Retrohsnevets Posted December 13, 2011 Report Share Posted December 13, 2011 Hello I have an A6 Avant, Le Mans. 'Standard' 8x19" Le Mans Alloys. ET48. I want to put more traditional 18" S-Line Alloys on with a set of Winter Tyres I have in storage, taken off my S4 Avant, now sold. The S-Line 8x18" Alloys I have in mind are ET43, however, there are more recent Audi rims that would fit the A6 with ET47. The winter tyres I have are 235/40 r18 XL. The current tyres on the 19" rims are 255/30 r19. Question: What is the ideal offset for 18" rims with 235 wide tyres? What affect might the difference offsets have on steering, etc? Thanks.

Andy_Bangle Posted December 13, 2011 Report Share Posted December 13, 2011 (edited) Much would depend on the years of the two cars: B8 centrebore is 66.6, A6 (2004-11) CB is 57.1 although this can be fixed with spigot rings. The different offsets won't have much difference on steering as the tyres will only extend an extra 5mm from the suspension strut. Also, your speedo will be only be 1mph out at 70mph.

Retrohsnevets Posted December 13, 2011 Author Report Share Posted December 13, 2011 Thanks. It's a 2008 A6 Avant, if that makes any difference? Also, it's only the winter tyres that I have from the S4, not the rims. The rims I am looking at are the usual A6 S-Line 18" rim, that are generically known as 'RS6' alloys, part number 8EO 601 025 AK. Link to comment Share on other sites More sharing options...
DanG Posted December 14, 2011 Report Share Posted December 14, 2011 Annoyingly, C6 wheels will not fit a C7 A6 either we have just discovered..... So £1100 worth of Brand new, unused OEM 17" wheels and 225 winter tyres will be on here / eBay shortly. Oh, and it's £1500 for a set of C7 winter wheels and tyres.... Feck it.

crasha Posted December 22, 2011 Report Share Posted December 22, 2011 Searching through the various options for winter tyres is proving somewhat difficult for me too. Trying to find a set for a 2011 A6 C6 4F S-line Quattro... looks like some 17 inchers may be available... Link to comment Share on other sites More sharing options...
