I had about 20 hrs of driving time in the past two days to debate the need to replace all of our 5er tires which all appeared in good shape with proper inflation. I was only traveling about 60 mph at the time, but who knows what the internal condition of the tire was. I know the point was made regarding the difference in cost of ST vs LT and the frequency of change. I think we need to add the 3rd variable of cost of repair due to blow out damage. Our damage appears relatively light, aluminum skirt behind tire bent severely upwards, plastic trim piece broken off along with mounting bracket, and some underside damage as we now have road debris on the floor inside the 5er. Probably $1000-2000. I was initially thinking new STs but now LTs are starting to look like a better solution, no speed limit issues, load rating is OK. Not sure I even want to keep the STs for a spare after this occurance and it's the 2nd time in 3yrs.
