How old can trailer tires be and still be safe?
Even if the tire tread has plenty of depth left and you can’t see any cracking with the naked eye, the generally accepted rule of thumb states that trailer tires should be replaced after about 6 or 7 years. Yours are about twice that age.
Can you use regular tires on a trailer?
Never use passenger tires on a trailer. They are usually rated Load Range B, a 4-ply equivalent, because their sidewalls are flexible for a smooth ride—far too flexible for trailer duty. They are not engineered to stabilize heavy loads or to handle the temperatures that build with them.

Can I put car wheels on my trailer?
Don’t. Trailer tires and passenger car tires have different structures to respond to different stresses. Using a trailer tire on your car, or a car tire on your trailer, could lead to disastrous consequences. Passenger vehicles interact with the road through their tires.
Can I use truck tires on my trailer?
Expert Reply: Light truck tires (LT) are sometimes used in RV applications but generally not on utility trailers. Light truck tires are a type of passenger vehicle tire and as such they are not built with as thick of a sidewall as trailer tires. A thicker sidewall allows a trailer tire to handle more vertical load.
How do I identify my trailer tires?
The first number in this size is the width of the tread, the second number is the size of the rim that it mounts on. Large size trailer tires are made up of three numbers. For example, a common trailer tire size is ST225/75R15.
Are LT tires OK for trailers?
Yes, both special trailer (ST) and light truck (LT) tires can be used on a 5th wheel trailer. They are actually the only two types of tires rated for this use. The reason for this is that tires on a trailer will be subjected to much harsher conditions that require a stiffer sidewall.
What does the R stand for on trailer tires?
asked by: Chris K. Expert Reply: The R in the ST20575R15 stands for radial which is the way the tire is constructed. The main difference between a radial ply and a bias ply tire is how the tire is constructed.
What does the D stand for on trailer tires?
The D is the designation for the internal construction of the tire. The D stands for diagonal or bias ply construction. That means the tire body plies inside the tire will crisscross. The 15 is the wheel diameter in inches and the C after the tire size will designate the load range.
