Speedo doesn't work after wheel swap

Tombonombona

So I swapped back to the stock wheels, all the gauges and warning lights fixed themselves after driving for like fifty feet... I put the "bigger" wheels on and within a mile, I lose my speedo, trac, abs, rev match, and the car doesn't think the key is in it so it's hard to turn off...... but if I go around a tight corner and give it a bit of gas, it seems to fix itself, but then after a mile I lose everything.

Very confused as to why these wheels worked for two years and now they don't. I really don't want to have to spend $1300 on new rear rubber when the ones on there have been barely used.
