difference between 17x7 and 17x8?
hello everyone i have a pontiac g6 2008 sedan 3.5L and the rims i have atm on my car are 17x7. I just baught new wheels for my car for summer ( as atm its winter and im running on winter tires and rims ). The wheels i baught are 17x8. Canadian tire told me tires should fit and that the most important is the 17" diameter. Now im not too sure bout this lol i just want to make sure. What is the difference between 17x7 wheels and 17x8 wheels? is there a speedometer difference? or a handling difference?
