I put a program together so I would know the speed of each gear with 13.6 - 14.9 - 16.9 - 18.4 tire sizes. Here is what I come up with.

RPM 13.6 14.9 16.9 18.4 1115 Circum 180 190 198 206 Diam 57.30 60.48 63.03 65.57 Rev/Mi 352.00 333.47 320.00 307.57 Speed 1 2.841257 2.999104 3.125382 3.251661 2 4.026724 4.250431 4.429397 4.608362 3 5.261587 5.553897 5.787745 6.021594 4 7.456897 7.871169 8.202587 8.534004 5 10.10225 10.66348 11.11247 11.56146 6 14.31724 15.11264 15.74897 16.38529
