Is there such a chart that shows tire size used with a certain gear ratio as to what happens to gas milage or anything else that might be effected. Math is not may stronge suite other than 2 and 2 is four. I have not been on the forum very long, so I am not sure where to look or search if this has been covered alot in the past.

 

Check out the 335 series engine link in my sig and the 73-9 forum FAQ link in that thread. The links also have links to the calculators on this site. Or if you want a shortcut go here:

Similar to those already posted, and allows multiple variables.

ATC, that chart looks to be real performance oriented or maybe for itty-bitty engines. I would shift everything to the left three or more spaces. Is it for 4 cylinder engine applications or something, 2600RPM cruise! -WOW!??? Not even my V6 vehicles run that high. They don't even list the most common OEM ratios around 3.0...

 

Thanks for the information folks this is just what I was looking for.
