Regearing

I am upgrading my tires to 265/75/r16 ATs
My gear ratio is 3.73
Should I upgrade to 4.10 or keep it stock? I plan on leveling the front as well

 

No need to regear with that set up. Unless you really want to. But not needed and very costly

 

Do you think it will effect performance in regards to towing around 3,000?

 

For that tire size it would be a waste of money in my opinion. That's a 31.6" tire which is basically the same size as factory/oem tires.

Regearing isn't really beneficial unless you change the overall radius of the tire (33", 35", etc) or dramatically increase weight (thus needing more low end torque).

 

You won't even notice the difference
