Tires Tire Pressures

I had my 3520 out yesterday to clean up dead tree limbs and trash since we had such a nice day. It was in the high 50s. When I took it out of the shed I noticed I had a low tire on the front. I got out my small compressor and proceded to air up the tire. I looked all over the tire to find the correct inflation pressure. I had no luck. It has r4s and it has a front loader. I've never seen a tire that didn't have a pressure stamped on the side. Need some help. The tire on the other side showed 30psi so I aired the other one the same. I just wanted to know if this was enough pressure to run with the loader on. Also the tires showed some dry rot cracks on the sidewall. The tractor is a 2006 with 223hrs. I was wondering if anyone has experienced the same thing. Thanks for info.

That's odd, the online 3520's manual says "see specifications" for tire pressure but this info is not included in the specs. I had no problem finding correct pressure for my 4720 but JD appears to have forgotten to provide it for the 3520.

If it's any indication front tire pressure specs on my machine have a very wide range, something like "between 25psi and 45psi" for the type of tire I use. Obviously the wide gap indicates pressure should be adapted to load.

Looks like small R4s' is 12-45psi.

Thanks for the information. I was sure the tire pressure would be stamped on the sidewall. I didn't think to check my manual. Lots of good information in there that I had forgotten about. It's still good to have this site to keep me on my toes. Thanks

It's dark and cold outside tonight so I can't be sure, but I had a low front one the other week and the only thing stamped on mine was not to exceed 32 or 35 psi when seating the beads. So I just keep mine at 30. Any less and they squat pretty bad when the bucket is full of dirt/rock.
