Default Re: Help me with tire sizing pls.
The second number in a tire size is aspect ratio - the size of the sidewall expressed as a percentage of width (first number.)

60% for 205mm is going be quite a bit larger than 50% for 195.

1 'section' of sidewall on a 205/60 will be 123mm high, as opposed to 98mm on a 195/50.

Grab a ruler.
