Tire sizes

[Brooks Ellis <brooks@alpha.pr1.k12.co.us>]

    Earlier, I was asking about my wimpy tires and sideroll. Now, I am 
wondering what I would have to do to bump up my tires from the current
205/60/15's to a 205(+?)/??/16. Is it possible to do without having to 
get new rims? I would imagine that I need to also go with a wider tire to 
not screw up the spedometer. 
    Does anyone know of the WWW/HTTP 'Tire size calculator' address? That 
would probably solve half my problem.
    The car is a '90 100 Q. How hard will this feat be? Has anyone else 
done it? 

Thanks!
