SPORTYOUTH’s 4.10\/3.50-4 inner tubes are a direct-fit solution for 4\" rims (10\" overall diameter) and come as a convenient two-pack. Built from thicker rubber than ordinary tubes and fitted with a TR-87 bent valve stem, these tubes are intended for lawn equipment, hand trucks, garden tractors, wheelbarrows, generators, and similar applications around the yard or jobsite.\u003c\/p\u003e\n\n\u003ch3\u003eWhat size and valve type do these tubes use?\u003c\/h3\u003e\n\u003cp\u003eThese inner tubes are marked 4.10\/3.50-4 and are made for 4\" rim diameter tires (commonly listed as 4.10x3.50-4 and several similar notations).
