Thanks to all for the comments. What is your opinion on the following three options I've uncovered?
1. Toyota dealer - new steel rims (obviously manufacturer original) - $80 each/$320 a set
2. After-market (Canadian Tire) - new steel rims (promoted as 'factory spec', but aftermarket supplier obviously) - $55 per/$220 per set
3. An auto parts supplier in my city - used steel rims from a Camry(s) (likely salvaged) - currently have four rims in stock, three from a 2009 Camry LE and one a 2007 LE (mine is an 07 LE). Auto parts supplier has been around since 1996, promotes the rims as fully inspected and has a 5-year warranty on the rims. $35 per/$140 per set
Some have suggested I go to independent salvage yards, but none in my area with Camry rims.
I'm only keeping the car another 3 years so cost matters and math doesn't work for me to do #1/dealer, so it's between 2 and 3. I’ve read/gotten mixed reviews of #2/aftermarket so I'm leaning to #3. Realize they come from salvage but with the history of the company, inspection and warranty it feels low risk. Only thing I wouldn't know is how many miles on the rims - is that an issue/what's typical maximum life/mileage on steel rims anyway?
Thanks for the input and tolerating the newbie questions!
