can't do the math.

13" average 130
14" average 160
16" average 230
17" average 300

does the material cost alot for each inch increase?
u see 13 vs 17 just 4 inch diff. but cost more than double

oh understand. by far I believe even there have taxes to protect local manufacturer. but the price still few times. which is give the doubt of manufacturing cost diff by few times ?

yes, i know what you mean.
the surface area is bigger but usually raw material usually cost 30% of their manufacturing cost.

I every 4k tukar tyre only rm 90

4k km. 1 pcs 45 ringgit.



yes you guessed, is kapcai bulat.
