Loaded Tires

[Mcrafty1]

I have loaded tires on my JD 4020, they came to me that way. My question si do loaded tires make them appear underinflated? because mine do, they state 18 lbs. on the sidewall which they have but appear half flat to me? is this common with most?

Are they radials. or Bias tires? Radials don't look the same as bias tires with the same pressure.

How long have you had this tractor? What size tires?

i run radials on my tractors and they do look different then bias ply tires. but what i have been doing is any tractor i have that had loaded tires and have rim problems i have bought new rims and tires and use axle weights. changing rear tires in itself is work but the slop with loading tires i am over. just what i do.

I know I'm stating the obvious, but are you checking the tire pressure with the tire turned so the valve stem is at the top?

Have you tried a different gauge? FWIW, they make special gauges for ballasted tractor tires; they're spring-loaded so any liquid in the gauge gets ejected.

Do you ever run into Mike Simon, of the Dirt Perfect operation in Derby?

the name does not ring a bell, there was a Simon or two i would run into with a seed company when i was buy senginta seed . (spelling on seed name)

About 2 years, the tires are 16.5 x38's if memory serves me...I'll check that size later this morning.

I have not tired a different gauge and the location of the valve stem I can't say.

They are radials.

Not to steal the thread but quick question on loaded tires.
I can get two used mounted 16.9 -30 tires mounted on rims w calcium with 95% tread for cheap.
If a man were to dismount the tires and clean them up and install on new rims dry would they be ok? Is there something that calcium does to the tire that you would want to avoid? Have seen some pretty bad tire beads rusted stuck on rims. These particular mounted tires have rusted rims.

Clean the tires up and mount them with tubes.

Edit: To clarify and eliminate confusion, use new tubes. I did not specify that before as info was not given as to whether the tires in question were mounted tubeless or with tubes. If the rims have rusted out having tires with tubes in them the indication is very good the tubes are leaking and would not be reused.

Never Had radials .would like to try them out . I get the gage out all the time on the truck ,(is it down ?)

I have supervised or personally filled many tractor tires both when employed at JD dealership & after beginning custom farming. Rear tire psi stated in operators manual is only a guide line. Different amount of weight the implements attached to 3 pt hitch on each tractor actually dictate psi required in rear tires. I agree radial tires squat more than bias ply tires. Higher pressure in tractor tires create a firmer ride for tractor & operator.

If it's the tractor in the picture, they look like 15.5x38. Depending on what you do with it, 15.5x38 isn't much of a tire for that size/weight tractor. My 4020 had 18.4x34, they were OK. If I had 38 inch rims I'd want 16.9x38. 15.5x38 is such a low profile tire it doesn't hold much fluid, and doesn't ride as well as a larger tire. Dry 15.5x38 worked well on the 2510/2520 for row crop work. We had an AC 6060 with loaded, bias, 15.5x38. They weren't enough traction or weight for that tractor. We found wheels and rims for 18.4x30 tires and installed them loaded. Then we had the traction we needed.

Agreed. Radial tractor tires are made to squat some to increase their footprint length on the ground, Radial tires have something like 20 to 30 percent larger footprint than the same size bias ply tires? Excessive tire pressure will reduce the tire's footprint and increase soil compaction.

Maybe the OP can look up the tire manufacture's website to find their pressure recommendations for the load on those specific tires.

Used 18.4-38 tires are easier to find than narrower sizes.

Many larger mid 1960 tractors were equipped with narrow front end and 15.5-38 rear tires to carry a mounted corn picker through 38 inch rows.

That's for sure. I had to special order Firestone radial 16.9x38's.
I've had the bias 18.4x38's off that tractor here in the barn for probably 15 years. (They were oversize) I just got rid of them last week!

They are 15.5 x 38
