Michelin Axiobib tires? « Thread Started on Oct 16, 2009, 8:05am »
http://www.michelinag.com/agx/en-US/products/product_detail_pages/Axiobib.jsp Does have anyone have any experience/knowledge/opinion of Michelin's Axiobib tires? I'm currently pricing a 200+hp tractor and these high flotation, lower pressure tires are an option. They've even created a new designation for these tires, "IF". I thought that stands for "Increased Flotation" but noooo, that would be too simple, it stands for "Increased Flexion".

We ran those tires back home in Germany on MFWD tractors,and they are just amazing,the best tires by far i have ever run on a tractor,best ride,best flotation best traction,the only thing a guy has to get used to is the fact that they look flat all the time.

Can't say on the Axio's but for Michelins in general I wouldn't have anything else on a tractor. If you are looking for a good gripping tire with exceptional treadwear then Michelins are the way to go. I've got a set on the only mfwd we own and another set on my combine and can't tell that they have seen any use. Still look new!

I agree with all of you that say Michelin is a good tire but I can't believe that only one person here has hands on experience with the Axiobib tires. They've been out about 3 years, are they still that rare?

I think here in northern america its hard to find dealers and support for european tires and many guys are afraid of the price,but from my experience those Axiobibs are woth every cent,when i compare those to goodyears,firestones etc. Its too bad that the big companies like Deere or CNH put those tires on their 4 WDs only on special request.

Hello all,
Before talking about rubber, I will introduce myself. I just registered on this forum and this is my first post. I am from France, but have already seen the other side of the atlantic. I spent a couple month in Iowa, and soe other months in Manitoba, Canada. I started to look at this forum almost daily about a year ago, and I just decided to sign in. Now let's talk about axiobib.
Don, IF stands for "increased flexion". The first time that this kind of sign was introduced was for the Xeobib. they are called VF for "very high Flexion". They are made for lower power tractor, wheareas the Axiobib are for the high HP.
Don, if you are looking for these kind of tires, that means that you don't have the row crop constraint, correct? If so, looking for such tires is a really good thing. From what I saw other sea (well ok, on your side), 99% of the MFWD tractors are equiped with row crop narrow tires (480 max, 520 in some rare cases). I have to admit it is necessary for row crop work, but not all of the tractors suffer this constraint. Again from what I read on this forum, and what I heard talking with the guys in the fields, Agribib ties are seen like the best tires possible. In Europe, large tires are more common, in fact very few tractors are used for row crop applications. The agribib tire is a basic low cost tire for us, but going to an Axiobib is a totaly different thing... The Axiobib is a high volume tire. Volume means carrying capacity, and so big footprint, low compaction, and good traction. The advantage of the axiobib is its capacity to be run at a lower pressure than other tires. And you have to know that the pressure in your tire is more or less the pressure on the soil. The Axiobib has a very high side, in fact the higher available in the industry. having a big wheel is useless, what you need is air volume to carry big loads at low pressure. Lets take an example, and make a comparison between a single 800/70R38 Axiobib and two 480/80R50 Agribib (duals). Both are group 48, so 2.05m in diameter. This is the highest possible on a 8R Deere or Magnum.
For this I took a 350 engine Hp tractor (8530, magnum 310...), and logically said that to transfer all the power to the ground at low speed it needs 50Kg/Hp. Then I calculate what would be the weight of the tractor, and after that it is just a simple job of tire saler. Note that the weight of the tractor is impressive, 17500Kg! None of the tractor I saw ather sea were ballasted so much, and this explains some traction issues.
So, figures speak on their own, the single axiobib will be run at a lower pressure (25%), giving a larger footprint and so 25% less compaction. For me it is extremely important in soils that are sensitive to compaction, when working in wet conditions. One more thing, an axiobib at this pressure will run extremely smooth, compared to row crop tires. When working at high speed on rough fields, it counts a lot, and will prevent power hop...as well as back problems!
So this is all for y first post, I hope it was clear enough, I know my english is not perfect, but I do my best to be understood.
Don, if you are looking for these kind of tires, that means that you don't have the row crop constraint, correct? PV
Welcome to the forum PV. You are correct, no row crop constraints. With the input here I have no doubt what to order. If one is going to put Michelins on regardless it doesn't add much to go to Axiobibs. Thanks to all for your input. Want to hear something funny? As I was typing this I got an e-mail...from Roger Plemmons at Titan Tire. Showing 10 pictures of Titan 800/70R38 Duals on a JD Combine. What are the odds?

