@ Rishab N: Those Team Losi 1.9 Mini Rock Crawler Tires will fit the Lego 44772 wheels just fine, since they fall within the recommended 37-48mm width range. They have an Outside Diameter of 3.78" (98mm) and a width of 1.48" (37.8mm). The price you found is SUPER LOW, so get a set!
As stated on this Eurobricks post, 1nxtmonster used two pairs of Team Losi "1.9 Mini Rock Claw Tire, Blue (2)" on his Lego Technic
, and discovered that they were VERY INEXPENSIVE on Amazon.com and fit on the standard Lego 44772 wheel. They normally sell for a lot more on the Team Losi website.
