Anyone having problems with flat tires on sun mountain cart?
Fixing the tire is just like fixing a bicycle flat. repair. Remove the tire, take out the tube, find the hole, and repair it.
You might also try the self-sealing bicycle spray that can be inserted into the tube, if flats occur very often.
Personally, I switched to the Bag Boy easy-fold cart with non-pneumatic tires. It rolls nicely and no more flats.
