As far as I know there arent any drag slicks made in an 18" wheel size. For that matter, nothing over a 16" wheel in drag (tube type) slicks. Cheaters/Drag radials come in 17" sizes but are limited, so you first need to figure out a 16 or 17" wheel that will fit your car and them pick your poison on tire size.

Another thing is we dont have lockers or even limited slip rear diffs so traction could be a problem even with slicks. I have 285's under the rear of my car and it WONT burn out in a straight line anymore. I can still get the stink tire thing (single track) going around a corner buts that's for high school kids.

what the hell do you need a slick for. you will end up going slower ;)

which box did you click to get a 6.1 in your rt?

Be nice roy,

Your dealer has SRT's on sale for invoice again, Mags and a Charger.

hm, do i need another one.

i dont understand the concept of putting a slick on a car that wont go into the 11s. letalone 60' 1.6 or lower.

The OEM Conti's will become slicks in no time at all. Be patient for a few thousand miles. :wink:

I just ordered some 245x40x18 drag radials today. There are several companies that offer this size. My last trip to the track I could not get my 285x50x18's to hook up at all. They are also a little bigger diameter than the stock size. It could have been the track, temperatures, tires or ME but my 60 foot times were not good.
We'll see if the smaller diameter and stickier compound helps at the track this weekend. I don't think it can hurt.

65 - A few words of help.

First with a slick ( biasply ) you shoudlnt run a radial front tire. Given that I doubt your going to get skinnies for teh front stick to a drag radial.

Cheater slicks will work fine, you need to find a size you want and get them mounted. If you have teh right offset you can go out to 295ish in width, but i would suggest running a shorter tire over all if you can ( gives you a little more gear )

Hemi31 just got some wheel to mount his drag radials ( i think he even posted some picks ).

I am hoping I can get by with my 295's at Etown, but I am loosing some gear on them ( they are about an inch taller than stock ) maybe I can mooch a set for a run or two.

There really isnt a need to go with a true tube in tire type of slick on these cars, a good radial slick should work just fine.

Kim, have you run that tire yet? What are you doing for a front tire? that's nearly a 10% size differential from the stock fronts. I would hazard to guess you are going to be throwing ABS codes, and probably put the tranny control module into limp mode if you run those sizes together.

Has anyone tried something like the BFG Drag Radials?
Also, I dont think that there would be a critical problem with codes and I dont think that it would go into limp mode. Just jigger out Fuse 11 when your are done racing.

ImaThorp- I just ordered them (BFG Drag Radials 245x40x18) last night so don't actually have them on the car yet. I guess we'll find out about if the difference effects anything when I pick them up. I'm going to set the flashpac to this tire size and see what happens. If everythings OK I'm off to the track this weekend

Hmmm, this flashpaq sounds interesting. I wouldn’t have guessed it could accommodate for a 3" (79 revs/mile) swing in tire diameter and still shift the tranny properly. Also I'd be real curious to see how the 245 performs against the that same tire in the 265 size (-19 rev/mile) hardly a difference I know, but that could save an extra shift point or keep the rpms in the peak torque longer etc.

Keep us informed on how it all works out. More specifically trap speed, what gear you cross the line in and at what RPMS.

This is my setup:

Borbet Type TS rims 18" x 8.5": http://www.tirerack.com/upgrade_garage/WheelSearch.jsp?&autoMake=Chrysler&autoModel=300C+Rear+Wheel+Drive&autoYear=2005&autoModClar=
BFG drag radials 265/40/18 26.2" dia. http://www.tirerack.com/tires/Spec.jsp?make=BFGoodrich&model=g-Force+T%2FA+Drag+Radial

Tire diameter is down to approx 25.9". I trap near (stock) red line in 3rd gear.
Have to really roast them to get to hook properly. May be of limited use without GSM mod/pulling fuse 17.

Worth .15 +/-.

I got the MT ET Streets and put them on a 17'' cobra bullit wheel. These are basically slicks/ very little tread...but dot approved so you can drive to the track. I can't imagine needing any more traction than these provide after a good burnout. On the normal street it is hard to get them to even spin. This setup was worth 2 tenths for me. It is very easy to cut consistent 2.0 and 1.95 60 foot times with these tires. I thought the smaller diameter in the rear would be more noticable as far as improving the gear ratio. I do not have any drivability issues w/ the bigger tires on the front and smaller in the back...i just keep the GSM trac mod engaged when running these and I'm good. It is fun to burn out as much as you want at the track knowing you aren't melting all your street tires away. I say worth the $$ and hassel to put them on before heading to the track. Here are some pics:

go here and click on ET Street on the left side to see the tread.

