vauxhall omega alloys - gingerwinger
i have just changed my alloys with the 2003 cdx alloys. but on the back of the alloys the et is 39 (offset) but on my older alloys the et is 33 (offset) the pcd is still the same. i have gone from 205/65/15 to 225/55/16. will the offset make any difference as the et is +6. the car is a 2.5 v6 auto cd.
