Can I change tire size from 245/40/18 to 235/40/18 without any issues on my 2013 Audi A4 Premium Plus?

    you need to stick with the ones your vehicle is equipped with from factory. Wrong size tires can cause the vehicle to be off balance .

Hi there, 
No. The size 235/40R18 is incompatible with the 2013 Audi A4 Quattro Premium Plus 2.0L. The other tire size allowed is 235/45R18 (besides the standard tire size of 245/40R18). Unfortunately, we do not carry tires in our inventory at the moment. I hope this helps.

    For sure you can. They will be slightly smaller and it might asthetically look a little goofy but it shouldn't negatively effect your ride safety or quality. Unless it's just one tire you are planning on switching then you probably should not do that.

    Yes you can. You shouldn't really feel a difference other than height of the car. The first set of numbers represents the height of the tire. If factory tire size is 245/40/18 then it wouldn't be advised to go up in height but you can go down and have no issues. Any higher than 245 will more than likely rub the fender well.  I hope this answers your question
