I went to a tire shop down the street from my office and found a set of hardly used Pirelli PZero Rosso in 225/45/17s. The guy I talked to was quite knowledgeable and said that they would fit on my Max. I've done the search thing but I'd like to get a definitive answer here.
What do you guys think?

 

thats great, but what size is the rim?

 

if the rim is 17 X 7, 17 X 7.5 or 17 X 8 it should be just fine.

Overall diameter is closer to stock with 45 profile tires on 4th gens.

 

Well the guy suggested the 17x8 5Zigen 5ZR Copse in black chrome would be good for the black Max. I think I'll go back after work tomorrow to test fit them and see if I like how they look on the Max.

 

That should be a great combo of rims and tires...I have the 235/45/17 Kumhos and they are wide...may help in the turns but your mileage per gallon will be better than mine with a bit more narrow tire...I am sure there is no problem with it and you will enjoy them...gee I sound like a tire salesman...wait I am a tire salesman...

 

. . .to retain speedo/odo accuracy and highway fuel economy, but a 225 isn't too far off if the price is really "right" on these tires.

With the 225,

-your highway fuel economy may suffer a little bit (not much)
-your speedometer will be slightly off: it will indicate you're going slightly faster than you really are
-your odometer will collect a few more miles over the life of the tires than with a comparable 235/45/17 tire.

On the plus side though, your gearing will effectively be a tiny bit shorter as a result of the smaller tire, which can yield slightly faster launches/0-60 times.

Hope this helps!

P.S: The other thing to think about is that the Maxima already has a cavernous wheelwell. You never really want to do anything that accentuates this or calls greater attention to it. It may not seem like a big difference between a 225 & 235, but it's just one of those things - you might want to have a look at the two sized tires against your wheelwell just to get an idea if it's going to bug you or not. If you're not already lowered or not planning on being, I'd seriously consider getting a larger tire. B4 I lowered my Max, I test-fitted my 17" wheels mounted w/ 235/45/17's, took one look at it & said - oh no, that won't do at all. . . MAAAAAD wheel gap. Even w/ the 235, because of the look, my stock suspension had to go. -Just something to keep in mind.

 

I had 245/45/17 on my MHT Quans before I dropped the car. Once I put the 1-1/2" drop springs on, the fit was tight at the top (two finger maximum). Since then, I went to 225/45/17 Michelin's and it looks better and there is no possiblilty of scrubbing... btw... I got the Michelin's off a 2001 BMW 7 series with 15,000 miles on them... all four tires mounted and ballanced for $50.00.... it is good to have friends in the right places...

 

I have 225/45-17s on my 17X7 rims. I went with the size because they wouldn't warranty anything bigger than 225 on a 7" rim. They work well, perform well, but they do make wheelgap look larger than normal.

 

Thanks for your responses, guys!
I'm still going to check around and get another price on the Pirellis and compare how good of a discount it is. I wasn't too keen at first on the Copse in the ads but seeing it in person it looks pretty darn good. $299 Cdn a rim while the Pirellis are going for $250 Cdn.
I'm on Eibachs now so I hope the wheel gap isn't obvious!
