No, the 4 digit code is week/week/year/year.

HERE is a reference.

Brain fart.. But it does look like a 1 at the end..

Neither front tire has a dot stamp on the outside wall, The number must be on the other side

No worries, Bill.. I'm sure it's 076. The fellas are right that it is probably a small symbol.

If it makes a difference, mine came with 1999 Goodyear's in 'like new' condition. I have 600 miles or so on them since I got it.. Funny thing is, they only had 50psi in them when I drove it home about 160 miles. Didn't know it then. Have 70 psi in now and they are still good. Would I trust them at 60-65mph cross country? No. But they will be fine for 50mph and less than 100 mile trips.. IMHO.

So did I! I typed "month/month/year/year" when I meant "week/week/year/year".

The tire pressure stamp on the tires says 90 psi max, they all had between 65 and 75 psi, So I pumped them all up to 85. I cannot find a tire pressure label anywhere in this camper, so I guess I am guessing at the pressure to put in them.
My brother is /was a long haul trucker and said some of the tires he ran in the day were as old as dirt and sidewalls were cracked and they were
re-grooved and then retreaded and done again and they still ran them, he said to keep the speeds down to 60-65 and check the tire heat from time to time, and don't let them get really hot, he suggested that armor all was my friend

On RV and truck tires the pressure on the sidewall is not the maximum it should ever have, it's the minimum pressure to support the maximum rating of the tire. Same with the tire charts, it's the minimum pressure required to support the weight specified.
To know the correct pressure you need to get it weighed on all four "corners", then go to the manufacturers charts for that tire. Use the highest weight on that axle and use it across all the tires on that axle. Do not run different pressures on the same axle.

Just one more fyi..Check with the manufacturer on the wheels as to what max air they can handle. I have seen 10 ply tires rated for 80-90psi 235/85R16's on 16 " wheels that were rated for 65 psi. Another accident in the making....

I got my new to me rig early this year and felt the same as the OP. Tires looked OK, lots of tread should last a few more seasons. They were cheap MasterCraft with no DOT code. After a couple flats and sitting on the side of the hi way waiting for a service truck I found the money to get them all replaced. Fortunatey they were rear blowouts and not to scary (other than the bang) one did cause damage to wheel well and trim.

If you continue to run with these out of date tires recommend you have a good road service package, spare tire, cell phone or proper tools and jack. And oh yeah, lots of extra time to sit on side of the hi way

I found the Tire label certificate in of all places under the dash and behind a carpet on the sidewall and It states my GVWR is 15,600 and both the front and rear tires are 225/70R19.5F 19.5 x 6 and all the tires should have 70PSI cold, looks like I have put too much air presssure in them,
I was not driving it like that, just moving it around the yard to mow the grass

What does that F stand for?

The F means load range F. The load range replaces the old ply ratings that were used for years.
