New tires
So I saw another tire failure on the highway today, that has been 3 or 4 in the last year , this one was in the middle of the 401 at the express lanes exit to collectors going to the Neilson/ Mornings...

Your Keystone Cougar 28 SGS shows to have a ST225/75-15 D load range at 65 psi which is a 8 ply rated tire.
The Carlisle ST225/75-15 E is a 10 rated tire at 80 psi.
Both tires have a two ply carcass with 4 plies under the tread = 6 actual plies.....however the E tire has a heavier/thicker two ply carcass than the D tire.
Carlisle has a terrible rep with trailer haulers of all types and has been #1 in tire complaints of all the ST tires.
The new Carlisle RH has lost that rounded tread/sidewall profile and is a much better looking tire for trailer service. Keep them pumped to the max for a cooler operating tire and to satisfy Carlisle new tire warranty.
This from Carlisle;
Time and the elements weaken a trailer tire.
– 3 to 5 years is the average life expectancy of a trailer tire,regardless of mileage.
– It is estimated that in approximately three years, roughly one-third of a tire's strength is gone
– After three years, depending upon storage and conditions of usage, consider replacing trailer tires even if they have tread depth remaining.
– After five years, trailer tires should be replaced in all cases.
I stand corrected I thought they were 6 ply. Thanks for the input
