I have been reading about which width of tyre to fit to which width of wheel, and I am surprised to have come across a new guideline.
you can find it written here amongst other places -
www.carbibles.com/tyre_bible_pg4.html
For my example, you can choose a 195/50 15 tyre - it says you can fit to a wheel between 5.5" and 7" wide
If you then just reduce the aspect ratio to a 45 - so 195/45 15 - it says you then need a wheel between 6.5" and 8" wide.
Problem is, my wheel is 6" wide and the 195/45 gives me the rolling diameter I want.
How seriously should I take this guide?
I understand it is related to how much the sidewall can stretch on to the different rims, but not sure whether this is a rule that should be obeyed for safety or grip reasons, or it is just advice that can safely be ignored in this instace?
What will the result when fitting a 195/45 to a 6" rim??
