I get the impression the Hartland "all steel" 235/85/16 tire sold by Discount (America's) Tire is a rebranded Gladiator QR35 (part #1942273865, not part #1933273865). Note the pic I took of a Hartland tire at a local Discount Tire today vs. a pic of the QR35 Gladiator from onlinetires.com.
Haven't heard much good or bad about the Hartland brand. As far as I know, the Gladiator QR35 has a good reputation here on rv.net. If it is indeed a rebranded Gladiator QR35 then that bodes well for the Hartland.
The 235/85/16 Hartland (all steel) appears to have a load rating of (129) 4080 lbs. at 110 PSI, a speed rating of (M) 81 MPH, and weighs approx. 60 lbs.
Local Discount Tire was more than willing to match or beat the best online pricing (with shipping), out-the-door, I could find on similar all-steel 235/85/16 trailer tires like the Gladiator QR35 and Sailun S637. Not sure if the salesperson did it mistakenly, but he also offered a road hazard warranty for the Hartlands as part of his quote. Cost slightly more than $100 for 4 tires.
When you factor in the considerable number of Discount (America's) Tire dealers throughout the country (a good thing in the event of a warranty/road hazard issue while on the road), the Hartland tire may warrant a second look for some.
BTW, simpletire.com was offering $40 off a set of 4 S637 Sailun tires today. A set of 4 was approx. $550-$575 shipped. FWIW, the salesperson I spoke to at Simpletire said if I placed an order, he was willing to call the warehouse and confirm the DOT date stamps with me prior to charging my card.
