factory tire/ wheel size 71 k10

[BurnoutNova]

i am still trying to decide which direction to go with my 71 k10. i like lifted 4x4's but kind of been likeing the factory stock 4x4's like joesjunk has.

i have the wheels i belive, i think there 15x6's but what size tire came on them? i might go with like a 2" lift and get some tall and skinny tires so it sits more like a stock k20


thanks
