i'm putting 205/50R17 nokian entyre2.0 tires on when my tires are ready to be replaced. just put them on my daughters Rav4 and have ran them on my prius. i LOVE these tires. the sidewall 50 and below are 60k mile tires. but these tires are amazing in all weather conditions and get great gas mileage.
i get them at walmart.com just search for nokian entyre 2.0 and find your size. their site is broken so that is how i find them and they are at a great price.

Replace them with the proper diameter 225/45R17 tires. The 205/50R17 will also work but won't perform as well being a narrower tire. I use the 205/50R17 tire size for my winter tires where the narrower width is desired. For the other 3 seasons I prefer the better handling and braking that the wider 225/45R17 tire can provide. They are both the same diameter where the OEM 215/45R17 tire size is actually one size too small. Funny how the Corolla iM came with the proper 225/45R17 from the factory.

right now i have the original tires which are P215/45PR17 but i want more tire! more sidewall not width without compromising the car overall!!
norfolkcbc, i've been thinking about this off and on since you posted. that size tire, there really isn't another size in a R17 wheel that will keep to the 24.6 inch diameter. you could go to a 16 inch rim, like what is on the 2017 corolla LE, and would have more options for tire sizes to keep at that diameter. 215/50R16 = 24.5X8.5R16 or 185/60R16 = 24.7X7.3R16 (this size is over an inch narrower than your stock size).
your current size info 215/45R17 = 24.6x8.5R17

The problem is that the 215/45R17 is the only tire size that Toyota uses that is the smaller 24.6" diameter. Here are the tires that are used by Toyota with some options too.

195/65R15 25.0" diameter
205/55R16 24.9"
205/50R17 25.1"
215/45R17 24.6"
225/50R17 25.0"
225/40R18 25.0"

As you can see it's much smaller than every other diameter that is used. So do it right and go with the 205/50R17 or 225/45R17. :)

So the question on my mind. Did toyota calibrate the se for the 24.6 inch diameter tire? And if he goes with a bigger diameter tire will it cause the odometer and speedometer to be off?

The 225/45R17 will help correct the speedometer error that is present on Corollas with 215/45R17 tires. This is why Corolla owners have been making the swap for a decade now.

to be honest, every toyota i have ever owned has the speedometer off. out of the 4 toyotas 1 currently have, each one is off by 1 to 3mph. usually showing higher speed than what is actually driving. my iM shows 1 mph lower than actual no matter what speed i am driving. its weird.

My Corolla iM is spot on as is my 2017 RAV4. Most of my other cars of all brands read fast like you have seen too. My 2009 Corolla S became closer to actual when I installed my 225/45R17 tires. It's a no brainer to upgrade from the too small 215/45R17 tires. You get a little more sidewall which can help ride quality and can protect the rim better. It's also wider and can provide better handling and cornering. I someone wants better ride quality and to maximize MPG then go to a 205/50R17.
