What is the Offset for a 2010 C30 wheel
 

Just wondering what the offset is for C30 rims on a 2010 model year car with 17 inch rims - has anyone got a clue. I am looking to buy a cheap set of aftermarket wheels, hence the question.

It seems buying a cheap set of aftermarket wheels is cheaper than buying second hand ones. I just need to get the right ones.

thanks,

ET/Offset 52.5

I bought a set of used refurb Volvo 16" alloys from these chaps for my winter tyres. From memory I think it was around £350ish delivered. Although they are an alloy PX company they do also sell for cash. Worth a try?

On a similar note, will these fit, assume so but the offset is slightly smaller.

Winter complete wheel for VOLVO S40 2.0 D (Type M 100kW), Rim DEZENT RE dark 6.50 x 16 (LK 5/108, OS 50) with Kumho KW27 M+S marking 205/55 R16 94V

Comes to about £640 for the 4 which seems reasonable to me.

ET is 52.5

I've got ET 40 which can run 225 front and 215 back - which dials out some of the understeer mine feels pretty balanced.

anything above ET 45 will allow you to run 225/45/17 front and back.

are these for winter tyres ?

Can anyone confirm these will deffo fit, don't want to buy them then have a big bill to send them back, pretty sure they should but you never know....

You've mixed that up. The lower the number, the further the rims come out of the wheel arches, the more distance there is between strut and rim... I've got 8,5" wide rims front and rear (each with 225s). If I went ET45, I would only be able to drive 225 on a 8" wide rim... The higher the ET number is, the further inwards the rim is... The lower the number, the more it will stick out... Thrus it isn't the tire size which is important, it is the rim width...

You can fit a 225 on a 7,5", 8" and 8,5" wide rim... Each have a different "position" in the wells - having the same ET.

I agree - That's exactly why it rubs at ET40 - it rubs against the exterior wheel arch! a higher ET would mean less rub against the exterior wheel arch....

Not on a C30 ;) I have exactly an ET40 with 225s at front and rear and a lowering but not a touch of rubbing...

But with higher ET (>40) with for example a width of 8.5" and the RIM will rub on the strut... My 8.5"s (with 225/35R19) have about 5 mm of room between rim edge and strut (front and rear). So at the same time, you ought to say, that a lower ET with the same width rim can cause rim rubbing and not tire rubbing... I could easily fit 235s at the rear, but the German TÜV says "nope".

Btw.: it isn't clever fitting narrower tyres at the rear, but I guess you already know why ;)

I'll leave you to have an argument with yourself!

215 on the back evens up the handing balance - just like the Audi RS3 which runs 225 front and 215 back :)
