I have more than tried the search function... looked through many threads and its overwhelming. just had to ask
In this case, DON'T search.... for too long, at least!
(I don't think there has been anything ever posted here, about this topic. Most M135 owners seem to prefer keeping their rigs all stock/ original...)
Wishing I had a M135 here to confirm 100%... If your Q. was about A3 wheels with stock A3 tires (14.5R20 or 365/80R20) that should work all right: tire O.D. plus hole size and bolt pattern for both wheel centers are the same, no problem; only the A3's have about 1" more backspace.
Now 395's are a lot more rubber, sticking out in every direction! So there might be some interference issues on steering components, fenders, etc. Also, this would be considerably more weight on the front axle; don't know about the original shocks....?
Let us know and post pics if/when this project comes through!
