who DD on drag setup?

[travelers]

That's what I was pretty much looking to hear thanks.

Is you car a stick shift or auto? I'm asking because i'm running 275/60/15 pro on my car (stick shift) I know what people say about manual transmission and DR don't go together. Is a bias ply really necessary?

On our full race car which is stick, the slicks we use is bias only. Radial slicks don't work well as the sidewalls are to stiff.

Mine is auto- Yes a radial isn't optimal for a stick shift- at your power level you are at about the max for the et pro with a stick still being a "good traction tire" ,Auto cars can run that tire into the low 7's in the 1/4 mile.
People also say if you have a BIAS tire in the REAR you should not have a RADIAL in the FRONT. High speed stability-(???) Someone posted a concern about braking- I can assure you from 140< to 5 mph I haven't had a issue and at 55mph on the average 2 lane highway, or 75 on the interstate I haven't had a braking issue, But I do drive for conditions, and drive appropriate for how the vehicle is equipped. My chassis and suspension doesn't deflect so it makes the car handle better than if it was on stock suspension and just skinnies- but as I stated before the key to street driving a skinnies is the 10 ply(MT)- they just don't flex and roll like a traditional skinnie- I guarantee if I have a normal skinnie and drove like I did with the 10ply the tires, they would of left the rim(s).

Thanks fellas!

Mine makes probably a dozen or so passes a year. When I stab it it is usually on the street and I probably only do that a couple times in a tank of fuel. Yes with little to no traffic and in as safe a spot as I can find.

Kind of a pita to drive home, change out the wheel setup on the rear, go step on it, come home and put the all seasons back on. Who does that? Seriously.

Also I notice that skinnies are $200 a tire which I think is too much money. Can I run a regular tire that's the same size as a Mickey & Hoosier skinny? Here is a link to some that's in 17 tire size which is the size of my front runner. I believe the speed rating is 150mph on some of these which is more than enough for me.

You'd need to run them up around 42 psi in order to match the load capacity of the OE-size (SL) tires at 32 psi, so it's at least do-able from the standpoint of driving around on them on a daily basis. Might as well pick from the low rolling resistance ones while you're at it.

205/50's should be mounted on rims at least 5.5" wide - I have a feeling that they'd tend to wander around a lot more at speed if you tried mounting them on 17x4's than a similarly sized bias-ply tire would.

Getting caught in the rain is probably the worst situation for a narrowish front radial/wide rear drag tire combination. It's evil enough with 185 radial fronts / 215 bias-belted rears on a far less powerful RWD car (long time ago, but not something you'd forget).

I do that every time I go to the track. Depending on my schedule I sometimes put on the 15's and QTP's the day before and drive them to work, then to the track afterwards. I usually don't change them when I get home because it is late. Sometimes they sit on there for a day or two but I usually swap them out the next morning.

I drive to the track on street tires and then change the rear to DR's. I have a racing jack from Harbour Freight I use for that.

The only time I have driven a long distance on the DR's is when I take the kids with me since I cant fit the DR's in the trunk due to height.

Do you really need DRs on the street when you "stab it," though? Serious question. I don't know your setup.

I put the all seasons back on when I go to the track which is about twice a year. Gravel road. Beyond that in the summer I leave the welds on the car. Don't wanna deal with constantly changing things around just to go out and play a little bit - I'll pay the money for the tires. Call me lazy if you want.

If I want to experience the pull in lower gears absolutely yes.

All depends on how you drive the car and the weather. I drove home last night from the track in a rain storm with MT SR skinnies (expensive, but where else can you get a 28" tire that is a radial and fits a 3.5 rim?) and 275 60 15 street SS MT drag radials, and I really took it slow. Very cautious. But I always drive to the track (only 25 miles one way) with this setup and I've driven to a nearby town (100 miles round trip) several times. The worst thing is just how the car rides, imo, with race tires on it. A lot different from street tires. I ran Nitto 555 before and they last longer but I wasn't impressed with them for the track, or BFG drag radials either. MT is the way to go, imho. Driving habits and common sense.

Never ran skinnies but I've street driven drag radials many times. Over the years I've had a few fairly powerful setups and drag radials are/were the best option imo.

My experiences are as follows:

Nitto 555R- Nice street manners, still has a relatively stiff sidewall so it tracks well down the road but it's the least sticky DR. In fact it's really just a soft street tire imo.

Nitto NT05R- Another DR with a stiff sidewall that has great street manners. Sticky tread, my favorite DR for highway driving. Nice ride and does just fine in the rain provided the driver realizes there are limitations to a high hp car in the rain.

M&H- These were always the stickiest tires but the soft sidewall results in a little drifting at highway speeds. I've had them in a few sizes and both were the same at highway speeds. Never trusted them enough to dd with them.

Goodyear- I don't think they even make DRs anymore. These were 275/60/15. They didn't drift at highway speeds, rode great, nice tires but not something you would want to throw into a corner.

My take was that I already had so much money into the car why not run drag radials provided they were safe? I always felt they were safer than regular street tires during the warm months, they didn't break loose as easy as my "summer tires".

My suspension setup was fairly simple. LCA, UCA, softer rear springs, and a full length axle brace. My approach to my mods has always been that the car has to remain comfortable enough to dd. This is why I took a tubular k member off after 3 weeks. It made the car far less comfortable on the street and my car will always be a street car.

Well I only drive my car around 4 miles round trip every day. I own a 18 wheeler and I park it very close to my house at a storage. But I do drive it on weekends around town So that was my main issue. Not worried about rain because I only drive about 2 miles each way. On weekends if it's raining I drive my wife car anyway. Thanks for all y'all help guys!
