Is it safe to ride on these 45 year old tires?

Money is a little tight right now so I was wondering if these look too dry rotted to ride on?​https://i.redd.it/abhofcnv1s731.jpg​https://i.redd.it/syj8mhg02s731.jpg​https://i.redd.it/n7fgmv622s731.jpg​​​​​​​​I'm joking! Just bought new tires for the 1972 CB500 i'm redoing! :) Everyone have a good week, Happy Canada Day and 4th of July!!​​https://i.redd.it/mjfzwieo2s731.jpg via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/c81sef/is_it_safe_to_ride_on_these_45_year_old_tires/?utm_source=ifttt
