Hello All, I am considering purchasing a 2021 GD 2400BH for my family and I. We strictly do off grid camping deep in the backcountry and I am always searching for ways to increase ground clearance in any trailers I've ever owned. I assume these 2400BH come equipped with 225/R15 tires that have a overall diameter of 28". Does anyone have any experience running a taller tire of at least 30", preferably 33" tires?

How tall of a tire can I use on GD 2400BH?

Given the 3500 lb axles your probably correct on the 15" tires. I am pretty sure you wont be able to fit the sizes you want. You might get a 16" (80 series), but you need to do some measuring. I have a thread on up-sizing my rigs tires (use the search feature).
To get the lift you will probably need to use lifting blocks, or better yet sub frame the suspension to get the lift your looking for.
Hope this helps

Yoda, what did you end up doing as far as a wheel/tire upgrade? I had upgraded to 16" on my previous trailer to be able to use LT tires, as well as gain height at the truck. Now, running the 15" Endurance tires, and setting level in my GD 273MK, I no longer feel the need to use LT tires. Time will tell if the Endurance tires will hold up.2020 Reflection 273MK

I purchased the blocks from TrailerBlocks.com.
I'd recommend staying with the OEM tie plates. Trailer blocks also sells U-bolts, but I found they were prone to bending when I used them. So I'd recommend finding another source for your U-bolts either on-line or from a good suspension shop.
