What tire size is F78 15?
205/75-15
What is the difference between 205 75R15 and 205 75D15?
The D in 205/75D15 represents that the tire has a bias ply construction whereas the R in 205/75R15 represents that the tire has a radial ply construction. The difference between a bias and radial ply is in regards to the directions of the cords.

What are bias ply tires?
The term “bias ply” refers to the internal construction of the tire. In a bias ply tire, the cords (plies) run at a 45-degree angle from bead to bead. The rigid construction means that bias ply tires do not conform to the road surface as efficiently as a radial tire.
How many years do bias ply tires last?
They also have advantages for carrying heavy loads. Radials, as most of us know, are vastly superior for tread wear. They’ll last an average of 40,000 miles vs. 12,000 for bias plies.
What is a major disadvantage of a bias ply tire?
Bias ply tyre: A bias tyre consists of multiple rubber plies that over lap each other. The center-tread area of the tyre and the sidewalls are interdependent and the plies that are overlapped form a layer that is thicker and not so much flexible resulting in the tyres being more sensitive to overheating.
Do all radial tires have steel belts?
Since the 1960s, all common tires have a carcass of cords of polyester, steel, or other textile materials, inlaid with several layers of rubber.
Which is better radial or bias tires?
Radial tires, however, do perform better than bias tires, and that performance is quickly noticeable. The ride is smoother, the trailer does not bounce and sway as much, and radial tires have a longer life. In the past, bias tires were known to carry heavier loads than radial tires.
Is Radial better than bias ply?
Radial tires dissipate heat better than bias-ply tires, which allows them to travel at higher speeds for greater distance. “Due to a rigid tread, single steel body ply construction and the absence of multiple nylon plies, radials are much more effective at reducing heat,” says Mills.
How good are radial tires?
Reliability. The tread of a radial tire does a better job of gripping the road and provides improved durability and maneuverability. Comfort. Because their plies run radially from bead to bead around the tire instead of diagonally, radial tires are more flexible – giving you a more comfortable ride.
What happens when you mix radial and bias ply tires?
What this means is that at highway speeds, the bias-ply tire will heat up and actually lose traction. While it is not recommended that you not mix radials and bias-ply tires on the same vehicle, some do in race applications.
Can you mix radial and bias tires?
Never mix radial and bias-ply tires on the same axle. When you select a pair of replacement tires in the same size and construction as those on the car, we recommend you put them on the rear axle. A single new tire should be paired on the rear axle with the tire having the most tread depth of the other three.
Can you run bias ply and radial on a motorcycle?
Above all, do not mix bias ply and radial tires on the same motorcycle unless it is with the approval of the motorcycle or tire manufacturer.” The radial front and rear are almost universally used on these types of bikes, including for road racing.”
Can you mix radial and bias ply tires on a trailer?
No matter which type of trailer tire you choose – radial or bias-ply – make sure you don’t mix them on your trailer. Since their internal construction is so different, each type performs differently, and combining them can negatively affect your trailer’s ride quality and the tires’ life.
Can I mix R and D tires?
Expert Reply: It’s fine to use a radial-type tire as a spare (a tire with “r” in its size code) with a trailer that has Bias ply “d” tires but for a short distance in the event of a flat tire. But mixing tires is not recommended for everyday use because their internal construction is different.

What is a radial tire vs bias ply?
A radial tire allows the sidewall and the tread to function as two independent features of the tire. A bias tire consists of multiple rubber plies over lapping each other. The crown and sidewalls are interdependent. The overlapped plies form a thick layer that is less flexible and more sensitive to overheating.
Are bicycle tires radial?
Bicycle tires have the threads of the fabric running diagonally, (“bias”) from bead to bead. Modern car tires have the main threads running straight over from one bead to the other, known as “radial” construction.
