Cast away: You gotta look at it this way. The standard tire on a 14x7 Rev rim, is your basic 175/70/14. Now damage to any part of the driveline (engine, trans, wheels in this case) comes from traction, hook up, whateveryou wanna call it. With the narrow tire, you will have a severe lacking of this, that is to say, you will have no traction, therefore you will do no damage (maybe smoke the tires bald) HOWEVER, if you were to put a wider tire on, therefore gaining traction you could very well twist the spoke hub in the middle of the rim and bending or snapping spokes. So the way I see it, you have two things to look at.
#1) Using a wire rim and the traditional skinny tire will be fine, but you will not be able to use the power you have upgraded to gain. You can go fast but I'm talkign acceleration. And top speed isnt a good on the skinnies anyways.
#2) You go with a differend style rim (not spoked) and a wider tire and have the ability to use the power without bending spokes.
NOW PERSONALLY i would go with number two, because i have loked at your truck, noticed the lack of chrome, which doesnt make it very traditional style, even tho it is an older style. if you are into the small rims, which I definitly am. Then my sugestion would be a Rocket, Supreme wheel (not wire, but mag) with a wider whitewalled tire on it (possibly 205, 215 maybe?) That way, you get an old skool look (which i think would suit that particular truck more) and a way to use that power youve spent money to gain. :thumbsup:
