Hello everyone,
I purchased a 07 avalanche ltz last year. I have to buy a set of tires and a spare. I noticed the truck has 275/60 instead of 275/55. I'm wondering if the speedometer
is accurate using this size tire. Does anyone use this size?


Thanks for your help in advance,

 

if would be off a small bit. easily confirmed with a gps. with a scan tool you can go into the ebcm and set the tire size to match the tire size you are running.

 

Thanks, Appreciate the reply. I'm going to use the correct size.
