caster tires were made by vppro in the past. vp pro's are good, i wouldn't call them cheep, they are just not as over priced as the older more established brands are, yet. they have a new caliber-ish looking tire coming out soon. the bow-tie looking version i run have about 2 gallons on them and still have about 50% tread, couple blue groove runs but mostly loose practice stuff. their soft compound is like a m2.5 not as hard as an m2 but not as soft as m3 either, they will be a top contender soon.
