I'm just curious if you guys have any issues with your speedometer when you compare it to GPS speed. I own my truck since 1999 and the speedometer was always off by about 5 miles when traveling at 70 it's actually 75. I've been looking into the Chrysler shop manual and this stuff doesn't give me the correct tire revolution per mile, WTF? Chrysler Shop Manual section 22. TIRES/WHEELS 22. BR/BE TIRES/WHEELS 22 - 9. SPECIFICATIONS TIRE SIZE SUPPLIER REVOLUTIONS PER MILE P225/75/R16 XL GOODYEAR 716 P245/75R16 WRT/S GOODYEAR 692 P245/75R16 LTX A/S MICHELIN 691 P265/75R16 WRT/S GOODYEAR 668 LT245/75R16 LTX A/S MICHELIN 679 LT245/75R16 LTX M/S MICHELIN 678 <--- My DODGE RAM 1999 was set to this ? LT265/75R16 LTX A/S MICHELIN 648 LT265/75R16 LTX M/S MICHELIN 652 <--- Currently running this tires and I'm still off. LT275/70R17 WGSA GOODYEAR 650 LT235/85R16 WAP GOODYEAR 650 LT235/85R16 LTX M/S MICHELIN 650 Now I have a question if you guys have any issues with your speedometer or did you calibrate your speedometer with some type of programmer (Smarty, Chrysler DRB III or Hypertech ?).
