I found my '70 last spring with good bones and bad rims. With a Classic Car “emporium” and shop right down the road, I put a set of old Keystones on it. I knew the tires that came with the car where newer than the ones on the Keystones but in my excitement, I ignored this small detail and hit the road, feeling ok that they “passed”
inspection. Well, last month, I paid the price. Rear driver’s side tread peeled off tire at about 75MPH and the sound was almost as terrifying as the result. Ouch. I will get new panel in the spring but could not have it sit over the winter in such a state so patched it up for now (and put new tires on it). Still makes me cringe…thanks for reading.
Ouch! Only solace I can give you is dynacorn just released ‘70 quarters. You can cut a patch from those should you need it. They’re more accurate than other 1/4s or patch panels on the market.
This happened on my passenger rear coming home from work on the freeway on the '67 I owned back in 93. By the time I made it to the shoulder the entire wheel well was tubbed and the quarter was destroyed. Back then it cost more to fix it than the car was worth, so I sold it. Dry rot happens from the inside, so never trust an old tire on your vintage car.
So sorry and certainly not trying to judge. I just wanted to make sure that other readers who haven’t been through what we went through know before hand. I had no idea until I heard the dreaded “WHOMP WHOMP WHOMP” and that was that.
