Today, automobiles exclusively use pneumatic tires -- those filled with air -- but this was not always the case. Earlier automobiles rolled on tires of solid rubber until people realised that pneumatic tires absorb shock more effectively. Solid tires may be desired as a means to avoid the hassle of flat tires, but they are not recommended for use with automobiles. If you wish to have solid tires on your car or truck, however, you can convert pneumatic tires into solid tires.
- Skill level:
Things you need
- Tire, on rim
- Utility knife
Make sure the tire is deflated and securely attached to the rim.
Use utility knife to cut the valve stem from tire and, where the valve stem was formerly located, a hole large enough to insert the stem of the funnel.
Use funnel to pour wet cement into the tire, rotating the tire after each funnel-full of cement to ensure as equal a distribution as possible. Stop filling when you believe the tire is full of cement.
Allow the cement to dry with hole side facing up.
Check the tire after the cement has dried. If there are any pockets of air, repeat Steps 3 and 4. If the pockets are isolated from the initial hole, cut new holes to access the pockets for filling.
Tips and warnings
- Solid tires are ineffective at absorbing shock and, as a result, using solid tires may damage a vehicle.
- Solid tires will not distribute the weight of a vehicle effectively either, possibly resulting in damage to roads.
