Yes, you will benefit from a lower gear ratio, and no, you don't need 35" tires to do it. The taller gear will lighten the load on your engine and drive train and mathematically change the number of times the axles turn in relation to the number of times the drives haft turns. Disregard anything anyone else tells you about this. It's not opinion, it's MATH.
A stall converter is actually called a torque converter, not a stall converter. All torque converters have a rating called the stall rating. It is the engine rpm where it begins to couple the engine and transmission, as the torque converter is the fluid coupler between the engine and transmission. A factory torque converter has a very low rpm stall rating. Performance oriented torque converters stall at a higher rpm. A higher stall rating benefits a combination of engine transmission tire size gearing and weight by bringing in the engine's power at the right rpm to launch the vehicle based on the engines torque peak.
