The light truck (LT-type) tire size 7.00-15LT has an overall diameter when mounted and inflated of approximately 29.4-inches. The other tire size you referenced, 255/70R15, will have an overall diameter of approximately 29-inches. You can refer to the linked article on tire sizing for more on tire sizes and weight capacities. I also linked another helpful article and video on trailer tires that contain much useful information.
In the tire size 7.00-15 we offer two bias ply tire options, parts # AM10414 and # AM10412. We do not offer any tires in the wider 255 size.
