Basically
Whatcha got? Do you like it? Why?
Im beginning my project
Im leaning toward all position for the cost difference, anyone have a argument against?
My first advice is, don't buy tires until you really need them. If you are not planning on traveling far, or for long distance to get them heated up, wait!
Plan on only about 7years on date code. If you are in the beginning of your build, 7 years seems to go by quick. Just ask me how I know. I'm on year five since putting tires on, and already thinking of my next set. Even though mine still look like new.
If you really are ready for tires, here is my experience. For the line trucks at my work, we always put on name brand tires. Firestone, Goodyears, Michelin. I don't want to take anything away from them. On my own bus, price dictated alot. For a vehicle that only sees 3-4000 miles a year I knew I would never wear out a set of 11r 22.5 tires. Age will kill them first. So I went with Samson front steers (equal in both steers). I really hate to admit it, and won't to work, that they have been better then the last two sets of Michelin's put on a Line truck. They ride great and are alot more true to round, then the Michelin's we had to replace for being out of round. Since those two bad "new tires" we have put on Firestones with good results. My next set of steers will probably be Samson's again. I did retreads on the rear. I will not promote them. I did loose a cap on one, but felt it coming before it did much damage. At $200 mounted, retreads are cheap. I'm still thinking about what I will use again on the drives. My favorite pattern is the old Goodyear 164's, Quiet and fairly aggressive, but were way out of my price range for the bus. I like a more aggressive pattern like Eastcoast on the drives. But I also like to go places off pavement. If it never left pavement, I would do All positions for sure. Makes alot of sense to use them. I haven't looked into it yet, but if Samson makes a decent aggresive drive tire, that is reasonably priced, I will give it some serious thought on my next tire too.
