Default 305/25-20 and 245/30-20 on a 997 TT?

Anybody running 991 TT sizes on their 997 TT? Also, I was looking at stock
997 TT sizes and noticed quite the difference between front and rear diameter,
wasn't this an issue on the 996TT? Anybody know the tolerance?

Meant to say, 245/35ZR20 in the front and 305/30ZR20 rear.

26.75" Front diameter
27.2" Rear diameter
Or a 1.75% error so should be ok.
