The tire is the rubber casing and tread that meets the road.

What it's used for

Beyond grip, the tire protects the tube or holds the sealant in a tubeless setup. Park Tool says to replace a tire whose casing is damaged, and to check sidewalls and the bead for rips and holes (Park Tool tire guide).

What to look for

• The same size as your current tire. Park Tool notes tire bead diameter standards are not interchangeable (Park Tool). Your owner's manual lists the original size.
• Tube or tubeless. If you aren't sure which your bike uses, Park Tool suggests checking the bike's manual or asking the seller (Park Tool e-bike tools). Tubeless needs a tubeless-compatible tire and rim (Park Tool tubeless guide).
• A pressure range that fits your use. Recommendations are printed on the sidewall (Park Tool).

Using it safely

• Check the tread for nails, glass or thorns, and squeeze any cut to look for slivers (Park Tool).
• When mounting, check the molding line just above the rim. If it bulges upward, deflate right away and reseat the tire (Park Tool).
• If a bead is tight, use soapy water rather than grease or oil, and avoid sharp tools (Park Tool).
• For a hub motor wheel, follow your manual or the guide below for removing the wheel.
