Does anyone make a 31/9.50-15 or equivalant metric tire?
Preferably a All terrain or mud terrain. Thanks and
Happy Trails!

Is 30" too small? ( http://www.discounttire.com/mega-bin/megajen?tem=san.tires-3.tem&car.value=006021&product.value=30&product.value1=950&product.value2=15&year.value=1994&price.table=UTSINT )
