For a G78-15 whitewall replacement, confirm the vehicle’s required tire size before choosing a modern alternative: the listed products do not identify themselves as G78-15 tires. The Travelstar UN106 is a modern radial option in two 15-inch sizes, while the Firestone is a 640-15 bias-ply tire with a narrow whitewall. The Bridgestone is a motorcycle rear tire, not a passenger-car replacement. Compare the listed size, construction, whitewall style, and intended vehicle before buying.

| Travelstar UN106, two tires | 205/70R15 radial | Buyers needing a pair in this size |
| Travelstar UN106, four tires | 215/70R15 radial | Buyers whose vehicle specifies this size |
| Firestone Classic Narrow Whitewall | 640-15 bias-ply | Classic-car owners seeking a narrow whitewall |
| Bridgestone Exedra G702 | 180/70-15 motorcycle rear tire | Motorcycle applications only |
Travelstar UN106 205/70R15 Four-Tire Set
This set includes four 205/70R15 radial passenger-car tires with an 18 mm whitewall. The product description lists four circumferential grooves for water evacuation and an M+S-rated tread for varied weather conditions. Wheels and rims are not included.
Best for: Buyers whose vehicle calls for 205/70R15 tires and who need four matching tires with a classic whitewall appearance. It was selected as the full-set option in the Travelstar size.
Limitation: The listing does not identify the tire as G78-15. Do not assume the modern size is a direct replacement without checking the vehicle’s specifications and fitment.
Travelstar UN106 205/70R15 Two-Tire Set
This two-tire set has the same listed 205/70R15 size, radial construction, and 18 mm whitewall as the four-tire Travelstar option. The manufacturer description also notes four circumferential grooves and an M+S-rated tread. The listing specifies tire only, with no wheel or rim included.
Best for: Drivers replacing two tires, provided 205/70R15 is approved for their vehicle. Choose this listing over the four-tire package when a pair is the quantity needed.
Limitation: It is still a modern radial, not a stated G78-15 tire. Verify size and vehicle requirements rather than selecting by appearance alone.
Travelstar UN106 215/70R15 Four-Tire Set
This four-tire package uses the 215/70R15 size and an 18 mm whitewall. Its listed features include radial passenger-car construction, four circumferential grooves intended to move water away, and an M+S-rated tread. The tires are sold without wheels or rims.
Best for: Buyers whose vehicle specifies 215/70R15 and who want four tires with a narrow, modern whitewall. It provides a different listed size from the 205/70R15 Travelstar choices.
Limitation: A 215/70R15 tire is not automatically interchangeable with a G78-15 tire. Check the vehicle’s tire placard or consult a qualified tire professional before selecting it.
Firestone Classic Narrow Whitewall 640-15
This Firestone is a 640-15 bias-ply tire with a narrow whitewall. Its description explains that narrow whitewalls stop before the bead, leaving a narrower band of exposed white rubber; it also describes bias-ply construction as historically used on passenger cars and light trucks through the 1970s.
Best for: Classic-car owners prioritizing bias-ply construction and a traditional narrow whitewall look. It is the clearest listed option here for a vintage-style passenger-car tire.
Limitation: The listing says 640-15, not G78-15. Confirm the exact size and vehicle fitment before purchasing; the description does not provide a stated G78-15 equivalence.
Bridgestone Exedra G702 Motorcycle Tire
The Bridgestone Exedra G702 is listed as a 180/70-15 wide-whitewall rear tire. Its features specify bias-ply construction and tube-type design. The product description says the compound and construction vary to suit the weight, horsepower, and handling characteristics of the motorcycle model it was designed for.
Best for: A motorcycle owner seeking a wide-whitewall rear tire who has confirmed this model and size suit the motorcycle. It is included because it has a whitewall and 15-inch designation, not because it is a car tire.
Limitation: This is a motorcycle tire, so do not choose it as a G78-15 passenger-car replacement.
Buying Guide: How to Choose a G78-15 Whitewall Tire
Does G78-15 mean the same thing as 205/70R15?
Not based on the supplied product information. G78-15 is a vintage-style size designation, while 205/70R15 and 215/70R15 are modern metric designations. The listed products do not provide a conversion or confirm equivalent fitment. Check the vehicle’s original specifications, current tire placard, and any guidance from a tire professional before changing sizes.
Should you choose radial or bias-ply construction?
The Travelstar options are radials; the Firestone and Bridgestone listings specify bias-ply construction. Construction type can matter for a classic vehicle’s intended setup and handling. The Bridgestone is designed for motorcycle use, so compare it only for an appropriate motorcycle application.
How wide should the whitewall be?
The Travelstar listings specify an 18 mm whitewall, while the Firestone is described as a narrow whitewall and the Bridgestone as a wide whitewall. Choose based on the vehicle’s desired appearance and the product’s correct application. Whitewall width alone does not establish tire fitment.
Should you buy two tires or four?
Choose a pair when replacing two tires and a four-tire set when replacing all four, while following vehicle and tire-professional guidance. The Travelstar 205/70R15 is listed in both quantities; the 215/70R15 option is listed as a four-tire set.
