2nd Gen Non-Engine/Transmission Tires

[RPMDodge]

Does bigger tires lower rpms on highway speeds? Better fuel mileage? Thanks Rick... .

Rick, Yes they lower RPM. Torque on the other hand will be noticeably lower as well.



Fuel milage depends on how you drive, one or two tire sizes will not make much of a difference.
