What year 5700? I have a '55 6500,and it uses 10 bolt Budd's,(2-piece,with ring). These are acceptable,as long as they're in good shape! There's a '56 6400,(on the same farm),and it has 6-hole,6-bolt Firestone RH-5's,which,are considered dangerous. Truck tire guys won't touch them! We just found a set to fit my buddy's bus(6-hole "Widow-Makers"),but they're 19:5's,(radials),and he wants to go with 22:5's,but they're the 6-bolt pattern! I'm not sure the 6-bolts are available in the 22:5's. As for the tires,the 7:50X20:00's,are hard to find,compared to 8:25's,or the 9:00's. All three sizes are compapible for the same rim. I use 8:25X20:00's,on the steers,and 9:00x20;00's,on my drives. The taller rear tires gets my speed up to a comfortable 55. Call Tire Associates. I think they have a branch in your area. Baraboo close? S2502 County Road BD Baraboo,Wis. 53913 Phone:(800)233-6943.(608)356-8880. They mounted my tires for a fair price,and were careful with the new paint! They didn't charge much to get rid of the old tires,either.
