DJMAXIZA, what made you decide to use the Zeon instead of the AT3? I'm curious because I'm about to put the AT3 on my treg. Also, did you try the AT3 in the 265/65?
Hi Malayaalam, a couple of things. Firstly wanted to get the biggest tyre possible on the Treg, as wide as possible and maximum sidewall height that I could get. Due to the big brake callipers, 18" is the smallest wheels I can fit and so wanted to get max sidewall height for off-road, especially in sand where it needs to be deflated substantially. The combination of max width and SW height, served well in the desert sands and also some rock climbing and general off-road conditions. SW height of the 285/60/18 ZEON LTZ is 171mm against the 159mm of the 265/60/18 Discoverer A/T3. At the time of deciding, the 265/65 was not available.
Secondly load rating. LTZ is 120 against A/T3's 110. As I load the roof rack and car very heavy for the overland trip, as well as tow a trailer with around 350 Litres of diesel, I wanted to ensure best load rating too. Strangely, the LTZ has slightly slower speed rating (S 180 km/h) than the A/T3 (T 190 km/h), but for the purpose of these tires, I cannot see myself do that speed and that is why I got my standard set of 19" Bridgestone Dueler HP Sports...
Also, the LTZ's on the Cayenne wheels, seems to give better rim protection due to the greater width and rim protector lip on tyre.
Another factor is that the LTZ seems to be well rated for mud and snow and looking at the tread pattern, it does look like the LTZ would handle mud slightly better (comparing it to mud terrain tread patterns).
Lastly was the look of the tire. I know it sounds stupid, but I am a sucker for a good looking tyre and tread pattern
I fitted both these tyres (not the 65 profile A/T3 though), before making my final choice and luckily took a picture of the A/T3's fitted. First photo shows A/T3. Second shows LTZ and the small gap when turning wheel. Last two photos shows LTZ's in general.
Hope this helps
Edit: Another factor I considered was that LTZ had slightly larger sidewall blocks, that will give better sidewall grip when in sticky situations. This sounds insignificant, but I think it actually helped me in situations where I got stuck in sand, but could drive out every time, by rocking back and forth, while turning wheels left and right whole time. Not to mention, that last lift on the air suspension worked wonders when I bellied out on crown of dunes before going down a slip-face, and some other ones where I fell in deep by going to slow. Just BTW, the Treg was the only vehicle that did not havre to be recovered throughout the entire 5 days in the desert! I actually had to help recover the guide vehicle once...
