Flat due to defective tire , damaged when exchanged for seasons ( not the 1st time , 2 winter tires ) , from going flat , driven on the flat tire for about a block before noticing something is off or other ? The tires have been in use for 1 year of two 6 month winters . Purchased in 2019 . May post pics of rims as well . This is related to , https://bobistheoilguy.com/forums/threads/flat-tire-discovered-tire-had.338805/ . Checked tire pressure 2 days prior and were 34 > 35 . Car was took to work by the other 1/2 the day after T.P. was checked . So , took it for granted the tires were fine the day after .Thanks
