Definitions has changed to Section 3.1. ScopeThis SAE Standard applies to the usage of tires of the same nominal size and
5、 tread type, but withdifferent outside diameter for articulated front-end loaders. Articulated four-wheel-drive front-end loaderperformance and component life can be affected by excessive differences in the tire outside circumferenceand/or diameter. The purpose is to provide specific guidelines for
6、the usage of tires with different outsidecircumference and/or diameter on articulated front-end loaders.2.

Definitions3.1 Overall Diameter (OD)Largest dimension of the tire extremities measured at the tire centerline. Thismeasurement should
8、 be taken in an unloaded and inflated condition.3.2 CircumferenceDistance around outside of tire measured at the centerline of tread. This measurementshould be taken in an unloaded and inflated condition.4. Field of ApplicationAll four tires must be the same nominal size. This will minimize tire dim
9、ensionaldifferences. Tires of different construction type (e.g., radial, bias, or bias belted) may be used on differentaxles, but both tires on the same axle must be of the same construction type. This document pertains tostandard configured articulated loaders only. If articulated loader is equippe
10、d with no-spin differential or tirechains, consult the articulated loader manufacturer.SAE J2204 Issued MAY94-2-5. Determining Tire Match5.1 Tire circumference/diameter on the same axle must be within 3% of each other. Tire circumference/diameterbetween front axle set and rear axle set must be withi
11、n 6% of each other.5.2 Procedure for verifying dimensional correctness of four tires on an articulated loader:5.2.1 Measure all four tires, inflated to their proper working pressures.5.2.2 Left front must equal right front, 3%.5.2.3 Left rear must equal right rear, 3%.5.2.4 Left front and right fron
12、t average must equal left rear and right rear average, 6%.5.3 Procedure for determining acceptable dimensional range for a replacement tire on an articulated loader:5.3.1 Measure the three tires remaining on the loader, inflated to their proper working pressures.5.3.2 The replacement tire, inflated
13、to its proper working pressure, must equal the tire remaining on the axle (onwhich it is to be mounted), 3%.5.3.3 Left front and right front average must equal left rear and right rear average, 6% (same requirement as5.2.4).5.3.4 Mount the replacement tire on a wheel and inflate to the recommended i
14、nflation pressure. Measure thecircumference/diameter of this tire and wheel assembly. The circumference/diameter should be within the3% tolerance for mating tire on the same axle (5.3.2) and the 6% tolerance for front to rear axle set (5.3.3).PREPARED BY THE SAE OFF-ROAD MACHINERY TECHNICAL COMMITTE
