I had factory tires that were about 30.4" then I put the new tahoe 20"s on with a 31.9" tire when I got the truck. since then I have done everything in my sig and am still thinkin I need more torque. So I guess my question is if I put on a 30" tire which 1.9" smaller than the tires I have now would the gain be worth the money spent on new tires? It would be about the equivalent of switching from 3.73 to 3.96 gears.

 

with the drop in rotating weight also. Yeah, if they look good.

 

yeah thats the thing idk if a 2" smaller tire would look funny or not. I dont think it would be too bad.

 

Go for it.
