Have a 2018 GS model. Had the dealer install winters on the standard 17" wheels. Want the get 19" wheels for lower profile tires to improve handling.

My questions are -

1. What is the standard wheel width and off set for the factory 19" wheels??
2. Has anyone installed aftermarket wheels and do you have pictures and/or specs on what fits?

 

225/45/19 seems to be the most common 19" tyre on GL Mazda 6.

 

225/55/19

 

Just go to the Discount Tire or the Tire Rack websites and put your vehicle information in then you'll be able to click on and see the tire size options for your vehicle.
