I have heard of that, but not before 3 to 6 seasons depending on the mileage. I use the Nokians myself but have never inflated past the max pressure printed on the sidewall. In fact they always end up being about 5 psi less after you release the pump chuck. Nokian has a lot more years experience in designing and manufacturing these type of tires so that's why I go with them. I don't have enough use on mine yet to comment but time will tell. In the old days the studs were not carbide and they would wear out long before any casing wear was evident. Carbide may be different as these won't wear out unless you drag them on dry pavement and the casing may go first.
