Both these tyres are fairly good in terms of their performance and traction. But there are some clear distinctions.
Fuel Smart is basically a fuel-efficient tyre from CEAT. It has low rolling resistance and thus consumes less fuel. Customers in their feedback have mentioned around 7 to 10% increase in fuel efficiency. The tyre also offers confident dry and wet grip along with a good tread life.
CEAT Secura Drive however is a bit better in terms of grip and stability. This tyre performs really good over wet surfaces and also responds well to steering inputs.
So, if your priority is fuel efficiency and you drive at moderate speed then go for FuelSmarrt . But if you are looking at good high-speed stability and handling along with good wet and dry grip then go for Secura Drive.
In fact, due to good grip levels, SecuraDrive is being used as stock tyre on the latest Hyundai Verna.
