I just replaced my front wiper blades today and I noticed that the rear blade was a tad small (17"). I remembered that I had an unopened 20" blade, so I put it on the back. It fit perfectly. Is it a problem if I use a 20" on the back instead of the recommended 17"?

as long as the whole blade contacts the window ,and the corners dont stick up go for it.

Yea, I just rode out in the rain with it, it covers much more area. Works good. I just wonder why they didn't make it bigger from the factory?
