Negative. I can't find that many results of a 305/35r24 on 24x12. I've only seen two but I can't see how much they stretch.
305 is a 12.0" wide tire, that is a wicked stretch and I would not run that imo. 315 is essentially a 12.50 tire so that will give you a good idea.
Edit: Here's what I found on google

Yea I personally wouldn't. But hopefully some of the lowered guys that run similar setups will chime in.
