they are great for trying tires out on the track and if you like them then take the set and glue em up! If they don't work then bolt in another set. that wayyou are not spending gobs of money on rims and tires, and if you want to get rid of a set of tires, then ebay is your best friend, selling tires online only works if the buyer can choose what rims to get, and finding used tires that have never been glued but are cheaper because they were used, is a good deal unto itself
