slink 370864 26 I was wondering... either
I was wondering...
Why do some people turn the front tyres on a MFWD tractor in "reverse", and i see the same thing on some combines, but on combines rear tyres are "reversed"...

Some people told me because of the reverse traction, some because of less tyre wear on hard surfaces (tarmac, concrete...). Which of them are right?

Please help me, because I couldn't find satisfactory results...


ONLY ENGLISH PLEASE

Thanks in advance!

Re: I was wondering...
i heard it is for more traction to drive back.

Re: I was wondering...
if you reverse them, they wear less, so you can do more work with the same tyres
also, it's nice if you have a frontloader, i don't have to explain that;-)

Even here I get two different answers...

This is funny... Where ever i asked, nobody could tell me the exact reason for reversing front tyres...

I can hardly wait to see how this thread will end...

in this part of the world tyres are reversed to reduce wear on hard surfaces. but it reduces traction so is a comprimise. rubber isnt cheap...

Hi

from what I heard it goes like this. Usually the reversed tyre is unpowered. On a powered one you want to have the thread the normal way to get the power to the ground. The unpowered one however, is easier to push or pull with the reversed thread. The powers are just opposite. Hope you can understand what I'm trying to say :-[
Also a lot of people say they have less bouncing. I'm not too sure about the better ability to back out. It might be handy with a front end loader.

Re: I was wondering...
@ Richard: I thought so myself. I bought my first MFWD tractor half a year ago, and i would like to find out why do people reverse front tyres.

My tractor has front wheels too much V positioned, so it eats outer profile very fast so it's all the same for me. It's only half a year old, and the front tyre wear is very much noticable so i'm a bit worried about that. I can't straighten the wheels so front tyres have the same load and the equal wear on the whole tyre width, and because that all the load is distributed only on outer sides of each front tyre... :-(

@Martin: I understand what you are trying to say, but I doubt there is less bounce, because bouncing is caused with the wrong pressure in the tyre, not the way it's directed...

Re: I was wondering...
It is for many reasons. The front tires are placed in a ^ way. they drive towards each other. When you do much of transport, one side of the tire will be more worn then the other side. That's why they replace them from left to right, but then they can leave them in the same direction. just put the tire from the rim and change them. On the road (so when you drive without the 4x4) your front axle is driven by the road, and the driven axle, is driven by the motor. Thats why they reverse the direction of the tires in front. They say that it also helps for tractors in ground transport, that it gives more traction when driving in reverse, for tipping... I hope you understand it all. My english isn't that great:-)

Re: I was wondering...
ey, another thing is that they wear out nicer if they are mounted backwards, you`ve probably seen front tires that were worn out wrong, (worn out more in the middle) this doesn`t happen when they are mounted backwards

Re: I was wondering...
@Cedric: When I said V positioned, I meant that in a way when you look the tractor from the front, the tyres are in a V position. I understand what are you saying, and i think my tyres are straight (not driving toward each other) I can regulate that with a rod that connects left with the right wheel.

@ Marien: Yes I saw tyres worn out like that, but that happends only when your wheels are vertical, and tyres hold the load with their full width. I didn't know that reversing tyres can prevent that...

Re: I was wondering...
you have three answers, and as far as i know, they are all true:-)

we have 2 tractors, both mfwd, and one of them has a FEL
the one withoud FEL does a lot of transport, so the front tires are reversed to wear less, and-like marien says- to wear nicer. The tractor with FEL has also reversed tires, so if you get a big bale(or anther heavy thing) you have more traction backwards

OK, thank you all!

hmm, what do you mean with vertical tires?:-[

Re: I was wondering...
Like the picture shows. By vertical wheels i mean the red lines, but my front wheels are positioned like the blue lines show, so front tyres hold their load only with outer sides, and are wearing very very fast because of that.

When we bought the tractor, first 40-50 hrs were made in transport, and that can be seen on very fast tyre wear on the front end...

I asked about that at my dealer's, and they say it's normal :-\ ...

So, if I do a lot of road transport with my tractor, i will need to buy front tyres every year or two :-( ...
