I'm assuming you mean 'no flat' tires. I got them from Wal-Mart, but haven't found them recently... Did the 'slime tubes' replace the 'no-flats? I'm going to have to be very careful with this cart... (It's a client's cart.) as we have five acres of sand and mesquite trees (which have thorns). I keep getting them in the soles of my shoes... I'll be walking along, ground driving a horse, and get one in my sole... I gotta stop and get it out and it usually means I have to go inside to pull it out with tweezers... Arggh! Really disrupts the lesson (that and having to go pee!) lol!
