Hey guys,

Here's the story:


Today i brought in my new set of wheels (17x7.5 +45mm offset) to get tires fitted. The tyres were 225/50 17R and fit fine with a tiny bit of overhang. The guys at the tyre place fitted and balanced the wheels and tyres and said that everything was perfect. So i drive off and all of a sudden i listen carefully and i hear some scrapping noises coming from the rear. So i check it out and see that the inside tyre walls/profile is scrapping against the edge of my Koni shocks!!! About 0.5cm of the tyre profille was rubbed and melted down with it all the rubber flinging into my guards! I was so scared (and pissed off) at that point that it might cause an accident, so i called the tire place. By that time, i was at home and they said to put back the original 15' wheels which i did do. This brings me to drama #2.

I got around to taking off the front right tire, when all of a sudden my jack collapes!!! My A4 just goes BANG into the pavement (leaving a hole in it too), landing on the bottom bolt on the lower suspension arm. I am in shock at this moment.. lol. So i jacked up the rear end and used a 2nd jack to get the front back up.

Ok, so at this point i got the original wheels back on and took the car for a drive around to see if my car is a goner. The only apparent problems so far from the car destroying my driveway are:

*Having to hold the steering wheel 20 degrees to the right to center the line of travel as if the wheel (or maybe even suspension.....!) allignment is off
*The illumination of my speedo/etc. and air con. has gone dimmer!?!?

Everything else seems ok though.


Also once i get over today's drama, i was thinking of what am i going to do with the wheels. I'll obviously expect new tires from those "tire professionals", but i'll still have the rubbing problem at the back. I was thinking of 2 options:

1) Change rear Koni shocks (they are old school non-adjustables) to coilovers - will these or any other shocks give more clearance for the tires? (Its the wide middle part of the Koni shock body that rubs - so i need shocks that have a smaller middle body)
2) Put back the original shocks (which i don't have..) with new springs?

The offset of the wheels are 45mm, and they're Audi replicas and was told they'd fit.. but maybe they would only fit ok with the stock shocks? (i don't want to get 10mm spacers as they would then hit the guards/fenders)


Thanks for those who have come to read this far! So pretty much i was hoping if anyone could give me some advice/suggestions on:

*Having to hold the steering wheel 20 degrees to the right to center the line of travel as if the wheel/suspension allignment is off
*Any other things that i should look out for cos the car hit the ground!
*How i can fix the sudden dimness illumination of my speedo/air con., etc.
and
*The change of suspension to fit the wheels

Thanks in advance.. wish me for better luck with my car :)

Doesn't sound like you've been having much luck! First of all i would suggest using axle stands if your working on your car.

Coilovers would free up a little more space cos there a lot thinner. Is the car lowered at all? Cos it seems strange that its rubbing.

I don't think you are going to be able to fit those wheels and tires on your car regardless of what you do except using spacers AND rolling the fender lips - if even then.

The problem is that the tires are too big. Stock 17" equivalent tires are 225/45-17 which are 24.9" in diameter. Your 225/50 tires are 25.9" in diameter - bigger by an inch.

Not only that, but the wheel is 1/2" wider and with the same backspacing (ET) or 45mm the inside rim lip is 1/4" closer to the suspension. That in combination with the tire size is what is causing your problem - the rubbing on the inside suspension members.

Did the tire dealer say these tires were the correct size for this car? If they did, then take the tires back and get the correct size. Once they are on the rims, then get a set of 5mm or 10mm spacers. Many 17 x 8 and 17x7.5 wheels have an ET of 35 - 38 to move the wheel and tire outward to avoid this problem.

No coilover shock setup in the rear will be skinnier than plain shocks and the separate springs so I would forget that idea. You may have to call around to find the smallest performance shock - whether it's Koni, Bilstein, stock sport suspension shock or other brand.

You quite likely have bent your suspension. I would take the car to a good alignment shop and have them do an alignment, or if something is bent and it can't be aligned, then get that fixed. You don't want your car falling apart as you drive down the road.

Good Luck!

Correct offset figure for B6 A4 (2003)

I know this is an old post to be going back to but I'm new to this forum and i may have missed many earlier posts on this subject. I need some advice urgently.

I'm thinking of buying a used set of original, genuine Audi wheels (17x7.5) with an offset ET56mm (coming off an Audi A3 2007). It comes fitted with tyre size: 225/45/17) Would these wheels (with the tyres currently fitted) fit okay on my B6 A4 (2003)?

Currently my B6 A4 is still fitted with original Audi stock wheels (16x7) with an offset ET42mm (current tyre: 215/55/16)

In any case what is the correct ET figure for the B6 A4, and how far could I deviate from that figure and still be okay?

The few posts i have read on this forum on the subject are extremely confusing - different ET numbers (for the 17x7.5) wheel are thrown about (35mm - 45mm). What are the offset limits for the 17x7.5 wheel (for the B6 A4 beyond which i would need spacers? I wouldn't want to use spacers on the car.
