Only two disadvantages that I can see, maybe.

1. Tires are more $. $114 vs $142 for Goodyear Marathons. $130 vs 168 for maxxis

2. Bounce and scrubbing. If I run at 80psi. The tire is underweighted by 1k lbs and if I run at 65 psi then the tires are closer to the proper inflation for the weight but will be soft and maybe be under more stress when turning. With the issue on Lippert frames and cracking, maybe this is a bigger issue.

Other than that I can't think of anything.

Shocks?

With the shocks I added to the trailer, I don't have a problem with the way the trailer rides.
Maybe adding shock would damper the ride? Hoe did you do that?

I just noticed the different size between the two tires, not just load range.

The stock 225/75/15 works out to be 28.3 inchs tall
the actual 235/80/16 is 30.8 inches tall,

So your trailer is sitting 2.5 inches higher than intended and you have 1.75 inches less clearance from the top of your tire to the floor of the trailer than intended.

Without seeing just how those fit, I would be worried about tire scrubbing. plus, I would prefer my trailer to sit as low as possible within reason.

another good point and apparently FR is not worried about it... Probably 3.5 % more fuel with a higher trailer. The 275 is "only 11' 11" high" which is pretty high. I did notice that my unit does sit up pretty high and has lots of ground clearance..

Hmmmm.

Just looking at the brand (I like their trailer tires) they don't list a shorter 16 inch tire, but you can get a load range E tire in your original tire size.

Once you go to 16 inch tires you don't have many options in size.

If it were me, I think I would step back to the 15's just to have my trailer sit lower.

Not to nitpick, but a 2.5" taller tire would only raise the trailer 1.25". That would a minimal amount to hastle very much with- imhop.

Look at my albums, I made special mounts and used PT Cruiser shocks. I have dwgs for a simplier install if interested.

What hassle? Just have the dealer change the tires, it's free and I have to get back their either to change the tires or the sticker.

At the next tire change I'd be looking at about $160 a set less. And many on this forum would and have thought that a BIG DEAL. To pay an additional $40 a tire for no good reason.

Just saying.

I guess one persons misfortune would be someone elses blessing!
I wish I had your "problem" in this area, but I'm not that lucky
