Will some 2007 Lexus GX470 Rims fit on a 1991 Lexus LS400

Probably not.

all you need to do is go outside and count the knobs that the socket holds the tires. If they have the same amount of sockets that holds the tire together than it will fix. And check on the size of the socket too ok.

l have a nissan and my brother give me his honda accord rims to me and it fix.

Absolutely not. l have a GX 470 & know that they wo not fit on the car. On top of that, the LS may not run or drive properly with aftermarket rims on it. Lexus specifically designs their cars to run as best as they will with the things they come with. l know someone who has a GS model & had aftermarket rims, tires, brakes & a bunch of engine mods done to it. After about the first ten miles, the car literally started to ''freak out'' & went into limp-mode, which means the car did about 30 MPH back to the dealership. He had everything switched back over & the car has been perfect ever since. If u r going to change rims, make sure they're the same size as the old ones. The GX ones would not fit anyway..it is an SUV vs. a sedan.

different gx470 are 6 lugs and ls400 are 5 lug completly diff.
