What to check because bus seriously pulls to the right?

BF Goodrich is made by Michelin.
Tires are much more than big black rubber things that supports your bus. Chinese tires are me too tires-in that they make sure they look just about exactly the same as other tires we're familiar with. But who knows what the rubber compound is, tread design, belt strength, etc, etc. There is a real good reason Michelin makes 50 different tire models for trucks and buses. A carefully designed rubber compound, tread designed by testing, strong belts for every specific kind of driving from local pickup and delivery, transit bus start and stop, on/off road dump truck, on/off road logging truck, short haul, long haul, high speed highway, steering, traction, trailer, etc, etc. You couldn't give me a set of Chinese tires. Good Luck, TomC

Does it pull at low speeds? I suspect something happened at the shop when they were greasing it. Might be a worn part shifted when they lifted it - maybe something got bent . . .

More than 1 mechanic missed the bad front wheel bearing and the damage it had caused to the spindle on mine.
Symptoms were all occasional & random in presentation - slight pull, vibration, noise, & steering wheel wobble.

I found it by jacking up the front of the bus & giving each wheel a spin. One was silent, one had a slight noise - $$$ later, I had installed a new steering knuckle, wheel bearings, kingpin & bushings.

Hope they are able to determine the true cause.

Firestone makes good truck tires too. The FS560s that came on my coach are very smooth riding tires & have held up well inspite of my curb bashing.

Well did tires and alignment fix it? (expiring minds would like to know!)

It's a real good tip, Kyle4501 mentioned in jacking.  I think this is key and how I was instructed to do for any wheel components, and drilled in for any brake adjustment. I can see  a same pattern though just as earlier with cars and the smaller likes of inspections. So smartly using these now more affordable jacks like 4 or 6 wheel jacks as a system lift. Anyway I could bore everyone going on but many components need to be free from load to inspect and adjust properly. It sure helps the lubrication of components having no load so the extremely small clearence can get greased.
