Duravis R250 or M895?

I was typing my reply to Mark before I read your suggestion below. I'm running 80 psi now but will experiment with a lower pressure for kicks. I also tow a 21' boat behind my trailer. Same set up for the last 10 years and I hit the scales every year for confirmation that my wife didn't pack too much. My weights are always within 300 lbs of each other.

Since I've added 2"x2"x1/8" square tube cross members to the three spring hangers and reinforced the hangers (doubled their thickness), and reinforced the hangers to frame connections, I am confident that frame or hanger flex is not my problem.

Okay back to the OP's question...

I don't know unless the axles and suspension are flexing more but I can't see the tires doing. My trailer has 6k axles and I am usually pretty consistent at 11600/11800 which puts me on the upper limit as well as the tires at 3042 lbs per tire. What I can tell you is the 1st trip with this pig was bringing it home on the stock GY Marathons it towed like a drunken rock. I was talking to the tire guy I dealt with for years on my class 8 trucks and suggested the R250 as I used to run a similar tire on the steering and trailers. Now I can tell you the trailer tows better behind my dually better than it ever did behind the pickup. It may be the air pressure you have them set at but it sounds like you are a lot lighter than a lot of us. Truck 10,600 + trailer 14,200 + 4700 boat behind and we are getting right up there but tows good and straight which you can see by watching the 2nd trailer. My suggestion would be adjust tire pressures to see if it makes a difference.
