So I see what the factory size is and I have 275/35/19 on the car I just purchased. 2005 Roadster with needs wings upgrades. There is so much information and it's almost overwhelming! So I'm sure this is on the forum but if anyone has suggestions.? The few wheel shops I've seen are always telling me something different. Just because they sell wheels and service doesn't mean they no anymore than ne.

 

This is what I have on the tires and their sizes.
