What Ply?

Hello everyone,

I'll come right out and admit I know very little about tires hence why I'm here, tried educating myself online and just end up (pardon the pun) spinning tires.

I'm looking for some tough tires I can take on the logging roads of northern Maine, the roads up there are crushed shale, basically razor blades for tires so I was advised that 8 ply tires are good, 10 is better. I see the D and E ratings mean 8 and 10 ply but have trouble finding it on the tire itself, is it always on there someplace and I'm looking in the wrong place?

Attached is a photo of a brand new tire I was given, the rim won't fit my XJ but I plan on using the tire if it suits my needs, are these Chaparrals thicker ply? My research online shows them as a 10 ply but I'm not sure if these match what I found.

Any help is greatly appreciated, thank you!

I believe the sidewall and tread plies should be listed on the sidewall..Being an LT, that tire probably has 2 or 3 sidewall plies.

The load range C, D, & E are 6 ply "rated", 8 ply "rated", and 10 ply "rated", respectively. The "rated" doesn't mean that's how many plies they have, but rather how many bias plies it would have the same load rating as.

Here's a link for sidewall info: http://www.discounttiredirect.com/di...ingSidewall.do

For a XJ a C load rating is sufficient and strong. As the previous post pointed out this is equivalent to an old bias tire rating of 6 ply. They are going to a numeric load rating as well. This is a better indicator of a tires load carrying capacity without a ply rating. A "C" ply tire is a 115 load rating....verify that for yourself. Also be aware that the higher the load number, the higher the price and this can be significant.

For rocky conditions that you are talking about I would definitely go with an MT tire. I run Cooper STT and like them for the rocky roads of AZ, CO, and Utah. I also like Toyo Open Country MT. Look almost identical to my Coopers, but much more massive. I have heard good things about their sidewall strength.

If you want an off road tire that has a strong sidewall get a tire that is designed as an off road tire with strong tire, such as but not limited to the Good MTR.

If you want a tire that can carry allot of weight get a tire (D or E rated) designed to carry allot of weight.

Your Jeep is a lighter weight vehicle so a C rated tire is what you want. You want an off road tire with a strong side wall so get a C rated tire with a strong side wall.

I have a ripped few more E rated tires on my truck. I have never ripped a C rated off road tire designed with a strong side wall on my Jeep and my Jeep has been in places that were far more abusive on the side wall than my truck could even fit.
