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.

"Wow, what a difference!"
Just finished having Disc Brakes installed yesterday by "Bill" the installer for Performance Brakes. Wow, what a difference! After completing yesterday we left on a 175 mile test journey. Read More Drove two lane twists, small towns, and freeway. The braking ability is much more than I expected. During my test ride with installer he had me do a hard brake situation going about 25 mph and we came to a stop in about half the distance of my old brakes. These brakes give you a lot of comfort when driving knowing I can stop quickly if needed. Interestingly, the old brakes which we took off only had about 8k miles on them and the pads were half worn and the eltromagnets were badly worn on two of the wheels. Granted we do more two lane twisty road driving than freeway driving. Bill the installer was very meticulous about his work and in addition found some wires that weren't crimp right (not related to brakes) and fixed them without saying anything until he was done. I would recommend him without any hesitation for Brakes and suspension work. I will report back if there's any change after our 175 mile trip home tomorrow.

"Disk Brakes Rock!"
Disk Brakes Rock! I just converted to disk brakes, using the Titan Performance Trailer Brakes. Whoa Nellie, do they stop smoother and quicker.
