Continuous discharge

Q: I have a wetness problem. There is no feeling of discharging wetness nor does it flow on my leg or clothes. There is always little wetness by my private part, almost 90% of the time. Whenever I pray and after completing prayers I check and there is wetness. What is the ruling for me?

Do I have to check everytime and then make wuzu again and again? Do I need to break the salah if wetness is felt, it might be water as well since we do istinja before wuzu and offer namaz immediately. I dont break my salah, rather I complete my salah in this condition, am I doing something wrong? I am not sure whether I am a mazoor or not.

Rubbing impurity on the ground

Q: I ride scooters and bikes to school. I rolled over non-halal foods/sandwich packages with leftover foods several times when riding on the streets. I live in the U.S. and the sandwiches are subway wraps with wet food oil and sauce and certainly not halal. Hence, the bike tire becomes impure. When I ride it in rainy days, the water splashes from the tire onto my shoes and pants. Since the bike tire is impure the water splash is impure. I have to go back home and wash them every time I pray and it severely impacts my life. However, I heard that walking or rubbing impurity against the ground makes the impure shoe pure. Does this ruling apply to a bike/scooter tires? If so then the bike tire can be regarded as pure as it rubs against the ground so many times?
