I bought four tires, they all have the following stamps: 432001, then they differ with these stamps, P41, or P42 in a stamped depression, and following date codes, 1512, 1712, 3212, 3412. Both tires have Made in USA molded into the sidewall.
I don't see a factory code for P41 or P42? They shipped each tire separately from the same address, they came over the course of a week even though I ordered them all at once. Shipping was free and I was told they, at that time, had 'unlimited quantities available. They were ordered from here in the USA.
All are identical in size, two are mounted on Vintage Firestone rims that came off my 3012 stamped '1969', and the other two are on two unbranded 7" rims dated 4-197.
All four tires measure identical, I filled the one pair today and mounted them on my 3410, they measure only 21.5" filled, and 20.75 on the tractor with weight. Each tire has 5.5 gallons of washer fluid in it. They are inflated to 18 psi. I tried a lower pressure but had trouble keeping them seated on the rim?
The tires I took off were super tough to unseat, but these tires slipped right on. I can push the bead back pretty far if I really try, I had washer fluid bubbling out until I hit 20 psi on all four tires.
I'm sort of wishing I had gone with two more sets of BKT tires, but I got a super deal on these, Less than 1/3 the best normal online price I could find. They came from a mower parts supplier that sells online.
I didn't actually order Carlisle Tru Powers, They were advertised as Power Tracs, which I would have preferred as i still have one new, odd Power Trac here that I don't have match for.
I have BKT tires on my one AC 410 and on my 7116, and Both Dico and Carlisle Tru Powers on my Bolens.
I will try to call or email Carlisle and see what they say. If they are counterfeits they came branded from a major supplier of small engine parts. They were not sold as blems.
I see various ads that list the following specs on these:
Max Load 1115 lbs/22PSI max (Mine are inflated to 22PSI)
22.4" Diameter ( I get 21.5" overall height)
8.2" wide on 7" rim. (I get 7.75 overall width)
Air pressure don't affect standing height much, once they get about 8 psi they hit max diameter unloaded. Adding extra air don't increase size in any direction.
My older Tru Powers are actually on the big side compared to the turfs they replaced several years ago, I was sort of expecting the same thing with these.
