Hey guys,
Pulled a few error codes from my BF XR8...

Put some new rims on (still 18" only 35 profile instead of 40) and started getting ABS/DSC lights staying on, sometimes both, sometimes just the DSC, sometimes none.

What should I look for?

OBD2 Codes are...

RXE (Pending Fault)
ROR (Pending Fault)
U1900 - Network
C1222 - Chassis
C11<R - Chassis
P20E5 - Powertrain
P2000 - Powertrain
P1934 - Powertrain

They all 'seem' to be speed control sensor faults according to google but what do I need to replace to fix?

Cheers all!

You've changed the rolling diameter too much by the sounds of it. Change your tyres.
