I'll start off by stating we live in central Florida and due to the heat, we experience higher than normal tread wear on our tires, but this seems a bit excessive. We purchased a 2017 Sienna new with Michelin Primacy MXV4s that are "rated" for 60K, but tread was very worn at 20K. We had them rotated every service and saw pretty even wear on all tires. Contacted Michelin, they referred me to an authorized partner who inspected the tires, only 2 were deemed eligible for warranty replacement. The cost to replace through their partner (including 2 free tires) was more than buying another set of 4 from somewhere else and I'd be stuck with the Michelin's that weren't doing the job any way.

Did some research and heard good things about Cooper, so in 2018, at 30K, replaced the Michelin's with Cooper CS5s and was happy with them. Now at 65K we're again seeing what appears to be excessive, though even, wear on tires that are "rated" for 80K, but in need of replacement after 35K. Looking into this with Cooper, but is anyone aware of a similar issue with excessive tire wear on 3rd generation Sienna? If not, is there a longer wearing tire that is good in the heat & provides good traction on wet roads (Florida!)? Thank you.

I have the 15’ fwd xle and in the northeast. The stock Firestone tires needs to be replaced at 25k miles and I put a set of nokian wr g3 tires (60k miles rated) and needs to be replace at 55k miles. Most of the miles in the car are local driving. What you’re getting out of the tires is not unheard of. I guess due to the weight of the vehicle and the type of driving I do. Maybe look into some all terrain tires?

 

Most of our driving is local and while we don't do any road trips, where we live requires about 20-30 minute drive to go anywhere, so we've probably put just over 20K a year. It's good to know from the comments that what we're seeing isn't that unusual. Thank you.

 

All minivans eat tires, with their weight, especially the front ones. The stock tires aren't very good and 30K out of them sound about right. If you do a lot of city driving, 30-40K out of a set of tires might be all that you can expect.

Heck, I only get about 30-40K or so out of a set of tires on my much lighter Camry, but I also only drive ~6-8K a year on average, so they're a lot of local miles.

Some folks switch to a "light truck" tire that withstands wear a little better, but are also more expensive, so I'm not sure you'd actually save any money that way.

 

Seems to be the consensus that 30K is pretty good. Funny you mention your Camry, I've got a Corolla that I drive 4 days a week for my 90 mile roundtrip commute, so that's probably 19K a year I'm racking up. The tires it came with (Toyo Proxes 4 Plus) have just over 30K and they'll need to be replaced soon. Thank you very much!

 

I regard tread wear warranties as pure fantasy.

Tire treadwear warranties are based on 2/32 inch being the minimum acceptable thread depth which isn't safe in rain. The reason I've never been able to make a warranty claim based on tread depth is that there is no way I'm going to drive tires down to 2/32 inch of tread when 4/32 inch of tread is generally regarded as the minimum safe depth for rain.

The minimum safe tread depth for winter tires is generally regarded to be 6/32 inch although I've sometimes driven them down to a little less if it's a mild winter.

I'm happy if I get 30,000 miles out of all-season tires in 3-season use on our 2014 Sienna and 15,000 miles from winter tires. That's about the same as my experience with tires on large RWD sedans over 35+ years.

 

Thanks Geezer1! I agree that tread wear warranty is probably unattainable, if you want a safe ride and I'd rather be safe, especially with rain slick roads we get here. I guess I'll be happy with 30K from an all-season radial.
