A4 Avant Quattro S-line wheel/tyre combination

[agbucks]

i have an '09 A4 on 255/35/19 alloys. in preparation for winter trips to france, i want to buy a set of second hand alloys and a set of 235/45/17 winter tyres.

will any audi 17inch rims fit? if not, what spec of wheel ie offset etc do i need?

thanks,
andy

If its a B8 new shape (and I'm guessing by the size you've said it is) then none of the older type wheels will fit as the centre bore on the new wheels is larger so the only 17's that will fit will be ones from new shape A4/A5's. Be wary of replicas as the offset is unlikely to be correct. The new ones will be 5x112 ET32

thanks. it is the B8 shape so will keep an eye out for the wheel you have specified.

These ones would fit, note higher offset due to narrower wheels (sale nothing to do with me by the way...)

Changing the tyres sizes that much represents a change in rolling diameter by 2.72%. Etyres recommend a change of no more than 2.5% maximum. Your total diameter will be 19mm smaller. The speedo will be innacurate, it will over read by 1.6mph at 60 mph, so not the end of the world, under reading is illegal. But do check with your insurer.

sorry, what is 'ET' and what is the difference between et32 and the ebay auction set et28?
thanks,

et is the offset of the wheel, so an et28 wheel has the mounting face offset by 28mm from the centre line of the wheel. As a previous poster said, this is just to account for the narrower wheel.

As an aside, i was always told anything up to 6% was acceptable, especially when you consider the range of wheel/tyre sizes fitted to different trim levels thoughout a range of cars.
