A couple of months ago I bought a Cougar xlite 21RGS which has the original tires 225/75R/15D on it (date code 2013). I put it away for the winter but will replace with E rated tires in the spring before we use it again. Talking to Discount Tire they tell me that they don’t even stock the D’s since all they ever do is use the E’s. They recommended the 80 PSI and I would think going form an 8 ply (D) to a 10 ply (E) would be a benefit too. I asked whether the wheels are okay going to E’s and he didn’t think twice about saying it’d work. Is this sound right?
