Gear RPM calculation?

I need to know what rpm my car would be turning in third gear with a 3.42 gear and 26inch tall tire vs. 3.73 with a 26inch tall tire at around 125 to 130 mph. let me know I need to get some gears ordered soon

check out Richmond Gear's website. they have a great gear calculator that should give you the info you need. keep in mind that the tire doesn't always measure what the sidewall says it is. usually a bit shorter.
