I’ve got a 2005 UL which I bought with new Dunlop 5000 tires. Had an alignment done at Lexus Kansas City before I drove it back to Houston. I think the front height is a little high and the rear a little low, always felt this way. After 10k miles I brought it to the local Discount Tire. They can’t rotate the rears to the from, because the rear tires have worn away the inside edge blocks down to the cord level. The car has the stock 18” rims. The remainder of the rear tires look 30% worn, and evenly. There is no cupping which I would attribute to worn shocks. It’s like the entire rear was riding on the inside 1.5inches of the tires.
Im wondering if the low rear ride height can affect the tire wear in this manner? Or do you think it’s mechanical? Seems like they should have caught mechanical issues during the alignment

The "high" position of the UL is NOT for usage during normal driving. The owners manual clearly states that it is only for very rough roads at slow speeds. You are not to use it for normal, higher speeds. Contrast this with the fact that the UL actually automatically lowers the car height at cruise speed in order to reduce drag coefficient and improve stability. Apply this to whatever you are trying to accomplish.

The car is not set on high ride height. My perception is that the front has a good deal more distance between the tire and the fender arch on the front, as opposed to the rear height. May just be an adjustment, or the ride height sensors or adjustment. Techs will be looking at it tomorrow. Not a Lexus dealer, but a Lexus specialty shop. Hoping to. E an informed customer when I show up. Insights here always seem to help.
Please note that the front fenders opening are slightly larger than the rear fenders to accommodate steering. Measure the ground clearances (see red arrows in the sketch below) to determine if your vehicle is level. When the vehicle is level, the front fender arch sits a bit higher than the rear (see green reference line in the sketch below).

Does ride height affect tire wear?
