Not sure where this post is going and it's convoluted with 14 and 15 inch opinions. Bottom line is the D rated 14" D rated are an improvement for many reasons over the C rated tires. Load rating, speed rating, price. I felt a significant improvement with going from a 14" C rated to a 14" D rated and am extremely satisfied with the Carlisle's. I believe I don't need a spare that is D rated, unless I was to add into a rotation pattern. If you are using a current 14" C rate, you will see a noticeable difference with a D rate. If your plan is to go larger in wheel diameter then you need to consider a 3 wheel replacement that gains you 1/2 in clearance, pretty costly and I agree that the 15" tire replacement have different specs.

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.

Some valid points and your right it does depend on tire size and how many ply's, ect. that determine load ratings. Some other points to look at when considering increasing your load rating is also what is the speed rating for your tires of the size you use? The higher the load and speed rating the cooler a tire will run which means greater safety and reliability. Though beyond a D load rating on tires in 14" or 15" for our trailers I would consider overkill to say the least. Consider the very top rated tire the Goodyear Endurance tire in ST205/75R14 in a D load range is 2040 lbs. at 65 psi. and is an 8 ply tire with a N speed rating of 87mph. The same tire in a 15 inch size has as load range at 2150 lbs. at 65 psi. with the same ply's and speed rating. I'm considering seriously going with the Carlisle Radial Trail HD ST205/75R14 tire which also a 8 ply tire with a D load range of 2040 at 65 psi. with an M speed rating of 81 mph. for about half the price plus then for the Goodyear Endurance's. The reason why is since we are only pulling two tires that the rubber meets the road I want piece of mind when having to cruise high speed long distance on the interstate. Though I am still debating on swapping out the C range spare tire for a D since its only for emergency use.

Lori. If I had to do it over again, I would have bought used. All the extras cost money. So that factors into the price. If you buy used, then it is worth going to the international forest river rally in august in Goshen Indianna where the manufacturing plant is. It is a long trip from florida, but make it an adventure. Free of charge, they will check out your trailer. Last year they recaulked all my outside seams. I had them add a few upgrades and they only charged me their cost on parts, with free installation.

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.

hurry and replace the c class tires. It is still hard to believe the fantastic difference the d class is to the ride. Don't know if they would give you 15". Don't forget the spare. I am close to the limit in hauling capacity so it made a big difference with me.

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!!

You're fine, a 1/2 inch is what you're talking about. Wise choice in D rated.
