Just recently purchased a 1990 Bronco and needed a lot of work but it runs well now, I had installed STT coopers 32 x 11.5 and the ride has improved markedly, the old tires could not be balanced evidently the former owner just ran it and did not do any maintenance on it., but I have 190,000 miles with no oil leaks since it was completely gone over by a very competent professional mechanic.
