Default Replacing stock tires

I was trying to replace the rear stock 255/35 r18 for 255/40 or 45 r18 any one has tried this or is there any other size you would recommend for a better everyday ride quality. My city has a lot of potholes.

Bottom line - yes, you can do it, but it has drawbacks. Most notably, the speedometer will be slightly inaccurate. Also, if you have AWD, you will need to up-size the front tires as well.
