I own a Swift petrol car with Tornado stock tires from JK Tires in India, so if I go for wider tires with alloys wheels for Swift, what is the effect on mileage?
Many people have this perception that wider rubber tires will affect the fuel efficiency very badly but it is not true. If you buy good brand of tires with good alloy and drive sensibly, the reduction in fuel efficiency would be negligible. One of my close friends has 205/55/R15 Michelin Pilot Preceda 2 which is the best performance tire in its range and he is getting 18 to 19 kmpl in city with AC on in his Swift.
Benefits of Alloy Wheels in Car
You need to remember one thing that buying alloy wheels from good brands have numerous benefits as:
Alloy wheels are lighter than steel rims and the unsprung weight reduces and suspension performs better.
Alloy wheels have better ventilation due to their design, the rims and tyres run cooler, hence more tire life and less chances of burst or puncture.
Alloy Wheels also have better shock absorption for more comfortable ride.
Tubeless tires fit best on an alloy rim and form the best contact patch.
As the unsprung weight is less, vehicle acceleration and fuel efficiency also improves though by little margin.

What is the Right Tire Pressure in Cars
For cars like Swift diesel and petrol, 33 at front and 30 at rear is the ideal pressure and mind it that lower or higher, both will affect your car’s suspension and tires in an adverse way. Lower pressure will cause load on suspension parts, premature wear on outer and inner grooves of the tires. Over inflation will make the ride bouncy and will cause tire to wear out faster in the middle so maintain correct pressure, even if you fill nitrogen gas and have tubeless tires, check the pressure every fortnight at least. When you have to do long touring, then over inflate the tire by approximately 2 psi as constant long drives causes the tires to heat up too much and will make them wear faster. Alloys check the pressure only when the tyres are cold or you have done max 3 to 4 kms before you check the air pressure. If you are doing long travels and the tires are hot, wait for 5 to 7 minutes and even then, fill the air with around 2 psi more than the normal as being hot, the tyres will show wrong air pressure reading due to air expansion, so if in cold tyres, you will fill 33 and 30 at front and rear respectively, go for 35 & 32 when the tyres are hot. When you get back, do get the air pressure corrected next morning when tyres are cold.
