Costco Tire issues/questions

I used to work at the Costco garage in Windsor, ON. That part-time job is actually what got me into the tire industry 5-6 years ago.
So far, a lot of the info on Costco's policies that has been posted is pretty accurate.
Costco had very strict rules back then, and we always enforced them. As staffers you can get reprimanded or lose your job for not following the company's tire installation policies. It does have to do with liability issues as has been mentioned. Costco as you know is a massive company, and they aren't going to risk lawsuits or even bad publicity to satisfy us with over sized tires. Sucks for us, but they are just protecting themselves.
There is the trick about dropping your rims off and getting them to mount and balance the tires, but you won't get the rotation service even though you are still paying for it. They will still fix any flats you get, but you'll have to bring the tire on the rim off of the vehicle.
The manager at my location was pretty cool about the oversized tire thing. If you were a regular customer, he'd usually help you out around the rules.
But like every other customer service job, it's the employees that make the difference.
They had specific policies covering the re-torque after 1oo km, as well as the speed rating that Rob mentioned.
That's another liability thing, and is a widely accepted rule within the tire industry. Various cars come from the factory with suspension systems setup to work and handle in a certain manner based on a certain level of stiffness that the tires provide.
Changing that element (tire speed rating) changes the dynamics and handling characteristics of the vehicle.
If you're a good driver that is actually aware of the specific handling characteristics of your car/truck/SUV and take that into account when you change the various components of your suspension system, including the tires, then you'll probably be fine and experience no real issues. You've likely adjusted your driving habits to compensate accordingly.
But, with our society being overly sue-happy, and the lack of self discipline along with not taking responsibility for one's own actions, they've adopted policies to protect themselves. People drive their SUV's as if they are supposed to handle like a Ferrari, and they're designing vehicles that can park themselves.
Can anyone really blame Costco for taking this stance?
Another thing about Costco that I try to mention a lot - their business plan that has to do with the garage facilities. The tire shop/garage is not designed to make money on it's own. The markup on the tires is quite low compared to other tire shops, and the oil changes are quite cheap as well. They also pay their employees fairly well and offer a decent level of benefits, especially when considering the low standards that are often present in independent tire shops.
The tire shop components of a Costco warehouse are present solely to keep members inside and shopping. ;)

Back to tires...
I'd personally be somewhat hesitant to go to a tire shop that is willing to satisfy almost any request by the customer just to make that sale.
I deal with tire shops over the phone every day, and it's scary what they try to do sometimes.
I had one guy last week trying to get his customer into some S-rated tires that were slightly undersized for the rims on his BMW M3. :Wow1::Wow1:
And just today i had to give a verbal lesson about ply ratings and the difference between bias and radial tractor tires and why you're not supposed to mix and match them on a tractor. This was to a guy that worked at a place called "Lawn and Tractor" something or other...

Some tire shops are good, some, just run away from!

This is what I have a problem with. The connection between sidewall stiffness and speed ratings across tire manufacturers is tenuous at best. It's very easy to have a tire with the same speed rating as eachother, but one of them had MUCH lower sidewall stiffness. Not to mention the fact, you have completely ignored the aspect of the actual rubber compound and it's friction coefficient. That can also change within a speed rating.

Of course, they wouldn't hesitate to sell you a *higher* speed rated tire, which can have a host of problems. Not the least of which is high speed rated tires can often have compromise tread designs that do not clear water as well as other all-seasons. Causing the customer to lose control in the rain. But nobody seems to care about that, as long as the customer is spending more on tires.

It's a dangerous game to play, and the logical conclusion to it is that tire shops will only be able to install OEM tires, and nothing else. No snows, no +1 sizing, nothing. Is that really what they want?

And while we're at it, you should really have a look at this. Executive summary: High performance low-profile high-speed-rated tires actually make an SUV significantly more likely to roll over than the OEM tires. High profile, extra-tall, A/T tires actually make the vehicle less likely to roll over than the OEM tire.

Wal-Mart, Costco, and BJ's are all the same on their policies. They will not put larger tires then what came factory on the truck.

Check out Rimzoneonline they are a good company to deal with a buy tires from. Last time I checked on a set of Nitto's for my truck they were around $200 Cheaper on the tires than any other company around. They ship, and can mount and balance as well.

I agree with you on a lot of points Rob, ESPECIALLY regarding the variation in tire stiffness/quality of compouds etc. between the different tire manufacturers and even the different lines of tires that they produce under their "umbrella".

Bt that's the industry, and they've trid to come up with some standards to try and stick with.

I'll read that link when I get time today - shouldn't be hard, for some reason it's always quiet on Fridays. I guess people don't go to tire shops on Fridays??? lol

Oh Rob, if you really want to get mad about tire industry standards, start looking into the UTQG ratings. That whole rating system is a complete joke!

You now, hey, Costco would theoretically put a set of these on. DOT legal and Z-speed rated. Good to go! :D
