I have a 2005 -2500 HD 6.6 diesel with 40 inch tires 10 inch lift what gear ratio will work better for that size tires in the city of Springfield Oregon

Your truck came with 3.73's, now it needs 4.56's..

Hope you like spending money..

4.56's won't even cut it with that large of tire.

4.88's or 5.13's at a minimum for such massive and heavy tires.

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
