Does anyone know how to tell what size of tires a set of chains would fit. I have a set of 4 real chains that are from my old 1985 F150. The chains are in great shape but I don't know what size tire they would fit. Thanks, Mike
One set of chains will usually fit many different sizes of tires. If they came off a truck you probably had 15 or 16 inch rims and they were probably 70 series tires. So, unless you had monster truck tires on the old truck they will probably fit on your newer vehicle.
If you are going to just try them on, it is easier to try them on your spare tire.
And if the chains fit on the spare tire then get another tire and rim and mount those chains on both tires. It is much easier to change tires in the snow than it is to wrestle chains to put them on when you are out in the snow.
