Will these tires significantly help my biking? I bike to school which is 4.5miles away, and there is a bike lane 90% of the way (other 10% has to be on the sidewalk). It's Uphill on the way to school.

Thanks in advance!!
Update: *********Also what tools would I need to replace the tires correctly? If possible, a video too, I keep finding replacements for the tube only. Would be greatly appreciated.**********
