One problem related to tire valve has been reported for the 1999 Ford F-350. The most recently reported issues are listed below.
Wife was driving in middle lane on rt95 south toward richmond, va from no-va are when left rear tire blew and absolutely nothing was hit!! tread on outter tire still in tact however outside wall was totall torn apart. Fortunately no one was killed since my wife is a excellent driver she waited for traffic to clear in right lane and was able to pull over truck (along with our 30ft camper trailer). All tires are original equip from Ford for which we special ordered on truck to ensure we had biggest tire avail as options for truck that year we ordered it. Now alum rim is ruined and Ford will not replace tire(s) nor rim. Closest firestone dealer is very far away 1. 5/2 hours. Asked sterling Ford to replace all four tires (since they no longer feel safe and show bubbles on sidewalls) and the rim but they will not even though I have bumper to bumper warranty saying that it is firestone dealer responsible. However, sterling Ford sells firestone tires but obviously doesnot warranty any of them!?!? also, about a month earlier valve stem on right rear tire went bad. . So, I have had two (2) incidents with firstone produce. Also, all tires are showing excessive tread wear and there is only 25k miles on tires. I will have to replace all tires before winter and no one can tell me how long these tires are warrantied for; 50 or 60k?? if 60k tire wears out half way and blows out on sidewall somthing is definitely wrong with these tires!!( dot number: tire size: p265/75r16 ).
