The stock tyre of ALTIS is:
185/70 R14, circumference is 1931mm.
Assuming we have it changed to:
195/70/R14, the cirucmference is now 1975mm giving an error of 2%.
Not to also mention that such a size would be rare, maybe not
manufactured too.
Another scenario is we use a wider profile and reduce the aspect
ratio (this scenario gives the smallest error):
195/65/R14, the circumference is now 1914mm giving an error of -1%.
Once again such a tyre size maybe rare thus cost more.
Thus, the best way is to upsize the Rim size to keep the error to a
minimum.
