As for tire sizing, as best i can tell your bike would have come with 25mm original spec. The SRAM RED is speced to work with 28mm (again as best I can tell)

IME with 105 5800 speced for 28 mm, i do need to deflate the tire or push hard to get by the brake pads, but one settled in I close the the quick release and have good range to adjust the calipers.

I would suggest 25mm or even better 28mm will help with with punctures.

then you need to decide on the tire and need to balance performance vs puncture resistance.... you have a race bike.....how are you riding it and what to you want for ride.

if you want performance with reasonable puncture resistance I have had good luck with the Conti GP 5000 in 28 and the continental race light tube. No flats in 400 miles. I used them for commuting pre covid. I also used Vittoria Corsa G ....they were great riding but horrible for flats averaing a flat every 80 miles (i am 250 lb and run the tires at about 90f 100 rear)
