awesome! Thank you all.

"“WHY DIDN’T I DO THIS YEARS AGO?!?!?!?!!!”"
Just a quick note to share some final feedback. I completed the installation with no incidents and I only had to place one phone call to address an actuator wiring question. That quest Read Moreion was handled effortlessly, professionally, and left me with a crystal clear understanding of how to proceed. I took the camper out for a 60 mile test drive 2 days ago and it went flawlessly. The only negative I came away with was the burning question “WHY DIDN’T I DO THIS YEARS AGO?!?!?!?!!!”. This setup is a game changer and if I knew then what I know now I would have done the conversion on a brand new camper before even taking it out on its maiden voyage.
You folks put together a very nice and concise kit package and the directions are quite straightforward. The technical call is a wonderful safety net, just in case. I couldn’t be happier with my purchase decision and I will recommend you folks to anyone with even a mild interest. I look forward to years of highly effective braking from my rig, thanks to your superb kit.
