Coverage
The policy covers all the OTR, TBR and PCR tire provided by Tanco and sold in the oversea market.
Period of Validity
Any tire with a complete serial number is covered against defects in workmanship and material for 3 years (radial OTR tire for 5 years) from the date of purchase. After that time, the warranty is terminated.
Notice: The tire age calculated from the date of purchase, If the proof of purchase is not available, the tire date of manufacture will be applied.
Coverage 100% adjustment
In case of any TBR tire with the defects in the workmanship and materials, if the remaining tread depth is worn out by less than 3.0mm (less than 1.6mm for the out of round and out of balance), Tanco will give 100% adjustment as per the benchmark price.
Coverage adjustment on a pro-rata remaining tread depth
In case of any TBR tire with defects in the workmanship and materials, if the remaining tread depth is worn out by more than 3.0mm and the remaining tread depth is worn out by not less than 1.6mm, Tanco will give the adjustment on a pro-rata basis multiplying the “Adjustment Benchmark Price.”
No warranty
Once the remaining tread depth is less than 1.6mm, the tire is considered worn out completely and no more adjustment.
Measure of remaining tread depth
Vernier caliper is used, when measuring, avoiding the wearing mark, the bottom of caliper spans in the measuring groove, and the vernier caliper must be vertical to the bottom of groove.
For longitude pattern tire: the position of measurement is groove depth of middle line on the tread. Measure the depth of four equal indexes on the tread circle, and the average value of the four data is regarded as the remaining tread depth and keep one decimal digits.
For lateral or block pattern tire: the position of measure is groove depth if middle line on the tread near to the wear mark, measure the depth of four equal indexes on the tread circle, and the average value of the four data is regarded as the remaining tread depth and keep one decimal digits.
Coverage 100% adjustment
In case of any PCR tire with the defects in the workmanship and materials, if they are worn out less than 15% of original depth, Tanco will give 100% adjustment as per the benchmark price.
Coverage adjustment on a pro-rata remaining tread depth
In case of any PCR tire with the defects in the workmanship and materials, if the tread is worn out more than 15% of original depth, and the remaining tread depth is more than 25% of original depth, Tanco will give the adjustment on a pro-rata basis multiplying the “adjustment benchmark price”.
No warranty
Once the remaining tread depth is less than 25% of original depth, the tire is considered worn out completely and no more adjustment.
