I am considering putting the 2015 Malibu LTZ 2LZ 5 spoke rims on my 2016 Impala LTZ. Bolt patterns for both look to be the same at 5 x 120mm. Offset on Malibu is 41mm, Impala is 45mm.
Anyone know if this swap will work or not?
Mr Blackwell (gotta love that handle
For a 2016 Impala (new body style), the parameters are:
5x120mm, center bore= 66.9 mm, and thread size = M14 x 1.5mm
For a 2015 Malibu, I get:
5x120mm, center bore= 67.1 mm, thread size= M14 x 1.5mm
Both the Malibu and the new Impala share the epsilon2 platform, so I would expect the wheels to match up. Both show 5x120 and M14x1.5, but the center bore numbers don't gibe.
You may need some centering rings (ie, hubcentric rings). My only concern is that, to get from 66.9 to 67.1 mm requires a paper thin ring, so I'm not sure that's viable. Furthermore, every wheel I find for the Malibu seems to have a different center bore listed, so I'm not sure which numbers to trust yet.
To be clear, these wheels center on the wheel hub, so it's important they match, or use a proper adapter. It's not like the old days where, on many cars, the wheels were positioned on center by the studs.
And it could be that both those numbers were mangled by some data entry clerk who doesn't understand conversion, rounding and significant digits, meaning they may actually represent the same value
As for the offset, I wouldn't worry about 4mm difference. That's a ~sixth of an inch. The variations in tire width will probably be greater than that.
For a first pass, I'd say they are compatible. I'll keep poking around and, if I find some reassuring data on the center bore, I'll post back.
