From reading this long thread, I get the idea that many folks want to go to a larger size TT tire because they are on the ragged edge between the weight of their loaded TT and the factory supplied ST tires. There is little margin for error. Is this correct?
Now to my situation. I just bought a used HiLo TT. The GVWR is 5,500#. The GAWR is 3,500# each, totaling 7,000#. The ST205/75R15 LRC Goodyear Marathon tires have a weight rating of 1,820# per tire at 50psi, totaling 7,280#.
Given these numbers, I presume "margin of error" isn't something I need to worry about, WRT the axles and tires. Am I correct?
Interesting side note. They are factory supplied tires. The 2 on the left side are USA Marathons built in 4408. The 2 on the right, plus the spare, are Chinese Marathons built in weeks 08,09, & 10 of 2008.
Yes many people are upsizing so they are not running on the ragged edge. It appears that the manufacturer of your HiLo is one of the few that did not cut corners with the tires. Probably why they went belly up.
