I'm in need of original type tires. Coker shows 7.00 x 15 but doesn't give many details- I know it's a Firestone road tire, blackwall. Anyone ever buy these? Also, are inner tubes with a 45 degree valve stem available? My truck is a 49 3600 with original split rims. Please, before someone replies telling me to get rid of them and get radials... don't- truck must be original. Thanks
