[FC] Help choosing tires -my input

[N2VZD at aol.com]

i  run olds rally wheels and 185 / 70 radials on the greenbrier for a  
better ratio , and 205 / 70 14  on the lighter rampy.they  look great and handle 
fine.   the slight difference in size  can be felt!
 i played around a lot with this back a few years because i have  
powerglides in both. when i had a 4 speed in the rampy it was not as  criticle.
speedos were adjusted accordingly using a radar gun at the time , but now i 
 use a Magellan GPS on a homebrew mag mount. i bought an extra mount disk 
and  epoxied it to a hard drive magnet.
