Bigger tires to help level?

5th is a 2016 Hideout - truck is a 2014 Ram. Overall, my setup is good with lots of bedrail clearance but the trailer is a couple inches nose high. I'm thinking of losing the crap stock tires and got to wondering if I could go up a size to get the 5th a bit taller. I know it wouldn't be much but I might as well take advantage if possible. Has anyone gone up a size? Any clearance issues or problems fitting on the trailer rims? I suppose there would be an issue with the spare so maybe I'd have to buy 5. This idea is very much just a fleeting thought at this point.

A three inch taller tire will only raise the coach 1 1/2 inches...

By " lots of bed rail clearance " do you mean over 6" ??

I'd be tempted to lower the hitch , before raising the trailer , it's the raising of the center of gravity and increasing the tendency to roll when cornering.
Note: I flipped axles on a 5th wheel, when I changed tow vehicles , gained 5" but lost a lot of stability.
Heavier shocks , springs and tires , and I still didn't get the handling back.
You'd need 4" taller tires to raise the fiver to level and I'm pretty sure that would mess up the handling of your unit.

If you are only "a couple of inches" nose high I wouldn't worry about it. As mentioned, lower the hitch if you have room, but you could create other problems by going with larger tires.

I have about 7.5" of clearance now. Lowering the setting on the 5th wheel "arm" that goes down to the kingpin is also an option. It tows fine and the nose high really isn't an issue. I just figured if I was getting tires anyway it might be a good time to get little more height.

Also, the trailer's rear bumper is super low and drags sometimes. And in all their wisdom, Keystone mounted the jacks almost completely at the back. After ripping one off on a gravel road I re-mounted them further forward. Lowering the front and/or raising with tires would all help.

I was mainly just wondering if any issues come up when going up in tire size - rubbing, won't fit on the rims, etc.

A larger tire , would possibly require a wider rim , a taller tire, on the same diameter rim, will have more sidewall flex.
JMHO: Adjust the hitch / pin box height first , to achieve level or 6" of box clearance , and see how close you get to level , getting a tire size that would lift the trailer about an inch , would be less of an issue with clearance , handling, and rim sizes, that trying to raise it with tires alone.

If you're looking to get new tires anyway and can fit a 16" tire under your 5er then IMO absolutely go with 16". If you really want to take it a step further go to an LT tire. Bridgestone, Michelin and Salium all make high quality ST/LT tires that many use for upgrades over the sometimes crappy ST tires. It's a lot more money for the LT's but they'll save you money if you ever have a blowout from cheaper ST tires.
If you have 6 lug rims then you should be able to run some 16" tires. Most RV 6-5.5-16" rims are 6" wide.
A high quality tire would be something like this;
https://www.tirerack.com/tires/tires.jsp?tireMake=Bridgestone&tireModel=Duravis+R 250&sidewall=Blackwall&partnum=185QR6R250&tab=Spec s

To do a complete swap would run you about $1300.
If you went with 16" ST tires it would be much less.
Goodyear has come out with a new ST tire that hasa 6 year warranty. Carisle HD's are also new and improved.
Either way JMO but moving up to 16" will solve two problems. You'll gain an inch or so in height and you can run a better tire.

Don't think bigger tires will buy you much. I agree with lower the hitch if you have room.

Of course we don't know what your current tires/rims are?

16" Sailuns LR-G are kinda tall, about 31" OD. good value.
Lower the hitch or raise pin box one notch.
Level towing is a good practice for all components.

Be well.

Check the leaf springs are the right size.

You could also add one of the suspension enhancement kits like Timbren Morryde Equaflex Dexter EZ-Flex.........some of these will add lift.

Get rid of the pick up bed and go to one of those aluminum flat beds with lots of tool boxes. You will never regret the upgrade. Ever try to reach something right in the middle of that damn pickup bed? Now you can boondock without worrying about bed clearance. 6 inch is not enough clearance for any real adventurer.
