In Reply to: 315/75R16 Tubes needed for '65 M37B1 posted by Mike J on Tuesday, April 27, 2004 at 0:04AM :
the 315/75r16 is a tubeless tire and there are probably no correct tubes made
1st thing you should do is make sure the
tire will work with a tube - some tires have
internal ribs which chafe the tubes - call the manufacturer (not the dealer) and find
out
a 315/75 is a 12in wide(section width when mounted on correct width wheel (what ever that may be)) has a section height of 9in
so that would make it about 34in od
a 10.00x15 radial low bed trailer tire tube might be too tall and crease (fold) when mounted and then fail. a 9.00 tube is the correct height but nowhere near enough section for the 315
tire.
options: return tires and get another set of tires
if you have to have radials then it's 9.00r16 or 11.00r16 michelin as these will work with tubes and you can get tubes (see post below)
bottom line on tubes
when you inflate the tube outside of the tire
the outside diameter of the inflated tube CANNOT be greater than the inside diameter of the tire
