We always say TBR tyre, PCR tyre and OTR tyre etc. for insiders of tyre industry, but the newbies don’t understand what’s mean of TBR, PCR and OTR etc. In fact, TBR tyre, PCR tyre, OTR tyres etc. are the short name of different tyre segment and Mike will explain what’s the difference of TBR, PCR and OTR.

What’s TBR tyre

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

What’s TBR tyres main sizes

TBR tyres 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.

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

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

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