Key Tire Specifications

This guide covers the main tire specs you need to check before choosing a spare tire.

• Width:The tire’s width in millimeters.
• Aspect Ratio:The height of the sidewall as a percentage of the width.

90	1,323	H	130

Finding Your Car’s Spare Tire Size

Knowing your car’s spare tire size helps you prepare for emergencies. The right size keeps your car safe and stable on the road.

Spare tires vary by car model and year. Use simple ways to find the correct size for your vehicle.

Checking The Owner’s Manual

Your owner’s manual has important details about your car’s spare tire size. It shows the exact tire dimensions recommended by the manufacturer.

Look in the section about tires or emergency equipment. The manual may also include instructions on how to change the spare tire safely.

Inspecting The Existing Spare

Check the spare tire already in your car. The tire sidewall has numbers that show its size. These numbers include width, aspect ratio, and rim diameter.

Make sure the spare tire is in good condition and matches the size your car needs. This helps avoid problems during use.

• Look for a code like “T125/80D16” on the tire sidewall
• “T” means temporary or compact spare tire
• The first number is the tire width in millimeters
• The second number is the aspect ratio (height to width)
• The last number is the rim diameter in inches

Many websites help find the right spare tire size. Enter your car’s make, model, and year to get correct tire options. These tools save time and reduce guesswork.

Some tools also show tire pressure and replacement tips. Always cross-check with your owner’s manual or a tire expert for safety.

Compatibility Factors To Consider

Choosing the right spare tire for your car is important for safety and performance. Not all spare tires fit every vehicle. You need to check some key compatibility factors before buying.

This guide explains the main factors to consider. It will help you find a spare tire that fits well with your car’s wheels and suspension.

Bolt Pattern Matching

The bolt pattern is the arrangement of the holes on your wheel. These holes fit the bolts on your car’s hub. If the bolt pattern does not match, the tire cannot be mounted.

Each car has a specific bolt pattern. It is written as two numbers, for example, 5×114.3. The first number shows how many bolts there are. The second number shows the distance between the bolts in millimeters.

• Count the number of bolt holes on your wheel
• Measure or find the distance between bolts
• Compare these numbers to the spare tire’s bolt pattern

Wheel Diameter And Width

Wheel diameter is the size of the wheel across the center. Width is how wide the wheel is from one edge to the other. Both must match your car’s wheels to fit properly.

If the diameter or width is wrong, the spare tire may not fit inside the wheel well. It can also affect how the tire handles and wears out.

• Check the diameter size stamped on your current tire or wheel
• Check the width size, usually in inches or millimeters
• Choose a spare with the same or very close dimensions

Offset And Backspacing

Offset is the distance between the wheel’s mounting surface and its centerline. Backspacing is the distance from the mounting surface to the back edge of the wheel. These affect where the tire sits under the car.

Proper offset and backspacing prevent the tire from rubbing against suspension parts or sticking out too far. Incorrect values can cause handling problems and damage parts.

• Find the offset number on your current wheels
• Check the backspacing if possible
• Match these numbers as closely as you can for the spare tire

Popular Spare Tire Brands
