** drag zilvians chime in**

[Tom N]

Just for the record I had strongly considered trying the MH muscke car drags for street/strip use. As they are a wrinkle wall bias ply and not a radial but they don't have the size I'm looking for.
I don't think the 235 will be wide enough and think a 26in tall tire is taller than needed.

[Tom N]

Guys there's no such thing as a bias ply radial.
It's either bias ply or radial. Not both.

[down_south240]

You might want to call Mickey Thompson and let them know that.

[Tom N]

That's a bias ply tire. Not a radial.
What the hell are you talking about?

[Tom N]

Let me guess you think radial means DOT Street approved correct?

[db_s13]

tom n- you really should read to what is being typed to you and read the specs for what ever tire you want...and just for the record a 24.5x8 has a smaller tread width then a 235 tire...stop debating bias vs radial it doesnt really matter if your looking for a bias ply tire

The 24.5x8.5 has a tread width of 8.5
The 235 has a tread width of 7.5
What were you saying againg?

look at the specs of the tire with and what i typed (24.5x8 as you last said in the above post but have since edited it)

24.5x8.5=8.5" tread width
235=8.4"
so that .1 is basically a wash and with a 24.5" tire your not going to get the side wall flex you are after unless you have very low tire pressure as previously stated

but i do agree with the bias vs radial thing

I said 24.5x8.5 m&h many times including the first post in reference to this. I said 24.5x8 once right after saying 24.5x8.5 in the same post and fixed it seeing as saying that one time out weight the several other times saying specifically 24.5x8.5 m&h.


The 235 muscle car drags that we're posted are a 7.5 in tread.

I'm not really looking for a dot tire though. I have drag radials for street use. Looking for a full slick.

Most people around here use those terms interchangeably when talking about drag racing. Most races even specify no bias ply radial for rwd.

In 20years of racing I've never seen a sanctioned race say no bias ply radials.
That would make no damn sense.
You have bias ply DOT & non DOT
And you have radial DOT and non DOT. Such as a non dot radial slick.

First time for everything I guess. I have seen them say DOT approved radials, non bias ply only. Either way a 24.5x8.5 seems like a rather small size for a rwd car.

[Tom N]

I'm looking to argue what a radial is. It's a stupid discussion for 3 year olds.
I've calculated gearing for a 26 and a 24.5 and the 24.5 seems like a better fit but was looking for some real world use in a 400hp S14. Is there such a person here?

[Tom N]

A dot approved radial non bias ply only makes perfect sense.
A radial is a non bias ply and most all radials are dot aside from a very specific radial slick like made by MT which isn't DOT.

For example a nitto 555r would be a non bias ply DOT radial.


Yes a 24.5 does seam small for a rwd as most out there aren't smaller imports. That's the point if the original question. In this case is the 26 warranted on a car like this one.
There was a S13 at the track Saturday with a stock red top swap cutting 1.6 60fts on a 22in slick. He got them for free. Got me thinking how a 24.5 would work. I'm looking for just enough tire. Not more than I need as that's added weight and rolling resistance.

[down_south240]

Right, but if you say DOT radial, there should be no need to specify non bias ply since they make no bias ply radials. Either way, I'm done thread jacking. Here's a video of me going 11.91 in my brother's LS1 240 on I think a 255/60/16 to get back on topic. http://youtu.be/sBZXDgP9dxY

I agree there no reason to say non bias ply if it mandates a radial. I guess it's for those who think radial mean dot?

What was the 60ft? And what rpm did he cross the line at?

[down_south240]

I was driving for that run, and I think the 60 ft was a 1.7. It crossed the line at the very top of 4th, around 7000 rpms, but the longer gearing in the Q45 rear has fixed that. Now just to get back to the track and try it out.

What transmission and rear gear?
Top of 4th if its a 1:1 gear with that tall a tire would put you at a pretty high trap speed.
I want to trap using most of 4th. Right now I trap in the low/mid 120's with a 275/45/16 which is about 25.5in tall. But I'm not using most of 4th when I cross.

T56 trans and I think it was a welded s13 rear end back then, either that or a NISMO 2 way with stock gearing. We actually had a lot of trouble with hitting the rev limiter in 4th and were trapping 117-118. We were trapping higher with a smaller radial, but the times weren't nearly as good.

Edit: What kind of times are you running with a trap speed that high?

A t56 in 4th is a 1:1 gear. with that tall a tire with stock rear gear puts you WAY over 118 at 7k rpms.

Car traps high 11's with radials and crappy 60fts.

All I know is what the time slips say. We consistently trapped around 117 with the crappy s13 rear gear at the top of 4th. Just double checked, and the tire was a 255/50/16, so it was a little shorter.

And are you wanting to improve your times, or just get better trap speed? Because we dropped half a second off our times by cutting the 60 ft down .2.

what rear end do you have? i may have missed it like the tire thing

[Tom N]

3.9 vlsd from a n/a z32 or maybe a J30. Forget which it was from.

[Sforteen]

Tom is right guys.. radials are steel belted construction. bias ply are nylon.. hense why they hook better.. more flex.. radials are harder on drive train parts because they don't absorb shock nearly as good.. radials drive better on the street..
Tom I got you.. fuck these retards

[down_south240]

Thanks, I think we already established that after a bit of confusion on my part. Hence what I said about some people using the terms interchangeably.

[db_s13]

3.9...give the 24.5 a try but if you decide to up your rear end ratio you will also have to extend your redline or buy new tires again... i assume your not running a s15 6 speed

I have no interest in upping the rear ratio. Will kill gas mileage.
S15 trans went bye bye long ago. It has a regular SR 5 speed.

[s13 drifta]

To those of you running Weld rims, what length shank lug nuts are you running? Are you guys running stock wheel studs?

[Tom N]

1 3/8in shank. You should use a stud that's a little longer than stock.
Convert to a m12x1.5 stud. Easier to get the lugs for welds in that size/pitch then the 12x1.25 Nissan uses.

[s13 drifta]

I was hoping I could use the stock studs because I daily drive the car and I have a different set of wheels for the street. I did find the shank lugs in 12x1.25, so that's not a problem.
