Hi Looking4new, I don't mean any sort of hijack to your thread, but I've a similiar question that relates to yours and maybe we can both get an answer.
Roy, What does someone do if their tires don't have the "recommended" air inflation posted on their tires? Perhaps Looking4new is like me - my tires don't state that information; neither is it to be found in the service/operator manual. I've simple been watching my tread pattern to ensure that it gives a flush fitment. But, like Looking4new, I'd sure like to know the proper inflation pressure also! I loaded mine myself with plain water because I have no fears of freezing here, but I've often wondered - after - what should my proper pressure be? Info on my tires follows -- Rears = 12-16.5, HUNG-A, 6 PR Nylon, Load Range C, HS610, Tubeless, Made in Korea...Fronts = 23x8.50-12, 4 PR Nylon, Load range B, all other info is same as rears. Any ideas you might have would be better than the none that I've got.
Thanks, Greg
