All-Terrain Tires

These tires have wide, undulating grooves that flow like a river, the pits of which are tinged blue and always wet. A vehicle that has its tires replaced with these magic tires is considered under the effect of the spider climb and water walk spells.

The vehicle must have all of its tires replaced with these magic tires for the vehicle to receive its effect. For example, you would need two all-terrain tires for a motorcycle, or four for a truck. The tires expand or shrink to fit any vehicle that would normally have tires.
