Duravis R250 or M895?
Hi Team, Getting ready to replace the tires on my 5th wheel. Looking at both of these tires. They are both fully steel encased. Both seem like Great (and very similar) tires. Do you all see any...

I tend to agree with you that the 2" is not a significant contributor to the sway I'm experiencing on my maiden (1,200 mile) voyage with the new wheels and tires. I've checked bearing pre load, hangers, frame, king pin and associated structure and all check out fine. I've towed this same rig for 10 years now and even to the same destination/roads as this last trip, where I've experienced the sway problem.
One of the areas I want to investigate further, under the premise that the sidewalls are less stiff than a ST Load E, 10 ply tire, is weight distribution. My axles are almost maxed out. They are 4,400 lb axles and on the scales, I am at 8,300 on the 5ver axles (same as its been over the last 10 years). I am wondering if those who are reporting great success with the Duravis R250 have more margin than I do and therefore, don't stress the sidewall strength as much (?). Pure speculative thinking at this point.

The Bridgestone R series tire has been through several updates a premium commercial truck steering and trailer tire with a closed outside rib, rim protection bead and more square tread to sidewall profile due to a stiffer sidewall. I cannot without towing your trailer see why you would have more squirm in the tires but it does not do it on mine. 2" higher in a trailer despite rumors here does not create a detrimental high center of gravity causing sway 12" maybe. The majority of your trailer weight is no higher than 5' off the ground with the exception of the structure itself and is deceiving by looking at the profile from the front. Like Me Again mine rides like it is on rails and my truck is air ride so until the bag on the outward side of the curve is filled to match the difference it leans. Partially filled water and sewage tanks will cause weight to transfer to the outside in a curve. This can also cause minor sway on rutted roads where the narrow light truck front tracking is walking the edges of the ruts and the fluid sloshes. Your trailer should be in the ruts as they fairly close to the track of semi trailers your truck especially SRW are not. Wind is the biggest reason RV's sway due to the extensive surface area along the length of the unit combined with height.
