I keep “pencils” in the tractor tool box and the glove box of my truck.Īnother type is a small specific plunger gauge with a maximum 5 PSI that is used with low pressure ATV tires. This is inexpensive, accurate, simple to use and very portable. I have a selection of tire gauges but my favourite is a pencil plunger type. If in doubt, tire dealers have charts showing the recommended tire PSI for the varying weight. The allowable variance is 10 per cent below MAX. (This is the manufacturer recommended practice.)Įach tire is labeled “MAX # PSI COLD” which is the maximum tire pressure for the maximum load at ambient temperature before engaging in use. When I do my daily walk around, before starting the unit, I check all tires. I record the tire pressure on the inside of the hood and on the rims of my tractor wheels with a permanent marker. A common agreement among manufactures is: as oil is to an engine, air is to a tire. This is not a recommended practice as once you are unstuck you now are running on an under inflated tire. The design of the R3 displaces the weight over a larger area to prevent the tire from sinking in, which is what you achieve by deflating the R1 tire. An example would be an R1 tire that is now on soft sand where an R3 should be used. If a specific tire is used outside of its designed environment, deflation may assist in its traction by displacing the weight over a larger area. Both affect the tires’ design for stopping distance, load capacity and durability. Over-inflation will cause the centre to bulge out and again, decrease the tread effectiveness by reducing the proper contact print. Under-inflation contributes to uneven and premature tire wear, overheating and tread separation. Under-inflation will distort the tire and cause the centre to be concave, decreasing its tread effectiveness and increasing its contact print. Surfaces and their “contact print” or area of the tire that contacts the surface is immediately altered by under or over-inflation. Tires are designed for specific purposes. ![]() Information about tires is moulded into the sidewall and includes the tire width, diameter, pressure, wheel size, manufacturer, manufacture date, load capacity and type (bias or radial). Tire pressure is the primary maintenance and easiest thing to check. Matching is so important now that the tractor manufacturers also recommend you match both the size and the tire manufacturer as there are small differences between manufacturers that can cause ratio damage. Mismatching the sizes can damage the drive line by changing the ratio. On 4WD tractors the same tire types are used on both axles and are size matched by the manufacturer. I own both R1, for field and primarily winter use and R3 for grounds work during the summer to reduce the contact print and allow a smoother ride. The most common are R1 (agriculture), R3 (turf) and R4 (industrial). There are three basic types of tractor tires.
