Im trying to find some d.o.t approved slicks for my car because i run a street legal series and i cant run full slicks.

the smallest width ive found on these from hoosier, MT and M&H is 10.5 which is roughly 255mm. I was able to fit 255's on my 17x7's so..im sure i can fit them on the stock steelies.

my problem is, will it clear? 26x10.5x15's on stock suspension? my 17x7's do with 255x40x17's ..i cant find the height specs on the slicks though.. so not sure if a super high profile slick would fit, unless it was like 255x50x15, would be about the same diameter as my 255x40x17's

are you running springs/shocks?
if so go look at your car between the mount and your tire and see how much room you have. figure out the diamater of the tire on your car and compare to the 26" diameter you want run.
i dont think it will fit, but it may if you're gonna bulge a 255 on a 6" wheel.
good luck.

26x10.5s will fit under an S13. you need an 8" wheel.

slicks arent dot legal iirc. drag radials are tho.

they make d.o.t legal ( street legal ) slicks

ET Streets arent slicks. they are a DOT Bias Ply tire. essentially just grooved slicks.

ET Streets wont be legal in a drag RADIAL class though.

Well..the class isnt a drag radial class..its a street legal series. so as long as its legal on the street ( et streets, and radials ) its legal for the series.

anyway.. all I have to work with is the steelies. so im trying to figure out what is the max width i can fit on them. I thought they were 7''? are they 6''? if so, that might be a problem.

they are 6". i run 225s on the stock 15x6 alloy and it bulges out more than I would like but I still run them.

225mm = 8.858241"

steelies are 6 or 6.5s. If you're stuck with those, look for an 8" slick. That would still probably be more than enough for your car. 10.5s are overkill really.

i agree... this would be the tire size i would run if I was going tot get some new tires. However, they are not street legal.

24.5/8.0-15 MT ET Drags.

Jay, do you have any pics of your car with your current 8.8 slicks? I really want to run something with close to a 26.0 diameter because my front wheels are 25.03, I think if my front end is higher than my back, not only will it look like ass, it will probably mess up my launches.

Im giving up on the idea of find ET streets..so, my best option for MT drag slicks are: 26.0/8.5-15 thats a 215, im sure it wont stick out with the steelies.. but, with the 8.5's FIT on the steelies? ( did put 225's on my 15'' alloys )

If so, i think thats what I'll go with...

you're at the track......on steel wheels......with slicks on them..........and you're worried about how the difference in tire height will look?? I'd run pink steel wheels if i knew i was going 1.45 60fts on em http://forums.freshalloy.com/images/graemlins/grin.gif

And if anything, more weight shifted off the front will HELP your launches, not hurt them.

who cares how it looks? just worry about getting the time you desire.

actually this post made me think for a second. caring about how it looks went out the door whenever you decided to use steel wheels LOL.

im not worried so much about the looks as i am it effecting the launch. I think i could get away with the 24.5x18x16 though. I'll buy those. thanks jay!

Why are you "stuck" with the steeles? Can't you buy some junk yard wheels that are 8" wide ugly as hell and cheap as hell. Then get the 26x10.5 tires. 24.5x8 is not enough tire for the power level your bio states.

yes, it is. Ive seen cars making 150+ more lb/ft cutting sub 1.50 60fts on 8" slicks.

Agreed. A buddy of mine had a 450ish WHP cobra launching on n2o cut 1.5 sec short times on 8" slicks. Hook and go baby!

I am not saying you can not cut good 60ft's with 8" slicks. What I am saying is that with a 240 with minimal suspension mods and ~400HP there is a good chance you will loose traction with a 8" slick not to mention the MPH sacrificed with the smaller tire hieght. My buddy with near stock rear suspension cuts 1.4 60ft's on his S13 with 26x10.5x15 MT ET Streets. My car (full weight S14 with stock s14 turbo) cut 1.6 60ft's with completely stock rear suspension on the same tires.

Plus IMHO 8" 24x8 slicks belong on the front of Hondas and look dinky on a 240.

i'd really like to run 26x10x15's ..we'll see if i can get my hands on some other wheels before i order. i mean, my street tires are 255's, i cant justify running slicks smaller than those. lol

btw..your friend with the s13, what wheels is he running?

You're completely off base comparing slicks/street tires, trying to justify a purchase by comparing widths. Not to mention........dont you have your 255's squeezed onto a 7" wheel anyway??

ehhhh... you're sorta wrong here. A smaller tire will give you better acceleration. It basically shortens your effective gearing. You should be deciding how tall a tire you need based on your gearing, hp, and weight. Ideally, you want the widest tire you can fit with the shortest height that will not adversely affect your top end ie, you should be running through the traps at your hp peak in your highest non overdriven gear.

Feel free to use http://www.f-body.org/gears/ to help you pick which will get you to your goals.

I understand that the effective gear ratio is changed based on tire size. For my car with less horse power and more weight than the car in question I am in 4th gear in the power band at the end of the quarter mile with 26" slicks. I was taking those experiences into account when I was refering to loosing MPH with the shorter tires. If he can get the car to hook with the 24" slicks he may be cutting his gearing close. Assuming 7000 RPM as maximum engine speed and stock gears using a 24" slick yields a top speed in 4th gear of ~120 MPH using a 26" slick yields ~130 MPH. With ~400 HP and good 60ft's 120 MPH traps are not out of the question. I would rather build with a certian level of growth room. Not to mention he still will be more likely to cut the good 60ft's with the wider slicks which we all know is the key to good ET's.

with my street tires, that are closer to 24 to 26, im trapping at 118 at about 7000rpm in 4th. if i could get alittle more gerar out of 26's id be happy

with 22" slicks (and 4.08 gears) i was crossing the finish line in 4th at around 7k and my trap speeds were the same as if i had my 24" drag radials. My ET and MPH wouldve been better to but my top speed limiter was kicking in prior to the end of the 1/4. I don't see how you, with 26" tires, were in the power band when crossing the finish line. what rpm were you crossing at?

SRENITY
03-11-2005, 10:10 PM
I have stock turbo so my power band is pretty broad. I did not say I was at red line just in the power band. I am between 5700-6000 at the traps. Trap speeds are about 110.
