I keep looking in to them but some of the prices I got made me fall over thought I’d found a 2nd hand system last year but then the lad decided to keep it Germany had them on there version of the small grant scheme have you got any info or prices on them from MichelinHad a very informative day with Michelin Tyres this week and there was much discussion about on tractor Tyre inflation systems.
Are they becoming more common?
Would you run them on your machines?
Do you alter the pressures as the weight decreases during spraying or just re- inflate to go back on the road?We have this system on one of our Unimogs. It has a demount sprayer on its back. It is a factory fitted option, front and rear tyre pressures are independently altered by in Cab controls. The difference when travelling in field is unbelievable even on its 24" tyres. You can visibly see the difference in the tyre marks on the ground.
Might be worth a chat with the guys at Tractair if you haven’t already.Funnily enough, I’ve just got home from a local engineers, we’ve been having a look at adapting the system that is on my Zetros. It was supposed to come from Germany all working but it doesn’t and nobody seems to have any knowledge of the system. Teleflow in France are helpful but all they can say is that I have to remove the entire system from the truck and send it to them. I can assure you that is a big job and may disable the machine for who knows how long?
Therefore, today we’ve been having a look to see if we can adapt it to a manual system from the electronic digital system. We’re lucky in that Mercedes route the air through the axle, which makes things easy, and all the major pipe work is in place also including reservoir tanks.
We will convert the wheel valves so they can let air through both ways (they are very intricate and it took us over an hour just to see how they work) and they will include a small ball valve to switch the system off completely to each wheel, making it very safe on the road.
The pipe work will be routed through two manual regulators mounted externally near the cab door. I’ll turn the ball valves when I get off road and then set the regulators to the pressure I need for the job.
By the time I’ve got my first load on the pressure will be correct for spreading. Once finished, I’ll adjust to the road pressure and by the time I’ve got the trailer hooked up it’ll be right and I can then turn the individual wheel ball valves off, making each wheel independent and safe.
I’m hoping to do it for hundreds rather than thousands.
JD are offering it on the 8r and will be filtered down to the 7 and 6 ranges within the next 18-24 months so I was told. MF are trialing a system tooIt seems that Fendt are the only manufacturer to offer the system as a factory fit option, everyone else is retro fit, best option seems to be the CITS (Central Tyre Inflation System) supplied from Tractair.
These systems were on the New Hollands that were on the the event and I've seen the same on a New John Deere that was dealer fitted from new.
Not much to see tbh, there’s 2 pipes, one for inflation the other to deflate, going into one way valves then into the tractor hub. It’s a very neat system and preferable to having the system that hangs on The outside of your mudguardsCan you take a picture of the valve on the wheel
I was hoping there was a make and a part number on the valve to make my own systemNot much to see tbh, there’s 2 pipes, one for inflation the other to deflate, going into one way valves then into the tractor hub.

Shocking firm to do business with,they simply don’t deserve any business whatsoever.I did a few weeks ago, can’t remember who. They said someone would call back, heard nothing I’m afraid.
