I have a 2009 Versa sedan, base model, which comes with 14" wheels. I currently have 185/65R14 tires, and I'm looking for new winter tires and rims, but I can't find anywhere with 14" rims in stock.

Can I just upgrade to 15" rims and get tires with a smaller aspect ratio (something like 185/60R15) so the new wheels have the same outside diameter? Would the speedometer be affected?

Rim & Tire Size CalculatorSee how changing your tire size affects your car’s performance
×
Our wheel size calculator is the most comprehensive tire comparison tool suitable for passenger cars, SUVs, and Vans.
Key features:
  • - Comparison between two tire (tyres) sizes, either can be metric or imperial (US)
  • - List of possible tire equivalents and alternatives
  • - Option to change suspension parameters (fender clearance, scrub radius, suspension clearance, wheel well clearance)
  • - Car Performance option: find out how changing your tire size affects your car’s performance using text explanations
  • - Tire Plus / Minus sizing option
  • - The ability to use only those tire sizes that are on sale. Non-existent tire sizes will not be offered for selection
  • - Using Tire Designations: ISO Metric, LT High Flotation
Note:Dimensions displayed are calculated using industry-standard tire sizing specifications:
  • • ISO 4000-1, ISO 4000-2 Passenger car tyres and rims / Tyres / Rims
  • • ISO 8855 Road vehicles / Vehicle dynamics and road-holding ability

Performance Consequences
DESIGN
⬈ Improve

Improved aesthetics. Larger discs and wider tires, as a rule, improve the visible appearance of your vehicle.
ROAD HOLDING ABILITY
⬈ Improve

Increasing the rim diameter makes it possible to accommodate larger car brake discs and calipers with a greater number of pistons. Such additions significantly improve the effectiveness of a car's braking system.
PRECISION OF STEERING RESPONSE
⬈ Improve

Improved steering response and behavior on turns. For example, an increased rim diameter, combined with a smaller tire height, will improve the car's stability on corners, as well as increasing the speed such corners can be safely undertaken.
GRIP ON DRY PAVEMENT

GRIP ON WET PAVEMENT
No changes


GRIP ON DIRTY SURFACES
No changes


HYDROPLANING RESISTANCE
⬊ Worsen

Reduced hydroplaning resistance. A lower and wider tire creates a larger contact area with the road surface. This increases the quantity of water that the tread needs to expel from beneath the wheel. Tire makers try to counteract this by using directional treads or, as is becoming increasingly more common, asymmetric treads, in which two halves of the tread can be designed independently of each other, so as to fulfill different requirements.
RIDE COMFORT AND NOISE
⬊ Worsen

Low riding comfort. Reducing the tire height makes traveling less comfortable than on tires with a higher profile.
FUEL CONSUMPTION
No changes


TREADWEAR
No changes


COST
⬈ Increase

Smaller diameter wheels and taller tires are less expensive than larger diameter wheels and low profile tires.
WEIGHT
⬈ Increase

Generally speaking, wheel weight becomes a part of your vehicle's overall weight. Cars that are lighter will have an easier time picking up speed and are easier to slow down when needed. It also has a positive effect on overall fuel consumption.

Factory 15 tires are P186/65/15
There is a 16 inch option as well. Those are p195/55/16.
You can find factory wheels at any junkyard fairly cheap, or you can also look at www.car-part.com too.
