Changing wheels and tire size

[Taz Master]

I have a 95 Reg cab V 6 spd long bed. HD. My book says the wheel size is a 14x5J/1.57 40 silver.
Could I run the 4X4 Reg king cab wheels which are a 15x6JJ/1.18 30 Titanium Finish
the tire size I am running is 195 75 14 . I would like to change the tire size to a 15 sense there are more available in that size. I would like to change the wheels or rims , only because I am tried of the black caps falling off all the time.

yes you casn and to keep gearing and speedometer the same google tire calculator put in old tire size and try some different ones in new tire size to get the tire you need to have same rolling circumfrence. Basically from 14 195 75 you may use a 15 inch 205 70 or 205 60 te keep the tire overall size close

205/60r15 will keep your speedo close to original and give you some spirited handling performance.
