It is on the high side but it does give more sidewall and less fender gap but your speedometer will be off by 4.7% and it's too much, when you hit 60 mph on the speedometer you are actually hitting 62.8 mph so it makes it slower. Also it will be 15mm higher than before. The closest tire that is to stock on the 4 cylinder camry is 215/40/18.
Use this tire calculator and try something else, you can go ahead and try 225/40 or 235/40 if you want a lil more sidewall and don't mind sacrificing a lil slower speedometer readings but it shouldn't be as much 45 series tires. Also depends on the width of the rim. 5sfe camry's started out with 195/70/14 so you get different numbers compared to the V6 camry cause that started out with 205/65/15 just to inform people!!!
