Tire/Rev help on SCT X2

[BryanH]

I just went from 265/75/16's to 285/75/16's and was wondering if I need to change my revs. It seems to shift quicker into 4th and feels like a dog.
How do I figure how many I should go up, Is there a way to calculate.

I think I found it but someone chime in. 285/75/16 should be going 614.7 revs per mile.
Should I change my SCT from 500 to 614?

Try this:
Tire Size Calculator

It will get you in the ballpark!

614.7 is correct. The SCT only goes up in increments of 5 as far as user adjustability. Set it to 615
