Mixing G and H Load Rated Truck Tires on Same Axle
Posted by George on April 17, 2007
I seem to remember that the mixing of different ply rated medium radial truck tires was not recommended in years past. Is this still the case? If so, besides not knowing what the inside dual carrying capacity is, what other tread wear and or safety concerns are effected?
I don't think that mixing G and H load range tires would cause any significant problems. If the diameters of the tires are matched within a 1/4 inch and the tread patterns are the same or at least very similar, tire performance and wear should be fine. Structurally, the tires are similar with the higher load range tire capable of running with a highter inflation pressure that allows it to carry a higher load. When inflated to the same inflation pressure, two tires with the same or similar tread patterns should run fine.
