1. An apparatus for increasing the buoyancy of a wheeled vehicle, comprising: a ski to be disposed under at least one tire or wheel of the wheeled vehicle;a pair of L-shaped boots, wherein each of the L-shaped boots comprises a bottom wall secured to the ski and a side wall substantially perpendicular to the bottom wall, wherein the side walls of the L-shaped boots are configured to laterally constrain the tire or wheel of the wheeled vehicle;at least one mounting bracket positioned between the ski and the bottom walls of the L-shaped boots, wherein the mounting bracket comprises holes configured to independently align with the ski and the boot; andat least one tire block pin for connecting the pair of L-shaped boots to one another to increase rigidity of the apparatus and to rotationally constrain the tire or wheel of the wheeled vehicle. 2. The apparatus of claim 1, wherein the apparatus is modular. 3. The apparatus of claim 1, wherein the ski comprises a contiguous surface that prevents the tire or wheel of the wheeled vehicle from touching the ground beneath the ski. 4. The apparatus of claim 1, wherein a tire or wheel having the apparatus mounted thereon does not rotate to drive the wheeled vehicle. 5. The apparatus of claim 1, wherein a tire or wheel having the apparatus mounted thereon is prevented from rotating by a device applying brake pressure. 6. The apparatus of claim 1, wherein the tire and the side wall of the L-shaped boot are in direct contact. 7. The apparatus of claim 1, wherein a distance between the side walls of the L-shaped boots is adjustable. 8. The apparatus of claim 1, wherein a length of the tire block pin is adjustable to accommodate a distance between the side walls of the L-shaped boots. 9. The apparatus of claim 1, wherein the side wall of the L-shaped boot is hinged to the bottom wall of the L-shaped boot. 10. The apparatus of claim 1 further comprising one or more straps for securing a wheel of the wheeled vehicle to the ski. 11. The apparatus of claim 10, wherein the one or more straps are secured to one or more tie downs positioned fore and/or aft of the L-shaped boots and disposed on the ski. 12. The apparatus of claim 10, wherein the one or more straps are secured to the side walls of the L-shaped boots. 13. The apparatus of claim 1 further comprising a brake block for locking a wheel of the wheeled vehicle against a frame component of the wheeled vehicle. 14. The apparatus of claim 1 further comprising a brake lever band for continually activating a brake lever of the wheeled vehicle. 15. The apparatus of claim 1, wherein the apparatus is attached to a front tire or wheel, a rear tire or wheel or both a front tire or wheel and a rear tire or wheel. 16. A method of using an apparatus for increasing the buoyancy of a wheeled vehicle, comprising: providing the apparatus of claim 1;mounting the apparatus on the wheeled vehicle; andoperating the wheeled vehicle. 17. The method of claim 16, wherein the wheeled vehicle having the apparatus mounted thereon is operated on snow, water, sand, plastic, metal, a waxed or lubricated surface or combinations thereof. 18. An apparatus for increasing the buoyancy of a wheeled vehicle, comprising: a ski to be disposed under at least one tire or wheel of a wheeled vehicle;a pair of L-shaped boots, wherein each of the L-shaped boots comprises a bottom wall secured directly or indirectly to the ski and a side wall substantially perpendicular to the bottom wall, wherein the side walls of the L-shaped boots are configured to laterally constrain the tire or wheel of the wheeled vehicle; anda pair of tie downs positioned fore and aft of the L-shaped boots and disposed on the ski for securing the wheel and rotationally constraining the tire or wheel of the wheeled vehicle. 19. An apparatus for increasing the buoyancy of a wheeled vehicle comprising: a ski to be disposed under at least one tire or wheel of a wheeled vehicle;a boot having a unitary structure including a bottom wall secured to the ski and two side walls substantially perpendicular to the bottom wall, wherein the side walls are configured to laterally constrain the tire or wheel of the wheeled vehicle;at least one mounting bracket positioned between the ski and the bottom wall of the boot, wherein the mounting bracket comprises holes configured to independently align with the ski and the boot; andat least one tire block pin for connecting the side walls to one another to increase rigidity of the apparatus and to rotationally constrain the tire or wheel of the wheeled vehicle.
