Quick question... what can affect the length and sustainability of the threads for your tires??? I used to use Falken tires for my 14" rims and they always got worn out after 8+ mths. So, this time around I decided to change my tires to Goodyear Ducaro 4 tires, hoping this'll lessen my need to change new tires every 8 mths. I don't race, I don't squeal my tires often, but I do sometimes take corners a lil bit on the fast side. Do you tink it could be cos my Falken tires were "softer"...
