Duravis R250 or M895?

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.
