ON Waterfox and Edge I can't see the tire size calculator. Message says 'Need a Plug In' but it doesn't say which one.

Help? Which One? Thanks

Google works for me

I know. I know. There are other calculators out there. But using the Official 914 Calculator. What's not to trust ??

Hey Bill, IIRC the 914 calculator hasn't worked for a few years now due to some problem with the plug-in.

Try one of these, & use 165/80R15 as the baseline 914 tire size....

Thanks Tom!

I wrote this one years ago, it already has the 914 gear set available in the pulldown menu, and produces a chart of speeds in each gear. It requires the Java plugin. There is a help page available to explain how to use it.

Gear and Tire Calculator

The 914 tire size calculator works just fine and has for the last 15 years or so.



Since it hasn't been updated in forever, some browsers will complain but you can still add an exception for 914world and it will run just fine.

It uses Java, so make sure you have the latest version installed. Then go to your Java control panel and under "Security" add:
http://www.914world.com
to the "Exception Site List"

Restart your browser and it should prompt you to run the applet the next time you go to the page.
