tyre wear........run soft or hard.

[bigrigg150]

Had some michelin 710 xobibs on a tractor that have worn to not alot after 3000 hours, usualy get at least 5000hrs on previous same tractor same tyres same work load. I think michelin are literally using there well known name to rob people now with there ridiculous prices and chocolate tyres, but anyway thats another story.

What i want to know peoples opinions on is.......I Always got told to pump tyres up hard to stop them wearing...........but starting to think if they are a bit softer, more ground contact, broader wearing area, wear slower? .......what do people think? im talking when on road use, carting silage trailers, dump trailers etc etc

For some reason same brand replacement tyres never seen to last as long.

Some one will be along shortly to tell you to tell you how wonderful cheap tyres are.
Local tyre firm are taking alot off at less than 50% worn as they just won't grip.

I thought Xeobibs weren't meant to inflated above 1 bar (14.5psi), certainly that was the case with the set we had on a 2008 820. They were fine for top work and transport but were basically overloaded with a six furrow plough or big 6.5m hedgecutter on the back and eventually fell to bits before 4000hrs. Fortunately we found a set of "new take-off" MachbibX 650/75R38s on rims with matching 600/65R28s which are much better suited to the tractor and its workload although it doesn't get on the plough these days. The tractor has now past 8000hrs and the replacements are only about 50% worn with no sign of loss of structural integrity. I would always stick to high volume tyres now rather than the low profile type.

While ballast and pressure are important, especially in the field, another important factor on the road is the guy behind the steering wheel.

 

[Niteforce]

Got a set on a 6499 with just over 4000hrs on at about 25% worn . Max 15 psi down to 7psi for rolling. Not much road work but their not intended for roads are they !!!

What pressure would you run these at for cultivating and drilling ? And also for road work / trailer work etc ?

Find the static load radius for the tyre ,and use that as a guide ,
but remember more tyres knackered from under inflation than over

Ignoring travel speed and load the softer the better for reducing wear

We had Michelin for years, but last set we had were almost gone in 3.5k hrs.
Mich rep said partially down to not enough ballast on front on the road (he recommended min 2t on each tyre) but also use of non carcinogenic rubber now was reducing tyre life.
Had trelleborgs on the replacement tractor and are wearing loads better (prob 50% left, 4k hrs) but not as good at spreading the load at lower pressures in the field as the Michelin imo

Under-inflated trailer tyres are common on the roads around here (Ross, Herefs). These rigs yaw as the loaded trailer sways from side to side. It sometimes looks as if it may wobble in to oncoming traffic or even tip on it's side. If it were mine I'd add a few lbs pressure, save the sidewalls and accept some extra damage in the field. And if the boss might well thinking of following just to see how stable the rig is.

have 710 trelleborgs on fendt 716 that had done the same amount of work (3000hrs)..................i would say they are at 70%....................is the tyre performance in the field better with the michelins? not that i could really notice.

As I have found out these tyres are as soft as butter , designed for ploughing , pity somebody didn’t tell me that before I bought the tractor with them on it , they are the last set of Michelin’s that I will ever let inside the gate . Too dear and too soft , not fit for our mixed work load . Here are the front tyres at 2300 hrs

Grip wise, probably not.
I only found when rolling after drilling the trelleborg left a bit more of a footprint than the Michelin at same pressure.
Nothing to get particularly excited about though.

At the end of the day a tyre that’s good in the field but can’t handle the road work required to get to the next job isn’t suited to a lot of people’s business/system.

however if you are all on farm then it’s a different story.

michelin aren’t a favourite of mine.

I have a set of Michelin machbib 600/65/28 went exactly the same. Only rubbish in my opinion

Funny how different people get on with different tyres. I had trelleborgs on my Fendt. Rear tyres did 4000 hrs amd the other 5000. Still had 60% tread on them but sidewall knackered. Always run at or above recommended pressure. Trelleborgs argument with me was that I had staked them. Load of rubbish.
Michelin on new one one being pdi at the moment so shall see how they do
