What size did they replace your front tires with? I finally got my tires replaced because of the tire growl problem. When I got home I decided to see if I can see any difference with the new tires. They are Bridgestone Potenzas RE040's but the size is 245/45/18. Is that what everyone else received as replacements? I dont understand why Nissan would put wider tires up front than what are suppose to come from the factory. For some reason I think the stealership messed up!

 

thats not right...........

 

thats the size for rear tires.. I think they sent you the wrong tires, check with your dealer

 

i heard it was because they put too skinny of tires on there in the first place to match the suspension... this came from a guy who used to work at nissan and now a tire place. but who knows

 

oh, and mine they put 45's on the front too

 

Same happened to me too.
It drives fine.
I've heard its actualy a better to have have all 4 tires same size on the Z.

 

So I guess that is the way it is suppose to be then. I just figured they would keep them the original 225's, because by reading the letter the said they had special or a new type of tire made for this problem. Well RE040's have been around for a while now. I guess it was Nissan just blowing smoke up everyone's ***.

 

So are the front and rear rims the same? If they are I guess I can now rotate my tires.

 

I got new front tires re the TSB. I just went to check and it says 225/45/18. You guys who got the 245's in the front... I can only think of 3 scenerios.

1. Your dealership is stupid and installed the old style rear tires in the front rims.
2. You guys already had 245 to begin with and they had to replace the number that you have.
3. I got screwed and got the 225 when I should have gotton the 245's like you guys did

 

Well I had stock tires on the car to begin with so your #2 is out the door. I guess we should contact Nissan USA to find out what size should have been used. It certainly doesn't make sense to supposedly find a solution for the problem and blame the original tires and then start putting one size tires on one car and another size tire on an another. There is a screw up somewhere.

 

Just got 225/45 put on the front of mine.

 

Damn I wish I had known you had the tire growl. I have been wanting to hear it forever to see what everyone is always complaining about.

 

have any of you been able to get new tires with suspension work?

 

You gotta be sh*tting me. It's gotta be the most annoying thing on my car. I cant imagine how quiet this car is going to sound after I get new tires on. The difference will be like closing the door on a new Lexus vs closing the door on an 84 camaro.

 

Yeah there is a huge difference now. I forgot how quiet the car was when coming to a stop or driving below 25 m.p.h. lol

 

performance models have 18x8 all around
track 18x8.0 front, 18x8.5 rear
base 17x7.5 and 17x8.0

 

Mike, are you positive about the Performance/Touring's having 18x8 all around?? If so, I'm gonna be so happy cause I've been wanting to run a 245 all around setup sooo bad, but I thought I'd need to buy different rims.

If this is the case, why do the front wheel hubs have that 6th "bolt" to prevent rotating front to back? If the rims were the same, the 6th bolt would be useless.. correct?

 

The wheels are the same size front to back on the OEM 18" non track wheels, but the OEM tires are not which is why they still put the bolt to stop Nissan's idiot techs.
