Tire pressure

mn1500 · Jul 29, 2008

Does anyone know what the proper tire pressure is for a 5 X 15 4 ply 3 rib ag tire, these are on the front of my Ford 1700 tractor with front loader and rear box.

Since it has a loader, I would fill the tires to the maximum pressure listed on the tire sidewall.

That's a compact tractor. Those tires sound similar to what's on my Cockshutt, I put anywhere from 8 to 12psi in the back tires (as long as it's the same on both sides) and about 20-24psi in the fronts. They can probably take a lot more but the front end looks kinda light for a loader IMHO. So a lesser tire pressure gives a softer ride for less stress on the front spindles.

Tractors with loader need more air inb them then ones with out a loader. I bet if you look on the tires it will give you a max PSI for the tires I my self would run them at of just below what max is. My self on my loader tractors I run over size fronts and or like my 841 ford I run LT truck tires up front and keep them up at max psi but I also lift 2000-2500lbs hay bales with it

Thanks everyone but there is not max tire pressure on the sidewalls, that is why I asked the question. A better question is "what is the rule of thumb for a 5 X 15 or for a 4 ply tire? does it matter if it has a loader or not? any help would be great.

I think you'll be safe at 28 psi but if loading the front end heavy you may want to up that a few. David.......

Pump until they look reasonably hard with a bit of weight in the loader. I'd tend to think that 35 psi would be a starting point...

I also run a newer Ford with a loader. The owner's manual says 28 in the front. But in my expeience 32 works much better, especially with the loader. This gives much less tire flex when the bucket is full of dirt or whatever.

They used to recomend a tire pressure on front of a John Deere at 28# without loader but in working ground with that low a preasure then it pushes dirt between the rim and sidewall. always ran at 40# psi on 4 ply and that was general work without a loader. They will easily stand the 40# and the loader weight will not flatten them as bad and that is where tire trouble would come from with dirt getting in the rim around the tire. Me I would put in 45#

Thanks guys, I am running 40, the tire looks a little low, someone told me 44 is the max for a 4 ply tire. I was just trying to get someone to confirm that number.

May as well go to the local New Holland dealer and order an owners manual so you have one for next time.

I had the fronts on my loader tractor filled with that solid foam. Haven't had to check the pressure since. They are unbelievably heavy but served me well the last 10 years or so.
