2016 Q5 wheel offset limits?
 

I have a 2016 Q5 TDI with 18" rims with an offset of +39mm, the rims I want are +35mm and I plan on running the stock tire 235/60/18. Am I looking for trouble changing the offset, As I don't want trouble as its the wife's car. Any input would be helpful and also a new member and Audi owner here..cheers!

Nope, you'll be fine. You'd only need to worry if you were going with a higher offset or far enough out to worry about rubbing, which you won't in this case. Make sure you use the proper bolts for the new wheels.

We've done offsets for the Q5 ranging from +30-42 so you should not have any issues

Well had the tires mounted and balanced today and installed myself , all seems good, mabey a little more Preasure on the wheel when takings Corners at normal speed with the extra 4mm offset per rim, would have liked larger rims but it don't make sense as I live in Rural area and roads are crap and q5 rides firm enough for me...thanks again for the replies.

Stock bolts ended up working with these rims, thank you.

The wheels look good. You do understand that StopSign was referring to the type of lug bolt?

Either ball seat or conical will tighten up ("work"), but only one will be seating correctly in the wheel. Audi OEM wheels use ball seat bolts, whilst most aftermarket wheels need conical bolts. As your wheels look like replicas, they probably do have ball seats but worth double checking if you haven't already done so.

Audi use an offset of ET36 on the 20" wheel option, which is also using an 8" wheel width and 235mm tyre. I don't know the specific scrub radius Audi are using on your Q5, but typically Audi run around negative 8mm. As you are using the same tyre width, there is a direct correlation between offset and scrub radius, so you have only moved 4mm closer to zero scrub (zero or positive scrub results in steering instability under braking for AWD). So no problem at all - you obviously have a good feel for the car to notice the slight increase in steering weight under load.

Thanks for the info Glisse, the tire shop that mounted the tires on the rims and balanced them confirmed I can use the stock wheel bolts with these rims. The added pressure is noticeable in steering but not bad as these have pretty light twichy steering in stock form anyways. I was not aware of the 2 types of bolts but going to double check today. Thank you.
