rear tires

[H. Wayne Smith]

I have a 1951 8n. I know that the manuals say set tire pressure at about 12 psi if no load or maybe bush hog. My tractor was showing a lot of 'squat', ie, it looked low on air. to fix the squat, i put in air until the tire was looking more full. the right tire showed over 20 psi and the left showed about 15 psi. the tires are old and have been on the tractor for a long time. how long i do not know, but at least 12 years.
two questions:
1. car tires have a DOT code that shows when the tire was made in week/year format. Do 8n rear tires have a similar feature. if so, where is it and how do i identify it?
2. i do not know if the tire has tubes. I do not think so. how do i correct the 'squat' problem(the tire looks to have a low pressure. when i try to fill it, the pressure is too high)?.

2 questions back at you:
Are the tires the same size/brand?
Are the 2 rims the same width?
Just wondering!

Easy to tell if there is a tube, just look at valve stem. And very likely
tire is not intended to be tubeless. And I have never seen a date on car
tires.

Go to your favorite search engine and type tire date codes or something similar. There are many sites that can help you.

the tires are the same size and brand and the rims are the same width

i am sure that the tires are tubeless.
the date that the automobile tires are made is encoded in the dot code. for example, i just bought a set of tires for my toyota.
on the side of the tire is this code:1PLOF3C1R1523, the 1523 is the date that tire was made. the 15 is the week of the year and the 23 is the year

thank you for all of your comments so far. However, I still do not know what to do about the tires seeming to be low on air but the tire pressure is above 12 psi. is this a matter of old tires and the fluid inside the tires or tires just being old. I have trouble keeping my own pressure up to par and i know that is an age thing! the tires do have a little dry rot as tires this old would have.

Not sure but my 12.4-28" tires also are at around 20 psi.

I never put a guage on a rear tractor tire with fluid, just go by how they
stand up. Have never heard of a tubeless in a bias ply tire, only radial and
have not heard they make a radial in the size for the small Fords.

The two tieres I bought from Tucker tire last are tubeless. If I had 12 or 15 lbs of pressure I would not worry about what they looked like. Sometimes we can see a problem where there is none.

Tubeless bias ply tires for automotive applications used to be common. I remember changing enough of them in my dad's shop.

... the end of the era for tube type passenger car tires came in 1955, as most new cars rolled off the showroom floor with tubeless bias ply tires.

For tractors? This [b:501527e4e6]Firestone brochure[/b:501527e4e6] lists a bunch. Just not any that will work well on an N.

I've even seen tubeless bias ply tractor fronts in various places. Again, just not any that fit an N.

Late breaking news. I found a pair of 4.00x19 tubeless bias ply tires on ebay [b:501527e4e6]SET OF TWO New 4.00-19 Tri-Rib 3 Rib Front Tractor Tires Tubeless 6 Ply Rated[/b:501527e4e6].
