I have 18"s on my 06 Camry and it is time to buy new tires. I can stick with the size on them currently (225/40zr/18), or tirerack suggests (225/45/18), or I would like to go up to a 235/40/18. What should I do? Do 235s fit without rubbing? What have any of you out there gone with and had nice results?

 

235 kinda wider unless you are using 19" rims with offset 45.
for your 18" rims better 225/45/18 correct size and for Fuel Consumption as well but 235/40/18 should be fit into your camry depends on your rim model.
