Coker tires are made using old molds that the tire manufactures have used for what they consider the reliable, usable life for mass production. This doesn't mean there is anything wrong with them it's just that they are past their prime or are less reliable. These tires are made by after market manufactures probably not in the USA, but are made in their entirety as a one piece unit. Diamondback tires on the other hand are made from new molds, by the name brand manufacture producing currant first quality tires then being remanufactured by & to Diamondback's sidewall specifications hence the size and color of the stripe, much like a recap, is bonded to the sidewall of the first run tire. I have owned two sets (15s) of Coker tires with only one tire having a sidewall bubble form. The tire was quickly replaced by the dealer that sold me the tires at their expense. SO, I can not speak to Coker's end of the warranty process other than the replacement tire was shipped from them directly to me in a timely manor. I have not had any personal experience with Diamondback tires but the next set I purchase IS going to be from them. Around town I have spoke with people with mixed emotions about Coker tires, but have not heard any negative feedback on Diamondback's. That said I have not run into many people that have used Diamondback's eather. .
