Hi,

I have Nitto NT 255/45 on the front and Nitto 275/40 on the rear, I know the revs per mile are 770 front and 781 rear, but the SCT only allows you to set one setting. How do I know what the revs per setting should be? Is there a website or calculator out there that will figure it out for me or does anyone know what it would be or how to figure it out????

Please let me know. Thanks

I think it only has increments of 5 anyway, so I would just split the difference and set it to 775.

I'm pretty sure only the rear matters since that's where the sensors read.

 

i just ordered 275/40 nittos for the rear also... how would i change it with the sct2?

there are speed sensors in the rear, and none in the front...that makes me think it doesn't care what speed the front wheels spin at [img]style_emoticons/<#EMO_DIR#>/eek.gif[/img] [img]style_emoticons/<#EMO_DIR#>/biggrinjester.gif[/img]

 

Thanks guys [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img] guess i'll just use the rear rev per mile setting and set it to 780 [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

When you go to flash you car it will ask you if you want to specify optional settings answer YES and scroll through each option until you get to rev/per mile [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

Hope this helps

 

17" or 18" ?
786 = 17 756=18"

Here is a real nice site for figuring it out. And comparing sizes
