Monaco 0 pit stops?

I have a race in 3 hours and I'm wondering if it is possible to do the whole race with hard tires. (75% of length) sorry for my English.

What is the wear percentage for your hard tires in practice? Multiply that by the number of race laps. Is that less than 100? Less than 80? It may be possible but you may not like the results...

You should try it. You will learn some valuable things!
