Does the computer figure it out that there are different tire sizes or does it have a larger tolerance that you mention above.
Do you think this impacts ABS from functioning?
thanks

Your assumption doesn't include the aspect ratio. Corrections below:
20s - 275/40 (728mm tall) & 315/35 (728mm tall) - 0% delta (0.5% delta from OEM)
21s - 285/35 (733mm tall) & 325/30 (729mm tall) - .5% delta (OEM)
22s - 295/30 (737mm tall) & 335/25 (727mm tall) - 1.3% delta (0.8% delta compared to OEM)
OEM computers will not throw a code if it's within 1.5% from OEM spec. You are completely fine.
