Toyota Sienna minivan tires

Is it the same brand and type of tires for all 3 sets?

How many miles do you get on a set of tires?

The first set of 4 tires, the one that came with the car lasted close to 24K miles. The 2nd set which we are still using 30K miles.

same brand for all 4 tires. General... I guess 30K is not that bad for the 2nd set of tires.

I have a 2015 Sienna XLE. The OEM Michelins lasted 30K, alfter 3 alignments - Some outside edge wear. Since I used to be a mechanic I adjusted the Toe out 2mm and put on Goodyear. I started to notice inner edge wear and 4/32 wear in 12K. Also front camber is about 1/2 degree more negative now vs when new - maybe some suspension/frame settling. I actually prefer this for turns but since to wanted to stop inner edge wear i adjusted Toe back 1mm to Toe in and will monitor tread wear. The from steering geometry on the Sienna is not holding toe properly parallel when turning - this is causing tire wear. Even if the Toe is good going strait it is off when turning. I am trying to find the best setting for average.

I have a 2017 with RFT and have 32k on them. The last 6k has had uncomfortable noise coming from the front tires. I went to dealer and two tire shops, the two tire shops showed me the extreme inside wear on the tires. Before the rotation 6k miles ago, I heard nothing unusual from the road. After the tire rotation and alignment, the car sounded like my old 1955 ford with bad bearings. About that time, I investigated. Previous comments by others confirm that RFT and inherent problems with alignment are the problems. Likely, I will convert to NRFT tires because of the increased mileage and reduced cost. I have not read about any real negatives in doing so other than finding space for a spare or going without a spare. I wonder if the use of "dynamic" traction control using magnetic particles clutches result in uneven wear, particularly when turning under power. I suspect there are tradeoffs when using these devices. Any thoughts or science about these wear problems.

I forgot to mention that before the alignment there was no discernible or uncomfortable noise coming from the car, one tire shop stated that noise became noticeable when back tires came forward. They double checked alignment and it was w/i specs, however I am unaware of how much the alignment was out of specs before the alignment after 36k.
