They are the replacement for the original LTX M/S, which became the LTX M/S2, then the Defender LTX M/S, and now the Defender LTX M/S2 - just a progression, although some of the previous models are still available some places. Michelin keeps refining their compounds and seem to increase the durability with each iteration. Can you tell I'm a fan? If anyone finds something better, I'm open to hearing about it, but until then, I'll pay more up front because I still avoid the installation costs and inconvenience of having to replace them more frequently.[/QUOT
when I bought my 20/20 recently the dealer wanted to put new tires and he gave me the option of which one and I believe the tires that you're talking about is one that he recommends. And it is a 60,000 mile Tire I believe? I have to look at the sheet. It's a Michelin. The car currently has Michelin Latitude which I believe are the original to the car and they currently have only 21,000 miles and they're a little more than half dead I'd say. So those ones aren't exactly getting great wear on them. I don't know what the previous owner had them set to but the dealership had them set to around 44 when I bought it... I believe. The tire wear is even all the way across the top so it wasn't over inflated or under inflated. I felt the ride was a bit harsh at that mid 40 PSI so I lowered them down to 35 and I like the feeling better. I'm just going to burn these tires up and have the dealership give me the new ones at that time.P.S.... I have seen bad reviews on the gx460 where the author was saying that they have a terrible ride they ride like a truck blah blah blah. Well I think they probably just have the PSIs too high, because I like the ride of my GX it's smooth comfortable handles well does not pull to the left or the right does not lean to the left or right I like my truck. I also have a 20/20 Toyota Tundra and that is definitely a truck and it rides similar to the gx460 but a little bit harder.... but honestly I think the difference between the two vehicles is the seats on the gx460 are a little more comfortable

 

[QUOTE=Toejab;11914525][QUOTE=bdcurnutt;11913955]When we bought our 2019 (and my 2005 RX in 2016 before it), the big dealership in DFW area was putting on OEM Bridgestones or Yokahama tires, but our 2019 came with Michelin Latitudes, which only had a 40,000 mile warranty. although the aftermarket Latitudes now have a 55K mile warranty (at least on Tirerack.com) vs. the Defender LTX M/S2 with a 75K mile warranty and which I have gotten 90K out of on my Suburban. That's why I asked them to put those on my 2019 GX. I have about 50K on my current set of Defender LTX M/S (the previous version) on my Suburban and still have almost half the tread left - they are just superior tires and only cost a few dollars more per tire. Michelin is rated #1 in the industry and Continental probably is 2nd overall, but Michelin purchased BFGoodrich several years ago (as well as Uniroyal in the US) and they have continued to improve also. They also own Riken, which is a little-known brand, but are good quality at a cheap price, if they have your size. If you need more convincing, just got to Tirerack.com and Discounttire.com and read all the reviews in chronological order and you'll be stunned at the number of people who've gotten phenomenal mileage out of the Michelin LTX M/S series (Defenders now), including on heavy duty dualies. Yes, you will find a few detractors, but they are the exception. If you buy them for your GX, set them no lower than 35psi or as high as 44psi (based on my personal experience) and you will get long life out of them, with the added benefit of them being quiet. I had my Suburban in the Colorado mountains over Christmas with about 13" of snow that week and even though the tires were several years old, they did great with 4WD engaged - no chains required. I can't wait to try out the GX in the snow - it will probably be very anticlimactic.

 

Remember, the higher PSI you go on your tires, the harder things are on your suspension. Don't tires only display a max pressure? I would definitely not go up to that pressure. Perhaps Toyota makes their recommendation with suspension and vehicle weight in mind for a particular tire size as listed on the sticker. Just because a tire can handle more pressure load, doesn't mean you need to pump it up to max. If the vehicle isn't heavy enough, then the centre of the tire tread would wear wear faster. Again, for me set it to 32psi and foggetaboutit.

 

^ ... or hey, just adjust the pressure for "comfort" ... Ford must have known what they were doing to accomplish exactly that at 26-psi (door-jam placard) with the Ford Explorer ... with the 238 dead people and 500-odd injured being extremely comfortable up to the point of testing their ability to steer out of a rollover ... the story is well documented. Toyota "dumbed down" the suspension on their body-on-frame vehicles to compete ... following the Explorer lead which was the #1 selling vehicle in that category at the time. Well at least we had TPMS imposed on the auto industry as a result

The GX is a Truck ... body-on-frame ... with a solid rear axle ... so will never ever be as "comfortable" as a soccer mom "SUV Cute-Ute".

 

Does anyone still use the chalk line test to determine a good tire pressure?

 

nope. Have not figured out a precise measurement for any car. i just test it out to see what fits best for a given setup, and observe tread wear/dust patterns on the tread blocks to see if im on outside the optimum bell curve of psi.
