Hello. As the title indicates, I am a current owner of a 2018 Sienna SE, which we bought in 2018, replacing the 2006 LE we drove for the first 12 years of its life. Currently in the market for our third set of tires, which is what brings me back to the forum.

Welcome. I made a similar upgrade last year, from an '05 LE AWD to an '18 XLE AWD.

Tires? Lots of opinions on the forum. Not sure if your SE has different sizes than my XLE, but since I have (had) run-flats that were getting close to replacement, I replaced them within a few weeks of getting my van. I have used Michelin Defenders in the past, went with them again. Got the same width (235), but went up one size on the aspect ratio (60, instead of 55). That made the tire just a wee bit taller, which made the speedo agree with my GPS and give a slightly softer ride in the process. Yeah, most of the ride improvement was due to getting rid of the run-flats, but I prefer the 60s over the 55s anyway.

Point well taken about the 60s vs the 55s. I love the looks of the SE, which has 19" wheels, but the ride leaves something to be desired. Low profile tires seem to be what you get on the high end trim lines on nearly all vehicles today, though.

Ours had Michelins from the factory and they lasted only 24K miles. Went with Yokohama Geoloandar CV G058 for the second set, mainly because of good past experience with the brand and also because of their weight rating. While they lasted 34K, we were never happy with them. You could hear every rotation from at least one of them (a sort of flutter) and they were the noisiest tires I've ever ridden on. Although their ratings are very high at Tire Rack, they were certainly not right for that car. I'll always believe we had one bad tire, and the experience has shook my faith in Yokohama a bit.

Ended up going with Firestone Destination LE3, which was influenced heavily by what my local shop could get in that size from his wholesaler, and after only three days, my wife's and my initial reactions are that they were an excellent choice. Much quieter and smoother than the Yokohomas, and I'm going to run them at 40 PSI in hopes of preventing some of the outer wear that so many have experienced.

I posted a bit more in this thread: Sienna SE tire options

They must have not been Defenders.

I have been running all my tires about 5psi higher than recommended (but not exceeding the maximum on the sidewall) for many years. Yes, it seems to reduce the wear on the edges of the tread without wearing out the middle.

My Defenders usually last 60-80k miles.

Oh, wow. That kind of mileage on these vans is amazing. Depending on how well these Firestones do, I'll definitely consider the Defenders next time. The OEMs were Micheline Primacy, I think, but I don't remember which sub-model. The two I'm seeing on Tire Rack are the MXM4 and the Tour A/S, but I don't recall if it was one of those or not. I was shocked when they were about shot at 20K. I didn't stay on top of the pressures, though, so lesson learned.

Depending on how you search, you might not find Defenders for your van. I think I remember that the exact size is not available (235/55), but I wanted to change that anyway. I wanted to go to a 235/60 for the slightly taller tire to correct the speedo error. The speedo now agrees with my GPS (and phone apps), but the odometer is about 2% slow. Accurate speed is more important to me, as I don't have to calculate every time I look at it. I only worry about accurate mileage when I calculate MPG, which is considerably less frequently.
