Hyundai Tucson Tire Sizes by Trim and SUV Service

Hyundai builds the Tucson in several trims and powertrains, and each can ship with a different wheel size. Depending on year, wheels range from about 17 inches on base trims to 19 inches on upper and sport trims. Hybrid and plug-in versions can use sizes chosen for efficiency.

That means two Tucsons of the same year may need different tires. The correct size, load index and speed rating are on the placard in the driver's door jamb. We read that first, then check the sidewall of your current tires to confirm nothing was changed by a previous owner.

See new tires and brands for how we compare options.

Keep all four tires matched in size and model and close in tread depth. The AWD system uses a coupling that sends torque rearward when needed, and uneven tire diameters can make it work more than intended.

If one tire is damaged on a newer set, one replacement may be fine when tread depths are close. On a half-worn set, four is often the smarter buy. We measure and show you. Rotation on schedule keeps them together. See AWD vehicles.

The hybrid and plug-in versions use regenerative braking, so pads often last a long time. Parts that move less can stick, so we check caliper slides and brake fluid condition, not just pad thickness.

The 12-volt system varies by model and year. Some hybrids use a conventional 12-volt battery, and some Hyundai hybrids have used different low-voltage setups. We check what your Tucson uses before testing or replacing anything.

Plug-in owners may run the gas engine rarely. Oil still ages with time, so a time-based change matters. High-voltage battery and orange-cable repairs go to a specialist. See hybrid vehicles.

Follow Hyundai's schedule and the viscosity on the oil cap. Turbocharged engines and heavy traffic can count as severe driving. We check oil level at each visit and note seepage.

Summer puts the AC to work. A clogged cabin filter reduces airflow. Warm air usually means a refrigerant leak or a component problem. We test before recharging. See air conditioning service.

Other routine items:

• Brake pad measurement once a year
• Battery test before the hottest months
• Wiper blades before rain
• Engine air filter at each oil change inspection

Check it after new tires, after a hard pothole hit, or when you see uneven wear or an off-center steering wheel. Newer Tucsons have lane-keeping and other driver-assist features that rely on the vehicle tracking straight. If a camera or sensor may need attention after alignment work, we note it on your estimate.

We print before and after numbers so you can see what changed.

Used Tucsons come with several powertrains and tire sizes, so start by confirming exactly which version you are looking at. Then compare the tires to the placard and check the brakes, the AWD tire set and the oil history. Hybrid and plug-in models add low-voltage battery and brake slide checks.

Look up the VIN at nhtsa.gov/recalls (opens in a new tab) for open recalls. We inspect with photos and a road test through our pre-purchase inspection. It is not a warranty and cannot promise that nothing will fail later.

Match the plan to how the Tucson spends most of its miles. School runs, commuting and road trips each stress different parts. Hyundai's schedule lists normal and severe intervals, and summer heat or heavy traffic can put local driving in the severe column.

• School and errand runs: short trips age oil faster than the odometer suggests. Test the battery and measure brakes yearly.
• Freeway commuting: rotation on schedule, alignment with new tires, wiper blades before the rain.
• Road trips with cargo: pressure set for the load, roof rack hardware checked, brake pads measured before long grades.
• Light towing, where rated: confirm your Tucson's towing limit in the owner's manual, then add hitch and brake checks.
• Plug-in with mostly electric miles: time-based oil changes and a check that the gas engine runs smoothly when it does start.

We note your driving on the work order and list the next items on your invoice. See preventive maintenance for how we plan visits around your use.
