How much of a diff. is there between the 2 tires. I was thinking if it was not that big of a diff. then i would go with the et streets so if i decide to drive the car up to the local shows(about 10 miles) i would not have to switch tires. Or could i just drive it on the slicks since its on 10 miles at 35 mph? Thanks agiain for dealing with my dumb questions.

The ET Drag has a softer compound I believe. I used to run a 26x10.5x15 ET Street and the 26x10x15 ET Drag is suprisingly bigger. If you're looking for more consistency and better traction, go with the Drags. If you're only driving 10 miles, then I wouldnt worry about it. Now some say that when you drive slicks on the street, it takes its toll over time on the sidewall. I guess you just have to decide what you really want most. I dont think it will have that much affect to hurt your 60 ft. by driving them down the road to your local track.

Driving around with slicks hardens them.

ET Streets don't work as well but I did cut 1.50-1.55's on mine.

Thanks for the opinions..i'll prob. go with the et drags. How long do they usually last at the track?

Depends how crazy you go with them doing your burn out. I'd say around 40 or so.

ok, thanks for all the help. i appreciate it.

I have gone a best of 1.44 on ET Streets and a 1.27 on a ET Drag.

This is my experiences. These tires weren't at all the same size and that does have alot to do with it.

HOT ROD magazine May 2004 did a test between 275/60 15 ET Streets Radials vs. ET Drags and the ET Streets cut a quicker 60ft. time and overall time.

ET Drags 12.5lb air pressure =1.597 60ft.

ET Streets 15lb air pressure =1.519 60ft.

According to Mickey Thompson do a burnout to raise tire temp no more than 25 degrees higher than the temperature of the track surface. Any hotter or cooler and the tires grip less. During burn out keep tires spinning long enough to get some smoke going. If tires look shiny and greasy afterwards you have got them too hot. A good tire pyrometer or infrared handheld temp gun avaliable from Radioshack $50.00 works good at measuring track vs. tire temps.

thanks for all the info. I think with having about 1600 hp, the et drag is going to be a better choice for me...i think it has alot to do with your set up as to what times each will make

The hot rod test was between et street radials and et drags wasn't it

I have to make a decision soon to.
My et streets are worn out. I can't decide between et streets and et street radials

Yes, the Hot Rod test was between the ET street radials and the ET Drags. I would think that a higher horsepowered car than the '72 Nova they were using would turn the test around, as the stiffer sidewall on the radials would be detrimental. Bob

Hot Rods 71 Nova was powered by a "600-plus-horsepower" Bill Mitchell Hardcore 454ci small block crate engine, a B&M TH350 with TCI Super Streetfighter converter (3500), and 4.11 gears. Best overall time between the two tire types came using ET Street Radials. 11.30@117.51

The ET Street "radial" design wrinkled less and launched harder than the "biasply" ET Drags on VHT prepped track.

My 255 50 16 ET Street Radials don't hook nearly as good as an ET Drag. If those test were conducted on a track that was super prepped...then all the tires will be close...no prep ET Drags will run away from the radials.

Onfire,

Verygood! Track was prepped with VHT during test.

I wonder if my local track techs would appreciate me gettin out of my car after a burnout to check the tire temps

That's b/c the 26 x 10.5 x 15 et street is measured by section width, not actual tread like the et drag. The 26 x 11.5 x 15 et street has the same measurements as the 26 x 10 et drag.

The major differences between the 2 is the et street has more cords in it for a stiffer sidewall, and that along with the grooves makes for the DOT stamping. I've gone 1.48 60 foot on my 27.5" tall x 9" wide et street (listed as 28 x 11.5 x 15) on my Nova on a 100 hp shot of juice, FWIW, and they still drive decent on the street, although I air them up to 22-25 psi for street driving.

That's funny, b/c I have a a 383 in my Nova making 75 less rwhp than their 600 hp engine, and I'm running at similar weight with less gear and my best run is 11.37 at 117 mph. Kinda makes you wonder about the hp ratings these companies give out?!?
