As I recall, for large transports, BF
Goodrich is still around. I know that BF
Goodrich still exists as an aerospace company, but they sold their (automotive?) tire business to Michelin (who still sells BF
Goodrich branded tires here in the USA-popular for off-road trucks and SUV
's). No idea if the aircraft tire business was wrapped up in the sale of the tire division to Michelin or not...
planes, you have the big three: Goodyear, Michelin, and McCreary. McCreary is a specialty tire manufacturer here in the US, who also makes replacement tires for antique cars (like Ford Model T's and Model A's). They will also produce custom tires for vintage automobiles that require them. Most flight schools that I've known have favored Goodyear...not sure if that is because of durability or favorable contract terms
