Replacement tires for 1956 Overlander

I have a 1956 Overlander with the original split rims and very old if not original 7.5x15 tube type tires(can't believe they still hold air). I had the trailer flat bedded to its new home and have only moved it off the truck and into the yard.
I have new 15" wheels from VTS but the tires available today do not come close to the almost 30" diameter of the original wheels and tires.
What have other owners of these old trailers used for wheels and tires?
I know running gear upgrades are in the future but right now I want to get the trailer off those 50 year old tires and I want to buy the right tires the first time.
Any help will be appreciated.
Thank You,

Replacement tires for 1956 Overlander

Good to replace the split rims - potentially dangerous and very few places will put tires on them, fix a flat etc.
Here's a tire diameter chart you might enjoy.

The tires on our 75 were 7.00x15s, 27.88 inches in diameter (by DOT numbers one of which could have been original when we got it a couple of months ago). But because there was tire contact with the lead edge of the wheel well, we replaced them with smaller.
Then the discussions will begin about truck vs trailer tires, preferred brands, "upgrading" to 16" wheels, etc.
My Father, a chemical engineer for Gates Rubber product improvement when he retired, was an avid RVer for over 30 years, his towables always had trailer tires and he never had problems.
So I figure if it worked for him ...
Tire life according to current sources is anywhere from 3-10 years depending on who says so, and if the tires are subjected to UV, unweighed and pressure reduced when in storage.

Whats the matter with 700 x 15 again? And then again you can go 225 x 75 x 15.

I was looking at these for a more vintage look on Argosy before installing 16 inch tires and wheels.

We were advised & have been running the Maxxix ST225/75R15 8PR as the closest match to OE bias for our single axle 1960 Avion T20 with no problems & very easy & smooth towing (as well as now running similar Maxxis LT C rated 8 ply tires on our 1988 VW Vanagon Westfalia & very happy with those too - best since the OE Michelins for it).

I was told the Maxxis are much better made than the CW & others' basic tires (many from China made companies), & better than the Goodyear STs too, & I would agree.

ST Radial M8008 | Maxxis Tires USA

You'll want to match or exceed the original bias ply rating, size, etc. with those on their chart, then find a local shop which can order & install them for you on your new rims. Don't use the splitty's!

PS - you can use this tire size calculator to plug in the old size & new size to get the new converted size with all the relevant numbers. Odometer/speedo error won't be an issue for the trailer, just proper fitment in the wheel well.

Good Luck!
