My wife came home after service at the local MB dealer with a "free" vehicle inspection report. Looks like we'll need new tires soon.
Coincidentally (?) got an email this morning from the same dealer:
"Save $150 on a set of 4 tires on eligible tires tailor-made for your Mercedes Benz..."
So I spent a few minutes doing some comparison tire shopping between MB dealer, Discount Tire, Tire Rack, & Costco. Costco also has $150 savings on set of 4 Michelin also ($70 off tires + $80 off install)
So for my 2015 E400 sedan, with 245/40R18 fronts & 265/35R18 rears,
MB came up with 9 sets, with Pirelli, Continentals, & Michelin.
Discount Tire & Tire Rack has 45 & 31 sets respectively, & has lots of other brands. Amazingly both has the exact same pricing on most of the sets
Costco has 3 sets each of BF Goodrich, Bridgestone & Michelin. Michelin pricing is exactly same as DT & TR
Here's some sampling of a few sets I'm considering for comparison, prices front & rears, without installation:

MB Discount Tire & Tire Rack Costco
OEM Pirelli P Zero Front $195 $176
Rear $248 $191
Pirelli P Zero Nero A/S Front $219 $183
Rear $251 $207
Continental Extreme Contact Sport Front $209 $182
Rear $243 $202
Michelin Pilot Sport A/S 3+ Front $238 $185 $185
Rear $268 $218 $218
Michelin Pilot Sport 4S Front $250 $205 $205
Rear $295 $252 $252

So if I plan on sticking with OEM Pirelli P Zero, it's $868 installed (after $150 discount) at the dealer (dealer charges $33 per tire for install) , or $734 at Discount Tire + install
But if I plan to change to Michelin Pilot Sport 4 S, it's $1072 installed at the dealer after $150 discount, or $914 for tires at Costco minus $70 off (the $80 install fee offset) = $844. Looks like Costco is a $228 savings vs dealer.

 

From what it used to be - Costco also include road hazard insurance and lifetime balancing?

 

Costco for sure in this case. I use Discount Tire because I know them, they are close and they are competitive. Tire rack can be a pain if ordering and shipping gets messed up.

 

I used Costco for tires for a long time. A few years ago Costco put tires on my truck, and the road noise was terrible. I got in the middle between Costco blaming the alignment and the alignment store blaming Costco.

Bottom line for me is to have one place that do balancing and alignment. On my older Mercedes, I had very good service from Tire Rack, since my mechanic is also a Tire Rack recommended installer.

 

I had Contis on the car that were installed by the dealer when I bought it about 5 years ago. Got 35K out of them and they still had about 10K left. Put a set of Conti Extreme contacts on it that the MB dealer had a special on. Price installed beat tire rack and everybody else including road hazard. A couple of weeks later I picked up a nail in one tire, brought it back. They gave me a loaner and told me I was getting a new tire. Nice.

I thought the newest set of Contis was noiser than the older set, but after a few thousand miles they quieted down quite a bit. Handling on both sets is great. I liked them so much I put a set on the wifes Avalon. Contis tend to rate about the same or a bit under comparable Michelins, but for a much cheaper price.

 

You didnt mention reviewing customer reviews for each tire for noise, stopping, snow etc
Changed one brand after 2/3 wear because of the roar from the tires.

There can be big differences-

also, had to wait two weeks once for replacement tire beacause the seller had none in stock--
had to fo elsewhere to get tires sonce 2 were damaged beyond repair in one week.
Yes, PA potholes are prolfic and deep.

 

Discount tire for life guys.....second to none.

 

May worth noting that if you get them at the dealer, they are considered original MB parts and come with a one year unlimited mile warranty that, as I was told by a former MB master tech, covers punctures, bubbles, etc. You may want to confirm but if this is the case it beats the Tire Rack road hazard coverage which has a deductible and does not cover the mounting, balancing and disposal of the old time.
Also, as I have proclaimed repeatedly in many threads, I strongly recommend Continental DSW06 over anything else - dont know if they would stagger well though.

 

Call dealer and ask them for better price before coupion..

I did and got tires for less then local wal-mart.

 

We love Discount Tires too. 3 blocks away, great service, great pricing too since they've always matched best competitors' prices. If they don't have 'em in stock, it'll be next day.

 

I believe Costco's road hazard is 5 years. Not sure what their flat warranty is, thought it was free flat repair. Some people complain about the wait at Costco but if you make an appointment, it's not too bad, in and out in about an hour or less.
