318/44R24 Tires
On a 318/44R24 tire, 318 is the section width in millimetres. 44 is the aspect ratio: the sidewall stands 44% of that width, or 140 mm tall. The R means radial construction. 24 is the wheel diameter in inches — 610 mm. Add two sidewalls to that rim and the tire measures about 889 mm across, or 35.0 inches.

318/44R24 — frequently asked questions
What do the numbers in 318/44R24 mean?
On a 318/44R24 tire, 318 is the section width in millimetres. 44 is the aspect ratio: the sidewall stands 44% of that width, or 140 mm tall. The R means radial construction. 24 is the wheel diameter in inches — 610 mm. Add two sidewalls to that rim and the tire measures about 889 mm across, or 35.0 inches.
How else is 318/44R24 written?
318/44R24 is also written 318 44 24, 3184424 or 318-44-24, and on a P-metric sidewall as P318/44R24. Some high-performance fitments stamp it 318/44ZR24 — the ZR there is a speed-rating marking, not a different size. All of them describe the same section width, aspect ratio and rim diameter, and any of them typed into our search lands on this page.
Which load index and speed rating should I pick for 318/44R24?
The 318/44R24 tires we have in stock run load index 116 (1250 kg) with speed rating Q (160 km/h). Match or beat the two figures on your vehicle's tire placard — usually on the driver's door jamb, sometimes inside the fuel filler flap. Going below the placard's load index or speed rating is unsafe; going above it is fine.
Can I fit a different size instead of 318/44R24?
Stay with the size on your placard unless a tire professional has signed off on an alternative. A workable substitute keeps the overall diameter within roughly 3% of 889 mm, carries at least the same load index and speed rating, suits the rim width you actually have, and clears the suspension and bodywork at full lock. Speedometer, odometer, ABS and stability control all calibrate off rolling diameter, so this is not a swap to make from a chart alone.
Are 318/44R24 tires legal for winter in Québec?
Québec requires winter tires from 1 December to 15 March, and the tire has to carry the three-peak mountain snowflake (3PMSF) pictograph or be studded — an M+S marking on its own does not comply, and fines run $200 to $300. We do not stock a 3PMSF-certified tire in 318/44R24 today, so nothing on this page meets that mandate. Email us and we'll check what the distributor has coming.
Do you install the tires?
No. We are delivery only — your 318/44R24 tires ship to your door anywhere in Canada, and we do not mount, balance or install. Take them to any shop, or fit them yourself.
Do I have to buy four?
No. Prices on this page are per tire, and the button on each card adds a set of four because that is the usual replacement. Order whatever quantity you need. If you are replacing only two, fit them on the same axle so grip stays balanced side to side.
Fitment guidance here is general. Your vehicle's tire placard and owner's manual are the authority, and a tire professional should confirm anything that departs from them.
