    I saw this:

    2010 Prius
    15X6J: 5X100mm PCD, 45mm offset
    15inch: 7.4kg - 16.3 lbs

    Written by David Beale here. Can somebody confirm if that weight is correct? I've been looking around and I get conflicting info; what's an official source for wheels weights? I'm def not putting in the right words when researching.

    I wanna buy Motegi MR116 for summer and they weigh 16 lbs. If it's the same weight good - if not: I might reconsider.

    EDIT: MR116 in silver are not in stock. Switching for Enkei J10, just want to confirm 14.4 lbs weight - some websites list it as 17 lbs and it's not right ottomh.

    Why fret over a pound or two or three? Buy the wheels you like to look at and run those. If you are not autocrossing or drag racing a lighter weight wheel that will give you a few tenths of a second faster race time will not matter on a street car. If you are worried about using more fuel with a lighter weight wheel, I think it will be minimal.

    Our stock 3rd gen 17" are around 24 lbs IIRC. It's the cross I bear... :rolleyes:

    I heard it wasn't that minimal. Either way, I liked those Enkei, I was considering them since last year.

    Mine came with 15" original wheels. I heard they might be 16lbs or so, so I didn't want to go over too much.

    Unsprung mass has way more effect than spung (the car body) mass. Especially if that unsprung mass is also rotational mass. The general rule of thumb is that every 10 lbs of mass above the suspension is the equivalent to 1hp of power gained or lost depending on if you are adding or removing the mass. Rotational mass is roughly 4 -5 times as effective at robbing hp since the power train has to spin that weight to move the car. Unsprung mass also greatly affects your handling since it's easier to keep a lighter object in contact with the road vs a heavier one. A difference of 5lbs per wheel would be noticeable to the driver even during normal street usage. Things you'd notice(assuming a drop in 5 lbs per corner) are better acceleration , handling, and fuel consumption. This is because the engine and suspension doesn't have to work as hard to rotate the wheels or keep them on the road. And yeah I know this is a really old post

    My Ray's Supereco 15" rims are only about 8lbs.

    Do you feel a big difference when driving?

    Take off and turns are quicker.
