Tire Size for 19
 

I just got a new set of Boze 19X10 for a 67 Camaro that has not been tubbed and was wanting to know if I should run a 275 or 285 and what profile would work best for these wheels.

275/35/19's on a 10" look perfect.

C6 wheel is a 19x10
 

and it runs a 285/35/19...tall tire 27.xx Total width bulge to bulge is 11.5

I run a 275/35 on my 19" rear rim on my '69. I have 9.25" width rims that were custom made from a 10 inch hoops because I was a bit nervous of fitment with a 10" rim and at the time 19" rims only came in 10" or 8" widths. I can't see how I could get a 285 width tire in there without tire rubbing problems, but my model year is different than yours and I know your wheel arch is higher on your quarter panel than mine. The 35 series tire is definitely the right series.
