First off, can anyone confirm if the tire racks size is the correct original? if so, this means someone swapped them for 16's at some time. Is there a simple way to tell if the are original fuchs? the tires that are on their seem to work fine, so barring any concern I'm figuring on relacing them with the same size.
I have wondered about the odometer ready, as it seems to be adding up miles quicker than I figure it should. Given the difference from stock, it will be out of calibration. I thought is if I figure out the diameter of the stock wheel, figure out the diameter of my wheels and divide the stock size by the difference I should come up how much it is out of calibration, does this sound correct? Given that stock is 15's and these are 16's I would think it adding miles slower than actual but I'll crunch the numbers and see what I come up with.
Lastly, I'm sure these topics have been discussed before. Can anyone tell me how to search the message board to find out what threads this topic may have been discussed in?
Thanks again.

Alot of people upgrade to 16 inch wheels. My 76 had 15, and I did the same thing. I would bet that most people run 205's up front, and 215 or 225 in the rear. IIRC (if i remember correctly) you had an SC model with flares, so rubbing the fenders isnt a problem for you like it is me. I would run what you have, since wider is better.
In answer to your other question about the odometer, if you have a 16, and used to have a 15, then your odometer is actually turning slower. If the axle makes 1 revolution, your 16 inch wheel actually travelled farther, but your odometer doesnt know that. I always have trouble mentally figuring that out in my head. If you had 10 inch wheels, you would go down a side street and the speedometer would register a much higher number. i could be wrong, but thats how I see it
Lastly, in the bar right under your screenname on the right hand side is a search button. You can search in any particular forum, such as engine rebuild, turboing, or tech forum. The search field should state what you are looking for, and try not to use numbers. It doesnt like them. I always have trouble searching, but if you ask nicely, most regulars who have been here a long time will respond with more information than you were hoping for. They are good
