I have a 2005 A4 with rs4 wheels and i'm planning to buy a new set of tires for my car. Right now they are rolling on Continental SportContact 2 size 235/40/18 and they freakin cost like $250 a piece. So I decided that I want to go with all season tires instead. I decided to go with Continental ContiExtremeContact but im debating on what size? Which size would be good for me? Can i get away with the cheapest bcus im kinda broke.

235/40ZR18 $130 each (what i have on now)
225/45ZR18 $118 each
225/40ZR18 $107 each

 

I would go with the same size you have now.

Im running 225/45/17 Id rather have 235 if my rim can handle it.

I have the contiextremecontact tires on mine, I like them. They slid around a little to much for autox, but thats only because I need a set of rims with slicks to hold this heavy quattropig on the road!

 

get the 235/40zr18. dont get a smaller tire that will make your car handle worse

 

deff get same size there is no reason to go smaller, remember bigger is ALWAYS better

 

not always. the bigger you go the harder it is to turn the car.
