15' tires

mcarter, did you also replace the spare?  I'm tempted to buy a couple of the Carlisles but am inclined to take my chances on the spare.  It'll only be used to get to a repair shop to fix the tire or until I can buy a replacement if it can't be repaired.

I bought the Carlisle 14" D rated tires from Walmart online.  If I went with the 15", I would have had to figure out the correct TV hitch height, plus buy new rims.  I don't know what I don't know about the 15" but the 14" D 65 pound tires are fantastic.  I purchased the $10 Walmart tire guarantee  so if I have an issue, I can always find a Walmart store.  The next rally I go to, I will see who has the 15" and ask if I can test drive their rig and they can test mine so we can compare.

We are just purchasing a 2011 Rpod 182 . The dealer replaced the tires with new R14 class C tires....we have heard that D is much better and also 15 inch better still. Does anyone know if we can change these tires out for 15D tires? New to camping world!! 

Not all "Class C" tires are the same. It depends on the tire diameter (14", 15", 16"), and the cross section.

On our so-called 15" class C tires, the weight rating stamped into the tire is 2350 lbs. That will accommodate up to a 4700 lb trailer (single axle), which is in the same range as a 14" class D.

So check the weight rating on your tire(s). Take the gross weight of your trailer (3800 lbs in our case), and add 10 or 15 percent. For us that would be ~~ 4370 lbs. Since our class C tires are rated for 4700 lbs, we are probably just fine.

I just replaced my C load range tires with Carlisle D range tires.  I got 14 inch tires because the spare is also 14 inch and I didn't want to have to buy a 3rd rim and tire.  As it turns out the Amazon screwed the order up and sent me 1 rim, then sent me a pair and won't take back the extra.  Now I have 3 new 14" rims.  If I had known they were going to screw up the order, I would have gotten 15" rims and a 3rd tire.
