How do I go about finding the correct wheel size?
2017 F-Type base/premium with 18" wheels.
Bolt pattern?
Offsets for front and back?

 

Go to wheels.com. They have the measurements for all the f-type factory wheels.

 

Another good resource is

https://www.wheel-size.com/

 

That's the one I was thinking of. Thanks

 

Thanks!

 

You still need to do your research. Verify the data from more than one source, if possible.

I recently fitted bigger wheels to my other, older, exotic car (so that I could find matching tires that fit F&R, in the proper speed and load ratings). I found some conflicting information.

Its the old adage: "Measure twice, cut once".
