ok, guess I dont know much about tires, but I thought the ply was the number of layers or steel belts in the tire that prevent punctures...

 

I just dont want to keep spending $12 a flat every week the next 12 months like I have this time. The 4 ply cooper St was no better than any other tire I have seen, they get flats all the tiem too and they are a AT style truck tire.

 

That is how Bias ply tires were rated back in the 60's.
Radial tires use Load index. Manufacturers are beginning to steer away from the previous ply ratings and go into load ratings like C,D &E.

Go for the Load E tires then. Can't hurt you more than you have already by running the C load tires...lol
I suppose you could say the LTZ is a D load tire because it's XL of a C load.
I checked the Cooper ST's and those were all right around 118-124 load range. It should say it right on your tire. Like 119 or whatever it is. Check that number and then just go up from there. Make sure your not going backwards. (doubtful)

 

ok, good to know. I was taught old school I guess. Thanks again.

 

just ordered my cooper LTZ will let you know when I get them what I think!

 

another thing I did not mention is I do cut, and haul wood starting within a month or so. That is just another reason I like a heavy duty tire. I have heavy duty springs in the bed, and I want tires that will hold up all the weight, and still not let a rock stick through it.

 

well a 1500 isn't made to be a rack truck and haul a full load of wood, especially green wood which weighs more than 3,000lb per cord. Even at 1/2 that your over weight.

With that said, i do wood all the time. i have airbags in the back and my tires don't even buldge in the tiniest bit when I fill up with wood to the bed height which is just under 1/2cord.
Just because the tires can handle the weight doesn't mean your axles or suspension can.

 

All right, I'm going to get a set of these tonight with 60% tread on them for an awesome deal. I'll be getting them mounted on my procomp rims tomorrow hopefully. I'll be sure to post pics and results. Just can't stand the 31" toyos anymore.

 

I know, I overload it, but cut all my wood in my back 40, so I just creep along and have never had any problems other that the darn flats I get all thetime. When it is loaded up like that I have even had weeds poak through the tires. I may end up getting a 2500 diesel this winter anyway. I dont like their price, but they are hard working trucks. Thanks

 

I would drop down to a 17 rim, more options and cheaper price for a 17 in 10 ply tire.

Tow ratiing and milage will be better when running a 10 ply tire, a 20 in 10 ply tire is a lot of whieght.

I have the nitto dura garppler, best tires I have owned to date, far better off road than the BFG R/T T/A oem tires that came with my truck.

Even 10 ply tires get flats and a 10 ply tire is going to take away the passenger car ride of a truck and give you back a better truck.
