I need some very small tires that are rounded like those on a street bike and have tread for high speed and good grip on pavment.They need to be 4-6 with rims. There will be 2 or 3 of them supporting no more then 300lbs.
could be off balance or maybe something as simple as mud in ur rim
Is it driveable? Does it do it when you turn or when you go over bumps??
