Bierman, i had similar rims on my 48 and the greater problem was finding a tire shop that would touch them. Ended up buying some dexter trailer rims ( I believe it was suggested by someone else on this site). Added some hub cap clips to reuse stock hub caps. I got Firestone whitewalls so still had to use tubes. I dont drive on highway as my top speed is about 45mph down a hill and put less than 100 miles on in a year. I have heard some gripes about putting a trailer rim on a truck but it works good for me.
