Volunteer Needs New Tires and Repairs

Those that know me know how badly I hate to ask for anything. I would rather go without than ever ask for help. This time, I cannot go without as it can be dangerous so here we go. I am in need of new tires for my truck that I recently became owner of. I also need to repair two of the wheels which I have been told will cost $200 for each one. The brakes are starting to squeal, and the ac line needs to be repaired as well. I am on disability and I have enough to pay for my normal expenses, but I do not have enough to cover large purchases like this. Most of the traveling I do in my vehicle is to volunteer my time to my recovery community. I do not want to have to cancel on my commitments due to vehicle limitations as I did when I was without a vehicle. Any and all help will be greatly appreciated, not only by me, but by those in my recovery family.
