Might as well add batteries that die in two years to the lawsuit as well...

 

The OEM tires lasted to 35k miles, which is more than I thought they would last. The treads were at or very near the wear bars and we did have some inside wear (due to the suspension setup of the minivan). I replaced them with Cooper CS5 and we currently have 67k miles on the van. Tires are rotated every 5k miles and are wearing evenly. Tread depth is 5/32.

What tires do you have on the van? How often do you rotate the tires?

With this being my second minivan (2004 Nissan Quest was my first), I know that minivans are notoriously hard on tires and brakes. If you get close or over the mileage rating, congratulations! You're in rare company. The only advice I can give you is get the alignment done when you buy the tires and rotate them every 5k miles. The Sienna suspension setup is for ride comfort and if you don't rotate your tires, they will wear on the inside of the tires. There is very little adjusting that can be made with regard to toe and camber.

What kind of class action lawsuit do you have in mind?

 

I heard that the inflation information for our vans is incorrect. To correct the uneven wear you need to inflate the tires between 38-40psi. My runflats only lasted 21k and I felt unsafe if I pushed it to even 25k. I have the General Altimax running 39psi.

 

To address what has been posted by the OP and others ...

The 18" Goodyear tires that came on my 2014 Sienna were wearing very evenly when I replaced them all at about 28,000 miles of use due to ruining one. And my winter tires (Bridgestone Blizzak WS80) also have worn evenly over three winters and 15,000 miles of use.

My original battery is still working at 3 years, 3 months although it displayed some weakness a few weeks ago when I had to start the engine in order to "power stow" the second of the two third row seats on a very hot day after I had already power-opened both sliding doors and the rear hatch door. It's been working fine since then.

When I checked brake pad and rotor thickness a few weeks ago at about 50,000 miles, I found very little wear of the pads and no measurable wear of the rotors. At the current wear rate, the rotors should last the life of the vehicle (200,000+ miles), the front pads should last 100,000+ miles and the rear even longer than the front pads. These findings and estimates are consistent with what we have experienced on a number of previous Toyota and Lexus vehicles over a total of 500,000+ miles.

I've always suspected that the reason we get so many miles out of tires is that I'm rather obsessive about tire pressures. My goal is to never let tire pressures fall below the manufacturer's recommended value which takes some work since tire pressures increase/decrease by about one PSI for each 10 degrees of temperature change.

 

Has anyone challenged Toyota about the excessive tire wear? We just had our tires change 15K miles ago by Toyota with alignment and the tires are excessively worn on the inside.

Every 5k, we've been getting them rotated and we were informed by Americas Tire that they wouldn't rotate them any longer due to excessive wear on the front inside tires.

Excessive wear, yes, the dealer does free oil and tire alignment every 5,000 miles for the first 25,000 miles. The dealer does does drive by alignment with lasers and this does a very poor job. No check on toe alignment. So in about 30,000 miles tires are worn bad so that tires are shot at about 35,000 miles

 

My tire wear problem is fixed. Previously, parking lot turns of more than a few degrees would squeal the tires like crazy. Outsides of front’s tread ground off quickly.
I had the toe set to zero (no toe in/out); problems fixed. No more squealing or outside tread wear. My old tire shop had been locking in a positive toe (toe in) to provide “safe handling.” BS. They knew it was grinding the tires right off.
Also, I put bigger tires on. Now my Speedo reads accurately, I feel like I’m setting up higher, and it handles bumps better.
Also put a spring bag lift in the rear that I run at 20psi constantly. Makes it ride stiffer and keeps our butt up off of the pavement.

You probably don't need to go to zero toe. A tiny bit of toe adds straight-line stability and shouldn't kill the tires. Do you know what the Toyota spec is and what amount of toe the tire shop had been setting?

 

recently bought new tires. upping the air to 42psi has so far yielded even tire wear. we also try not to do sharp turns (at full wheel lock) if possible. I plan to rotate the tires at every oil change (5k).

 

On my 2008 I went up in size to 235/70r16" Pirelli Scorpions. It is the biggest positive improvement I've made. It corrected the far-off speedo perfectly so it racked up miles about 4% more than indicated. It improved handling immensely, lots less roll and I like the feedback with much less rock and roll. I did it mainly for more ground clearance which it did give me over an inch. Good grip in snow too, these are 3mps rated. I'm hoping these will also fit my 2015 LE if the rotor clearance works out, since they are near new and mounted on separate wheels (Saturn wheels, fit great and look unique).

 

I am on my 4th set of tires on my 2011 Sienna (2013 @24k,2015 @ 46k mi.,2019 @ 75k mi., 2023 @96kmi.) I have had lifetime wheel alignment since 2013 and therefore have tires rotated, balanced and wheel alignment every 5,000 mi. It would be easier for me to take if this was my daily driver, but it is not. My wife drives very slow and careful, and uses it 99.9% of the time. I only drive the van when we go on road trips, so we can get there before we die of old age and Home Depot runs since I got rid of my truck. (Bad decision) Speaking of my truck. It was a 2000 V6 Prerunner and had just over 100k mi. on its Goodyear Wrangler tires before being replaced. And even then they had tons of tread, but were so dry and cracked from age I could not start from a stop on a hill in the rain without feathering the throttle . Driving in wet conditions was scary and fun at the same time. I searched everywhere to find someone who had the exact original tires and had them replaced. Sadly they did not last long. I think just as paint has changed for the environment, so have tires, and with that goes longevity. Like others have said, keep up on your rotation and take advantage of the tire warranty. I would not waste your time on more expensive tires as i have tried several and just reverted back to the lower cost FR710's. I haven't tried inflating above the recommended 35psi ,but will give that a try with this set I literally just about an hour ago.

 

Why must everything result in a lawsuit? Your tires wore out early, okay why do you assume its Toyota's fault? Why is it not the fault of the tire manufacturer? Or heavens forbid, the fault of the driver. Don't know how you drive, but certain driver and use characteristics are far more likely to affect tire wear. How much load do you carry on average, do you drive fast, brake hard, take sharp turns. Do you have a roof carrier, do you live in a hilly our mountainous region? Maybe a bad batch of tire compound from the tire manufacturer. Just a pet peeve of mind, but I hate it when the first thing out of someone's mouth for a problem is a lawsuit. There, got that off my chest, now carry on..

 

I've always run my tires a bit high, but have only run my Sienna at 35. After reading through the comments here I think I'll go out and give them all a little boost to 40.

 

We are on our second set of General Altimax tires. Pressure set to 35 lbs. First set had over 50K miles when replaced. First set of OEM brake pads had 90K miles when replaced for Akebono pads and OEM rotors.
We also have Air Lift helper springs and Megan Racing rear sway bar. The Sienna takes turns more car-like with much less body roll and predictable braking.
