The closest listed match to a T125/70D15 spare is the Continental sContact T125/70R15, but its R designation means it is not an exact D-designation match. Confirm the tire size, construction, load and speed requirements in your owner’s manual or on the vehicle placard before buying. The other spare tires below are different diameters, while the Starfire is a regular-size tire rather than a compact spare. This guide compares the listed options so you can identify which, if any, suits your vehicle.
| Product | Listed size | Best suited for |
|---|---|---|
| Continental sContact | T125/70R15 | Drivers whose vehicle specifies this R15 spare |
| Falken FK-090 | T125/70D17 | Drivers who need the listed 17-inch spare size |
| Continental Spare | 125/70R16 | Drivers whose fitment calls for a 16-inch spare |
| Continental sContact | T125/70R16 | Drivers who need the listed R16 temporary spare |
| Starfire Solarus AS | 215/70R15 | Drivers shopping for a regular all-season tire, not a compact spare |
Continental sContact T125/70R15 Spare
This is the closest listed size to a T125/70D15 spare: it is a temporary spare with a 125/70 profile and 15-inch rim designation. However, the listing uses R, not D. Do not assume the construction is interchangeable; verify the vehicle’s specified spare size and construction before choosing it.
Continental describes wide grooves and open shoulders that move water away from the tread, plus angled tread blocks and sipes intended to improve grip in dry, wet, and light winter conditions. It is best for a driver whose vehicle documentation calls for this specific R15 temporary spare. Its stated temporary-spare use is a limitation: it is not presented as a regular replacement tire.
Falken FK-090 T125/70D17 Spare
The Falken FK-090 is listed as T125/70D17, so its 17-inch designation differs from a D15 target. It may suit a vehicle that specifies this 17-inch size, but it is not a direct size match for a 15-inch spare. The supplied product details also give package dimensions of 27 by 27 by 8 inches and a package weight of 8.7 pounds.
Choose this only if the vehicle’s required spare size matches the listing. The provided features do not describe tread performance or specify vehicle fitment, so confirm those details independently. Its key limitation for this search is the 17-inch size.
Continental 125/70R16 Spare Tire
This Continental tire is listed as 125/70R16 and described as all-season, fuel-efficient, and intended for a commercial van. It is best for buyers whose vehicle calls for a 16-inch tire with those listed characteristics. The R16 designation does not match a D15 spare, so it should not be treated as a substitute based only on the similar 125/70 numbers.
The listing’s commercial-van description is important when checking intended application. Confirm the vehicle’s manual, required load capacity, and wheel size. The product information provided does not specify temporary-spare use, so buyers should not assume it is a compact spare.
Continental sContact T125/70R16 Spare
This Continental sContact is a temporary spare for passenger vehicles, listed as T125/70R16 with a 96M designation. Its tread features wide grooves and open shoulders for water evacuation, along with angled blocks and sipes intended to support grip in dry, wet, and light winter weather.
It is best for a passenger-vehicle owner whose specified spare is this R16 size and rating. Compared with the R15 sContact, the main listed difference is the rim diameter. Its limitation is that it does not match a 15-inch spare requirement; verify the exact specification before purchase.
Starfire Solarus AS 215/70R15 Tire
The Starfire Solarus AS is a 215/70R15 all-season tire, not a T125/70 compact spare. Its listed features include deep lateral shoulder grooves, an all-season tread compound and profile, and a smooth ride with controlled handling.
It is best for someone seeking a regular all-season tire in the listed 215/70R15 size. It was included as a limited alternative for readers comparing 15-inch tires, but its width and intended use make it unsuitable as a direct T125/70D15 spare replacement. Avoid choosing it as a compact spare unless the vehicle manufacturer specifically approves that size and use.
Buying Guide: How To Choose A T125/70D15 Spare
Does T125/70R15 match T125/70D15?
Not automatically. The size markings differ in construction designation: the product listing uses R, while the search term uses D. Check the owner’s manual, vehicle placard, or tire professional’s guidance to determine the required tire type. Do not rely on similar numbers alone.
What should you verify before ordering?
- Full size: Confirm the complete size, including the final rim-diameter number.
- Construction: Match the specified D or R designation where required.
- Load and speed markings: Check that the tire meets the vehicle’s stated requirements.
- Spare type: Confirm whether the vehicle requires a temporary spare or a regular tire.
- Wheel fit: Make sure the tire is appropriate for the spare wheel and vehicle.
The products listed here include 15-, 16-, and 17-inch options. A different rim diameter is a meaningful fitment difference, not a minor variation. If the exact T125/70D15 size is required, none of the listings is an exact match by its stated size.
