recently changed tires from 275/35/19(rear) and 245/35/19(front) to 275/45/19(rear) and 245/45/19(fronts) car seems to handle about the same but seems alittle different performance wise..then the other day i got down on it a bit and car went into limp mode. my ses light has been comming on and off every 300mi or so but this was going on b4 tire swap..could have something to do with it...was just curious if tire size may be a factor...thanks members

 

anyone?
