The dealer installed the Yokohama tires and I'm shocked at the difference they have made!! The ride is silky smooth and the noise is dramatically reduced. I'm not sure how the tires will perform in rain or snow, but I'll update once I've driven in those conditions. I am so happy that this worked out.

Mismatch Tire Brands by oz44

Hello all,
 
I was hoping someone could help me out with which way I should proceed. I recently bought a Certified 07 M35x that came off of a 2yr lease. I've had the car for about a week now. I just noticed that there are two different pairs of tires on the car. The two front wheels have the Goodyear RS-A's on them and the back two wheels have Hankook Ventus V4's on them. They're all 245-45-18 though. All four tires have fairly good tread left on them.
 
Do I have any ground to ask the dealer to give me a complete matching set or offer some type of discount for a new set? Or am I screwed for not noticing the difference before I bought the car.
If the dealer won't do anything about the tire brand difference should I keep them. The ride isn't the greatest as far as road noise and vibration. I'm comparing this to the ride of the G35x that they gave me while my car was being serviced.
 
Thanks for the advice!
Chris

Read the owner's manual...I'm pretty sure that it states ALL tires must be the same brand and type. This is more important on the all-wheel drive versions than rear-wheel only, but can be a safety issue on either as it will alter the front/rear grip and braking. Also, there is a spec about the real diameter...it's pretty tight, I think like 1/8", and you may not have that with different brands, or even different models from the same company. That's why on all-wheel drive cars, it becomes expensive, as you often need to replace all four tires when you have a problem with one.

If you bought this car from an Infiniti dealer and if it is certified then definitely go back and get four of the same tires. ABS systems can be dangerous if you don't have the same tires on all four wheels.
 
Push the dealer to give you four of the same tires.......a certified car should meet the manufacturers requirements as stated in the owners manual....
 
If they won't do it, escalate to Infiniti. Tell them that they are liable if there is any problem/accident caused by tires that don't match. Someone will give....

Thanks! I just looked at the manual and you're right. I will use this info when I talk to the dealer.

Hi Chris. Sounds like the Leasee or dealer replaced 2 of the original Goodyear tires. You could ask the dealer about matching them somehow but they may reply you missed it before buying. At least they are the same size. You could check with a discount tire dealer about getting a new set of 4 with some money off for your current tires. I got 4 Contiprocontacts installed for under $600 and really like them. Now there is a General all season tire rated best in category (245-45-18) and probably well priced. Check with a mechanic you trust. Good luck.

you missed "certified" used car. I don't think the dealer has a leg to stand on...he fundamentally sold a car that does not meet the manufacturers requirements.
 
While you have to be pleasant, I think that being firm will get a set of matching tires. You might even be able to sneak it in under the used car warranty and get the tires replaced. They could just swap them with another used car on the lot.
 
If not, I would personally buy two new matching tires and take the dealer to small claims court. It will not play well when you show 1) the car was a "certified" used car; 2) It was purchased from an Infiniti dealer; 3) the owners manual says that the tires must be the same; 4) the car has mismatched tires. The dealer will hide behind the fact that certified doesn't address anything other than tire depth...but I suspect I would win based on the sheer simplicity of the logic.
 
Now if there was an accident where the tires came into play, the lawyers would just have a field day with this one....

Replacement Tires - M35x by c5_4fun

I need to replace the RSAs on my M35x. I've seen many advertised replacement tires (ContiExtremeContact, Michelin Primacy, Potenza RE960, Yokahama Advan S.$ and Avid W4S, Eagle GT's and on and on). I won't put RSAs back on the car, but would like to get opinions from others who've put different tires on your M35 and what you like/dislike. I am in the midwest, so I'm in wet, dry and a little snow, and drive the highway at higher speeds 50% of the time.

2006 M35x. Last winter I replaced the RSA's with Conti Contacts. The car rides much better. Traction in snow and rain is more confident. The steering is not as precise as the RSA's. My decision was based more upon price. My 3-year lease expires in January. I drive in suburban NY City mostly. I rarely exceed 70 m.p.h. I have gone to VT and been satisfied in the snow. If I owned the car I may have bought more expensive Michelins. If I skied allot I would buy winter tires.

The ContiExtremeContacts have been great on my M35X for 12k miles. Much better than OEM Goodyears. Best part, tires installed were under $600 in NH.
