Buying 12.5/80-15.3 tires
12.5/80-15.3 is a larger implement flotation tire for trailers, balers, manure spreaders, grain wagons and heavier towed machines. It is about 12.5 inches (318 mm) wide, with a sidewall 80% of the width, on a 15.3-inch rim, for an overall diameter of roughly 35 inches. It carries more load and floats better on soft ground than the smaller 10.0/75-15.3, which fits the same rim diameter.
Moving up from 10.0/75-15.3
The 12.5/80 is wider and about five inches taller. It needs a wider 15.3-inch rim, more clearance around the wheel, and it raises the machine slightly. Check with us before switching, and change all tires on an axle together.
What to check
- Tread: I-3 traction tread is the usual choice. Ask about rib tread for machines that spend most of their time on the road.
- Ply rating: 10-ply to 14-ply is common. Heavy trailers and spreaders need the higher ratings. Match or exceed your current tires.
- Rim: 15.3-inch flotation rims are not interchangeable with 15-inch rims.
- Tube or tubeless: tell us what you run now.
- Used tires: ask for the tread depth, the date code and photos of both sidewalls.

How tall is the 12.5/80-15.3 tire?
The nominal overall diameter is about 35.3 in (897 mm), which gives a rolling circumference near 111 in (2,817 mm). That figure is worked out from the size formula (rim plus two sidewalls). Real tires vary by make and load, so treat it as a guide and use the tire diameter calculator or the lead-lag calculator before you change size on a front-wheel-assist tractor.
Is 12.5/80-15.3 a radial or a bias tire?
It is a bias-ply size. The dash in the size marks bias construction, which costs less and has stiffer sidewalls. See the radial vs bias guide.
