my husband & i just bought a 1981 prowler, not in such good shape. so we are fixing it up. tires are the wrong ones we were told, but who really knows. i can't seam to find the ones that are on the trailer now. p165/80d13. is there some place i could go & find out if these are the right ones, with maybe the vin #? books have very little info written in them. thank you if you can answer this for me! sam I was told by one person that i may be able to use a p175 in it's place. can anyone else confirm this!
