This has probably been asked before but search didn't help me...


Ok I know when you put bigger tires on it makes your speedo off...


But when you put bigger tires on does that mean your rpm drops a little? Not off, but say your going 70 and instead of being at 3000RPM it willl be at like 2800RPM? Is this true or not?

 

If you compare the speedo (which you know is wrong) to the tach, they would be the same. Now, at 70mph true speed, your tach would be lower with larger tires.

 

Ok thank you toy283
