Thanks for the input. Ever since getting my Rubicon with the factory load range E MTRs vs the load range B tire my previous TJ had, I've been sold on the strength of a 3 ply sidewall. Although I hate load range E, I always felt I could drive over anything with my MTRs or my current STTs. Reading your blog is enlightening. Maybe I shouldn't have so much confidence in my tires. Your Toyos are highly regarded as one of the toughest tires available. If they can get a hole, anything can. I was actually a little surprised at how high up on the sidewall the leak was. It looks like it is almost up to the tread. Not what I would think of as a weak part of the tires.
With that in mind maybe it doesn't make much difference in a 2ply vs 3 ply. I'm sure a 3 ply will be tougher, but either way I better be a little more cautious of where my tires are. It would seem a two ply generating less heat could be run at a lower pressure on the highway and not damage the tire. This could be an advantage for a light vehicle like my LJ.
Thanks for your input. I won't rule out the xtreme country due to the 2 ply constuction.
Yep, the Toyos are rugged, high-quality and a round tire, and for many applications having a 3-ply sidewall seems a good idea. But they are all just rubber balloons and can be popped, some more easily than others...sometimes it's the driver, the terrain, or just bad luck.
Heh, a couple of years ago I had some sharp shale slice through the 3-ply sidewall of a nearly new BFG KM2 like a knife, the cut was at least 3" long. As above, any tire can get holes.
Exactly, all can be punctured, and some sharp rocks cut tires easily.
I sent an email to ******** Cepek asking about the Specs on the 255/85R16 Extreme Country. Their reply was:
Thats all they said. I can only assume the 255 must have more rubber than the 285 to make it heavier. I like the more aggresive design of the DC tire but I'm not sure I would choose this tire over the ST MAXX. The aggressive tread is the only advantage it has. The Maxx is lighter and 3 ply side wall.
EDIT: Does it surprise anyone else that the original ST is still offered in this size? Its actually still a tempting tire. Its taller, and lighter than the new STMAXX. But it is pretty narrow and a bit dated. I'm still hoping to see the new STT Pro in this size.
It doesn't surprise me they are still making the original S/T, it's easier to continue making something than design new. I really like the original Discoverer S/T tread design, but you should really study some of the older S/T tire threads here. The S/T [not MAXX] in 255/85R16 is a very narrow tire, the tread tapers inward making the 2-ply [and quite thin and flexible] sidewalls rather exposed. Unless Cooper has changed the design [doubtful] this 255/85 tire was/is only a 4-ply thread...few heavy-duty LT tires that enthusiasts like and run are less than 5-ply treads.
That said, I never punctured one and others seemed to get good service from them. There are fewer size choices in the S/T, and I do wonder how long Cooper will continue making the old S/T, I love the 4-rib design and void ratio.
