710/70R38 vs 710/70R42 vs 800/70R38
Wondering if anyone had any experience with different tire/rim combinations. Basically I understand that the 800s are the best of the bunch, but why are they mounted on 38' rims? The increased air area allows more weight to be carried with lower tire pressure, however Deere equips its 9430s with 710/70R42s as opposed to the 800/70R38 on the 9530 and 9630, and changes again to 710/70R38 on the 9330. Wondering what the reasons are? I would expect the 38" would allow the best ride, most weight borne, and least air pressure however would imagine they cannot pull the heavy weight as well as the larger rim size of 42". As well, is there a big difference between the group 47 and group 48 tires?
Any comments or experience is greatly appreciated on this topic.
I suppose the R42s would be the tractor equivalent of "Twens" or "Dubs" as the kids say these days...
