Have a 2005 Chevy Suburban 3/4, 4x4, 8.1L. C ame with 245-75-r16 tires. I came across a good buy on some 265-75-r16 tires. I know they will alter my mechanical speedometer reading but what about the driver data provided by the computer such as: mpg and miles remaining until empty? Will they mess that up to? If so, how can I restore its accuracy and still use the larger tires?
