Well ya see EL, if ya had new tires then ya might be too overconfident and you could possibly drive a little too fast and that would be dangerous. If ya know yer tires are bad, then you'll drive slower and in turn, safer. LMFAO !! Plus, just like the rubber goods(blankets,hoses, gloves and sleeves) being tested less and less because THAT costs money. Now why should we go above and beyond OSHA rules like we always have? If it's good enough for OSHA it's good enough for FE. Just like the tires. If it's good enough for PA, it's good enough for FE. Them things cost money ya know !!!!
