I am looking to get some drag radials. I currently run Volk GT-S 19x10.5" with 285 street tires. I was looking at getting GT-S 18x11" with a 305 drag radials. My question is I would have the traction I am looking for but would the wieght of a 305 with an 11" wheel compared to a 275-285 with a 10.5" wheel slow me down on the top end? Please only reply if you have some experience in the matter I would rather have facts instead of opinions. Thanks for advice in advance.

you can easily fit a 305 on a 10.5 inch wheel...i have it on a 10 inch ...u can actually fit a 315 on a 10.5inch...so u know...

If your looking to better your 1/4 times then do what most of us have done and go with a 15" x 8" wheel with some M/T 275x50 drag radials. Its a proven setup with much less weight.

yea theres no point in spending the $$$ for volk wheels you use only for the track. Unlessyouhave money to throw away like that. If you do please send some over my way

Some people trap lower with sticky tires, others higher with sticky tires and better 60ft's. I am an example of the ladder.

i've gone to the limits, i fit 315 on a 9.5" rim and i just fit 275 on the stock 18x8 350z rims.

I am getting the match volks on the back thats not the question. I just want to know if the top end sacrafice would be worth the bottom end traction? Or would the big wide tires just take too much off the top end?

Read my post again-you may pick up 2mph by going to DR's from street tires, or you may lose 2mph from the added traction. EVERY car/set-up is different. AGAIN--->I pick up 1-2mph with slicks over street tires. 105mph on street tires NA, 107mph right after on slicks with a .3 better 60ft.

One thing is for sure-with DR's used correctly you will greatly improve your 1/4 time. Worrying about top end vs low end traction is silly. What good is your top end (second 1/8 mile) when your already losing by 5 cars to the first 1/8 and wont make it up the second half?

the 315 radials give me less spining ????

Alberto thank you for your time it is helpful to get info from a guy that runs times like yours. It is not the switch from street to DRs it weather the 305DRs will hurt or help the quarter mile times compared to 275-285DRs. I have no doubt my times will improve greatly with drag radials my 60' are 2.09 with any attempt at a a lunch resulting in massive wheel spin.

Why would you think its going to hurt your 1/4 times? It really doesn't matter what size tire you use at your power levels. I've used 275's, 295's and the size didn't make a damn bit of difference. I'm running 11.5's in the 1/4 with 1.7 60' times on 275's

The biggest killer in weight of a tire is making it unnecessarily wider, his question makes sense, assuming he is getting his power down, he'd want to have as small a tire width as is possible.

I think its hard to just compare tire size, you have to compare overall tire weight, tread width, the compound of the tire, etc. Some radials are very light, some aren't...

Thank you Peak your right its the weight I am concerned about. obviously with 305 drag radials traction will no longer be an issue but I am afraid the wieght will be slowing me down and there for the gains seen in the lower 60' times will be lost at the top end due to the wieght of the wider(heavier) tire. I am asking because I am not sure if this is the case or not. The wider tire may not slow me down on the top end at all?? Most people seem to think the wieght wont slow me down is that correct?

Oh, I misunderstood. If you currently have 275 DR's stick with them, that is plenty to get you hooked up judging by your times/trap in your sig. If you feel you need slightly more traction, 2-3 more lbs of wider DR weight likely wont be seen. I have a diff experience but it may be relevant. I run the EXACT same times with 255/35 19's up front as I do with 245/40 18's on stock track wheels up front. The 19" wheels weigh about 2 lbs more and the tires considerably more with no ill effects, tested it out the same day, nothing changed in trap. Good luck!

and for the rear ???

2 0r 3 lbs of tire weight is not going to make any difference.If your concerned about weight do what I said about the wheels.

READ CAREFULLY....15x8 wheel... 275x50(26") tire.
This is not rocket science. A couple lbs of extra weight is not going to make any difference on the top end, the launch, or the drive home.

Your tire size is not the problem. If you really want a fast drag car, get an extra set of wheels for the rear (RX7, 300ZXTT, etc.) and use those at the track with a Mickey Thompson ET Drag Radial. There is no reason to change your entire wheel set-up to make a pass at the drag strip here and there. You need a tire that has some sidewall compliance, and I don't know of any in a 19" size. There are some in 18" (BFG, MT ET Street Radial), but that's going back to changing your rear tires ($$). I'd opt, as I have myself, for having a dedicated set of drag wheels.

Also, you want to focus on your suspension settings. If you have 3* negative camber in the rear for the street, you are minimizing your contact patch for drag racing.

Didn't mean to say whether I agreed or not, just try to make sure his question was understood because I didn't think it was clear but have seen so many tire debates that I expected it.

I also agree that 2 lbs likely won't make a difference - and the weight is something felt MUCH more in tuning suspension for a road course than building a drag car.

+1 for this kind of answer ... but , dude can u explain more pls what kind of suspension is the best for darg racing car ???
