These look like " traction grip " tires to me & you can get the tubes & flaps with them.....
I Installed a pair of these on my 1 ton with the original 17" 3 piece rims & they work nicely.

They only have a speed rating up to 112 mph.
My 46 1 ton dually has 7x18,I wonder why they messed around with such small tire size increments in the years.
19.5s are in or has been in a phase out period and are getting harder to find.
