I want I buy new valve caps for my tires. Are motorcycle, bicycle and automobile caps the same?
For the most part. Motorcycles and cars and some bicycles all use Schrader valves. Some bicycles, however, especially road bikes that have a narrow rim use a Presta valve which is narrower.
There are two types of common valve stems, Schrader and Presta. Passenger vehicles and motorcycles pretty much exclusively use Schrader valve. Bicycles, depending on tire type, could have either.
