I've got no experience with minis directly, but this comes from experience with my VX220
They're designed to run 17" on the rears and on the front it's 16"
As standard they come with 17" all round, when changing the difference i found was:
16" give a better turn in, but they also have more sidewall flex than a 17"
17" will give more understeer but to some people they look better. |
