I'll have to check again later if I can or not since I added my new gears but since I bought the truck and added my tires I have yet to make them spin, power braking wont even get them loose... But thats also one of the reasons why I went with a "sticky" tire, I didn't want to be sitting at a stop light spinning them, I wanted the grip grip

Do you know if you have some kind of traction control. If you do not have a button for it it may just be part of the pcm and just not advertised. I say this because there is no way that the advertised what 330hp or what ever it is won't spin those 20's.

oh try manually shifting as well a turning your overdrive off even though that shouldn't matter that much.

Anti spin mean the stock limited slip...my 04 Hemi w/ 3.92 lsd and 20's will spin the rears. I think the the ESP or stability control in the newer models might kill the throttle if it detects spin....my sisters z28 had that, takes all the fun out if it.

i have the 08 and i can spin them but i feel like when i do it it looses power

since we are discussing wheels, my 08 quad Hemi has stock 20"s. Can I easily put 17"s on it? or perhaps another size? What I'm getting at is I want BF Goodrich All Terrain's but for 20"s, they are $2,000.

Yes, you can go to 17 inch rims, or any size rim, as long as they have the same bolt pattern.

As for the original topic, I've got an 02 quad cab with the 4.7L, stock it was putting out 235hp, I'm guesstimating that with my mods I'm getting close to 250hp. Off the line, no, my tires don't spin, not even a chirp. I can get them to spin if I hold the brake, power to about 2k rpm and then dump the brake and punch it. Then she'll scream all the way to 2nd gear.

So I don't need to change brake rotors, calipers or anything? Just unbolt my 08's 20's and bolt on a set of 17's?

My truck is real easy to break them loose. They put down some gravel at a four-way intersection. The first day I passed by there driving normal even when I got to the gravel, and no change in throttle, and I just broke loose. It's real easy to spin them off the line. It won't hold back at all with 20" rims and the stock Goodyear HPs.

On the original topic, my 08 Ram Quad Hemi won't spin the tires on dry pavement. Mine has limited slip rear diff. Now, in gravel, loose dirt, damp pavement, etc... when I pull out in a left or right turn (as if pulling out of a parking spot), I have to be real careful or they will spin like crazy and throw gravel.
