Hi guys i just had a question. im about to buy some IFORGED wheels off ebay but the sizes are 8.5 in front and 12 in the back.i know the fron is fine but i was wondering if the back is too wide.thanks for any help

 

also what how wide of a tire would i have to put on the wheels if they do work.
P.S they're 19"

 

You can get away with a 12" wheel, as long as they are the right offset.

I would be careful about tire width, going for a wide width may give you too tall of a side wall. I would run a 305/30/19.

 

thatst what i was worried about. anybody know what the offset should be with that wide of a wheel?? And will a 305 tire fit a 12" wheel?

 

I would imagine around 63mm..

Does anybody know for sure because this guys gonna call me on monday any i have to what kind of question to ask him lol.
any help would be great guys

 

Well the OEM GT3 wheels which are 19X8.5 ET 53mm and the rears are 19X12 ET ET68mm. Some of the Champion wheels that are made with 12" rear have a little more aggressive offset at 63mm, hence my original answer. If you want something more safe meet in the middle shall we say 65mm.

Here is your defenitive answer:

with a 12" wheel you can run a max size of 305-30-19 (a 325 would work but they dont make the proper profile for our cars)

the wheel needs to be between 61mm 70mm. anything in that range works.

here is a pic of my 19x12 gt3 wheels, 305 pilot cups and 68mm offset wheels with which i run a 5 mm spacer so a final offset of 63mm.

 

+1, I am with Ed on this one. I think you can even go up to 315/25/19 on the rear...

 

no you cant. that tire is way too short. it will look goofy with very little sidewall out back

 

That tire is so much shorter though..

 

As I know it when you increase the width of the tire the side/profile increases as well. You don't have to decrease the profile with every cm you add to the with but if you add between 2-3cm to your width you have to decrease the profile number in order to keep it balanced.

OEM Carrera tires are: 265/40/18 which translates to 265/35/19
OEM Carrera S tires are: 295/30/19

So this shows that you need to decrease the profile when you increase the width 2-3cm.

What do you think about that?

 

lol thanks guys now were getting somewhere. ill put some pictures up if i pick the wheels up tomorrow. On another note what do u guys think of the IFORGED TE14 wheels . They're one piece forged and supposedly really lite.

 

I was seriously considering getting those wheels. There are 2 problems:

1- For some reason I have heard that a lot of people had problems with iForged... There were couple of threads on the forum that the wheels were making noises and shaking... I talked to Dan from Vividracing and my dealership, they both said that it was poor quality.

2- If you really carefully check the pictures of the TE14 on the GT3 you will see that the holes are really close to the edge of the center... I don't know if it would be safe... I am attaching a picture for you to see what I mean.

 

I just received x1 of my rear rims from wheel boutique...damn UPS...., I have HRE P43's with 12" Rear and 325/25/20 PS2's on it, waiting for the other x3 to arrive but this was the fitment they recommended...I have c4S btw.
