Lost 3 after 3,000 miles on Highway I10(within 500 miles). Lost one side of trailer. Would have lost both sides if not for TST tire monitoring system. TST gave me time in 2 cases to pull over. The second tire exploded. To get back home I had to buy in total 3 replacement tires, not the ones I would have picked... This last week I bought 5 Goodyear G614s, bringing to 14 the number of tires I paid for in less than a year, including the original on my 2013 Cyclone 3010.So I have one with 3500 miles, one with 200 miles and 3 tires of different brands with under 100 miles... The 3 Temps cost me 500 bucks. The G614 RSTs cost me 303/ea at a Good Year dealer in town, plus valves and balancing and sales tax.. so around $1740. The repair to my Trailer will be around 2K. The Goodyears are "G" rated 14 ply, the Max Tow were 10 ply "e" rated. The Goodyears weigh about 25lbs( 60% more) more each and are US made. I would not think of using anything less than "F" rated. The other cost were missed stays/reservations, ruined trip, as we sat in parking lots and the time to get new sets of tires and the 4 weeks till repair. I would not advise anyone to keep these tires on, it will cost you more to keep them in the end and sitting on the side of roads is life threatening and there s also the chance of a fire. Heartland needs to up the price 1K and save us all a couple of thousand in the first 12 months. The rims were fortunately 110PSI, so I could stay with the originals. A warranty is worthless in the middle of nowhere on the side of a freeway, and I only kept the one that exploded. I did not think when the first one went, that the others would all go in short order. Also note the 80 aspect ratio(lighter tires) is rarer than the 85 aspect ratio as with Good Year. I found no other tires but the Good Year rated "G" except one by Power King, thanks but no thanks... Better to pay 20 bucks more for the Good Year.
