Hi, my name is Martin i'm from Poland.
First of all i'd to apologize for my english .

I'm 9000 anniversary user, 2xx HP, 1997' , 160.000 km .

my question:

i'd like to exchange my existing 205/60R15 wheels to brand new 17" x 7J alloy wheels.
It is possible to change that wheels without body rebulid (wings) ???
What tyres size will be best fiting, 215/45 , 225/45 (front) , 235/40 225/45 (rear)

Welcome to SaabScene Marcind!

I'm no expert on wheels, but I'm sure that's possible.

I'm also sure that someone else on the board will confirm this who has fitted 17" wheels to their car.

I think you should keep front and rear tyre sizes the same though.

Welcome to Saabscene Marcind.

What you need to do is to work out the rolling radius of your current wheels. Use the link below.

tyre size calculator

Basically, any wheel/tyre combination you choose needs to closely match your current setup to be sure that you don't suffer any wheelarch contact. Many people here run 215 or 225/45 tyres on 17" rims, but I know that ylee has managed to fit 235's on his Aero.

Good luck!

I'm currently running 225/45-17 on my 9k no problems at all. Be sure you get the correct ofset tough. I needed spacers to make some clearence on the front and rear tires. To prevent rubbing on the inside of the wheel.

Hello Martin,

5 months ago I changed my 16” x 7J three spokes for a sexy set of five spoke 17” x 7½J with 225/45 tyres. The only problem I had was with the inset of the wheel which was just contacting one of the handbrake cable hanger screws on the suspension lower arm. Easy fix though, I just moved the hanger back towards the hub by about 10mm. Of course, if you fit 18” wheels to start with, the rim edge would miss the hanger anyway.

Regards
Nick..

Whatever wheels you buy, you need to make sure they have the correct offset.

The spec offset for a 9000 on 6.5" wheels is 38mm. If you increase the width, you need to reduce the offset e.g. if you have 7.5" wheels, the offset drops to 25mm.

I've driven 9000s on 15, 16, 17 and 18" wheels.

The best compromise IMO is definitely 16".

I've gone for 17" and use 215/45 tyres with no rubbing problems on 40mm lower suspension. This size gives virtualy the same rolling diameter as stock tryes, and is only a little wider.

18" are uncomfortable unless you only drive on very smooth roads...

check this polish tuning online shop

they have few wheels for 9k.

One example:
TEAM DYNAMICS - SPEED 10 SILVER -- SAAB 9000, ROK 87 > 98 :: 4X108, ø65,1, ET 25 ; ROZMIAR : 7'' X 17'' - offset is corresct?????

2nd example:
TEAM DYNAMICS - DIABLO HI POWER SILVER -- SAAB 9000, ROK 87 > 98 :: 4X108, ø65,1, ET 25 ; ROZMIAR : 7,5'' X 17''

ET is the same in 7,5 and 7 ???????

Why would you have different size rears? The Saab is FWD, theres no need for that.

Yes, those offsets are OK... the correct offset is 25 at 7.5. At 7 it should really be 31, but it's not a very big difference so it is OK (5-6mm difference from stock is normally OK)

It is not possible to fit a 9000 with 9-5 rims, because a 9-5 uses 5 bolts and the 9k 4.
My 9k is fitted with AZEV c-type wheels with 215-45-17 tyres on the front and 235-40-17 (!) on the rear. But for the rear I needed spacers. But the result is

Hi....
trying to get a little clarification.

got a 94 aero with the factory super aero rim. 6.5x16 with .27 offset
I want to have a 17 inch rim. what offset do i need if i use the 7x17 rim? is there an advantage to using 7.5x17? what would the offset be for that size?

tks in advance.

How/why does the offset change with rim width?

I thought the centreline of the rim should remain constant (side-to-side) i.e. with respect to the rest of the suspension geometry, so the scrub radius doesn't change (etc).
