I found a set of 14" rims from a 740. I was wondering if they would fit my 1990 240.

 

they should fit just fine. 240 sedan used 185/70-14 tires, I believe. wagon might be a size larger. (the 740 probably had significantly wider/larger rubber on it).

do try and verify they are straight. nothing worse than buying some rims then finding out 1-2 of them are bent when they get put on the spin balancer...

 

Thanks. I will check them as best as I can!

 

in a pinch, I've jacked a wheel of my car, taken off that tire, mounted the rim just lightly tightening and spinn it by hand, using a pencil or something held against something stationary as a gauge to compare wobble...... repeat for all 4, then put your wheel back.
