Infiniti M35/M45 Tires

    06 M35 Would like new tires. Have 44k on RS-A. Want something with less road noise and fun to drive. What is the answer?

    Michelin Primacy MXV4, I have 15k miles on them and they are great in all kinds of weather. I live in the upper mid-west and drive through a lot of snow and rain. Quiet, no flat spots, handle great in all types of weather and on all surfaces. $1100 at the Infiniti dealer, including alignment and 2 year road hazard warranty. I could have saved a $100 bucks at the tire store but I wasnt comfortable with their ability to deal with any TPMS problems that might occur, even the dealer had a problem with one wheel.

    Good luck. Mine is a 2006 M35X.

    For anyone who cares, I have now had General Exclaim UHP tires of my M35 for 7 months and 9k miles. Wear and tear is minimal, handling in wet/dry is great and ride is very nice. For anyone looking for an amazing bargain, look no further. They are also the highest rated performance tires on Tire Rack.

    The dealer installed the Yokohama tires and I'm shocked at the difference they have made!! :D 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.

    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!

    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'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....

    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.
  • Has anyone tried 245/45x19 tires instead of the 245/40x19 tires that come as original equipment on a M35 sport?
  • james27james27 Posts: 433
    The higher profile tile would be close to 1" larger in diameter, and throw the speedo off by about 1%. If you have the nav system, it should autocalibrate. That extra inch may mean the tire will rub when turning or if you hit a large bump. This could poke a hole in the tire.
  • This Place

    Has 4 ContiExtremeContact for under $500 and cheap shipping does anyone know if this is a good deal and if these are as good as the original tires?

    I have them on my 2006 M35X. Much better ride & traction in the wet. Sounds cheap. Add in freight, tax, mounting and balancing. Go to local tire store and show them the on-line price and see what deal they will cut. Make sure you don't lose the wheel lock key like I did.
  • I am considering getting an M35 RWD and I wonder how bad it will be to drive it in Michigan winter?
    Anyone care to share their experience driving M35 RWD in semi-harsh winter conditions (Midwest, not Alaska) ?
    Do winter tires make it better to the point of being managable?
    TIA !

    I have driven both a miata and a BMW 3 series during snowy winters commuting about 30 min each way in Connecticut. Both cars are reputed to be poor in the snow and ice. I never had a problem....but the key is to put four good snow tires on the car...not 2, not studded, not heavily worn and built to grip in the snow/ice with soft rubber. At the time I used Blizzaks. Of course you have to be careful not to spin the wheels and keep your speed even.

    Of course 4wd cars are better in the snow......however, I have also driven Jeep Cherokees and Grand Cherokees to/from Vt and it's the only car that I lost control in on an fact there were a few days with black ice that many jeeps spun out...I was far from alone. Nothing helps in black ice...and actually a 4wd car is more likely to spin out because you are over confident. In heavy snow, a Jeep is just wonderful....

    My view is that 4 good new winter tires make any car manageable in the snow.

    All-season tires are a compromise all seasons. Good snow tires can make a huge difference in traction not only when the roads are nasty but anytime the temperature drops below 40-degrees F. All-wheel drive can help you get started and maybe grab some traction in a turn, but nothing beats the laws of gravity. Stopping would be the same, regardless of the number of driven wheels (with the exception that the 4-wheel version is a little heavier).

    Apparantly on the 2009, the M35 gets the new transmission and engine; the M35x gets the engine, but keeps the old 5-speed.
