Do I need a pair, or will one mat work for my vehicle?

One mat can work depending on your setup—many owners use a single mat under the drive wheels for lighter situations. If you're running a heavier rig or want redundancy, order two pieces. Check your wheel base to decide.

Can these be used on pavement, or are they sand and mud only?

These are built for soft terrain—mud, sand, and snow. Using them on hard pavement can wear the grip surface faster and isn't ideal for traction gains since pavement doesn't need the help.

Do these need any prep or treatment before first use?

No prep needed. Rinse them off after use to remove mud and sand, let them dry, and stack them for storage. They'll hold up fine with basic cleaning between trips.
