Okay, already posted to your thread on the Delphi boards, but will post a general reply here for some of the other posts.
As already stated, the wider is better comment works to a point. Yes wider tires on our truck will put a bigger contact patch down and help with traction, but it also depends on the type of tires. I've run pretty much every size tires from 275/55/17 to 255/50/17 on my R/T. So far, the best all around tires I've used were the 255/50/17 BFG G-Force KDWS, and the tires I have now which are the Kumho ECSTA STX. The two choices in the 275/50/17 size are both POS IMO. The 275/55 size works pretty good and you have some decent options, but you will lose some handling due to the taller sidewall. I had the Pirelli Scorpions in the 275/55/17 size and they had awsome off the line traction, but rolled over in the corners too much for my liking. The 255/50 size is the best size for the R/T IMO because you have tons more choices due to it being the stock size for the '94-'96 Impalla SS. There are lots of tires I haven't tried that get good reviews. I'm thinking of getting the Fuzion ZRi's next.
Also, another thing to consider, if you are going to drive in the snow, wider is definitly NOT better. With a wider tire, you will sit on the surface and spin longer than with a narrower tire which will cut down to hard road surface faster. And once again, the BFG G-Force KDWS worked great for me in the snow. For an ultra-high performance all season tire, you wouldn't expect it, but BFG has done thier homework and hit a home run on this one. Of course it won't be as good as a dedicated snow tire, but I had no problems driving through 4-6 inches of snow on top of ice with the BFG's and was still able to pass vehicles and dind't feel unsafe at all. The only time I spun the tires was when I punched the gas to test out the road surface, and I only had to do that because the tires were working so good, I couldn't tell how bad the road actually was.

That spoiler idea only works at high speeds, won't work on the line.At 80mph it would work good.

50 and 55 series profiles for draggin? This doesn't make sense to me. If you put a wide tire on with a short sidewall, your contact patch is short (front to back) and wide. That's GREAT for racing through the corners but crappy for a launch. You need more sidewall, IMHO. If you have a tire with a taller sidewall, the footprint will be longer front to back and give the launch traction (of course it does sacrifice cornering traction because of the narrower footprint).
Oh, and I got a good laugh on the pressure per square inch reprimand that Trent gave.

Wal,
What do you mean by "longer footpring" with a taller sidewall? A taller sidewall won't necessarly mean better traction for drag raing, it's not like a wrinkle wall slick where you need to sidewall hight to help hook-up. I run 50 series drag radials on my car, they work great.

What I mean is that if you looked at the footprint of two tires, let's pick some make-believe numbers...
225/75/15
225/55/15
The footprint on the 225/75/15 would look like this:
.....
.....
.....
.....
.....
While the 225/55/15 would look like this:
........
........
........
The taller profile yields a footprint that is long and thin compared to the shorter and wider footprint of a tire with less sidewall.
It helps to think of the footprint and the ballooning of the tire when trying to make sense of what I am saying... at least it helps me to.
Anyway, the longer and thinner footprint will give the most grip for take-off and stopping, but you sacrifice cornering. The wider footprint will sacrifice take-off and stopping friction, but give better cornering friction by the wide footprint offered.
Maybe your 50 series is so sticky that it gives you all the friction that you need on take-off and provides better cornering then a taller tire, to make for a nice all-around package. You will sacrifice treadwear for this, but that might be an ok trade-off to you. For argument's sake, a 70 series tire could do the same job with a harder compound or a better job with your current compound, but would not give as good grip in the curves.

Wal,
I think that has more to do with circumference then sidewall height.
Of those two given tire sizes
the 225/55/15 is 77.72" and overall diameter of 24.74"
and the 225/75/15 is 88.84 and overall diameter is 28.28"
Thats 2.5" taller and 11 inches more tread around the rim.
Would you have the same effect if you were to say go with these tire sizes?
225/50/17 81.2" and 25.8"
225/70/13 79.8" and 25.4"
Thats as close as I could get to the same dimensions
