​​Tiger Wheels is a lesser known diecast toy maker located in Puerto Rico, with cars made in China.  These cars feature all-metal bodies and chassis and are intended for racing.  The wheels are similar to the Johnny Lightning racers edge wheels.  I have six cars (see picture).  These cars are very heavy with each one exceeding 70 grams!  The white '69 Camaro is the best of the bunch for me and nearly broke into the Good Speed level.  Most of the rest are near competitive.  The challenge are that wheels don't spin easily, even after some warming up.  I would expect that with some dry lubes applied, they might come to life.
