This DWT 850x6 QMA rim is built for Quarter Midget racing, not a full-size sprint kart or kid kart, and the 4.0+4.5 offset sets how far the rim sits in or out from the hub so track width and scrub stay where the chassis was aligned. Racers pick it up as a replacement or spare when a rim is bent, cracked, or the offset no longer matches the rest of the set.
