Anyone running DR on 17s? What tire pressure do you use at the track and what do you launch at. I couldnt get my tires to dead hook...any tips? Do you do a big burn out?

i ran my 315/35/17 nitto dr's at 16 psi or so at the track. good burnout (2nd gear!)

I run 25 psi, the sidewall is hard, there is no need to go below 20... Also, they are still radials, so I do about a 3-5 second burn out, right when they start to smoke I roll out of it. Don't do any dry hops, the first launch will be your best one... ;)

Same here, except I usually run 18psi on mine. Big nasty 2nd gear burnout's are the key.
Stanginalive drops his down to 14psi.

20 psi and only a few seconds of burnouts for my M/T's and they are fine.

Thanks for the info guys. I did one run with the tires down to around 20psi and a 4000 grand launch and was not impressed with the 60ft at all. I was getting ready to run again and they had track issues so I never got to run. Next time I am going to do a big burnout.

yeah I got subframes and lower control arms...I will be happy with 1.8s...I could get a 2.2 all day easily on my nitto's. what should i launch at

I ran nitto 275's on my stock wheels (17x8)and am currently running 315 BFG's on 17x10.5 wheels. As others have said, my best performance has been at about 17-18 psi with a 3 second, 2nd gear burn out. I usually start by launching at 3000 rpm's and adjust from there, increasing by about 500 rpms each pass until I lose traction. A lot of it depends on track prep. For comparison my car has about 245 rwhp. Last year, with stock suspension / wheels I averaged about 1.91-1.93 on the 60. So far this year, with the 10.5 wheels and lowering springs (Sportlines) I am averaging a bit higher at about 1.98-2.00.
Friday at Ennis the track was hooking great. I got up to a 5k launch with minimal to no spinning and got a best 60 of 1.89.

315's are too big of tires for such a narrow wheel (10.5). Because the tire is too big, not only does it 'poof' over the lip, but it also crowns in the middle. This is a bad deal on more than one level. If you need me to explain why, all I ask is your friendship in return. Haha - I like me.
Secondly, by adding the larger wheels and tires, you have effectively slowed down your car. When making 245 RWHP, it's probably not the best idea to add unsprung rotational weight. Actually, it's a bad idea all the way around.
Remember when I advised you to go to a coilover setup instead of just springs? Well, Chilingsworth - there was a reason for that too. It would have helped you greatly at the strip, while allowing you the flexibility to adjust them back to street specs. If you haven't clued in by now, you're kind of fighting an up-hill battle with your current set-up.
Your larger wheels and tires and, stiff suspension are not going to be your friends at the dragstrip. Just thought I'd lend you some advice. I kind of feel bad for thrashing you the other day. Well, maybe not (hehe).
By the way, if you've never tried the double-banana-split-extra-everything from Braums, give 'em a try sometime! But please, bring a designated driver - they're that good!

You're not telling me anything I didn't already know. I did not lower my car nor put on wider wheels to improve times.. It was purely for asthetics.

Then what are you doing at the dragstrip? Let me get this straight - you intentionally put too big of tire, on too little of wheel? Because you think this somehow looks good? As if that wasn't enough, you then go and put on a stiff suspension and then think it a good idea to go drag racing?
I'm not really following the logic. Want to go to Braums for some icecream instead? I know I do!

Listen, I know you like being the proverbial Dingleberry attached to all my posts, but, it's getting a bit annoying. If you feel the need to post so much, get in a chat room. I'm sure many a 400 pound ham-sandwich-wrestlers would love to meet you at the local all-you-can-eat. But beyond that, your pathetic attempts at making a point add up to nothing more than a freshman pulling at a panty gurdle.
As to your asinine response, an over sized tire on an under sized wheel is not defined as 'looking good'. That's just like the plus-sized gals trying to fit all 300 hundred pounds of themselves into the latest thong. Hey, they might get it on, but nobody's gonna accuse them of looking great. Nor is a stiff suspension and more unsprung rotational mass the best b-line to going fast. But then, you always seem to know what you're talking about. Genius.
Maybe when you get done ballwashing Chili, you can continue painting the rest of your sled that great looking orange color you're so proud of.
Thanks for your time.

I don't follow you around douche:rolleyes: 300 hundred pounds(isn't that kind of redundant)? Are you alluding to yourself not being able to fit into the latest lingerie? I know more than you think about unsprung weight. My sled is all one color, yet you won't even post up your sled, because then EVERYONE would realize who you are.

