Hello everybody. Im just getting started in rv'ing and have realized that the class A I purchased has almost 10 year old tires on it. I believe one just developed a knot on it. So yes, I need new tires. The size on the tires is LT235/85R16. Then it has 10PR, im assuming thats 10 ply. So my question is how much can I expect to pay and what brands to look for or stay away from. I did a little searching and have seen this size on the internet for around$135-$160 each. Is that about right? Any advice appreciated. Thanks.
