Firestone Transforce HT2 LT235/85R16 E Ply Tire

Not a bad tire but after I purchased them I notice 2 of the 7 I bought for my Dually code dates were 1822 which makes them 2 years old already and the other 5 were 3823 which make them 1 1/2 years old. I got these at Americas Tires and they told me they were shipped from Firestone with those code. I was not too happy but they already ran my card before I found out they were that old.

I have a 2001 F350 dump truck with 3800 original miles. I replaced the factory tires that were 22 years old with these. Poor choice on my end. These tires follow road crown so badly that it is not even safe. I adjusted the alignment for proper caster to compensate for road crown to no fix. I played with numerous tire pressures but they still follow road crown. If you let go of the steering wheel the truck will go off the road to the white line. Keep in mind the alignment is proper for the road crown. I am convinced these tires are just too soft for any vehicles with weight even though these meet factory specs. The other tires you could let go of the steering wheel and the truck would go straight. I will need to replace these even though I just bought them because it is a major safety concern.
