How Can i Calculate my speed?

[F 150Cobra]

i have M5OD trans and 3.55 gears and 26.6x11.61x15 (295/50R15) tyres

in 4th going 4000 rpm whats my speed?

and in 5th at 1500 rpm whats my speed?


uhmm my speedo cable is broken the new cable is on the way but in the meantime i wanna know


oh and are the tyres to small? whats the stock tyre size?

Hmmmmmm...I think the online calculator I used doesn't account for what gear you're in because I got this

In 4th gear at 4000, I got you going 89.2 mph

In 5th gear at 1500, I got you going 33.45 mph.


I guess you need overall ratio...which I dunno.
