See - Bigger tyres are generally heavier. But as you considering a slight jump from 15 Inch to 16 Inch - it may not have a significant impact - but yes a minor variation could be observed in Pick up & Mileage

> Though City Vtec has descent power output - but choosing bigger tyres (which are slight heavier too ) can impact a minor pickup difference - especially on first 0 - 30 kms speed and may come in notice during city driving

> Your mileage can come down by 5 - 7%. For ex - if you getting a mileage of 14 Kmpl - post bigger wheels you can expect it drop to 13 Kmpl

For shockers & suspension - i dont really foresee any kind of negative impact by upgrading it from 15 Inch to 16 Inch - but its always advisable to buy tyres as per recommended size stated by Manufacturer in consumer manual.. It not only gives best performance but also the optimum life to suspension, shockers, mileage & performance of vehicle.

Yes - thats a recommended size - if you considering 16 Inch Alloys (but not for Indian market, but for International market)

Honda is offering 16 Inch Alloys in other Asian markets in Honda City (having lower ground clearance)
Been you reducing height (from 65 to 55) considerably and width not increasing considerably- it may still reduce in the ground clearance

Remember
Any Kind of Tyre Upgrade if done should be done with max 3% variation either up or down - else the fuel efficiency and other factors can actually impact the car

How is this calculation done

Existing Tyre
R15 175/65 Tyre

Wheel diameter: 15 inches, 15 inch × 2.54 cm = 38.1 cm
Sidewall Gap: (.65 * 17.5) * 2 = 22.75 cm (for both Sidewalls)

Total Diameter Reqd = 38.1 cm + 22.75 cm = 60.9 cm (approx)

New Tyre - Upgrading Size
R 16 185/55 tyre
In 16 Inch > Wheel diameter: 16 inch × 2.54 cm = 40.65 cm
Sidewall Gap in 16 Inch: (18.5 * 0.55) * 2 = 20.35 cm

Diameter in 16 Inch: 40.65 cm + 20.35 cm = 60.9 cm

This the Tyre though seems compatible - but the height is getting reduced and may impact ground clearance

If you choose in R15,195/60
Wheel diameter: 15 inches, 15 inch × 2.54 cm = 38.1 cm
Sidewall Gap: (.6 * 19.5) * 2 = 23.4 cm (for both Sidewalls)

Total Diameter Reqd = 38.1 cm + 23.4 cm = 61.5 cm (approx)

It will fall within desired variation but can give much better impact.
So I will say - stick with 15 Inch only - but may buy tyres with a better size of R15,195/60 - you may yes observe a slight reduction in fuel efficiency as what mentioned originally - but will definite make difference for the purpose of bigger, wider wheels. With 16 Inch - you may also be required to change RIM of the vehicle which other-wise wont be required with 15 Inch Wheels

@ Rish,

The states tyres R 205/60 in 17 Inch Alloys are not the correct fit.
> Its wider and will scrape in wheel well
> will distort in Handling, Drive-ability
> Impact Suspension, Steering Dynamics
> ABS will not be effective

The size is complete mismatch and not recommended for Honda City

Tyres need to be replaced in if upsizing wheels
The same can not be fitted in the same.
