Tire pressure...

Navajo350 · Sep 17, 2015

On my 12.4 36s, should I inflate them to their make to prevent rim slippage and sidewall deformation? (25psi)

I also posted another question in my "Plow Setup" post.

Thanks
Robert

Yes. Inflate to MFGers specs.If not listed on sidewall,call local farm tire dealer.A 12.4x38 tire should have APPROX 16 to 20
psi.Too soft can cause sidewall to wrinkle,leading to tire failure due to cord separation.That happened to me last year. the
18.4x38 tires on my 1256(plowing with 4x16 rollover in HARD pulling 3rd gearTA back!) were low.But not low enough to notice. the sidewalls were separated,chaffed tubes.I was forced to
replace 75% tires at a cost of $1000 each!ALWAYS run at MFGers specs.Buy a gauge('wet' gauge if fluid filled) and ckeck em from
time to time.

Yes,25 psi is fine(sorry didnt fully read the text.)

IMHO 16-18 psi is plenty on a biased ply rear tractor tire,25 psi is extreme!!!! If you look at the outside edge of cleats on a correctly aired up rear tire the outside edge of cleat should be touching soil or road. My previous statement is true unless one has an excessive load on 3 pt hitch then more air pressure will be required.

Yes,25 is extreme.But that is what my tire guy(local 'COOP') recomended to put my 18.4x38 8 ply at.Fluid filled/weighted. So far it has kept
them from wrinkleing during the hardest plowing/pulling.Dont need that much for 'normal' work. Your smaller tractor really wont
need that much.Again,I say MFGers recomendations

Notice as rear load increases so do inflation pressures.

As an old tire man I need more info to help you. What kind of tractor do you have? How are you going to be using it, what type of soil do you have?
