Close up of Lunar Rover Wheel

The Apollo Lunar Roving Vehicles were vital in our exploration of the lunar surface. Each LRV had specially designed wheels with titanium treads spread in a chevron pattern. This form helped keep the vehicles from sinking into the surface of the Moon. Each wheel was also equipped with its own electric drive and mechanical break. LRVs were very successful and astronauts were able to go as far as 7.6km (4.7 miles) from the Lunar Module during the longest LRV excursion.
