can anyone tell me whats the largest size tire they are running or can run with 14x6 magnum wheels. The old tires Im taking off are 235/60/14s which are big. Im surprised they were on the car because I was told a tire that wide isnt safe on a 6 inch rim. Whats the biggest tire I can use with no rubbing in the 70s series and the 60 series. Any info is appreciated.
