Mandrewoid Posted March 24, 2021 Share Posted March 24, 2021 (edited) Hi everyone, I posted here in 2019 about the DMM we acquired. I'm just now a few weeks away from having it fully operational. BUT in order for it to drive through the fields in the conditions we sometimes get into, it needs a bit more rubber. As you should be able to see from the picture, the 680 on the left has 650/75r22.5 on the front. On the back it has 710/65r22.5 which are of course even wider. Ideally I'd have 710's on the back of the DMM too, although they are very expensive tires, and burn up really fast on the road. Also, they are bigger than the 11r22.5's that are currently on. Because the DMM is 6 wheel drive, I'm concerned about damaging my transfer case if I run bigger tires on the back than it was designed to operate with? Does anyone know the standard ratio of the mack transfer case? I'm assuming there is a differential in there, because it says full time 6WD with manual locking. So the differential would allow for the rears to turn slightly slower, but it would mean more power moving through the spiders than it was meant to do. Unless they're just built so heavy it doesn't matter? Second, I have Dayton hubs on the back, does anyone know how to run DUAL 425/65r25 on Dayton hubs I think if it's possible, that could be an affordable solution to put as much rubber on the road as single 710's I know a guy who used to run triple 11r22.5's, but I'm not sure how he did that either. He says he welded the outside rims to the middle rim. But I don't know how he ever got the tires mounted or unmounted after that. Thanks for your wisdom. Andrew. More pictures on request 🙂 Edited March 24, 2021 by Mandrewoid Quote Link to comment Share on other sites More sharing options...
