I plan to cut the deck for the tires to poke up through, and cover them with the top skin. Mounted in their usual manner, they barely stick up above the frame. Most of the height is the fenders.

Is this a common problem with 8" boat trailer tires? The manufacturer ratesthis trailer for highway speeds.

Yes. No 8" tires are rated for highway speed. I think some of the 10's and 12's are. But not all. If it has no speed stamp it is 65 mph top speed rating. Which really means 55 sustained or they wont last. Mine blew out after 60 mph runs. I put about 1200 miles on them and had my boat in the garage.

8 inch tires suck.
Realistically they are probably only made to carry a load at 45 to 55mph.
My 4x8 got good tires because I like to pull it at 75mph loaded or unloaded.
Campers are loaded all the time and are exceptionally hard on tires.
Need to stop being cheap and listen to the people who have owned trailers for many years, built trailers, owned campers had blow outs and tread seperations.

“Tow rating” has no meaning. It’s advice. Insurance covers stupidity, and this idea is common (a camping trailer).

Tires are a concern. E-rated is too high as it’s not a good match. A quality brand passenger car tire where more than 15% reserve is re-elected is the path. I wouldn’t want small tires , 14” are what I’d be thinking about.

Torsion axle needs wheel face (lugnut face) just outside trailer wall for best stability. Leaf spring requires the leaf & axle attach point at above (U-haul style) with wheels well outside.

U-Haul style surge brakes (as with boats) not bad either.

“Where” the axles are located is a concern. The farther back, the easier to tow, but trailer tongue weight goes up. A TW range of 10-15% is standard, but shoot for 12% plus.

Somewhere in the WWW universe is/are trailer-building guides which address above. Tongue length another concern. Etc.

As I understand it, the wheel bearings are the limiting factor, with smaller tires spinning them faster. The manufacturer said these axles and wheel combinations are designed to hold up to highway speeds, though 13s wouldn't be a bad idea.

Our local Purviss Bearing Company' counter sales guy told me that improper lubrication and setting the wheel bearing pre-load too tight were the defining issues for bearing failure.
He said that rpm wasn't really an issue as long as you respected the rated load of the axle.
Rolling resistance might be improved with a larger diameter wheel/tire for the same reasons you see passenger tires growing in diameter.
The larger tires can be had as radials as well.Although there's little available literature with respect to trailer tire R-R specifications.

I used 8 inch tires from 2006 to 2008 then again in 2016. The bearings weren't the problem.
People neglecting, not knowing how to service, setup wheel bearings is the problem.
The T84 spindle which typically comes on a 4 on 4 hub will carry 900lb each no problem.
I upgraded to 1-1/16 inner and outer bearing hubs rated for 1,250lb, I don't remember the industry standard code for those spindles.
The T84 setup uses a 1-1/16 inner bearing and smaller outter bearing.