I have never seen the Axiobib but as far as I'm concerned Michelin's are the ONLY ag tire to buy. This is coming not from a farmer but from an ag salesman that has to look at used tractors with there used tires every day. I'd pay double for Michelins as you could get more than double the life compared to goodyears where I'm at....... I despise Goodyear ag tires and trying to value tractors with them on. Even the ones with good lug left are so checked up that people want to pay less for the used tractor. It's a lose lose deal.

As a dealer, we find that on anything over 100hp, guys around Southwestern Ontario almost always want Michelin tires. Deere does not offer Axiobibs on many new tractors, but we have a new 50K 7930 here right now with 710/70R42 Axiobibs on it. Most Michelins from Waterloo are Agribibs, Omnibibs or MachXbibs. Deere really drags their feet when it comes to Michelins, as 80% of the buyers in the US don't care about Tire Preference, and just as happy with a Goodyear or Titan as they are with a Firestone or Michelin. Around here, Goodyear and Titan are bad words. Firestone is an ok 2nd choice, Michelin is tops. Deere has started offering Continentals from Waterloo too, as they have had a hard time getting enough Michelins to fill demand for the past year or so (Michelin has failed to meet some tire delivery dates to Waterloo, giving Deere a bad taste for them). On Combines, Deere offers Michelins only for exported machines to Europe, they don't think NA farmers will pay the premium for them, but I am certain they would sell well. The 2011 combine pics have shown it with the 28L-26 Michelin equivalents (750s) on the back, so they are obviously starting to look at this as weight becomes a bigger issue.

Why do I think you are gonna be buying a red tractor?
In fact, any color he wants. I am not sure, but I guess the tractor looking at must be a Massey Ferguson 8600 serie (or a yellow painted one, or orange painted. ) One more alternative I see would be a fendt, but I doubt, they are so rare in NA...
If going with any of the AGCO brand, are you considering the best tire possible: 710/85R38? This is a 2.15m in diametre, available only in the AGCO brands, since John Deere and CNH don't offer so high tires.

Another vote for Michelin! Our little 6430 came with Continentals and they are total crap. Just got it back last night from a full tire swap. Tires were separating like they had been cut, what junk. Have a buddy from college that custom harvests and he just swapped out Firestones on his 09 9770 (250 hrs) and his 08 9770 (? hrs) in September. Sidewall issues. Kind of weird, don't hear much bad about them usually...
You would think GY has been in the biz long enough to know how to build a decent tire.
Goodyear isn't in the biz any more. Titan bought the ag tire side from Goodyear about 3 years ago IIRC, and also bought the rights to use the Goodyear name on ag tires. Titan is now trying to buy Goodyears ag tire plant in France.
we have a new 50K 7930 here right now with 710/70R42 Axiobibs on it.
Are you sure on the size? Build your own only lists 650/85R38's in the Axiobib tires. Looks like they're not offering Axiobibs in the new 8 series tractors at all.
Since it's still dark there it's like you were waiting for that question. Wonder why I only see the 650/85R38's Axiobibs in the build your own? 710 Axiobib's definitely not there.

Hi Don we run a fendt 933 from pentagon farm centre and it has michelin axiobib 800/70 r38's We absolutely love thm and find little need for duals as they give great flotation at 8 psi we run them at 14-15 psi when hauling heavy loads. We travel about 30km from farm to field at 55km per hour. we find they have great wear and would reccomend them anyday. Our smaller fendts had agribib tires which were also good. I hope this helps ya and good luck shopping
