R1's on a 335?

[BATTY54]

Anyone have R1 tires on their Bobcat? I wanted to see one befor biying but the dealers do not seem to have any. Pic's would be great. Mainly looking at the 335 shuttle shift.

On a chance, anyone have the 335 shuttle? Opinions how well does it work? I assume there is a foot throttle, I use mine on my JD keeping it just above idle stop to shift F-R non shuttle.

Can't help you on the R1's

The SST's are nice. Throttle pedal on the right foot, 12 forward, 12 reverse gears. (low, medium, high ranges, 4 gears per range).

I have R1's on my 335HST and think they're great tires. I will say that they're quite aggresive. I wouldn't drive on a nice yard with them, especially when wet, but you could probably say that about R4's too. I have them filled as well.

I do quite a bit of "playing" in the woods, clearing trails, knocking trees down, ripping out stumps, also maintaining about a quarter mile gravel driveway that goes up hills and down. I haven't had it through a winter yet so I can't comment on the snow traction but I am looking forward to it, a set of chains may be in my future.

When I bought mine they didn't have any R1's either so they delivered it with R4's and ordered the R1's so I got to drive it for a couple weeks with the R4's then they came and took it back to the dealer and swaped them out. Worked for me.

As for the SST, mines an HST so can't comment on that.

Heres a couple pics, I tried to include a video but it wouldn't upload.

Perfect! ... Can you give us a comparison between the performance and feel of the 2 types on your tractor. We dont often get a chance to hear a direct 1 for 1 comparison.
Thanks!

Sure. There is a big difference if you're doing any driving on roads (or paved driveway) the R1's are quite bouncy but I do all my driving on dirt or gravel so thats not an issue (to me).
I will say that the R1's are way more aggresive and certainly can and will dig holes in the ground when pushing/pulling, even in relatively dry ground. I never take my tractor out of 4WD and use the diff lock quite often and now I keep the back blade on to resmooth what the tires just dug up.
I had the R4's for about 2 weeks and did some stump pulling and such and the R1's just seem to get better traction, that said, I had my R1's mounted at the widest they can go because almost all my terain is shall we say uneven so stability was a concern and I also had them filled which I believe has the biggest impact (R4's were not filled).
I could be wrong but I beleive the R4's are a thicker/stronger tire (rated higher) but for me the R1's was the way to go because of my particular driving conditions. The R1's are also a taller, thinner tire.

Thanks for the pics Steve, that was what I was looking for. Looks like they increase the ground clearance a bit too. You are right on the R4 being a tougher tire but I want the traction of the R1's

Steve, it looks as though your rears are too hard. Fronts pretty much have to be with FEL, but rears can be in the 10-15psi range so they can put a little more tread down. The only time my filled tires look like those in your picture is when Iv got a full bucket and no rear ballast.

Note that Bobcat-branded tires are called General Purpose and All Purpose,
and the AG tires are quite substantial. The front AGs on my CT230 were
6-ply, instead of the common 4-ply tires. Note that you pay less for the
AGs, too. Traction is MUCH better.

It seems that Bobcat automatically puts the IND tires on their tractors,
possibly due to their construction (SkidSteer) heritage.

Larry, really?? Heres what I have...
fronts- the manual says 78psi, the dealer recommended 70psi, on the tires it says 60psi, I have 70psi in the front. It says "Bobcat All Purpose R-1" and 10 ply on the tires.
Rears- the manual says 32psi, the dealer recommended 30psi, on the tires it says 32psi, I have 30psi in the rears. It says "Bobcat All Purpose R-1" and 8 ply on the tires.
Are you saying that letting some pressure out of the rears will give even better traction? and not harm anything? That makes sense putting more tread down just concerned with not having the "tire" correct pressure in them.

You have heavy duty R1s. Are you sure those are "correct" pressures or pressures recommended for the max rated load? The HD fronts are good cuz you really need to run regular AGs up to their MAX or a little above for heavy loader work. You have even your HD fronts well above the max -- the 45-60 range ought to be plenty, adjusted dependant on loader work. The rears should be fine in the 15-20 range. It would probably be abusive to go below because a HD tire does not put up with significant flexure as well as a lower ply carcass will. A standard carcass Ag is quite happy with a bulge from a good flat spot on the bottom. A HD one less so. Two bars or a little more [3-2] fully touching on both sides is the rule of thumb for best traction. I think the 15 - 20psi range will do that for you and the tire will be healthy esp if you adjust pressure to give the 2 bar range rather than the 2-3. ... Youll get better traction and ride. I think itll be a lot more pleasant to operate, and Im sure youre having fun already.
