Yeah, but i am just a chickensh!t to make the jump to such a skinny tire…yeah, you guys have told me about the benefits……just afraid for safety of my family on a road trip with such a heavy vehicle on tires that are so skinny compare to what Toyota engineers intended.
I would not worry about the ‘skinniness’ of the tire - the load rating of 2756 is the same for the defender in a 275/65/18 and more than the 60 profile (non LT tires).
I have been running the Defender LTX M/s LT265/70/18 for about 100k on my 100 . 2 tires swapped due to road hazard by 80k (nails), then a damaged tire after road hazard expired, so I bought 2 new tires and total Defender miles is over 120k. I have another 40k of life at this point.
Hydroplaning: No issue with the 265’s. Curious what size tires are experiencing hydroplaning? Handle very well in the wet, standing water can be a wiggle or jolt if on one side (I need to slow down, because at that point my windshield is covered with water

). Tires have spent a lot of time in New Orleans (63” rain per year) and Tampa (50” rain) - so lots of rain driving, as well as freeway miles.
The Trail’s look interesting - at 39 lbs about the same as the non LT Defenders. LT’s are 50 lbs.
Defenders work well on gravel, dirt, rocks, easy sand, snow - I have avoided deep mud - obviously not designed for it.
LT’s were installed after bubbling 2 P-rated BFG sidewalls within 6k of mounting (warrantied by Michelin). I drive easier Jeep trails - with a 400 lb (motorcycle) trailer hitch carrier.
My other 100 has P-rated tires in stock size - ‘rides’ much nicer but handling is sloppy compared to the LT truck. I think the LT’s behave like a low profile tire - not much sidewall flex and harsh hitting potholes at speed (also this truck has heavier springs and shocks, mild lift). Just bought some 17” rims for truck #2 and doing a tire-search now.
The LT Defenders handle pretty well with the motorcycle on the back in mountain roads. Truck definitely has some oversteer on corners, but predictable, and I drive ‘assertively’. LT’s are smooth on the freeway.
Buying tires for truck 2 is difficult - I know I will be trading the ride/mileage of the Defender’s to get some off-road capability and (honestly) off-road looks. I have read most of the tirerack tests and reviews (especially the low star ratings) and am leaning towards the Falken A/T3W’s in LT 275 or 285/70/17. Will be interesting to compare to the Defenders on truck #1.
