Due to their size, pneumatic tires are ideal for outdoor use as they can move easily over uneven terrain and the larger tires can move on gravel and sandy surfaces easier as their weight distribution won’t cause sinking. LINCO offers 8 inch pneumatic wheels, 10 inch pneumatic wheels, and 12 inch pneumatic wheels. Pneumatic wheels are not intended for high speed mobility with large cargos and are subjected to losing air which could lead to difficult mobility. If you do not have time or want to hassle with maintaining a proper air pressure in your pneumatic wheels, LINCO offers foam filled wheels at the same size and tread as the pneumatic filled wheels but do not require air to keep them filled. Although slightly more expensive, foam filled wheels never have to be refilled and last forever. Foam filled wheels also provide the same outdoor use as pneumatic filled tires do. Both pneumatic wheels and foam wheels are available in the most popular sizes and various treads through LINCO.
