Chris, the NT05 275/40/20 on all corners are hands down the best tire in 20in for track days. (Not drag racing) I run the 275/40/20 front and 315/35/20 rear and I love them, (I'm on my second set) the only problem is Nitto has stopped shipping them and no one has any in stock. If you can find a set buy them or PM me I want an extra set:thumbsup:

275-40 sidewalls are a little smaller then I wanted. I figured 255-45 because I like the 29" sidewall

actually I'd love to run 315's on a 20x10 rim but everyone says it looks rediculous and waste of money and added weight?
Also not sure how the car is gonna handle with that tire on a rim a tad bit small for its size on a road course.

Chris, just for reference:
255/45R20 = 29.04" tall
275/40R20 = 28.66" tall

Ride height difference will only be .19". My first set of drag radials were 275/40R20s (with the 255/45s up front) and there was no visual drop in height in the back.

All things equal, smaller sidewalls generally equals better cornering and wider tread generally equals more grip. You are correct, the 275s are slightly heavier. However, both tires will fit your stock 20x9s just fine.

I am also considering the NT05s. Another thing to consider: TireBuyer.com prices for NT05: 275/40R20 = $217.26 each, 255/45R20 = $187.66 each. Approximately $100 less for 4. (Both in stock.)

This is a different route to go, but there is one more tire size to consider: 255/35R20 26.97" tall. That's a bit more than a 1" drop in ride height from the 255/45R20s. Your car is already lowered, so you may not want this one. But the price is only $138.85 each. For four, that's $313 less than the 275/40R20s and $195 less than the 255/45R20s. My car is not lowered, so the 1" drop should work out fine, but I'll get separate race wheels.

[See you soon! :)]

Hey Mike, Thanks for the tip. Im still wrestling with the idea of buying new wheels. No wheels availible really have my attention except the superbee srt alcoa wheels (same as the new 392 wheels) or maybe some torq thrust II's but the Torq thrusts would have to be custom ordered and cost almost $2000 just for rims.

Well if you're worried about weight on your tires, wheels is where you can really save weight. Usually, cheap wheels are heavy. My wheels I bought for my drag radials are something like 5-10 lbs. heavier than my stock wheels and tires. The SRT stock wheels are really nice, but really expensive (as you know). I think the Torque Thrusts will also be heavy.

I've been looking into TSW wheels, but I have to do more research. I like the "Nurburgring" style they have. They list their wheels for Challengers with a bolt pattern of 5x114.3 instead of 5x115. The 115mm bolt circle is correct, the 114.3mm is the metric equivalent of 4.5 inches, which is incorrect. I don't think "close enough" is good enough, but I could be wrong. They also only have 20x8.5s listed in their stock. In any case, TSW wheels are meant for racing and are lightweight. Certainly better than cheaper heavy wheels if weight is the main concern. Although, if looks are no object, the wheels I got for my drag radials were less than $150 per wheel. I don't care for the looks of them, but for drag racing, I don't really care since they don't match the fronts anyway. They are also the heavy wheels I mentioned earlier. For road courses, I would like to have nicer-looking, lighter wheels, but I can't afford $2000/set either.

What can I say, It's an enigma.

[If anyone knows, I'd be interested in the answer to the 114.3mm vs. 115mm bolt circle question.]

Actually,I realize now since im not going to really be racing or competing at a track day (not for a while atleast) Im more concerned about having a good quality setup that looks good and performs good enough for me to have a good experience on the track. Saving 5-10 pounds here and there wont make much of a difference to me. Preferably I'd like some nice looking wheels and big tires without being too big to compromise safety.
