Welcome to Bike Forum.
Tire size is regularly debated. Search the sites: GCN, CyclingNews, RoadBikeReview, etc., etc., etc. Tons of articles.
Enough opinions on tires that you can justify just about any position you wish to adopt. Agree with above comment about checking frame&fork clearances before doing anything else.
we love pics of bikes. you get more replies, too.
