Hey guys i got a quick question. When i bought my used 95 GMC Sierra 4x4 it came with two sets of tires on rims, one size that is currently on the truck now is 265/75/R16 and the other set is 235/75/R15. Now, when i look on the inside door jam of the truck for the tire information it says my standard size should be 225/75/R16. Basically my question is with the wider tires i have on the truck now ( 265/75R16 ), would it throw the speedometer off at all..? And if so how much are we talking about roughly..? Would it register faster speeds then I'm actually going or slower...? By the way my speedometer is in KPH not MPH. Any help is greatly appreciated.
