Have you tried shaving your tires or having them shaved? Shaved tires last longer and have a wider contact patch than off-the-shelf tires.Smaller contact patch with higher pressures.
I quote from https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=67
"One of the reasons radial racing slicks are so effective is they feature shallow tread depths, and their contact patch acts as a single unit. However, any tread design that breaks up the contact patch into smaller elements or adds additional tread depth (required to enhance wet traction) will increase tread block squirm and reduce dry performance. This means that tires typically provide their worst wet traction and their best dry performance just before they wear out. It's also important to remember that the heat generated every time a tire is driven activates bonding agents in the rubber. As this process is repeated continually throughout the tire's life, its rubber compounds gradually harden and lose flexibility, reducing the tire's grip. Therefore, a shaved new tire will provide more traction than a tire worn to the exact same tread depth after being driven for thousands of miles on the road. "
