1995 C4 H28 code
Recently replaced my wheels on my c4 with c5 and tires are the only change. Within a day the following lights appear; ASR Off, ASR Service and ABS Service. Pulled the codes and have H28, H61 and H62. The warning lights only come on between 50 to 57 mph. If I stay below that range all is fine. Have checked break fluid all is well. Any advice welcome!

I suspect the difference in tire size between the front and rear tires is messing up the ABS/ASR. At higher speeds it probably thinks things are always slipping. If you still have the original wheels and tires you could put them back on and see if the issues go away.

If you have access to a scanner you could have someone watch what the wheel sensors see as you drive and see if it looks like a big difference between the front and back.
