So I plan to bracket race my street car this year, and am close to needing new drag radials. Never really had any issue with the 275/60R15 S/S ET Street Drag Radials, but they sure wore out fast...
Absolutely no chance of me running ANY bias ply tires, so no need to even discuss them

I run 15x8 wheels.

About the same money for my 2 choices , so that's a non-issue.

My 2 choices are both Mickey Thompson Drag Radials

1. 295/55R15 ET Street Drag Radial S/S

2. 275/60R15 ET Street Drag Radial PRO

#1 is DOT legal, #2 is not.
#1 "should" work and are an inch wider than what I have been running.
#2 is supposed to be a very awesome tire...

I DO actually DRIVE the car as much as possible, so that's a factor...

Opinions?

I thought about those 295/55's for mine. Wasnt sure they would fit though. I've run the 275 version all last year....Still have a ton of tread left at least 100 passes on them and alot of street miles. Surprised yours wore out so quick. I just do a quick burnout to clean off the tires and go though...

For bracket racing Id think either should work....for the 295's you might want a 10" wheel though...i have 295 50 15 BFG street tires and they are on a 10" rim.

Bob, I heard a rumor that MT is releasing a 275 ET Street R this month. Basically a 275 pro with a few grooves that is a real DOT street legal tire. I am running the 325 ET street R . when they actually get released is anybody's guess. If you don't care about Street legal , 275 Pro is a proven tire.

275 Pro would be my choice and have a set of tires for the street. I have used the 275 ET a lot on the street and they do not last.

I presently have FOUR rear wheels that match the fronts . All 15x8s.

Two have 285/70R15 BFG's, and two have the 275/60 ET STREET S/S drag radials.

Definitely not buying another $500 pair of wheels...

Bob trust me, I've been drag racing all my life and I know for a fact that the Radial PRO's are definitely the best on the market right now. :yes: When I went to the Buick GS Nationals with my GN, all the fast guys were running them….and by fast, I mean F-A-S-T…(7's in the 1/4 mile) :eek: The downside is that I don't think they're DOT approved and they probably won't last as long as other drag radials… but one thing for sure…They hook! ;)

Well, I guess the ET PRO is the way to go, and then just plan on swapping the extras on for cruising....

I actually meant to make this a 2 part question...with Part 2 being a gear question....so I'll add it here....

Car is 1/2 second slower with the 3.08 gears, which isn't a problem, and actually helps it hook....

Would you guys run the 3.90's and wring it out in high gear, OR...

...3.08 gears, barely hitting high gear, and lowering the chance of traction issues....while not beating on the car as bad????

What do you think about gear choice Rick?

I got no problem losing a half second, if it'll help consistency.

Any thoughts?

Bob…I think that 3:08's is low for racing and that 4:10 a tad too high… :eek: Have you thought of 3:50's or maybe 3:73's? One of these two ratios would be best… :yes:

Have you thought about these: https://www.summitracing.com/parts/nit-180490 Nitto NT555R 275/50/15. I'm very satisfied with mine, FWIW.

You seem to drive your car a lot.....which means you'll likely get stuck in the rain at some point. The MTs kind of s*ck in any amount of water.

What type of Bracket Racing do you plan on taking part in? Better to be the quicker car and do the chasing down.

If you had the 3.9s or 4.11s would be low 11s which over here would be the Fastest of the 'Super Street' DYO class who can go down to 11.0 seconds.

If its more consistent with those gears then leave it. You don't need another variable as traction to take you out. A drag radial is a little difficult in a bracket race since once it spins its done. There is no recovery. A bias tire will slip but you can still be in the race. So if it helps, I wouldn't touch the gear.

I looked yesterday but they weren't there, but today they are :D

Yeah, with 4.10's is where it ran it's best number ever, but it was staying revved higher than I like, for the last 300 feet or so.
3.73's aren't worth the effort IMO, since I already have 3.90's.
The 3.90's aren't bad at all, but occasionally, but not very often, it'll spin. In fairness, this is at a very sticky, usually very well prepped track, but on the off days, the guys get a little overzealous with the water box and then once water starts getting dragged out, then I seem to find it...The car has never spun with the 3.08's. Not enough torque multiplication, I guess.

Like I said, I'm not concerned with the car slowing down, hell it's not fast by most standards...but it IS actually more enjoyable to drive on the street with the 3.08's.

I thought about Nittos for my extra wheels, but definitely not for the dragstrip. I agree 100% that they last and are much deeper tread for the street, but I seemed to outgrow them a few years back. A shame since they are quite a bit cheaper...$225 vs. $150.

If you had the 3.9s or 4.11s would be low 11s which over here would be the Fastest of the 'Super Street' DYO class who can go down to 11.0 seconds.
Either Sportsman/Street class: 12.00-19.99, or
Pro/Heavy class: 7.50-13.99

Ironically, I've always had better luck being the one that is chased...the faster they are, the sneakier they are though, lol.

I've seen video's of you "driving" on the street Bob...no tire you can buy is going to last. :D
Whatever do you mean sir??? 0:)

That is why I was leaning towards swapping the 3.08's back in...it's never spun with those on it, at the track, and is right at that 12.00 limit without being one of those sandbaggers. I'd much prefer driving the car, consistently, and running the number I wrote on the window, as opposed to dialing in half second or more slower than I run, and playing the games at the traps.

And you're 100% right, if I do even spin a half turn, it seems to ruin the whole run, everytime.

ET STREET R

I've seen them in Jegs catalog, but they don't have a 275/60r15 in that tire.

I don't know why they used to have ET Streets, and ET Street Drag Radials, now they have like 6 or so different versions...it's stupid. I liked the ORIGINAL 275/60R15 ET Street Drag Radials...previous set lasted 2 years, with well over a hundred passes, and well over a hundred burnouts for fun...The S/S version are pretty much done in one season...36 passes total... :frown2:

Thanks for the replies guys...keep them coming.
