245/75r16 is the closest to a 30x9.50.

overall diameter of 30.30 in, and width of 9.80 in.

or 255/70r16 30.1x 10.3 in

Hope that helps I couldn't find any with a 15 in rim diameter. But it shouldn't be that much difference.

it kinda depends on what size rims you are talking about.

a 235-75-15 is pretty much the same as a 30x9.5x15 and as bnkrtstk said, a 245-75-16 is the equivelent of a 30x9.5x16

wrong. my parents had 235/75-15s on their jeep and those tires were about 1" shorter than the 245/75-16s my dad had on his 3/4 ton GMC

check the last calculator
235/75-15= 28.9"
245/75-15= 29.5"
245/75-16= 30"

265/75/15 is 30.6 That's the closest thing I can find for a 15 inch rim.

235/75s are closer to 29" than 30"s. Dad just got a set of 30x9.5 GSA's for his 95 and his 235s were probably 1.5" shorter than the 30s.
