I thought I could get away with my 7 year old Marathon tires this year as well. Found out that I couldn't. 2 of the 4 had major bulges and had to be removed on the spot. One blew on a trip, but I can blame that on the shackels braking and not the tire. But, the point is, and everyone on here will tell you, 7 years is too long for a trailer tire.
Where are your 2 bad tires located? The one failed on mine is at the right front side and the diagonally opposing one also showed signs of belt separation. The other 2 still looks good with a bit of tread left.
Everyone here is talking about replacing trailer tires every 7 years. My last set of Marathon still looked good after 19 years when I sold off my last TT as a reclamation project. These Marathon were made in Canada in the '90 though. We didn't travel enough to wear them down
to get new tires. We keep the pressure up on every trip, park at home out of the sun and keep an close eye on them for dry rot or uneven wear pattern.
