Title: 17" wheels - Will these fit?
Post by: JayUK on 08 December 2006, 16:56:28
OK, I've done a search and either missed the info or am just too dumb to understand it all. :-/  Answers on a postcard....

Anyways. I want to put some 17" wheels on my 3.2 Plodmobile. I think there's just too much rubber showing on the 16" at the moment.

Browsing through the delights of ebay, I've found these 2. I'm wondering if they'll fit and if so what people think of 'em.

Cheers! J

I think the offset might be different for a Vectra? I'm sure someone else will confirm.

I couldn't be definate on whether they could fit you would need to confirm the car they are made for has the same pcd/offset I think omega are fitment 5x110

If they are the same then I dont see there being a problem

Try here to make a comparison for fitment.

The 17s fitted as standard are 7 1/2 J 17, ET39 (i think)

The tyre size you need to go for is 235/ 45 with a rating of 94 W or better if its a 3ltr or 94 V or better if its anything else.

Think the ET 41 will be ok, but the tyres will give the incorrect rolling diameter which will affect your speedo, but by how much i'm not sure

They are quoting the wrong size tyres, so could mess up the spedo and odometer readings

From what i remember all vaux v6's have the same et which coinsidentally is also the same as the 5 stud saab fitment the main difference is the tyre size. I also remember that i think it was the wolfrace wheels required a spacer but there are several good wheel guys around that can help you with tyre sizing elc etc.