And lowering a car makes it launch worse... Tell that to all the guys with race cars on the ground... There is more to suspension than just movement. Hell my dad's car is on the ground, and it leaves pretty damn well. So lowering a car the proper way, with larger tires out back, doesn't make it hook less... :( It made my Cobra stop bouncing. :o

Yea, Nitto recommends a 10.5 on their 315. BFG recommends an 11 for their 315 but I wouldn't sweat the 0.5 inch. If we were talking about forcing a 4 inch wide tire on a 3.5 inch rim, then that would be a different story.

1. Lowering a street car with eibachs will hurt you at the strip. Keep in mind nobody here is factoring in your Dad's racecar.
2. You guys got me on the 315's. Due to old age and a slight loss of memory, I was under the impression that 315's required an 11.5 instead of a 10.5. The preferred measured wheel width is 11.
In retrospect, I run a 275 on a 10 inch wheel (not a Mustang). Looks good, and, feels great for the street.

My best 60' with stock springs and 8" wheels... 1.89
My best 60' with Sportlines and 10.5" wheels...1.89
My fastest 1/8 with stock springs and 8" wheels... 8.64
My fastest 1/8 with Sportlines and 10.5" wheels... 8.71
My car is not a purpose built race car. It is a daily driver that I enjoy taking to the drag strip to minimize the urge to get on it on the streets. A small time loss at the strip is worth it to me.
I am happy with the way the tire fits the wheel..

Chilingsworth -
Hey, as long as you're happy, that's what matters. But, unless you do back-to-back runs on the same day, with the different wheel/tire packages, those results have way too many variables in play to be accurate. I'd like to compare and contrast my wheel/tire package with yours but, then I'd have to let you into my real world. And, I'm just not ready for that. I guess I'm just shy! Not because you think I'm someone I'm not, Detective.

What size do you think is supposed to fit on a 10.5 inch wheel? maybe you just need to learn about the different tires and different sizes each tire is before you post.

Back to back runs on the same day aren't even telling, tito. Launch rpm's, shift rpm's, engine temp, wind gusts, and a dozen other variables affect times. It is not as if it is a completely controlled environment. My times can vary as much as 2/10's in a 2 hour period.
But of course, you also know all of this, and merely fabricate your silly posts simply to stir up controversy.
Much like the amateur golfer, I enjoy the feeling of beating my previous best, and that is what I strive to do at the track. The fact that I have at least matched my best 60' and am very close to my best 1/8th, with changes that typically carry a negative impact, is good enough for me.
Regarding you "letting me in to your real world", you seem to imply that this is something I desire. I could really care less tito. The offer has been made on several occasions for you to come out, whether it be to the cruise or G2G, just like it has to anyone else expressing interest. Track threads are posted all of the time. You choose not to come, and then you choose to make personal attacks. I am glad your little games give you satisfaction, but I tire of them. Do what you like tito, I am done with you.

What personal attacks? You're going overboard. You owe me an apology, Sire. Also, I did go to the last SpeedTek Dyno Day. I went and saw nobody from this forum. I even inquired as to who would go from this forum to the Dyno Day. I made every effort. But still I'm ostracized. I am hurt. Where's my bag of Funions.. .. ...
Tiring? Tiring?! You know what's tiring? Being glossed as someone else since day one. That's what's getting old. That, and, I'm thinking of giving my hair that salt-n-pepper treatment so that I look a bit more distinguished. What say you to that, Chilingsworth?

I hit reply then had a customer and then finished the response so you hadnt posted yet, but I had read all the previous posts.
All tires are different in sizes so some 315's do fit. You just sounded like you were attacking him for putting the wrong size on his car. He wants it to look good but he still try's to get the times the best he can for what he has. That was his question and you were attacking him for what he likes. So you were the one who needs to read the question and answer the question not be a dick.

My dad doesn't have a race car, its a 3800 lb convertible Fox that is slammed on 17"s... it isn't fast, but I was commenting on the fact that it is VERY low and hooks better than 90% of the street cars on this site, including both of mine, one of which is higher off the ground with drag race specific springs...
Again, there is more to a car launching than it being low or not.

Please re-read if you need to. I never said lowering a car was bad for drag racing, I said a stiffly sprung suspension would not be the best route to take if drag racing is your forte. Appreciate your efforts.

IMO, it depends on the DR
Until recently I ran either BFG's or Nitto's. 275/60's or 275/50's. I would run them at 15psi and had to do a monster 3rd gear burnout. My best on the NItto's was a 1.73, and on BFG's was a 1.65.
Now I am running the M/T drags. I am using about the same pressure, but a mild 2nd gear burnout seems to do very well, and puts the 60's in the 1.6's with an AOD.
430-450 hp in these cars, all Fox stangs.
