What is the difference between TBR, PCR and OTR tire?

We often hear about TBR tires, PCR tires, and OTR tires, but what do they exactly mean ? Now engineers from MELION INDUSTRY company will explain you what is the difference between TBR, PCR and OTR tire:

TBR is the short for Truck and Bus Radial tires, so we can see that TBR tires are mainly used for Truck and Bus vehicles, sometimes we also call TBR tire as commercial tire because the TBR tires are used for commercial vehicles. Meanwhile, the structure of TBR tire is all steel wire, so the TBR tire has better loading performance.

TBR Tire sizes
TBR tires sizes mainly are 6.50R16LT, 7.00R16LT, 7.50R16LT, 8.25R16LT, 9.00R20, 10.00R20, 11.00R20, 12.00R20, 11R22.5, 12R22.5, 13R22.5, 315/80R22.5, 12.00R24, 325/95R24, 295/80R22.5, 11R24.5, 12R24.5, 425/65R22.5, 445/65R22.5 etc.

What’s PCR & PLT tire
PCR is short for Passenger Car Radial tires, so we can see that PCR tires are mainly used for car vehicles, sometimes we also call PCR tire as car tire directly becasue PCR tires mainly are used for car vehicles.

PLT tire is a wider concept, which includes PCR and Light Truck tire, but here Light Truck tire is little different with above TBR tire, because the PLT tire’s structure is semi-steel, which semi-steel structure PLT has more comfortable driving experience.

PCR and PLT tires main sizes

PCR tire segment has many sizes, such as 185/65R14, 195/70R15, 235/75R15, 215/60R16, 225/65R17, 225/45R18, 255/60R19, 275/55R20 etc.

PLT tire sizes include above PCR sizes and light truck tire sizes, such as 6.50R16LT, 7.00R16LT, 7.50R16LT, 8.25R16LT etc., but here this light truck tire structure is semi-steel.

What’s OTR tire
OTR tire is short for Off-the-Road tire, which OTR tire mainly used for the Giant truck vehicles in mine area.

What’s OTR tire sizes
OTR tire sizes minely include 16.00R24, 16.00R25, 17.5R25, 18.00R33, 20.5R25, 23.5R25, 26.5R25, 29.5R25, 21.00R33, 21.00R35, 27.00R49, 30.00R51, 33.00R51, 36.00R51, 40.00R57, 35/65R33 etc.

Now you have some understanding of TBR, PCR and OTR.

In addition, no matter what kind of tires, the tread wears out after driving tens of thousands of kilometers or the tire has reached the end of its lifespan after few years running. Do not throw away the retired tires because it will cause environmental pollution. Do you know that all tires can be retreaded and recycled?
