The guys mounting them struggled a little with the oem sport rays but they got perfectly. I think I posted pics a few pages back

I dont have sport rays.... I have TE.6 wheels

Should rename this thread "Tiny Tires". :icon14:

Haha we all can roll 12" wide wheels like you.

I got 305s on oem wheels so suck it ;)

Also get your *** up here for a meet soon lol

:rofl2: Maybe some day you'll be with the "Wide Rollers". :D

I'm trying, believe me. Going on vacation next week. Going to Colorado Springs, then to Moab, then to Lake Powell Ut, then to Denver, then to Cheyenne Wy, then to Black Hills SD, then home on the 19th. Unless I get a bug up my a$$ and say screw it with work and e-mail them my retirement request. Doing a trackday at Pitt Race on 7/25 for sure. :driving: Trying to work my schedule so that I can get more time for Z things. :driving:

Maybe ill just have to go to the track to see it lol that track is only like 20 min from my house.

normally youd be right but in this case since the entire 1.5 inches was added to the back you do not divide anything by half because the whole additionaly 38.1mm was added all on the backside none on the front, and its only 45 not 48 because you lose 1/16th of an inch when they make the seperation cut

Nope. I'm 100% correct. I've widened wheels before. You're correct about the 1/16th part (or 1.5mm). So actually his offset is closer to +30 than +29.

1010TIRES.COM - Wheel Offset Calculator

Plug in 11 wide and +10 offset on the top
Plug in 12.5 wide and +29 on the bottom

Then try it with your numbers.

Let me know what you figured out.

;)

Being right hurts...

I stand corrected

This kind of stuff drives me nuts. The OP listed offsets that were completely wrong because they didn't know how to calculate the final offsets once the wheels were widened. Now people reading through this thread will come across that post and order wheels in that exact offset. When they get them and put them on, they will realize that the thousands of dollars they spent on their wheels went down the drain. Not cool in my opinion.

What the mods should do is go and edit his post for future members.

Bottom line is that if you don't know what your talking about or don't understand offsets, please don't post.

Michelin Tires
 

Anybody try the more expensive Pilot Sport PS2 vs
the less expensive Pilot Super Sports.

i will be going with my stock rays
Seems that Tire Rack surveys like the cheaper Pilot Super Sports
front 265/35/19
back 305/30/19

Thanks

PSS replaces PS2.

super sports blow the ps2's away. just FYI.

40th Anniversary stock rims... S04 Pole Positions 305/30R19s

Rays gramlights 19x9.5 +35 19x10.5 +25 p265/35r19 p305/30r19

Wanting to keep my original 40th rims, I also went to 265/35/19 Front and 305/30/19 Rear. Hankook EVO2's for me.

Tire fitment question?

Wheel width range for a 285/30/20 is 9.5" - 10.5"

Am I going to run into any problems putting a 285/30/20 on an 11" wide rim? If so, what concerns will there be?

I need all season tires and 285/30/20 is as big of an All Season Tire that I can find.

Thanks

Ok so I did go back and edit my posts to show the corrected offset, and it's not like I'm a retard drooling on myself, I made a simple oversight when figuring the end result but obviously I do know a little because my physical measurements are spot on or else I would've been the guy whose money went down the drain, so please, next time try just saying "Hey, could you go back and edit your posts so there's no confusion for future members ordering wheel sizes" instead of attacking my character and intelligence.
thanks, from a diplomatic pacifist car enthusiast.

I'm not attacking your character. I was making a general statement and wasn't intended strictly for you. Sorry you took it that way.

Its all coming together now. The following is wheel porn and should be viewed with caution:

Who likes meat? I do!! How about some 325's on the rear:

As you can see the fitment is spot on. Took me a while to get these offset just right. The wheel sizes are 20x9.5" front with a 265 and 20x12" rear with a 325. Both tires are Michelin Pilot Super Sports.

R.K.

What offsets are you running?

+20 front and +26 rear. The rear has -1.9 degree's camber.

R.K.

Do you guys know the stock camber measurements for front and rear?

looks awesome dude!!! you have to drop the car and you are done :tup:

Look out for aquaplaning.

Quick stupid question(s)... :icon14:

When you guys say 19x11 +22, the "+22" is the offset of the wheel, correct? But then I see some people say they use spacers as well. I thought buying a custom wheel with a custom offset removed the need for spacers?

If stock rear is 19x10 +30 then a wheel that is 19x10 +10 with a 20mm spacer would be the same, correct?

So you either run stock 19x10 +30 and 20mm spacer to get a final offset of 19x10 +10 to be close to flush, or for example: buy a aftermarket wheel that 19x11 +20 which will give you almost the same result as running a 22.7mm spacer. Yes no maybe so?

Thanks for the help in advance!

See my answers in BOLD.

radride what sidewall size is that 325?

325/30-19 PSS's ?

25 Series

325/25/20. My wheels are 20's. I could of easily went 335 or even 345 but decided against that.

R.K.

Damn, you fooled me. ;)

What's your offsets if you don't mind sharing, also 325/25/20 -- 265/30/20 ?

+20 front and +26 rear.

R.K.

Thx...repped

Has anyone been able to fit a 325/30/19 on a stock Nismo 10.5" wheel?? I bought a used set of Goodyear Eagle F1 Supercar EMTs and nobody could seat the beads. I really want a 325 tire for looks and because it's the only size up from the factory 285/35/19 that is pretty much the exact same diameter.

I bought the used set of Goodyears for that reason, to test fit....but they wouldn't fit and I believe it's mainly because they are run flats and the sidewall is mutch thicker...and in combination with the extra width, it causes an issue. I am wondering if anybody has been able to fit a regular 325/30/19 tire on the factory Nismo rim.

The car that comes with these from the factory is the C6 Corvette Z06 / Grand Sport, which has 19x12" wheels in the rear...I figured that 1.5" less than a factory spec size would still work but apparently I was wrong. I just hope that someone has been able to fit a normal 325.

Thanx

305/30 is close enough!!! And it looks good
