Just had Les Schwab put new tires on my ‘08 Cabrio. I thought the car looked a little different and it turns out they put the same size tires on the front as on the rear! They’re 175/55R-15 all the way around. The fronts are supposed to be 155's. So, my question is, does anyone know why the tire sizes are different from the factory? The larger tires clear the wheel wells just fine and I don’t notice any difference in handling. Should I just keep them the way they are? Thanks for any input you have.
