Based on what?
Are you losing adhesion? I am not. I do not buy your statement at all. I also do not cruise along at 250 watts, perhaps half of that on average. Peak crank force might be 30 pounds.
OTOH, almost all braking forces are on the front tires AND they are substantial. Rear tire wear is almost all due to rear bias. My recumbent is 52/48 and I wear front tires out slightly faster but they both get changed at the same time just to keep it simple.
