Tire size chart: the sizes cars in Thailand actually use
137 tire sizes you will find on cars in Thailand, from 14- to 21-inch rims. Every row is worked out from the numbers on the sidewall with the same formula as the tire size calculator and matched against 74 models whose Thai-market specification lists that size. Open a size for the full breakdown, the sizes that can replace it and how far the speedometer moves.

How to read this chart
Overall height is the diameter of the whole tire before it carries any weight. It decides whether a new size throws the speedometer off and how much the car rises or drops. Sidewall is the height of rubber between the rim and the tread on one side: the taller it is, the more cushioning and rim protection you get. Circumference is how far the car travels in one turn of the tire. Sizes with similar heights can often stand in for each other, and every size page states exactly how many percent apart they are.
How the height in inches is worked out
Take 265/65R17. The sidewall is 265 x 0.65 = 172.25 mm, the 17-inch rim is 17 x 25.4 = 431.8 mm, and adding a sidewall top and bottom gives 431.8 + 344.5 = 776.3 mm overall, or about 30.6 inches. Every row in the chart is worked out the same way. Pickup shops in Thailand often name tires by this height, as in a 31-inch or 33-inch tire, which refers to the whole tire rather than the rim.
Can't find your size?
The chart covers sizes fitted to cars sold in Thailand and the sizes that can replace them. If yours isn't listed, the tire size calculator takes any size, the comparison chart lines several up side by side, and plus/minus sizing finds the closest size when you change rim diameter.
