I had BFG ta kd tires 245/40/18 and 285/30/18 for 2 month. Air pressure always drop to about 20psi from 40psi in a week or 2. What can possible cause this? I know my area's road condition is pretty bad but it shouldnt cause tire to go flat. There are no dmg on the tires(i assume) and they are almost brand new too(i bought them brand new). Is this a characterist of low profile tires? Can it be my suspension(i have stock suspension)? I dont think its my aligment cuz i just had it done a month ago. HELP GUYS

take your tire to a professionla tire shop, have them check the air stem (the thing you put air into), sometimes that stem goes bad and you got yourself a slow leak. also, if your rim is bent, it will also leak air.
