Lightest weight track wheels

[Tracked Emira]

Is there a consensus on the best tire size for an 18/19 inch wheel setup for the track?

Depends on if you are running slicks or regular tires. If you call Greg from Greg’s race parts he can tell you because he knows both answers.
I will be using slicks so I have to find out myself. Did you pick what wheels you are tracking with yet?

One thing to consider is most manufacturers when stated from a weight that is for the smallest width on that size. When I was looking for wheels one stated from 18 pounds for the 19s but in our width it was 21.3. I would get them to show the wheel on a scale and commit to a weight in writing. For that kind of money they wanna be super light and strong.

Never thought to ask that question since the wheels will be a custom size. It will be interesting to see what the weight difference will be compared to other wheels in the same size and width.

To retain as much of the OEM geometry, I was thinking along the lines of 245/40R19 and 285/35R19 on custom ordered wheels with the same width and offsets as OEM wheels. For the 3.5 liter Emira V6, that would be 8.5x19 ET57 5x114.3 and 10.5x19 ET54 5x114.3 (the rears will be different for the 2 liter i4 Emira).
These tire sizes are available for the Yokohama AD09 and Bridgestone RE-71RS where I live, in addition to some local options like SHIBATIRE R23. Not as many options as the 18 inch, but doable...
