ST Tire "Plies" Question and a PSI Question
(BTW I am aware of the various "issues" concerning Carlisles, Marathons, and ST vs LT, having read many tire threads here over the years. Moving right along then-- :) My 2002 built OEM Goodyear Ma...

Totally agree. Standard practice in aviation is if one tire fails, the other tire on the same axle is also changed.
Axles on aircraft are short, stubby things if they have an axle at all. (Could be just a bearing spindle on each side of the framework, I don't know.) Anyway, I can see a failed aircraft tire significantly increasing the load on the opposite tire. This would be similar to a flat on a dual increasing the load on it's mate.
Does a tire failure on a trailer significantly impact the loading of the tire on the other end of the axle? I expect most, if not all the load is transferred to the tire that's on the same side. In fact, when that end of the axle drops it might actually unload the tire on the other end a bit.
And most aircraft with multiple tires on a landing gear carry about 10 to 20 times more weight per tire than our RV tires, so, YES, you have to replace the other tires on a bogie when one goes down. FWIW, EACH TIRE on a 747-8I carries 54,833+ lbs on it at its gross takeoff weight of 987,000 lbs. That's the equivalent of 16 E-rated ST tires at each position of its 18 tires. :-)
