People who have not been in the tire business for a long time get paranoid when they see these wheels. Stay away from car tire shops is my advice. Tire manufactures like to play it safe and don't recommend mounting modern radials on these rims. They have nothing to loose, its a very small market today. Radials have been mounted on 2 piece rims ever since radials were introduced. These 2 piece rims are more than strong enough to handle and additional side loads radials put on rims. The older solid 16" 17.5" and 19.5" have a different construction and are not as strong as the lock ring style wheel when used in severe service. The ring that doesn't connect is a Goodyear wheel ( '65-'67), the continuos ring is a Firestone wheel ( '68). An easy swap is replace the Eaton 4.57 ratio pumpkin with a 4.11 Eaton pumpkin. P>S. Always carry a good spare tire, you don't want to search for a truck tire dealer the day you get a flat with 2 piece wheels.
