how wide are the factory 17's on the 5th gen? and has anyone put 235's on them?

 

 

that's what I was afraid of, that means no 235's for me.

 

Dany said he saw somone at the dealer with 235z, they'll fit but not sure how reliable that is.

 

IMHO

 

rims. And they looked very good. Meaning, I didn't see that the tire was buldging out on the rim and stuff.
When I looked from the back on that car, the tires didn't look any wider than mine 225/50 stock size.

 

I think there were a few people on the board that does have 235. I think 235/45/17 and 225/50/17 is not a very big difference in size.

 

no it's not a big difference, 10mm I think. but I'd be weary of that being the straw that breaks the camels back and having my tires pop off the rim in a hard corner or something, could you imagine!

 

Ugly sight!

I did the wheel thing (from the Miata thing) and 225/50/17 was quite a bit off from 235/45/17 (speedometer-wise).

 

I actually have 235/45ZR17 on mine with 17x7. Doesn't protrude at all, what do u think? (Sorry for the size of the jpeg)

 

[I}Looks like they fit fine on there.

 

you have 17x7.0" wheels? Almost all 17" wheels are 7.5" in width - the standard Maxima SE 17x7.0"s are a fairly atypical size.

 

Guys,

The main concern is not about looks... it's two things... one your contact pact is reduced b/c the tire has to buldge to fit onto the rim, kinda defeats the purpose of going with wider tires... and second which is the most important of the two is that the rim may not suppor the tire probably. There will be too much sidewall bending and buldging, more than it was intended and designed for. You should REALLY try and get the rim width that's ideal for the tires. You can check the tire manufacturer site for this information. I'll tell you right now, that for most 234.45.17 you will need atleast 7.5.

All,
Just thought I'd chime in here with some info and looking for advice:

-Tire manufacturers do state the min to max rim size needed for their tires.
-That said, most 235/45-17 tire choices I've seen require
a min of 7.5" rim.

-However, the Pirelli P7000 Super Sport in size
245/45-17 has a min rim size of 7.0"

If you compare the stock 225/50-17 to 235/45-17 & 245/45-17 as far as the actual diameters go it goes something like this:

The calculation = (Width X Aspect Ratio) X 2 + Wheel Diameter = Overall wheel/tire diameter

225/50-17 = 225*(.50)*2 + 431.8mm = 656.8mm / 25.4 = 25.86"
235/45-17 = 235*(.45)*2 + 431.8mm = 643.3mm / 25.4 = 25.33"
245/45-17 = 245*(.45)*2 + 431.8mm = 652.3mm / 25.4 = 25.68"

If you want to keep the stock SE rims and would like a higher performance tire then the Pirelli P7000 Super Sport in 245/45-17 will fit on a 7.0" rim (unless Pirelli's
datasheet is in error) and be closer to stock overall diameter that the 235/45-17.

Of course if you buy new 17" or 18" rims you have a multitude of choices. Just make sure the overall diameter calculation is not too different than the stock overall diameter of 25.86" and your speedo will be fairly close.

Anyone have any experience with the Pirelli P7000's?? Tirerack.com rated them very highly in their testing...
