In 2015 the Trailer King tires were standard. Was able to get the Goodyear G rated tires added reeally just before or dyring manufacturing. Hughly highly recommend the tire upgrade. You wont regret the addl cost.
Yep Trailer Kings and most all of the other brands of big 5er's out there come standard with ST E rated tires whether they are Trailer Kings,Westlakes,Marathons, etc.. Go with a G rated 14 ply LT tire Most MFG's have the option to go with the G rated Goodyear G614's on their Big 5er's and also there are other options on the Market for G rated 14 ply tires besides Goodyear GY 614's that are not as pricey
