I purchased a set to OZ Leggera HLT in 19x8.5 ET53 and 19x12 ET51 with 245 and 305 PSS. Installed them and now I see that the rear tire is really stretched out on the 12" rim. I plan to order a custom set in the near future (i.e. HRE, CCW, etc) in the factory width 8.5/11.5 but with offsets that are a bit more flush. I will then use the OZ wheel for the track.

In order to remedy the 305 stretched tire on the rear 12" wheel, I have two options and I would really love to hear from track guys which way to go on the rear wheel.

Option 1) Exchange the rear 19x12 for a 19x11 ET50 and use the 305 tire. My worry here is that the 991.2 now has 11.5 rear and I'm not sure I should downsize the width.

Option 2) Keep the 19x12 wheel and exchange the 305 tire for the same PSS in a 345/30. Same O/D.

Either solution is temporary till my custom set is delivered. Question is which rear width is better for the track and provides me more options with tires.

Thanks for reading.
