Tires R4 on the Front/ AG in the rear?

[Votum]

Greetings,
I am looking to get a little more traction out of my DX55 when pulling the larger disc. I was wondering about just sticking AG tires on the rear, and try saving some money that way as opposed to buying four new tires for all the way around. Is anybody doing this? How is it working out?

Thanks

Not that combination, but we ran Ag on the front and turf on the rear and Industrial and turf. We just made sure the circumference was compatible.

I've got R4s all the way around, the tractor came that way. The fronts are OK, although I haven't tried then out in snow yet. The rears are terrible I've had them spin on moderate slopes. As far as being easier on turf, I can't tell any difference between them and the Ags I ran for years and I don't belive they're gonna' do too well in snow.
I've looked for 24" Ags with out much luck.
If I've got to go back to putting chains on a new 4wd tractor just to operate in the snow Massey is going to be hearing from me.

AG (R1) and R4 are going to be hard to match up for correct circumference so ratio will be correct for the gearing. Besides that Ags are much more narrow than the R4 and would need a rim change also. If you can spring for Ags on the rear, the fronts should be cheap comparatively speaking but nothing made from oil is cheap now. That is why you need to get what you need when you buy as it is just way too expensive to swap out later.

you cant run R1s an R4S togather it wont work.you either run 1 or the other the choice is up to you.

I'm not following you. If you use ag rears of the same circumference as the R4s you're taking off why would there be a problem? My dealer tells me that I have about 5% wiggle room.

What ever you end up doing just be careful to select the proper diameter to avoid binding the driveline.
Idealy you should be able to run straight down a road without driveline binding and engage & disengage FWD easily.
You can fine tune the ratios by adjusting the tire pressures.

The fronts usually turn about 5% faster than the rears as that is the way the gears are set. IF you can find an R1 that matches the R4 on the rear AND will fit the rim then you should be ok. There lays the big IF. I know that they make some wide low profile AG tires but they may or MAY NOT be the correct cicumference. If you get it wrong, then you can expect to pay dearly for a front differential repair. Please dont try to be pennywise and pound foolish in your assessment of the situation when selecting tires and get "close enough"

I say go for it. Then post back on how the dealer and manufactor are denying warranty repairs for the torn up front differential and other drivetrain damage. I would add wheel weights and liquid ballast to the tires currently on the machine. I don't think you would experience wheel spin then.

As mentioned earlier, we ran mixed rear front installed by the dealer when bought new in 1987 and kept the same combination up until this year; LOTS of hours and no mechanical issues.
