Here is the deal im lookin for my next set of tires for my truck I Have A 1990 chevy k1500 with 9" of lift first off what size tire should I run 37 or 38s whay gears will I need 4.56? Now the tires im lookin at are Super Swamper M16. 37x13.50R15 Toyo Open Country MT 37x14.50R15 or Nitto Extreme Mud Graplers 38x14.50R15 which would be the best choice or non I have 35x15R15 SS TSL Bais now

 

The toyos with 4.56s wouldn't be bad

 

I've had Toyo's and Nitto's, but the TOYO MT gets my vote. They both offer good traction but the Toyo's lasted longer than the Mud Grapplers.

 

Thanks for y'all's help
