I read about Proton S70 review mentioned that the entry level uses a 205/55R16 tyre.

I had a old camry which I had just changed very recently for 4 * 205/65R15 tyre.

Using this tyre model I had done some checking, Toyo CR1, I found that the

205/55R16 - Price RM272 per pc
205/65R15 - Price 245 per pc.

Both shopee online competitive price from the same shop.

However it seems to me that 205/55R16 is a slightly smaller tyre as per the following :-




The question I had in my mind is 205/55R16 tyre costlier to manufacture than a comparable 205/65R15 tyre ???
Isnt 205/65R15 more costly to manufacture cost wise since it had a slightly bigger lump or rubber & perhaps metal??? Same width, more sidewall and a slightly higher tyre overall than 205/55R16

Or the cost is mostly similar (or very small difference) but the marketing decided that 205/55R16 will price higher than 205/65R15 since as per your statement above, R16 must have better margin than R15 regardless???
