15 x 6 or 15 x 6.5???

[Black Yaris]

personall I prefer the 15x7's
but if you are going to keep your stock tires on the new wheel go with 15x6, 15x6.5 has too much of a streched look for me.
Also if your car vibrates after you wheels have been changed it is most likely because they were not properly balanced, most newer wheels can only have weight on the inside. Most tire guys are too lazy to use the sticky weights are ment for that style wheel and just use hammer weights on the back lip... so when you get your new wheels on make sure you tell the guy at the counter you want a DINAMIC balance with sticky weights, and for not reason should they STATIC balance them... static balancing is the lazy way that makes car vibrate

Hope that helps
