I lost tread on BFG T/A's only months old. They would not warranty them because of the tire size to rim width.
On that particular set THEIR chart said that size would fit 6-8" wide rim. The rims were 6".
They said the rims had to be 7" in contradiction to their own charts.
Bottom line, don't expect much from BFG. It's a cheap tire.
Do a Google search for retread tires. As a teenager we used them because the treads used in recapping made them like racing slicks AND they were $21 each in Floyd's Department Store.
Now I remember also recapping Goodyear raised white letter Polyglass tires and the tire date of manufacture didn't matter.
Lots of commercial airlines use recapped tires for the planes also, so there is definitely something else going on with the significance of the quality of the tire to be recapped.
I'll also point out that there are STILL racers using 30, 40, 50 year old racing tires in vintage racing. So what's going on with this?
