Load ratings- I need help!

[95PwrStrk]

I am shopping for new tires. I am upgrading from a 16.5 rim to a 17x9" Raceline Raptor.

Here is my huge problem. I have done TONS of research on the load ratings and have come to this understanding.

Load ratings:

C- 6 ply
D- 8 ply
E- 10 ply sidewalls

My problem is that every tire that I find in a 40" tire (the size I want), every single tire is a C load rating, which, in my research, everyone says that is unacceptable to put on a truck as big as mine (95 Ford F350 Crew cab long bed Diesel)

So what do I do? Are these C rated tires okay because of the bigger tire size? I haven't found an E rated tire yet in a 40" tire size.

If I have to stay at a 38" tire to have an E rated tire I would be okay with that, but I want to go to a 40" tire.

Also it has to be a radial with good reviews regarding tread wear and good ride.

Any recommendations or help?

Do you tow with your truck or is it more street driven with towing say a boat or car trailer on occasion? If it is the latter then you will be fine with the 40" tires in a C rating. If you tow heavy then I don't recommend it as you could overheat the tires due to too much load on them causing them to fail.

I don't tow much at all, and it is mainly street driven. However, I wanted to be able to tow if and when I wanted to.

Also I thought a C rated tire would wear faster than an E rated tire?

Load and compound rating are two different ratings.

Look at the actual weight ratings of the tires you're interested in instead of the C,D,E thing. Sometimes an eight ply tire will have a higher weight rating than a ten ply tire, depending on the materials it's made of.

I wouldn't be concerned with it if you're not towing.

those c rated tires are no were near strong enough for your truck, regardless if you tow or not.
