Tire Pressure will naturally decrease over time.
New tire will decrease 70 kPa (0.7 kgf/cm2) within a month.
A driver uses 3 test vehicles to perform tire rotation respectively at wear rates of 20%, 40%, and 60%. After analyzing the results, it is concluded that the optimal rotation approach is to have the load between 100-130% with a speed of 80km/h.
|Total Life * Cost/km|
*Includes the extended tire life and cost for 2 tire rotations
Load: 180-320% 40-50km/h (actual tire life before failure)

For the majority of drivers, retread tires save money!
How much money can you actually save?
Let’s do some calculations.
* Retread Cost Index = Retread Price Index - Tire Casing Sell Price Index = 60 – 10 = 50
* Under normal conditions, retreaded Giti tires can reach 80% of the mileage on new tires.
Retreaded Tire Mileage and Life Index = New Tire Mileage and Life Index x 80% = 80
