montanass Posted December 20, 2007 Report Share Posted December 20, 2007 Just wondering who's running shorter tires on their trucks? I ordered some 20" rims fron Centerline and am planning on going with a lower tire so it doesnt look like its running on baloons. I was thinking some 275/45R20's would do the trick. also: can the PCM be flashed to correct the speedo for smaller O/D tires? OH! please post pics for those who are running smaller tires~ Thanks-Cody Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted December 20, 2007 Report Share Posted December 20, 2007 yes your PCM can be recalibrated to your new tire size specs Quote Link to comment Share on other sites More sharing options...
Quik Posted December 20, 2007 Report Share Posted December 20, 2007 305/40/20 by nitto fit on the stock sss rims. they measure 29.5 " tall could also do like you said 275/45 Quote Link to comment Share on other sites More sharing options...

drako Posted December 20, 2007 Report Share Posted December 20, 2007 Both SS_Bnoon_SS and MisterP are both running shorter tires, a good way to get rid of the gap is bring down the truck with torsion keys another inch. Quote Link to comment Share on other sites More sharing options...
