I only know about a slight bulge with RS3s. I haven't really seen it in person.

My 305 RS3s on the Nismo wheels without a spacer on stock ride height looks amazing

Thing is, I can get a pair of RS3-S 325/30/19s for $368 shipped (atleast right now), 305/30/19s I won't be able to get for much under $500...plus I really want to try 325s...looks like noone's done it so I'll post pics when I do :)

305s look good on the 10" wide rays, that's why I want 315 or 325 on the 10.5" rays

I'm concerned about the height of the sidewalls of 325/30 being too high

Might look funny....

Well it's the same height as the sidewall on the original 285/35/19. A tire size calculator can confirm the diameter is 4mm less on the 325 vs the 285, that's a 0.6% difference, so that means that the sidewall on the 325/30/19 is actually 2mm (0.3%) lower than the one on the original 285/35/19...that's if tires are made with that kind of acuracy...which they are not since we all know that 2 "same size" tires from 2 different manufacturers can have quite a difference, however, the tire size calculator can give you a relative idea of tire size differences.

The RE11's, while not a runflat, do have a stiffer sidewall than most tires. My friend and I were both running 305/30's on the sport rays, he had ps2's i believe and i have re11's, his did bulge and mine had no bulge. The minimum side recommended for a 305 tire is a 10.5 inch wheel. So the .5 isnt too far of a stretch to make it fit. There is no way in the world I would attempt anything bigger on my wheel though. Even if someone could mount it... that being said the same goes for the 325 on a 10.5 inch wheel. Trying to get it on a wheel thats an inch narrower than the minimum recommended size... I wouldnt chance it OP, it could become a big safety issue just my .02 though. The 305 looks great on the nismo wheels IMO

We are also not taking into account for a buged/stretched sidewall vs one that is straight (flush) with the wheel. Technically, the straighter (flusher) the sidewall is, the taller it would be, so a 325/30/19 should have an overall lower profile sidewall on that wheel than the original 285/35/19 that is almost flush.

I really don't understand your obsession with 325s but I am curious to see the result :)

In for pics!

I understand what you're saying, but I want to see the look the 325s will give the car. I went to Discount Tire again today and ordered a pair of rs3s 325/30/19. The manager looked it up by car in the system for both the sport package and nismo, and to my surprise, 325/30/19s were an optional size for both. He said he's positive they'll fit because if it's in their system then it would definately work because they use it everyday and blah blah blah...but nevertheless, if they end up not fitting I can just get my money back and buy 305s :)

You do realize that you are in the "370z MEATY TIRE THREAD" right? Haha

Will post pics sometime next week hopefully :)

Btw, my 285/35/19s from the rear are going in the front ;)

I'm sure those would fit fine on the 9.5s, plus the tires have camber wear from being in the reat and my Z has no front camber wear so it should work just fine..for a while

If you want to see what 325's look like. Look at my Z. Next week will be 345's. :D

Post some pics :)

It's still gonna be different though, because I'm putting the 325s on the stock nismo 10.5" wheels, which would give the 325 quite a bulge I beleive

Rusty, you're an animal! :tiphat:

So I guess 345s give you "Animal" status in the meaty tire thread :tup: haha

Rodger that...
