Hello, I'm using my Q7 to tow my travel trailer with is just under 4K lbs fully loaded and an appromimate toung weight of around 350lbs. I currently have the stock tires and rims (20") and I want to replace them with something more stylish. I'm currently looking at a set of 20" Vossen rims, but started to think about going with the 22" rims as they are an option for the Q7. If I keep the tire ratio, I'm guessing I'll be going from a 275/45R20 to a 285/35R22. Since the sideway will drop in height by a bit in order to keep the same overall diameter, what are the thoughts on having the 22" rims and still towing.

I do expect the ride to feel a little stiffer, but are there ay mechanical or safety concerns? I assume that since the Q7 does come with 22" rims in some models, the only change would be felt in the comfort, but wanted to ask.

thanks in advance.

 

play with the different parameters, here, to get the wheel nsize you're in search of:

Ya, I checked that site to figure out the replacement size if I move up. The bigger concern(less now that I looked for tires) is the load capabilities of the 22" tires if I moved to them. It's looking in like I'll loose load rating if I go to 22s so may stick to 20s to play it safe.

Thanks for the link and reply though.
