Think about running cooper zeon 275 60 20 with 5.3 engine. Just curious who was running these and what kind of mpg you were getting. Thanks for the info

I haven't been impressed with the fuel milage. I'm running a 275 55 20 and the truck is only getting 13.4 to 13.6. With the stock wheels it was right at 15. These are around town numbers.

I have a 2010 GMC Sierra 5.3L.. with the Cooper Discoverer running 275-60-R20.. I was getting around 20mpgs with stock before but now I am getting around 18mpgs that is mostly highway miles.. I live in the middle of no where so

I have them in that size and consistently get mid 12 mpg's.

 

2008 1500 ex-cab

5.3

4 speed

3.73 gears

Airaid MIT/K&N filter

Borla/GM "sport" cat-back

Blackbear tuned to 89 octane w/AFM turned off

 

That being said, when I make the 400 mile trip to my sisters I will get about 21-23 mpg which is great.
