general grabber uhp, there goin on a 2007 dodge ram 4x4 qc
tire size is 305/40/R24(it says the diameter is 33"), and also how many inches is the stock tire?

 

I can't state for sure that they will fit. If your stocks are on 20 in rims, I believe they are like 32.9 in. Anyone can correct me if I am wrong. It sounds like they will fit if the overall diameter is the same. Only makes sense. Sorry, not more help.

math on stock size (275/60-20) works out to 33" tire. your new 33"s should fit fine in the well, you might get just a little bit of rub when you lock the steering in one direction or the other if the backspacing isn't right.
but a little bit of rubbing at full turn won't really hurt anything since you're only going 2 mph when you do that. look into a front level kit to solve the rub if it does.

 

thanks for the help ill post some pics im picking them up tommorw

 

Same diameter, but you would be going from a stock width of 10.8 inches up to 12" wide. With the right backspace, you will be fine with no rubing.
