Was just trying to help. I don't think I said anything that was offensive, so I don't know why you don't wanna hear or believe what I was trying to say. Just stating the same facts that others had mentioned

Lexus has known of this problem since at least the last generation IS:

Why has this not been corrected!?

dbs600, assuming you maintained a 36 psi tire pressure throughout, did you get Lexus to check your camber? Looks to me you could have too much negative camber resulting in the premature wear on the inner edges of the tires.
Took mine out when I got new wheels/tires at 12k miles. They have worn evenly and have about 60% tread left at the front, 50% rear.

Camber can usually be adjusted only so much. A lot of folks mistakenly think it is camber that wears the inside edge of the tires...usually because it makes sense from looking at diagrams, but actually toe is the much bigger enemy for tire wear. You'll want to have toe put close to zero. Interestingly it is toe that can wear the edges like that too.

I can run -1.5 degrees camber and get zero inside tire wear with the correct toe settings. But, yeah, the tires do blow and the alignment should also be checked.

My Bridgestones OEM lasted for 26k miles. I could have gone more and they definitely didn't look like any of the pictures you guys had. Mine were 50/50 freeway city miles. I couldn't wait since those OEMs were so crappy. I got a set of Michelin Pilot Super Sport now and those things grip like no other. No more squealing leaving a parking lot anymore

Great video, 2015isboy! Loved the sarcasm; very funny!
Also nailed it regarding interior ergonomics and the infotainment system.
Any thoughts on the outer tire wear mentioned? Inner tire wear is the issue.
Thanks again!

What a great video, 2015isboy!
Loved the sarcasm - "I don't think", "Always at the back", "I wouldn't buy it", "Anything else", "Really directive [air ducts]", "8 cyclinders", "They're not that intelligent". All very funny! He also nails is regarding the interior and infotainment.
Any thoughts on the 'outter' (not 'inner') tire wear mentioned? 'Inner' tire wear is the issue.
Thanks for sharing!

This is absolutely correct. Negative camber will usually negatively affect long term tire wear when it is greater than 2.0*. I personally am fairly picky about it and will address lowered cars when the camber is 1.8-1.9 or greater. Pictured is my wife's car. I did align it for the first time a couple months ago after I lowered it. Currently has 19,400 miles on the stock Turanza's, perfect wear pattern, and 6/32 tread left on front and rear.
Did you use factory alignment specs or something else, like others?

Check out my posts in this thread (about #18 up) for some fairly good info; but basically the front camber ended up at .8-.9* neg; toe as close to zero as possible, rear camber at 1.4* neg.
