Best slick for an irs car?

[SOVACobra03]

I'm going with a 28x10.5x15 slick for sure but idk what brand. Also what's this about stiff side wall that some have? Thanks.

I would run a MT Et Drag. I run a 26x10.5 Et street on 16's (they dont make the ET drag in 16"). And I am really happy with them. I can only imagine that the ET drag will hook up even better. I am around 600hp and they hooked pretty well.

I have a set of 4:10s in mine so I'm really wanting the taller tire to open the gearing up a little. At the top of 4th at the end of the 1/4 right now. Not sure my power level but it was about 600 before the extra 2psi timing and e85

Mt et drags are what I'm leaning to right now though

Yeah with 600+ and 4.10's you will want a 28" tire for sure.

I do agree and I appreciate the advice

I'd guess 99% of us run MT ET Drag 28" stiff sidewalls. I've been through at least 5 sets myself and love them.

Any one run hoosiers?

What width are you running?

 

[Posi]

You want the tallest tire or the tallest sidewall you can get for the IRS so it helps absorb the shock of the launch and hopefully saves the halfshafts. That's why the 28" slick on a 15" rim is by far superior.

That's why I went with 15x8 RTSs. Wanted all the side wall i could get lol

28 x 10.5 x 15s

Smart man lol.

Don't get me wrong people have great luck with 26" tires but in theory the taller the sidewall the more it helps the IRS live or the halfshafts themselves at least.

You running those on an 8 or 10" rim? I want the taller for the shock absorbing effect and to help me on the big end. I'm literally on the bitter end of 4th now when I cross the line.

With the IRS I ran 10" wide Bogart's.

 

[SOVACobra03]

With the IRS I ran 10" wide Bogart's.

Hummm. I wonder if there would be any issues with 10.5 wide on a 8" rim?

 

[SOVACobra03]

Also do I need tubes in those? I'm totally new to the slicks game

 

[Posi]

No sir I never ran tubes. Then if we used any (I will not say I recommend this lol) lube on the rims during installation it was very minimal. My car weighs 3,850lbs+ and after a few runs with new slicks they typically never move on the rims at all. It's a transbrake car too and it is used lol.

Now if you use to much lube for installation like I've had someone do unknowingly each launch the tire will move on the rim. Sometimes up to 2" too! Or at least mine did.

 

[Posi]

They may leak a little but meh who cares? I have one that holds air basically forever and the other leaks slow. To me it's no big deal.

 

[SOVACobra03]

Haha its not like they are street tires and not like I won't be checking the air in them before I start making runs anyways
