I had the steering rack replaced under warranty and it reduced the slack. I also put on Conti Contacts; about $750.00 installed at Mavis Tire. Lease is up 1/2009 so Michelins would be an extravagance. I am very happy with the steering and tracking now. Much more tread depth for snow on an occasional ski trip. I might lease another one or the new FX if the improve the mileage with the 7-speed. My dog would prefer it. The FX on the Infiniti europe web site touts weight savings on the new FX. Aluminum bonnet (hood) and plastic tailgate among others.

Tire pressure for Eagle F-1's by alanpreston05

I just replaced the OEM RSA's on my '06 M35x at 43,000 miles, with Eagle F-1's. What a difference. Surprisingly, the Infiniti dealer's price was right in line with several local tire specialty places, so I went with them. My question is this: What's the appropriate pressure for the F-1's? After installation, the dealer set the (nitrogen) pressure to 42 psi. I thought that seemed incredibly high, but the ride and handling were great.
 
I took the car back for some minor service a few weeks later and mentioned the tire pressure - and when I picked up the car they had lowered the pressure to 34 psi. The ride and handling are also excellent at this pressure; but I am wondering, what's correct and why did they put them at 42 first and now down to 34 What's the right pressure?

My '06 M35x drove horrible and I always attributed it to the RSA's so when I replaced them with Bridgestone RE960s and it wasn't any better I was frustrated. Enter the '08 and my preference for the early body so I traded my early '06 on a late '07 to keep me in this body until a newer car comes out ... anyway the problem disappeared with the new car even though I was back on RSAs again.
 
Now, was it that the newer rack (I assume the '07 has been "fixed") was already on this car or the fact the tire were inflated to 40 PSI when I got it? I don't know, but I've kept the inflation up an have no outer-edge tire wear like I used to and it drive much better. I'd say if the ride comfort does not bother you, keep the pressure up and monitor the tires for excessive wear in the center from too much pressure.
 
What REALLY bothers me is the tire pressure monitors read 3 lbs. low across the board!!!

2007 m35 Tires Good Year Rsa by bgiannantonio

These tires are terrible as after 15000 miles they were worn to just about the tire wear bars. The tires were rotated at 7000 miles and 14000 miles with the tire preassure at 34-35 lbs the allignment was checked and was correct. The car was terrible as well as not safe in the rain. The car would wander all over the highway following the groves of the road I had contacted Infiniti as well as my dealer after reading all these other unhappy customers of this vechile to no get no help. I was very suprised at ther response for this high priced high end vechicle. After no responce from the dealer or Infiniti I went out and spent over $1200 on new Michlien Primacy's after about 600 miles car rides as new tracks straight as well as rides like a $50K vechicle not like a homemade go cart Very suprised this issue has not been adressed By Infiniti

You can file a complaint with the US Dept. of Transportation. Maybe a class action lawyer would be interested.

Just replaced my Goodyear RSA's 19,000 miles with Goodyear Eagle F1's. No more sliding in the rain & corners great.

I, too, have followed the recommended rotating, tire pressure, etc. for the RSA's, but have extensive wear, and a sidewall bubble with less than 20,000 miles on them. I am 90 days away from turning in my lease, and I'm afraid I am going to have to replace these tires at my own expense. This just burns me up, since prior to accepting the lease, I was told by the dealer that there is no reason I should have to replace tires with a 21 month lease, which I specifically asked about. But I suppose they will tell you anything to get you to buy their product. Has ANYONE ever gotten a reply from Infiniti as to why they are using an inferior product on an otherwise superior vehicle??

I would call Goodyear and threaten to file a complaint with the Federal government NHTSA. Also call Consumer's org in Mt.Vernon NY. And the talk show Michael Savage who is starting a national campaign because he had to replace 2-tires in a year on his new Mercedes. Post complains on tirerack.com. Send Goodyear copies of all the complaints on this board and send copies to your Congressman. Sue in Small Claims Court.

I've never bought a new car that had decent tires on it. Spanning a 28 year period I, or my wife, have owned 4 SAABS, 3 Volvos, 2 BMWs, 4 Audis, 1 Acura and now on 3rd Infiniti. The tires have always been at the bottom of the list in their class (check tirerack), but not necessarily "cheap" tires. You can buy a much better tire for the same cost as an RS-A, but crumby Continental, Michelin, Goodrich or Goodyear have been on cars that deserve much better tires. Given the cost of these cars, and the fact that tires contribute so much to the quality of the ride, one would think the manufactures would be putting better rubber on them, but I guess they save a few bucks per and it all adds to the bottom line.
