Tire Dsyfuction

I had so many issues with my rental car. This is only my second time renting a car and it is by far the most COLORFUL. One, I got the car forty minutes late due to cars not being cleaned during pickup. Next, I didn't think to ask for winter tires so I had to buy them out of pocket. Still trying to resolve that during said trip. And lastly, the tire monitor light came on for the duration of my trip. Or so I am assuming. I took to a mechanic, can't be helped due to extensive work. Asked the people at another rental place to check out so I have multiple documentation. Yet the problem persist, so I will just drive cautious and have my paperwork to explain this UNIQUE situation. No time to waste on what I can not control. I will be moving on and enjoying my trip, unless more T happens with said vehicle.
