Need advice on tire Size - 17 inch Wheels / 2009 Vibe

[Carbon09]

I think I want a little more sidewall than the factory 215/45r17 (just bought some factory 17s) would give me. What size tire would work well? I have come up with two options, any others you recommend?The two options I have come up with are:225/45r17 - This size would have a 4 inch sidewall (compared to 4.4 inches) and a .4% diff in circumference from my factory 16" tires of 205/55r16215/50r17 - This size would have a 4.2 inch sidewall (compared to 4.4 inches) and a 2.4% diff in circumference from my factory 16" tiresThanks

How about some 235 45 17s? They are an optional size according to Discount Tires.com and have a 4.2" sidewall. I'm putting a set of 245 45 17s on my son's Vibe with the 17" wheels shortly. They may be a bit tall, but I like a little bit of a wider tire especially with alloy wheels to protect them a bit more.
