8-17.5 is the one tire size but it's almost non-exsistant. . . 8-19.5 is still around tho knowen now as 8r19.5. . . all the tread esign's they have now for that size are junk. . . . if it's 2 wheel drive run 8R19.5 good year G633's on the rear and a 245/70R19.5 on steer's if you got dual rear wheel's. . .front tire's will be a bit shorter but alot wider will give the truck a tough look. . .other wise on singel rear wheel truck you should use a set of 265/70R19.6's all around. . .
if you find any 8-19.5 biasply Mud tire's let me know i'll buy 60 of them . . .
the tire's i'm looking for are :
Firestone super all traction.
General super all grip.
Goodyear custom extra grip.
run the 19.5's they'll last you a life time. . .
17.5's are about exstincted. . .
