1991 Buick Roadmaster Sedan Spare Tire
1991 Buick Roadmaster Sedan models require a 5x5" (5x127mm) wheel and spare tire size that EZ Spare does not produce.
We've provided (spare tire only) fitment options below, but a spare wheel with the correct diameter, width, offset, bolt pattern, and hub size would be needed separately.
A spare wheel might be found at a used parts store from the same vehicle type.
Another more DIY approach would be to find a wheel from another vehicle with matching wheel specifications.
