Here's the wheels I decided on...

That sounds like a pretty big mileage hit. From 50 MPG to 40-45 MPG is a loss of as much as 20%.

Eh, not really, as I also noticed that I get worse mileage in warmer temps. Seems my Prius loves temps in the 70's.

Besides, it's not all about the MPG. It's also about how happy you are, as you save the planet. Remember, when I stop, I am still not polluting.

 

I agree with cairo94507 in that if it didn't pull to one side with the OEM wheels/tires and it does now I would check air pressure and if thats correct then rotate the front to the back to see if one of the new tires is bad. The Toyota dealer may charge you if they spend time on it and find it is due to the aftermarket wheels/tires. Have you had it up to Interstate speeds with no balance problems yet? It seems like whenever I replace tires I always have balance or pulling problems with the new set and have to go back to get it right. Michelin is the only brand I've never had a problem with.

 

Glad to hear that helped. Now you need to have the back tires checked for run-out. Sometimes, not often, it will show on the balance machine if you watch the tread as it spins. Also helps if they have the newer Hunter balancer and know how to use it.

On a side note, I was doing this post earlier while on IE and IE suddenly disappeared from the screen and now it just come up and goes right back down before I can stop it. So I am using Firefox now. Problem is my bookmarks on Firefox aren't up to date. Always something to do.

Edit: I turned off "third party extensions" and got IE back up. Now I don't know if there's a MS problem (because of updates) or a third party problem, which shouldn't be because I haven't added anything.