Meister- how much air pressure were you running with? Did you try different amounts?

thanks Meister for the FYI. I wonder if the wee smalller tire Kim has coming will get him into fourth gear? Please, come back and let us know Kim!

look roy, i didn't ask for insults. i have a traction problem and i asked about slicks for the track. i don't need to hear about 6.1L, 11s or 60' times. if you're trying to teach me your wisdom, that's a poor way of doing it.

whoa, im not trying to insult you man. im just saying that there are other methods than a full out slick. you have to realize that a full out slick might be nice for traction but there are some negatives you forget about

1)they only come in certain sizes and i dont think anyone makes a real slick over 15" (or even 16"). havent looked much, but i dont think they do.
2)too big a slick WILL slow you down. you will have added rolling resistance from the bigger/stickier tire
2B)the tire will GROW in diameter. slicks are soft and dont have the steel to keep them conformed like a radial. that means your overall gear ratio might go from a 2.90 (whatever rt is) down to a 2.70 from the extra tire grow.

if you go with a smaller tire like a drag radial you should have all the sticky you need. you can gear up by sizing down your tire then too.

you say you cant hook, why? maybe your street tires arent good for track. maybe youre doing too long a burnout (street tires only need a small burnout), maybe youre going through the waterbox instead of around it, maybe youre doing a burnout in the waterbox, maybe you have too much air in your rear tires, etc etc. these are all reasons why you might not get traction at the track/street/whatever.

instead of looking for a full out slick you should be looking for reasons why your car, no offense to your power output, isnt hooking with a 5.7. i will bet you cash money that you will will lose atleast 1 or 2 mph if you go from a street tire to a slick. ive seen it happen when v6 camaros think they need a slick and up going slower. basic principals tell you that you will increase rolling resistance and end up with a lower (numerically) gear=slower et/less mph if you cant use the tire to its full potential.

i always ran the smallest slick possible on my car to get the best ET. i understand that you want to go faster and reduce spinning, but id chose a little spinnage off the line on a street tire than a dead hook on a full slick with my magnum. you will go faster with that route.

and i thought you had a 6.1 in your rt cause ur pictures showed 6.1 valve covers. my mistake i guess.

I went to a different track this weekend and made 8 runs. My average time for the 8 runs was 13.88. 13.77 best. That is .49 less than a few weeks ago. There could be three reasons for this improvement.
The first is the track. The this weekend was very nice had a nice base laid down.
The second is the weather. The weather was a little warmer +10 degrees that may helped the traction but hurt the HP.
The third was the new BFG drag radials! I had excessive wheel spin a few weeks ago with my street tires. These BFG's really stick. I had virtually no wheel spin. I also got a get reduction from the tire size. They are also lighter than my stock tires. Downside is they look goofy but I did'nt buy them for looks.
Here is a comparison.

Meister- how much air pressure were you running with? Did you try different amounts?I've tried anywhere from 28 psi to 14 psi. The highest psi that you can hook reliably will give you your best times & speed. I'll probably start at 26 psi next time I'm at the track.

The key to a proper launch with the BFG drag radial is to heat the tire fully - which requires a massive burnout. Spin them till the smoke is pouring off the tires, which is about a 4-second burnout. It'll take a GSM ESP mod or pulling fuse 17 to fully heat the BFG drag radials with a 5.7L, IMO. And use the water box.

thanks Meister for the FYI. I wonder if the wee smalller tire Kim has coming will get him into fourth gear? ...It won't, especially if he's raised his shift limiter.

Optimimum is to trap wound tight in third gear - just short of the shift limiter.

sorry I had technical problems. here is the rest of what I wanted to post.

285x50x18 aprox 60 lbs measure 28 7/8" summer rear tires
245x55x18 aprox 55 lbs measure 25.3" frt tires & winter rear
245x40x18 aprox 45 lbs measure 25.75" only to & from strip
245's are on stock wheels. 285's are on modified stock

hope pictures are not to small. had to reduce to attach

I started at about 26 lbs and went down to 20. Traction was great at all presures tried & times were very consistent. I think the 20 to 22 was too low because I had a lot more wear showing on the outside and almost none on the inside.
