MODERATOR could you move this to the toy hauler forum?

The LT E at 80 psi has much less carcass flex trhan the softer sidewall 65 psi D tire.
I see the 15" ST225/75 -15 has a 8.8" over all width vs 9" over all width for the LT225/75-16" which = around .10 wider on each side. I doubt you will have any issue with tire rub especially with the stiffer LT E carcass.

The LT225/75-16 E shows a 29.4" dia vs the ST225/75-15 D or E at 28.3" dia.

I have 5200 lb tandem axles with std leaf spring suspension on my 5er and 16" LT215/85 E tires. I have 2 3/4" clearance at the top. No rub issues.

My tire dealer will mount different sizes of tires on my trailers if need to get proper clearance. Your area tire dealer may also help you in that area as you are buying 6 tires from him. I still use the OEM 15" ST as a spare and has never on the ground.

I too would be concerned if I had Tow Master ST tires on a heavy unit.
You can go to the tire manf. websites and find the tire width, and hight to see if you have enough clearance for a different size tire.

And you will have to buy 6 new rims if you change from 15 to 16 inch tires.

I replaced Tow Masters with Maxxis, 4 years ago, and I am totally happy with them. I don't know how many miles I have put on them, but it includes three coast to coast trips. They are pretty good tires within their weight range.
