I have 4.10's, and I just put on my 235x75x16 stockers and I was wondering what my final rear-end ratio is. I took off my heavy *** 17's and 275x60's and now I can't get traction for ****. I can smoke em' all through first and second. I even chirped 3rd gear once. Fun to drive, but when it rains.... Anyway, if anyone knows how to calculate what my gearing is, I would appreciate the help.

 

Go to smokemup.com they have a speedo calculator that will help you figure what you want to know.

 

If you had a 4.10 gear ratio with your 17's(29.99" tall), you now have about the same gear ratio since the 16" tire is only 1/10th of an inch shorter. If your still curious.. your gear ratio would be < 1% in difference with the other tires.
