New tires but not wheels

I just received new Carlisle 225 / 75 r 'E' rated 15 in tires from discount tires direct, but I absolutely can't find 2600 lb. dexstar 8 spoke white wheels any where.I have contacted at least ten co.s and 2050 lbs. has been the highest weighted wheel any one had.My factory wheels were 2650. 14 in.. How about some suggestions out there,
