A car that has alloys with tires on them size 195 (195/50R15 to be exact).
Would it be safe to put 185 tires on the wheels? (186/60R15 to be exact).
I would have thought not. As 195 refers to the width of them, and so the width of the allow wheels are 195 in my logic, but perhaps not.
What do you think? Google seems to say that's it's fine. Hmmmm.
