710/70R42 Tractor Tires

Buying 710/70R42 tractor tires

710/70R42 is a very wide radial rear tire for high-horsepower tractors. It is 710 mm (about 28 inches) wide, with a sidewall 70% of the width, on a 42-inch rim, for an overall diameter of roughly 81 inches. Tires this wide spread the tractor’s weight over a large footprint, so they pull hard with less soil compaction. On some farms a single 710 replaces a set of narrower duals.

This size is usually built with R-1W tread for traction in heavy and wet soil. It is also made in IF (increased flexion) and VF (very high flexion) versions, which carry the same load at lower pressure. Those cost more and pay off where compaction is a concern. See our flotation tires for other low-pressure options.

What to check

• Rim: a 710/70R42 needs a wide 42-inch wheel. If you are moving up from a narrower tire, you will likely need new wheels. Ask us about wheels.
• Road width: wide singles can take the tractor past legal transport widths in some areas. Check before you order.
• Load index: match or exceed your current tires. Standard, IF and VF tires of the same size have different pressure tables.
• Used tires: these are expensive new, so good used tires are in demand. Ask for the tread depth, the date code and photos of the bead area.

How tall is the 710/70R42 tire?

The nominal overall diameter is about 81.1 in (2,061 mm), which gives a rolling circumference near 255 in (6,474 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 710/70R42 a radial or a bias tire?

It is a radial. The R in the size marks radial construction, and radials need careful pressure setting. See the radial vs bias guide.
