Iam trying to find people who have run the 345/30/19 tires on the rear and the 275/35/18 on the front. I have heard that the larger diameter tire can cause a code light for the ABS. I have not found enough people with this combo to tell me if they have had any problems. I have talked to one place that said they had a customer with that combo and they had not heard of any problems. So I'm asking if anyone else with a later year, 2001-03, C5 with this combo to tell me if they have had any issues. Also if anyone has anything to add please let me know. Thanks
