Mt s/s revs per mile

[stealthfrc]

Anyone know the revs per mile number for the Mickey Thompson s/s 305/35/19's ? Having a hard time locating it and before doing the math want to see if anyone just has it available?

Did ou even bother to search on their website? I found that in less than a minute.

Of course I did bud? I found the same thing in the same amount of time. What you fail to realize is the 27.8 is not listed. They have 27.5 and 28, also the tire circ is not listed the same. ALSO, there are 2 different websites that say the tires are 2 different heights. One says 27.8 the other says 27.4. I'd like my speedo accurate, not "close"
Thanks for nothing.

Anyone else have any helpful info they can share? One that has actually entered a number into the flare tool and checked their speedo with a Gps?

You realize the difference is only .3'' right? That is only going to be off by a few revolutions per mile, not a big deal at all. But since you want to complain and act like a child, here is some common sense math.

There are 63,360'' in one mile. The overall circumference, meaning the over length of tire if laid out flat, is 87.3''. Now divide 63,360 by 87.3 and you get 725.77. So round that up to 726, or round it down to 725, and that's the amount of revolutions per mile.

YOU'RE WELCOME.

If you go by the 27.4'' overall diameter, revolutions per mile with be 735.

If you're adjusting the revs per mile with the whipple tool, you'll kinda have to guess it. When you change it, set your cruise control to 30mph, and verify with a gps speedo (you can use your phone), and you can fine tune from there.

I say this, because I did the calculations and put it in, and my speedo was way inaccurate. Also the stock revs per mile didn't match the calculations I had for a 27" tire either, so I dunno.

I forget what I put in, but it's accurate to within 1mph now, which is close enough for me.

For anyone curious I had some on Facebook say 736, I put that in and it's about 1mph off so I'd say pretty close

1 mph wont be a big deal
