New tires

I feel for the people on the 401. I was up through there a couple of weeks ago. You guys have more than enough traffic to go around.

Stayed at a nice campground just off the 401 out east by Pickering. Glen Rouge Campground, it has just over 100 spots and was nice and quiet. Our friends didn't even know it was there.

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

Ok I will keep looking but Maxxis Canada has the nearest dealer listed at the other side of the country. The newer radial trail "rh" tires dont seem to have bad reviews like the older ones. If anyone has real time use of them I would like to know their opinion

I hope it works out. I have been using Maxxis with excellent results
