from newbies to rvin. we will need to purchase new tires for our tow vehicle. currently having 275-60-20 on dodge ram 1500 4x4. towing jayce eagle 6800lb dry. local tire dealer says staying with original load tire...114 is ok. what are the thoughts of this and what about going to a slightly lower profile tire...55 series but the load capacity rises to 117 or 119.
You will most likely get more wear ( and safety ) by stepping up to a 119 rating.
My Duramax came with factory 245/75R16 Load Range E.
I upgraded to a 265/75R16 E Michelin on 8" wide Weld wheels. They last about 60,000 miles that way so you get your tire money back and enjoy a safer tire in the process.
OEM tires are required by law to be able to handle your trucks full GVWR. Size isn't the real issue here but running truck tires would be an improvement over P rated passenger tires due to increased stability.

I would go for a light LT tire. I like Tirerack for their tire information including weight. LT tires weight more than P rated tires, sometimes as much as 20 pounds. So the increase in stability often comes at a cost of performance.
There are no LT tires in that stock size. The XL load P rated tires in that size are not worth buying IMO. This new Conti looks great for a P-rated tire.
I see from another thread you have a new TT as well. Have you towed with it yet? I would evaluate how the truck does without current equipment before making large changes. 6800 pounds dry is a lot of any half ton, especially if you have a family and a bed full of stuff.You may find yourself wanting a more capable tow vehicle anyway.
