PCT No. PCT/US81/00241 Sec. 371 Date Feb. 25, 1981 Sec. 102(e) Date Feb. 25, 1981 PCT Filed Feb. 25, 1981.A tire cooling system (10) for a vehicle having a wheel (12) with a tire (14) mounted on a rim (16). A heat transfer device (22) is positioned in a central cavity (18) defined by said rim (16) and tire (14). A first fluid (20) is contained in said central cavity (18) while a second fluid (25) is circulated through said heat transfer device (22), said second fluid (25) being in fluid isolation from said first fluid (20). Said second fluid (25) is circulated through a rotating wheel seal (28) to a heat exchanger (38) and back to said heat transfer device (22). Use of an intermediate heat exchanger, such as said heat transfer device (22), permits use of oil as said second fluid (25) permitting leakage from said rotating wheel seals (28) to be contained by and made up from said final drive sump (42). Oil has, of course, a deleterious affect on rubber. Through use of oil in an isolated cooling loop, relatively simple liquid cooling with an external heat exchanger (38) is achieved.
