you think I can ignore the studs when factoring a wheel size? I know the best method is to measure a roll-out but I'm in bed and wanna set the computer close enough. meaning ...

- current wheel/tire = 700c x 35 w/studs (at MAX pressure)
- wheel factor setting for 700c x 32 of 2155

- think this is close enough for a ballpark until I do a roll-out?
- also how would using a factor that is smaller than the exactly correct one affect my speed and distance readings?
