White letters - in or out on Rallye Rims ??

Sorry, should have mentioned the details:
This is the car they will be going on. Switching over to the Rallyes.
Just got the 15x8 Rallyes and will be using 275/60/15 on the rear and 215/70/14 on the front (thats what is on there now).
Looking at using the Firestone Firehawk Indy 500 for all 4 spots.

Except for the fronts you and I will be running the same size. Me - 68 FB fish. The rallys are getting powdercoated today and the 275/60 M&H drag radials go on tomorrow. In front 205/70-14 Kuhmos.

All black side out.

BTW, the Cooper 255/60's just did not hook up at the track and the 60ft times were going backwards no matter what I did burnout wise.
