Long way to say the same pressure on different model tires is going to result in different experiences. More rubber and deeper tread can contribute to smoother rides. Different sidewalls may need different pressures to tune for ride quality and sidewall stability.
More reasons why RCTIP is misleading and should serve as a starting point to tune from.
this seems key. I found a video comparing an sl variant of the Nitto recon grappler against its light truck variant of the same size…and the tires flex was significantly different at the same pressures…as well as its compliance (damping I assume).
It’s too bad there isn’t a repository of tire deconstructions on YouTube…it would probably get a reasonable amount of views…I’d like to see a cutaway of whatever the extra falken “turn up” ply looks like compared to the 2 ply competition in standard load…as well as how hard it is to tear the material…it SEEMS like they’re trying to market a “tougher” sidewall’d SL tire than the competition for people that want a max durability SL tire but don’t want a light truck tire.
Quotes on the topic I found:
“
I would 100% agree with your initial inclination to opt for our non-LT 265/75R16 WILDPEAK AT3W with Load Index 116, which is in between a Load Range C (112 Load Index, aka 6-ply) and a Load Range D (119 Load Index, aka 8-ply), and far stronger than your OE fitment which was most likely P265/70R16 112.
I also agree the Load Range E version LT265/75R16 (123 Load Index, aka 10-ply) will be too much tire for a Tacoma, sacrificing fuel economy, and comfort as you said. The LRE version is really designed for a 3/4T truck application such as an F-250. You would actually compromise more than just comfort and fuel economy with the Load Range E version, as the contact patch would not be ideal, and could sacrifice wet and/or other traction characteristics. In fact, I always recommend our non-LT version for Tacoma owners, when asked in person or by email, and openly on TacomaWorld.com.
In terms of pure load carrying capability, our 265/75R16 116T WILDPEAK AT3W is superior to competitor offerings in p-metric P265/75R16 Load Index 112, as well as superior to competitor offerings in LT265/75R16 Load Range C Load Index 112.
To answer your question exactly, the construction of our WILDPEAK AT3W is as follows:
Sidewall: 2 -PLY POLYESTER WITH HIGH PLY TURN‐UPS
Tread: 2-PLY POLYESTER, 2 FULL STEEL WIDTH BELTS, 1 FULL POLYMIDE (NYLON) CAP PLY
As noted above, the WILDPEAK AT3W uses a 2 ply construction with high-ply turn-ups on all tire sizes, so both our LT version and non-LT 265/75R16 116T are quite robust in terms of sidewall protection and durability. Furthermore, the upper sidewall features of the tire actually protect against rocks and punctures, specifically when aired down, they're not just for looks.
Also, I have owned a Tacoma in the past and used this exact size in both non-LT and LT versions so I can speak from quite a bit of experience on this topic, I have never had any issue with the non-LT off-road around 20psi. On the other hand, if the truck is fully loaded with gear and people, I have found that 20psi is a bit too low and could cause a pinch flat or bead unseat, therefore I usually recommend no lower than 25psi in a loaded off-road application for a Tacoma. Off-road air pressure is a sensitive subject that really depends on a lot of factors such as speed, conditions, load, rim width, driving style, etc.”
“We disected the Cooper AT3 (and Cooper AT3 4s) and found the construction to be a 1ply carcass compared to our Falken AT3W 2-ply carcass with high turn ups. Cooper AT3 4s weighs 41lbs vs Falken AT3W 44lbs in size 265/75R16 SL 116T. Both have the same 14/32nds tread depth in that size. The Cooper AT3 4s is a lighter tire due to the tire construction. I'm leaving factual differences here only...”
Had c load BFG ko2's and the extra weight noticeably affected the power/acceleration of the truck. I had AT3's put on in p metric and it now is...
