Trailer Tire Blowout

[Bushbeater]

My trailer is parked, not used in a couple of months as the boat is on a lift. Noticed yesterday the spare tire had a catastrophic blowout. I last checked inflation back in January before a trip to Taney, and had it at 50#, per specs. I'm guessing the sun caused enough expansion to blow it. But why the spare? BTW the tire was 3 to 4 years old but had never been driven on.

Happens all the time here at my place.  Sometimes during the middle of the night, but usually mid-day when it's hot. Luckily I've never been walking past one when it decided to explode.  Scares the crap out of us everytime one of them blows.  

It's strictly a TRAILER TIRE thing.  I've never seen a car/truck tire do that.

FWIW I run 42# in all of my trailer tires regardless of what it says on the sidewall.   They wear nice and even whether it's my Jon boat, bassboat, or pontoon.   It just looks and feels more appropriate.

Trailer tires are a funny thing.  No matter what the rating on the tire, I always come up with different results.  Put new ones on the little jon and they have about 2k on them, burning thru the tread fast.  Road rated 80+.  Nice set too with steel valve stems.  That little boat should not be eating the tires that fast.

Radials on big boat, 4 years and no sign of wear.

I run 50 in 6 ply and 30 in 4 ply.  Works for me.  Truck trailer, jeep whatever.
