Tyre size help (Audi S3/S4/S8 Style 19")

[Amir]

As above really, I'm looking at buying the above wheel but possibly without a tyre as I'll source my own as I don't want budget tyres on them that come already.

What size is best? I've looked at the places that sell them on ebay 1 advert says 4 X 255/40/19 HIGH PERFORMANCE TYRES other advert says 4 X 235/35/19 HIGH PERFORMANCE TYRES.

Which one should I go for? What are the pros/cons if any. If it helps the car is a A4 1.9TDI Avant Sline B6 .. It'll be carrying heck of alot of weight in the boot possibly upto 250kg even! I'll be ordering custom springs for the back and lowering the frnt with normal springs

I have 19X8 rs6 reps on mine with an offset of 35 and pcd 112 tyres are 235x35x19, I would suggest looking for some extra load rated tyres by the sounds of it. Also alloys have a load that they are safe to carry aswell and oem alloys are a lot stronger than replicas, just thinking that with possibly 250kg in the boot aswell as the car weight they are supporting over a bump would create a considerable downward force.

235/35 x 19 would be a normal tyre size with a 19" wheel. Hard to say without knowing the offset, but 255 is an RS4 size and I think would be too wide for an A4.
