Need a dealer for 4110 Parts !

[Dougster]

To answer a couple of your questions - one & all. My front tires are the Titan 10-ply, 12-16.5 NHS (skid steer tires). The rears are Titan 17.5-24, 8 ply R4.

Galen is right about the "new" rear tire size... 16.9x24-8 on my 2004 4110. According to the Titan Tire corporate website, the rolling circumference of your rear tire is 145 inches while the rolling circumference of mine is 153 inches. Funny how that works given the seemingly contradictory tire designation (i.e., 16.9 vs. 17.5). The new (16.9) tire is also 20 pounds heavier, 0.3 inches wider and can carry an extra 480 pounds of load... apparently due to 2 extra pounds of specified inflation pressure.

So if the new rear tire size is perfectly correct in terms of front vs. rear travel ratio... and if all other things remain equal... it means that older 4110s are, indeed, pulling way too hard with their front tires to the tune of 8 extra inches of attempted travel per single rear tire revolution. In other words, Nightrain1 was dead right in his observation... and I'll bet the axle forces are much higher with heavier FEL loads holding down those front tires that will want to be turning faster than the rears will allow. It does seem that Mahindra had the pressure thing backwards unless the point was to try to *skid* those front tires more easily with very high inflation. It obviously shouldn't have been an attempt to "grow" the front tire's rolling circumference.

Not to be intentionally funny... but is that why we have skid-steer tires on the front? Because they literally have to skid so much?

I found this web posting which was derived from Goodyear tractor tire handbook concerning radial tires and correct inflation pressure. I'm not sure if it covers this problem that we have been discussing but some others might find it interesting reading. It seems I keep learning more about new things everyday, never heard of the term power hop before.

Interesting read, but my tractor tires are bias ply, not radials. Are any of the newer Mahindras (post-2004) coming through with radials?

Friends,
I am not sure if this helps but for optimum traction you want the front wheels to turn 1-5% faster than the rear. (Per Titan engineering dept) also you are more likely to break a front axle when using a loader if the tractor is not balanced with ballast. (You put more load on the front axle if you have not loaded the tires or otherwise balanced the tractor.)

No doubt the front wheels have to pull harder or you would be hard pressed to turn the tractor in 4wd, the backs would just push the fronts straight forward. On the other hand, I hope my little geared 3510 is closer to 1% then 5%. Just think if you went a hundred feet with 5% ratio up front. That would mean in the 100 feet, I would had to drag the back tires 5 foot over the 100 foot trip. I guess this is why they tell you not to run 4wd on hard surfaces like the roads or highways.

This is my first experience with a 4wd tractor, I did'nt realize the importance of the front drivetrain in determineing just how much tractor you have. You're only as strong as your weakest point and when I have the fel full of wet clay dirt, I can see that front axle has about all it can stand.. I am so glad the Mahindras are built beefy.

As far as Skipmarcy, if I was you sir, the next set of axles I put in there would be treated and or, I would opt for the new back tires that are standard on the newer 4110's. That is a bum deal you have and obviously there was a little problem or they would had not changed the set up.
Whatever happened to the Mahindra rep that used to frequent this board?

I was thinking the same thing. I can see a front bias of 1%. God only knows how much front bias I've still got left with the "new" tires... but having over 5% more front bias with the old (17.5) tires can't be a good thing.

That would mean in the 100 feet, I would had to drag the back tires 5 foot over the 100 foot trip. I guess this is why they tell you not to run 4wd on hard surfaces like the roads or highways.

I never run 4x4 on hard (i.e., paved or concrete) surfaces... but in your example, wouldn't the massive rear tires simply restrain the front tires and cause them to slip? I suppose it would depend on your FEL load at the time vs. what counterweight you had on the back end. In my case, the 509 BH virtually assures that any tire slip will occur up front.

As far as Skipmarcy, if I was you sir, the next set of axles I put in there would be treated and or, I would opt for the new back tires that are standard on the newer 4110's. That is a bum deal you have and obviously there was a little problem or they would had not changed the set up.

Those new rear tires list for $571.52 each. Plus shipping and installation I'll bet. That's a lot of spare axles at $42 each. If I could change one in 15 minutes (instead of 15 hours) and it only happened to me once or twice a year, I too would be inclined to view this as an ongoing maintenance issue/expense. It is a bum deal... no question about it... but at this point I wouldn't spend a small fortune to reduce the frequency of replacement unless I really needed those new rear tires. On the other hand, it might make more economic sense to find a slightly smaller diameter set of front tires.

That is alot of $$$, 571 a piece. I thought they would be cheaper then that since one member claimed wheels and tires for $1400 all the way around...

I don't know if Mahindra has a whole goods program for ordering tires or not but that would be the least expensive way to get new tires and wheels if they do. That is when the dealer orders them when new tractors are ordered and they come in with those new tractors. The parts department doesn't have anything to do with them and they are mounted and ready to go when they come in. At least that would be something to look into.

I believe that particular gentleman installed aggies on his 3510, not industrials. Not sure what brand.

My local dealer quoted me right around $200.00 each for brand new skid-steer fronts... so that at least puts us in the right ballpark. Plus I quoted manufacturer's list price. I'm sure many dealers discount.

I have a 2002(thanks Dougster for the PM), 4110 with over 600 hrs, 300+ of heavy loader work, I also have the same tires as skipmarcy ( 17.5L x 24 Rears ) , but all four are "loaded with Calcium", I will increase rear tire pressure and lower front tire pressure as a precaution.
Thanks all for the info
