Does anyone know the offset for the 350Z 17" rims are?? I have heard they are 30mm for the front and 33mm for the rear.. with rims size of 17x7.5 (front) and 17x8 (rear).. is all this info correct?? Thanks in advance..

Thats correct. I have the 17's on my 97 SE right now. BTW when it comes time to rotate them I am still going to do them the normal way. fr to bk.

It may look weird, do you have the same size tires all around on them?

Maxgig

iTrader: (5)

Yes, I'm running 235/45/17's. I wanted to go with 50's on the back but the tirerack guy said they might rub on turns if I rotatated them from front to back, like I intend to. I also have a gap which I might fix by lowering.

I hated that gap, but with the ksports, no more problems

The 17" Z wheels look sweet on the 4th gens but I didn't go with them because of the fact that the rears where a different tire size than the fronts. I ended up getting the stock SE rims instead for my GXE. You lose the ability to rotate your tires with the Z wheels unless you want your car to look funny.

I just put the same size all around. If you did put bigger tires on the rear you could just rotate left to right which would give you the same effect as going from fr to bk.

yea...the 350z rims are great. Except i have noticed a dip in my MPG and my acceleration is a little slower. Gives the car a nice look. Plus my car is pretty much stock

iTrader: (1)

i too have noticed the huge loss in MPG. the car still moves though. did you weigh them by any chance before you put em on? i didnt but i think i might take one off and see how much the difference is between them and my stocks

Resize your sig your now. That things way to big....what were you thinking.

You have to re-calculate your miles traveled as having those rims on there compared to the stock rims changes alot of things, the odo and speedo are both off right now.

The reason not to rotate radial cord tires left to right is due to the radial cords take a set in the direction of rotation. If they are mounted in the other direction, failure in the cord may occur.

When tires used bias cords, they were placed in opposing direction to counter the rotational set and you could mount those left to right.

Are you using the original lug nuts with these wheels? since I put them on it feels like there is something lose in the front end and I went through the tires very fast. Also I have 235/50/17 in the back and they don't rub.

Here is a sizing chart for different tires and wheel combinations. The top line is the standard size for my '98 I30. Size with the arrow is on my 2nd set of wheels from a 2000 I30. The percent column to the right are the speedo variation. The sizes shown are not checked for fit, just for diameter:

Width Aspect Whl Tire
------ Ratio Dia Dai
mm percent inch mm inch
Standard
205 65 15 647.5 25.49

225 60 15 651.0 1% 25.62
245 55 15 650.5 0% 25.61
205 60 16 652.4 1% 25.68
215 55 16 642.9 -1% 25.31<<
195 55 17 646.3 0% 25.44
215 50 17 646.8 0% 25.46
235 45 17 643.3 -1% 25.33

Since speedo is on the front for A32/A33 cars, rear tires don't affect speedo. However, they will confuse the ABS controller and it will come on more frequently.

arrrghhh

i don't mean to get off-topic, but how much would it cost to have the odo/spedo recalibrated? is it reasonable or just not worth it? thanks.

SVI30

A 2% oversize is just 1MPH more at 50MPH. So it is not a big deal. I have a 4% over size on my Suburban right now. Which will be 2MPH over at 50MPH.

That 235/50/17 dastry running is 3% over size but he has it on the rear, which doesn't affect speedo.

arrrghhh

iTrader: (2)

well that's good to know... speedos aren't that accurate to begin with. how badly does it affect odo mileage in the long-run?

SVI30

Big wheels rob torgue due to the weight moving to the outer edge. The dip in gas mileage probably comes from wider tire.

dastry

what about lug nuts? are you using the maxima stock or the ones of the Z? Just making sure the problems I'm having in the front end are not related to them.

SVI30

The ODO will be reduced about the same amount.

The 350Z tires are nice, but what do they weight compared to our stock. Also how about the NISMO rims the 17 or 18's? I wonder what they will look like on our cars. (any one with photoshop: can you please try)

how do you know the % on how big your tires got?

SVI30

If the wheel is tight at mounting then it should not be a nut issue. It may be a wheel offset issue.

The suspension and steering forces are designed for the original offset, which is inboard for a FWD. Moving the wheel offset to RWD type essentially moves the wheel outboard, which increases the force on the spring, shock and steering mechanism as the wheel moves up and down. This is because the wheel will be further from the pivot point than originally designed.

SVI30

I made a tire/wheel size calculator using MS Excel spreadsheet. Here is the formula for calculation diameter:

Diameter=2x(tire width x aspect ratio/100)+(wheel dia x 25.4)
Note: divide by 100 to get the percentage back to fractional. 25.4 is the conversion factor from inch to mm.

The circumference is diameter x PI. PI is a constant so comparing diameter is ok.

Once the original diameter is obtained as a baseline number, then oversize is calculated from it.

oversize % = (oversize dia- std dia) / std dia x 100

SVI30

So a set of FWD wheels from a 5th gen A33 Maxima will be preferred to a set of wheels from a RWD Z.

Don't mean to thread jack but I was recently able to purchase a set of these wheels however opted to go with the 17x8 all around. Thinking about going with 245/45/17 tires, do you guys think I'll have any problems with that setup?

SVI30

Diameter wise it is only 1% oversize. The width may be too much for the front so you have to check the fit.

dastry,
Yes I am using my lugs from my Maxima. In fact I broke a stud and had to replace it. Just make sure you use acorn style lugs. (Rounded off on the bottom)
