Buying 18.4-28 tractor tires
18.4-28 is a rear tire for heavy utility and front-wheel-assist tractors. It is about 18.4 inches (467 mm) wide on a 28-inch wheel. It is wide enough to pull hard and carry a loader, but lower than the 18.4-30, 18.4-34 and 18.4-38 sizes that share its width, which keeps the tractor compact.
The radial equivalents are 18.4R28 and 460/85R28. A radial gives more traction and a smoother ride; bias costs less and suits loader and yard work.
Easy to confuse
- 18.4-26 vs 18.4-28: the 18.4-26 is an industrial backhoe size on a 26-inch rim. The two are not interchangeable.
- 18.4-28 vs 18.4-30: same width, different rim. Read the last number on the sidewall.
- 16.9-28 vs 18.4-28: same rim, but the 18.4 is wider and taller. Moving up from 16.9-28 needs a wider rim and more fender room.
What to check
- Tread: R-1 for field work; ask about R-4 if the tractor mostly runs a loader on hard ground.
- Ply rating: match or exceed your current tires, especially with a loader.
- Front-wheel-assist ratio: check it before changing rear size or construction.
- Used tires: ask for the tread depth, the date code and photos of both sidewalls.

How tall is the 18.4-28 tire?
The nominal overall diameter is about 59.3 in (1,506 mm), which gives a rolling circumference near 186 in (4,730 mm). That figure is an estimate that assumes an 85% aspect ratio, the usual rule for old inch sizes. 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 18.4-28 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.
