Best tire with 3.91`s

:burnout:
Looking for input on what tire to use. Currently running 26 9.50 14 with 3.91`s. Going to a 15 x 8 wheel. I have had a 27 10.5 15 on before with a 15 x 8 wheel with 3.75 back space. Very tight fit. SS springs in stock location. Inner fender lip is rolled. 318 with 904 running 13.5 with current setup. Any suggestions?
