You're missing the whole point, read all the posts over again.

 

I don't need to read it again, I get where you guys are coming from as far as the load capacity of the tire being the same as a E rated tire, what I don't get is why everyone thinks its ok to put a 6ply C rated tire on. I even highly doubt any reputable shop will do it.. Why did you go with E rated tires on your recap's Brent when you could have got by with C rated like most Toyota Corolla's have?

 

I have expressed my opinion on this matter and I am going to be done with this thread now, ( I got that one from Brent ) Carry on with using a 6ply tire to do a 10ply job...

 

Sorry, you're wrong here. A Corolla doesn't have an LR C tire, those are exclusive to LT-rated tires. Most all passenger cars, as well as light trucks, come with P-metric tires, and there is a difference. They are NOT the sam as, nor are they even close to, an LT-rated load range C tire. In fact an LR C tire doesn't have 6 plies either, just as an E doesn't have 8. It's an equivalency to an old standard from years ago when tires had additional plies to handle more pressure.

Normally I'd post a comprehensive tire load chart that I have on my computer, but I'm traveling at the moment and don't have it handy. All the load range indicates is the maximum pressure the tire can handle, and of course the maximum load is determined from that and the dimensions of the tire. The OP's tires are rated for more than his max GAWR for both axles, which means they are perfectly adequate for the job from a load perspective. They will carry the weight just fine. They are NOT passenger car tires.

 

Thank you guys for all the input I will post pics once I get tires mounted here in a week or so.

 

Well Tom you are wrong , here is the specs from Nitto tires on their ply's
Technical specs are subject to change without notice.

LT tires with a "C" load range have a 6-ply rating. LT tires with a "D" load range have an 8-ply rating.

LT Tires with an "E" load range have a 10-ply rating.

*Indicates Extra Load (XL)

 

Now I am done..

 

Read the link, it's a ply "rating". The tires don't actually have 8 plies. Do you want me to find another source for this? Stand by...

 

Here you go:

SOURCE.

 

Quit dragging me back into this thread Tom. I don't get what the difference is, it says a load range C tire has a 6ply rating and a load range E has a 10ply rating, doesn't that tell us that a load E is stronger than a load C ?

 

Sorry, I really can't help myself. Perhaps I've had too much coffee!

Yes that's true, an LR E is stronger than a C. But it's only an apples-to-apples comparison when you're comparing the same tire size, because the load range is only directly related to the maximum pressure a tire can handle.

For example, a monster truck only has 5-15 PSI in those big meats because it has so much surface area on the ground for that pressure to act upon. Such a tire can't even fall under the LT spec because they are incapable of even holding 30 PSI. But of course a monster truck weighs far more than a Super Duty, and those low pressure tires hold the weight just fine.

An LR E tire in the OP's size doesn't exist because it doesn't need to. That tire in LR C is rated for more weight than most LR E tires are. To put simply, you just don't need 80 PSI in a tire that size to hold 3,400 lbs. Because the tire isn't rated to 80 PSI it's considered load range C, but that doesn't mean it's not as capable as lots of load range E tires.

Can't upload it from my iPad, so here's a link to that table on my Dropbox:

Fair enough, it would still give me the shivers walking by a Super duty and seeing load C tires..

 

Might stay away from lifted superdutys then. When you get to larger tires the e rated tires get scarce. And if what I take from tom is correct the letter ratings corespond to psi rating not weight rating. Ply ratings are insignificant as a manufacture could produce a 15ply load c rated tire or a 3 ply erated tire if they wished

 

exactly .....to op your big beefy new 43s are more than adequate....get them pics up soon man

 

The bottom line is most people don't realize the tire size affects the rating for a given weight of truck.
