Gents, I have a 226 Larson (3K dry weight) on a tandem roadrunner trailer with ST205/75 D14 tires. According to the previous owner these were bought new about 8 months ago and the condition of the tires appears to reflect this. The tires may have 1,000 miles on them with no cracking, bubbles or any other abnormalities.
Before leaving out this weekend I checked pressure and put all tires at 45 psi. The tires do note 50 psi cold. Here comes the good part, after about the first 5 miles (maybe 15 miles of total travel on the return trip) on the interstate doing 60 – 65 mph, the left rear tire suffered a blow out leaving some carnage on the wheel well and taking a side bunk with it. I had a spare so the day wasn’t spent on the side of the road and luckily no other cars where close at the time of the blow out. The rear axle is my braking axle and I checked to see the wheel was overly hot and it was warm, but did not appear to be excessive.
I did a quick search and it appears that many others have not had great success with this brand of tire. Can anyone comment on the quality of these tires? Should I have not put 45 psi of pressure in the braking tires since they do heat up more than the non-braking tires? I’m not sure what the tire load rating is, but I will be checking it tonight to make sure I’m not exceeding it. Thanks ahead for any responses.
