I have a 2015 Grand touring. I leave car outside at night and I bring it to sketchy places somtimes. I want to change wheel size from 18 to 16 is that possible?
Tire Rack.com lists 16' tires as an option for this car.

 

Welcome the forum

Well then you answered you own question from Tire Rack.

The speedo will be off slightly so keep that in mind.

 

sure you can. go to discount tire or any other shop that sells rims. you could probably find some used. saying go to the tire shop so you are sure they fit.

 

The Tire Rack not only has complete comprehensive application guide from the wheel manufactures but also the engineering size dimensions so a DIY can actually use the information to determine if a wheel not listed to fit may fit based on that research.

If not project vehicles would basically be SOL to easily find a custom wheel for say a ride that a rear end was shortened.

 

i see a set of 2016 Wheels on ebay, its the same generation. it should fit, yes?

 

please ,never mind my last message- i sound a bettr deal...thanks again
