yup. our van ate hydroedges for breakfast, lunch, and dinner. i think most i got out of a set was around 20k miles before it got down to near the wear bars on a couple of the tires (fronts, i think).Has anyone taken the vehicle to Costco for mileage warrienty.

they could've gone for a bit further, but in the rainy season, i didn't want to chance it so went back to pick up a new set.
didn't expect them to honor the mileage thing since i was changing out early (before they were all down to the wear bars) but costco (at least the one i go to) was nice enough to prorate them at the time instead of having me come back when they were all completely bald.
The Sienna tire wear issue has been discussed in detail. Many owners have experimented with this and come up with the following advice...
1. The van is too heavy for Toyota's 35 psi tire pressure recommendation. Anyone reading this should increase their tire pressure to 40-44 psi in front and 38-42 psi in the rear on FWD models (40-44 psi and the same, front and rear, on AWD models) if you want to get reasonably good tire wear. The van also gets better gas mileage and handles/brakes noticeably better at these tire pressures. The cost is a SLIGHTLY stiffer ride, but not objectionable.
2. The Sienna is front heavy and will wear-out front tires twice as fast as rear tires. YOU NEED TO ROTATE THE TIRES if you want to get reasonably long life out of a set. This needs to be done at a minimum of every 5000 miles and a maximum of 10000 miles.
I keep my tires at 40 front and 38 rear, rotate them every 6500 to 7000 miles, and get the van aligned when I buy a new set of tires. I have not gotten less than 45k miles out of a set and I got 59k miles out of a set of Michelin Primacys.
My 2005 Sienna XLE with 215/65r-16 and just over 86,000 miles is almost due for the 4th set of tires, Dunlop's original, then Michelin's now Sumitomo's, 86,000 divided by 3 =28,666 average. I decided I will try Michelin's 225/70r-16 LTX M/S2 and got a quote from Sears and probably will have them installed within a month. Sam's Club price is a little less but the tire manager told me that it's against Sam's policy to install any tire size that's not on the door plate even though the LTX tires are rated higher all around, higher speed rating, higher load rating, higher tread wear, & higher heat rating. Seems crazy to me that Sam's has this policy. After I get them and put some miles on them I come back to this forum with a report. 12/13/14 I have about 5 months and 5-6000 miles on them and I will be having a balance & rotation done next week and they still look like new. The speedometer now is more accurate with these tires. The van handles and rides better than ever.[/Q
That's great! What effect has it been on your miles per gallon?
Responding to an old thread here, but thank you for that explanation. I think that's exactly what's going on with my 2006 LE. Tires wear quicker than I think they should, mostly on the inner and outer edges. At times my steering "wanders" just a tiny bit, but steering response is tight enough that I don't think it's in the steering or tie rods. All the linkages feel pretty tight, but with the suspension hanging down (on jack stands) the rear of the lower control arm looks like this:So lets discuss why the tires are not lasting very long.
If your tires are wearing out, check your suspension parts. These vans have a front lower control arm with a bushing that wears out. The rear bushing is a big rubber doughnut and when it fails it allows the toe setting to move all over the place.
How do I know about this? My Lexus IS300 has the same setup and it chewed up my tires inner edge way too quickly. I pressed out the torn rubber OEM bushing and pressed in the new poly bushings. The toe setting is rock solid now. The poly bushings did not stiffen my suspension at all. It just keeps the lower control arm from shifting rearward upon braking which is when the tires are being worn down unevenly. This is magnified because the van is front wheel drive. When you brake, the inner edge wears quicker. When you accelerate, the outer edge wears quicker. Net result, your tires last half as long.
Even if your bushing is not torn, it maybe too soft to retain the alignment setting while driving.
Not worth it to bother with aftermarket bushings as they don't last long. Just get factory oem and be done with it. They aren't that pricey. A little less than $200 each side if you look around.Responding to an old thread here, but thank you for that explanation. I think that's exactly what's going on with my 2006 LE.

Not completely torn, but definitely separating somewhat.
I see that the control arm bushing can be purchased by itself, or included if you buy the whole control arm. How hard is the bushing (and it's steel sleeve) to remove and reinstall in the existing control arm??
