some new used rims

[fiero_fighter]

picked up some used rims today, working on getting more grip on takeoffs..

Against popular trends I stayed with a 15" rim, a nice simple black 5 spoke.  Still only a 7" width, but I'm saving a ton of weight(10.8lbs a rim) so I can move up in tire size, what I'd like is some input on tires you guys have used.

out back I'd like to try 255/60's  thoughts? 
205-225 in front to help correct steering issues.

I have a set of 275/60's, but thats just overkill, and dangerous on 15x7's
