On my 2011 G37X, I'm planning to get new tires next week...

Does my car come with TPMS sensors? If I change my tires on all 4 wheels, would I need to get new TPMS kit? (I'm keeping stock 17'' wheels)

I didnt even know my car had TPMS, but Tirerack said it does. I'm not sure.

I do know it has a low tire pressure warning...

 

No dude you can use your factory tpms.. just tell the tire shop to use the factory ones thats on the 17''s.

 

All cars from 2007 and newer has TPMS. You should check out the owners manual. All kind of good info in there.

 

When I priced out new tires the dealer was close in price to tire shops.

I went with Michelin Pilot AS3's

I went with the dealer because if a tire shop screws up your TPMS sensors you may end up having to make a trip to the dealer anyway.
Each wheel TPMS needs to be correctly paired to the vehicle and I doubt if tire shops can do that.
The dealer also washed and vacuumed my car.
Very happy with the new tires that perform well on ice and hard snow packed roads.

Everything you posted was great except letting the dealer wash your car, I've only had one courtesy wash and it was a scratch & swirl-fest. Car had to be machine polished after that one, I always specifically tell them to keep my car dirty thank you very much

 

Without a doubt something I stopped doing when I had my VW Jetta last year. I kept that car in PERFECT condition and my first trip to the dealer left me with a terrible wash job and a white car covered with swirls.

 

My dealership knows how **** I am about my car so they change the sponges per my request. Good friend of mine there says "think about the two sponges we use...times a good 20-30cars washed... With the same sponges...only thrown out when they're ripped or torn"
Aka swirlnation.

 

Agreed. Never, ever let the dealership wash your car. That's just careless car ownership, unless you're actually watching them do it. In which case, just freaking do it yourself.

You know, it's not the first time 87 Octane has mentioned how awesome it is that the dealership washes his car, and it won't be the last. It's funny how things that are actually detrimental overall are perceived as something of value by people predisposed to be True Believers. You can't fix it, Brad, so all you can do is correct bad advice when it happens.

 

Tires are a pia. Yours came with TPMS. I assume you're not doing a winter changeover but just replacing tires, so I would go with keeping the same TPMS and switching them over to the new tires. As for the dealer washing your car.. Its hit or miss. It depends on the dealer. Imagine a dealer that swirled every new car on their lot? Would you buy a car there? As a general rule you can avoid the risk, but I personally have never had a bad dealer wash with swirls at Infiniti or prior BMW. I know I wont get popularity votes, but the dealer wont smack your rims around as much as other shops. But it'll cost you more.

 

Took your advise and skipped the dealer last weekend.

Shortly after filling up with a tank of regular

The local high school was washing cars $5.00 so i finally got rid of all the road salt since the last wash at the dealer in January.

My dealer has always washed my car, and I’ve never had a problem with it. The car comes out perfectly clean with no scratches, etc. Perhaps your particular dealer is the problem.

 

^Depends. My particular dealership knows me, so they use new sponges, legitimately gives her a wax, etc. Yet the other cars just get the quick spray, soap and rinse with recycled sponges which carry over all those minerals and salts from all of the other cars they wash, onto yours. Hence the swirl job...

 

Uncle.

Could be. It's also possible we have different standards.

 

I'm on my second Infiniti and have never had a problem with the dealer either.

Right on with you brother...sadly my second day of owning my car my brother decides to "buy me a car wash" right after a winter storm....
When you're basically Mr. Swirly might as well go to the dealership for free LOL

On the other hand, just made my appointment for a full detail in a month. Pics to come
