Does any one here run all position tires on the drives? Im going to change tires before to long and going from 24.5LP down to 22.5LP. I only haul about 30,000 max load and 2-10k on return. Im thinking about do a six tire configuration with four on rear axle and two on front axle since I don't need eight tires why waste the money. I'm for sure going to use all positions on the front axle but wasn't sure if I would get enough traction using them on the back. I run regional IL,WI,MN drop & hook dry van.
Have a Tire question.

If your changing size you really should do all 10 tires. If you have mix matched on your drive your going to have a problem on your hands, and they will wear out fast anyway.
-
You will have to do all 8 because of the difference in heighthow from 24.5 lp to 22.5 lp. If you don't get ready to rebuild your rears.

Yes I run all steering tires on the whole rig.

I do not think he is talking about mixing sizes, just deleting 2 tires on the front drive, one on each side. That will work, but not sure I would do it. Have seen it done, but traction can suffer if needed in bad places.
You can run all position on drives, I have done it. Again, traction may be affected.
Might be OK in your situation, but not in most.MJ1657 Thanks this. -

Yes I was just going to delete two tires from front drive axle and all will be 22.5LP

I wouldn't mix a lug and a straight tread on same dual. They will be fighting each other for control all day. Not good for tires or bushings. Far as straight tread on drives I run ry083a Yokohamas and very happy. They are quiet, run cool, great for traction, don't pick up rocks like a lug, and will not pack with mud or snow like a lug.

I've seen busses and RV's with a tandem axle set-up where one axle has duals and the other is only a single wheel. Not sure if they are single screw/dead axle or if they are twin screws, though...never got up close and personal with them. The one concern I'd have is being overloaded on the SRW axle, since the suspension will keep the weight evenly distributed between the two drive axles. In other words, if running a SRW setup on one drive axle, you may as well do it on both. If you'd be overloaded with SRW on both drive axles, you'll be overloaded on the one SRW axle even if the other axle has duals unless you modify the suspension to favor the DRW axle...but then you run into other potential issues in regards to axle weights not being evenly distributed within the axle group.
Perhaps a heavier rated tire which would allow you to get by with SRW on both axles would be a better way to go? 16 ply (LRH) 11R24.5 tires are good to 7160/single, which gives you 14,320/axle and 28,640/tandem if used in a SRW manner. In other words, you'd get about 4.25 extra tons over a 2-axle tractor...but some of that would be eaten up by the weight of the extra drive axle and the works.
You'd probably be better off just getting a single screw truck, and if you REALLY need an extra axle, add a tag that can be lowered when your weight requires its use, but can be raised when it isn't needed.
