How to Know If My Tires Need Change

Visible Damage - Bubble, cuts, punctures, or holes

Where Can I Find My Tire Size and Details


Tire sidewall:
Look for a code like "265/70R17 115T" - this indicates width (265mm), aspect ratio "compared to width" (70%), rim diameter (17 in

ches), load index (115), and speed rating (T).

Driver's door jamb: A sticker showing recommended tire sizes and pressures.

Owner's manual: Lists all approved tire sizes for your vehicle

How to Choose the Right Tire for My Car



Selecting the perfect tire depends on several factors:

Vehicle compatibility: Always match the tire specifications of your car

Driving conditions: Consider your typical weather (summer, winter, all-season)

Driving style: Performance tires for spirited driving, touring tires for comfort

Budget: Balance quality with cost - premium tires often last longer

Mileage warranty: Check the treadwear rating and manufacturer warranty

Fuel efficiency: Low rolling resistance tires can improve fuel economy

Things to Keep in Mind Before Switching to Off-Road Tires

Off-road tires offer great capability but come with trade-offs:

Noise level: Aggressive tread patterns create more road noise on pavement

Fuel consumption: Heavier construction and increased rolling resistance reduce fuel economy

On-road handling: May feel less responsive on paved roads compared to highway tires

Ride comfort: Stiffer sidewalls can result in a firmer ride

Tread life: Softer compounds wear faster on pavement

Size considerations: Larger tires may require lift kits or modifications

Speedometer accuracy: Different tire diameter affects speedometer readings

Warranty: Some modifications may affect vehicle warranty

The Meaning of Key Tire Numbers


Understanding tire numbers helps you choose the right replacement. Here's what each number means in a tire size like "245/40R18 93W":

245 - Tire width in millimeters from sidewall to sidewall

40 - Aspect ratio (the tire's height as a percentage of its width)

R - Construction type (R = Radial, the most common type)

18 - Wheel diameter in inches that the tire fits

93 - Load index (indicates maximum weight the tire can carry)

W - Speed rating (maximum safe speed: W = 270 km/h)

Additional markings you might see:

M+S or M/S - Mud and Snow (all-season capability)

Three-Peak Mountain Snowflake - Certified for severe winter conditions

DOT code - Manufacturing date and plant information
