Yes, a 215/55/17 is slightly shorter than the stock tires size. The actual 17" size for a stock height truck would be 225/55/17.
Keep in mind almost nobody on here is stock height, so nobody runs that tire - lots run a 205/40/17 but currently I have 215/35/17 in front with a 265/35/18 rear (going to a 245/35/18)
As long as your rims are the correct offset you should be fine with 215/55/17 as it is almost the identical dimensions as stock.
