I have a 2006 LE Sienna with 80,000 miles. I put the Michelin X-radial on at 42,000. I rotate tire's every 4,000 to 5,000 miles. I"m getting major wear on the outer edge of 2 tires. Tire pressure is always checked. Costco said I have 2/32 left before the wear bars. They come with 11/32 of tire depth. Anyone have odd tire wear problems?

I have a 2006 Sienna XLE. I changed the original tires at 31,000 miles to Michelin X-radial. It has 54,000 miles now, but the thread is down to 5/32 with only 23,000 miles on it. I am going to change the tires soon. The technician told me Sam's club will prorate the tire for me, but I definitely will get different brand. No more Michelin tire for me. Unlike yours, my tires wear evenly. By the way, we drive highway and local 50/50.

Which tires are you going with?

Not me... but which two tires are wearing this way?

Would it be the front tires??? Sienna's will shave the outer edges of the front tires due to 'scrubbing' of the edge of the tire on the outside of a sharp low speed turn. Its what they do as the tire knuckles under in the sharp turn. I suspect that you are running the factory recommended 35psi in the tires? The fronts could probably should be increased a 2 - 3 psi over the door placard. This will help but not prevent the scrubbing of the outer edges of the front tire. Rears could use maybe 1 to 2 psi over the factory recommendation.

could it be too much positive camber? after changing the shocks/struts, our sienna pulls strongly to the right. had it aligned twice, but now i'm suspecting something was incorrectly installed because i'm noticing abnormal tire wear on the outside edge of the right front tire.

rotated tires, car still pulls to the right, and now the new front (formerly rear) tire is showing abnormal tire wear after only a few days.

car goes back to the dealership to have the install checked. i've heard that on some camry models, incorrectly installed struts can cause steering pull.

I have ordered the 215/65R16 98T Goodyear® Assurance® ComforTred® Touring from Sam's club. Should be in next week.

The odd wear is on all 4 tires, but more on the current fronts. Toyota did my alignment and everything was with-in spec. Today I put new X-radials on from Costco. They prorated the wear and I was OTD for $200. I love Costco customer service. They guys in the tire shop at Costco said that have seen the same tire wear on the same year van before. They had a 06 sienna in the shop yesterday and the lower a-arm bushing were gone they said. Like 3-4 inches of movement from the missing bushings.

How many mile do you have on your van?

Excessive wear on EITHER the inner OR outer edges of the front tires is an indication of an allignment problem (typically tow). Excessive wearing of BOTH the inner AND outer edges of both front tires is an indication of underinflation, excessive wearing in the center of the tire's tread is an indication of overinflation, nothing else causes these types of wear.
You will see this on the Sienna's front tires because of the higher front weight and the greater amount of work that the front tires have to do. Because of the underinflation wear evidence, the factory recommended 35 PSI is obviously too low. There has been MUCH discussion about this problem in both this forum (do a search) and the previous Sienna forum. After much experimentation, many Sienna owners have concluded that 40-42 PSI in the front tires is the CORRECT pressure to run to achieve even tire wear (regardless of the MAX tire pressure listed on the side of the tires) and regular tire rotations are absolutely necessary if you want to get maximum life out of a matched set.
For myself, after several years of experimentation, I have chosen to run 40 PSI front and 37 PSI rear as my cold tire pressures. I check them once a month (or whenever there is a dramatic outside temperature change) and I rotate them front to rear every 6-7k miles. At the pressures I have chosen I'm getting even wear all the way across my tire's treads and I have achieved excellent wear results.

wag : what mileage are you getting out of set(s) of tires ? some of the members are getting low numbers ex. 30k wow that's low

Based on what expected mileage? Down to 2/32" from 11/32" in 38,000 miles suggests about a 40,000 mile life; thanwu is down to 5/32" from 11/32" in 23,000 miles suggesting about a 42,000 mile life. What expected life did Costco use to calculate a pro-rated cost?

By comparing to an image of the Michelin X-Radial in new condition, it is apparent that the wear is signficantly greater on one edge (presumably the outer); the X-Radial is symmetric, but the worn tires look like near-slicks... only on one edge. The wear appears to be quite even across the rest of the tire, and the outer edge will wear faster if you turn (only on the right side if you race in NASCAR

).

I don't see any underinflation wear evidence, only evidence of a lot of use turning corners (such as urban service) or perhaps misalignment (toe or camber) causing somewhat accelerated outer edge wear. The wear is not feathered, so it seems unlikely that there is a serious toe-in problem.

I agree that the pressures wag describes are likely optimal for tires that can use them, and the X-Radial has a maximum inflation presssure (the number listed on the sidewall) of 44 PSI so 40 to 42 PSI would be fine; however:

I don't think the wear shown indicates that more pressure is necessarily needed; and
I do not agree with using pressures in excess of the sidewall maximum and against the directions of the tire manufacturer.

My first set of OEM Michelins only lasted 36k miles, but, for the first 10000 miles I was running them at 35 PSI and the inner/outer edges were worn noticeably during that time which shortened their life.
Since I bumped the pressures up to 40/37 my tire wear has been markedly reduced.
My second set of Michelins are getting close to needing replacement now (but not quite down to the wear bars yet) and they have over 50k miles on them. Given the van's weight, I think that about 50k miles is going to be about the MAX that any tires will last, regardless of the tire's mileage warranty. I'm OK with this, I feel that at 50k miles, I have gotten my money's worth out of them.

My OEM tires are Michelin LX4 which was replaced at 31,000 miles. I keep my Sienna tires inflated properly around 36psi. I would say 30,000 miles out of the 55,000 I have on the Sienna are highway miles. Anyway, my experiences with Michelins are really bad. No more Michelin for me!!!

I agree. When I got my OEM LX4s replaced with Hydroedges at a pro-rated price, the person at Discount Tire was pretty sure I'd come back before the 90k mile tread warranty for a replacement.
My Contour has the Hydroedges for the last 48k miles and they probably won't make it to 90k miles either so I doubt it's just the weight of the van.
If they last more than 50k or 60k, I've got my money's worth just like wag, and tread wear is the least of my worries from a tire.
I'm quite happy with Michelin after reading about other tire issues on this forum.

It seems likely to me that the treadwear warranty distances are based on typical use, and that every brand and model of tire on a second-generation Sienna - particularly in the 16" size - will wear out too early because the tire is being used close to the limit of its capacity, especially in the front. More typical vehicles don't push the tires so close to their capacity, and are more likely to survive the stated distance.

For comparison, look at mid-sized SUVs which weigh about the same as the Sienna and carry no more load - they have significantly larger tires, which will probably last longer.

Just speculation.

mine is (brought it new) 2007 sienna LE with 23,000 miles and still with the original Dunlop's tires. I'm also getting major wear on the outer edge of the front 2 tires and the rear tires are still like new.
