Valve Stems on my New Tractor

[EddieWalker]

What is the reason for having the valve stems on a brand new tractor to be on the inside? Tractor is a 2022 Massey Ferguson 4707. Dealer says that it rides best with 15 pounds of air in the tires, which is probably true, but I don't like how they bulge, so I raised them to 25 in the front and 20 in the back. I still have some bulge in the back, but it's minimal.

What drives me crazy is getting the air hose to the valve stems. If I park in just the right positing, I can get to it easily enough, but if I park with the tire in the wrong spot, it's almost impossible to get the hose to it.

What am I missing or not understanding?

You have R1 Radials. Those are meant to run low on pressure, so they provide a lot more traction and aren't as hard. Don't worry about the bulge.

 

[EddieWalker]

That's what my dealer told me. I thought all four tires where going flat!!!!

Regarding the valve stems. When you have rims that can be turned depending on how a person wants-sets the tire width, the valve stems may or may not be on the inside or outside. Just how that is.

Does it really make a difference? In the last 16 years I have needed to put air in my tires 4-5 times at the most.

Get them set how you want them and forget about them for at least a year.

 

[EddieWalker]

I put air in them once and I've only had it a month. It wasn't fun.

Tractor tires can be fliped to make them wider or narrower. How are your set?

if you look at center of hub (where bolts go) there not centered on the wheel. how are yours set?

that being said, you can also simply use floor jack to lift rear end of tractor and rotate tires by hand.

Or until the ambient temperature changes.

Or until the ambient temperature changes.

I don't think that for what Eddie does it will make much difference.

I know that I have operated my tractor with the same amount of air at 100* & at 8*. Just a little softer at 8*.
But then I'm not doing the same tasks at those extremes either.

YMMV.

Maybe you could use paint or something to put a easy to see mark on the tire or rim to indicate where the valve stem is located.
I do not recommend over inflating tires.

Really! A brand new tractor and those SOB engineers could not figure out they needed to put a valve stem on both sides of the wheel. How dare they make such a grievous error in judgement. Fire them all.

Call the dealer up and demand that the prep man come out and give you the proper amount of air. Damn the operator's manual all to he)). They should have anticipated what you wanted.

Looking at pictures of 4700 series they appear to have bolt on adjustable rims so should be easy enough to swap wheels side to side and keep similar wheel stance especially if tires are not filled with fluid. Agree with stems to the inside is a real pain in the arse.

See folks, this is why you shouldn't drink and post!

Eddie,
Drop your pressure back down. If I run over 20 in my fronts, it’ll start bouncing wildly at higher speeds when towing weight.
15lb is about right. I run ~18.
Valve stems facing inward might offer you a little more protection working in brush.

I am not sure but I have backed into a thicket to clear land. When pulling out a ripped a stem. I was down for a few hours. I can understand how the valve stem on the inside would give more protection.

 

[EddieWalker]

I guess that must be the reason. I would prefer them on the outside, but I don't want to take the time to pull the tires off of the rims, swap them from side to side, and bolt them back together again. I'm mowing open areas, so there isn't a chance of damaging the valve stems. My batwing makes sure of that. It's just odd to me that they are on the inside, and if I park in the wrong spot, so difficult to get to.

I'll bet tires were originally mounted backwards on the wheels, and to have the correct tread orientation they just flipped the whole wheel, rather than do it right.
This image shows a correct right rear wheel. Note valve stem.

You can also make or purchase valve stem protectors.

They are on the inside to keep them from getting knocked off..somewhat protected

Nope. Just as likely.

 

[Bobrown14]

They likely flipped the tires for a wider stance. On hills prolly good flatish land not needed. I have hills and run a rotary mower but I need a narrow stance for tilling rows for our very large garden. overall rear tire width makes a difference when tilling rows. I prefer a narrow stance to wider.

Same with pushing snow - tractor width needs to be less than the width of the pusher.

See if you can determine the tire type. Most of my tractors have radials, but some are bias. On mine, the radials say 25 is max. I assume max only if carrying maximum load, otherwise I back off the pressure. All radials will squat - its just their design. What I do is put them on flat surface, like concrete and asphalt and check the bars. if the outside edges of the bars are not in full contact, I lower pressure. On one of the tractors, I run 8.0 to 8.5 psi on the fat rears, which gives me great traction, improved flotation over soft ground, and a smoother ride. The narrow fronts are bias, has an FEL and they need 40 psi. With a bigger tractor with an often-used FEL that might pick up trees, the fronts are 25, the max, while the rears are around 20. FWIW, I use a digital gauge to ensure accuracy, otherwise one side may ride higher than the other due to pressure differences that are not visible.
