well what gears are you going to be running, with 3.55's and 28's you'll bog BAD at the line.....I had 3.55's on my solid axle with 10.5 by 26 15's on the back of my 99 and I had no problems at bit, 6500 RPM off the line with no spin whatsoever! so I'd think if you go with a 26 you could go a little wider and it won't hurt you off the line like a 28 will. just my .02 now if your going to be running like 4.10 or 4.30 or bigger, I'd say it would probably be ok....
