Slow leaks, flats, blowouts, tread separation, I had 'em all at one time or another, on 2 different trailers with 4 different tire manufacturers. Then I switched to Michelins and have not had a problem in 6 years. Run 'em on my truck and trailer. Second set on each vehicle now. For a 3 or 4 year life the cost per tire is $70 or $50 per year. Compare that to the cost of alternative tires and the difference is not very great, particularly when you figure the Michelins are trouble free...or at least have been for me.
FYI...on the trailer...Michelin XPS Rib T/R LT235/85R16E1 120R B.
On the truck...Michelin LTX A/T 2 LT245/75R16E1 120R B.
