Getting ready to order a spare tire for my trailer, and the cheapest I have come across is one from Harbor Freight. But the one from Harbor Freight is size 4.80/4.00-12 w/4 lug wheel. The tire size I currently have on my trailer is 4.80-12 on a 4-lug wheel. What is the difference? Will the one from Harbor freight work if I blow a tire and need a spare? Would only keep it on until I get a new tire mounted back on the factory rim.
