What size slicks?

**TheKitchenSink** · 10-06-2008, 04:58 PM

Just bought a set of Prostars. 15X10 w/ 7.5"BS for the rears and 15X3.5" on the fronts. Need to figure out what size tire to order now.

As far as my rear end goes, I have a 12 bolt with 4:10 gears.
Engine/Transmission (A4) wise is... 3200 stall, transgo shift kit, tsp228r carm, Patriot LS6 Stage II P&P Heads + all bolt ons.

What tire would you all recommend I go with?

Do I need a little spacer on the front? or will they clear.
I know I have to do some grinding to get the rears to fit.

Thanks!

You have more than 'some' grinding to do on the rear.

And yes, the fronts will clear with a 5/8" spacer.
I run 3.25" ARP wheel studs for those wheels.

How fast does the car trap in the 1/4 mile?

I havent ran it yet this year, but last year before the heads and rear/gears I was 11.9 @114

Thinking 117-118 then?

Yea, somewhere around there I would suspect. Not sure how much the 4.10's are going to add over my stock 3:23's I had before

Shit...forgot to ask.
What RPM to you spin too?

And what brand tire are you looking at?

**TheKitchenSink** · 10-06-2008, 05:53 PM

Im pretty sure im set to 6700 and Mickey Thompson

**Mr. Luos** · 10-06-2008, 06:00 PM

Okay.

A 26" tire will get you to 126MPH at the top of 3rd.
A 27" tire will get you to 131MPH at the top of 3rd.
A 28" tire will get you to 136MPH at the top of 3rd.

You will probably want a 26" tall tire. 10.5 to 11.5 wide.

DOT tires? Or straight slicks?
I run a 27x11.5x15 Hoosier QTP on my 15x10's. Love them so far. Cutting 1.68's bogging.

Im going to go w/ straight slicks, the tires will only see the street. See if I can blow up the trans

Alright, I will go w/ 26" I wont have any issues w/ an 11.5" tire in back? I was getting a 1.74 60' w/ my nitto drag radials. Not to bad.

**Mr. Luos** · 10-06-2008, 06:14 PM

I run the 11.5" Hoosier's. Great tire.
They clear, but it is tight in the wheel well. I am sure some cars would need some hammering.

**TheKitchenSink** · 10-06-2008, 06:16 PM

Alright cool, maybe I will go w/ a 10.5" just to be safer. Thanks for your help!

For the skinnies up from, at the MT Sportsman 6651's what I want? It says minimum rim width is 3.5" which is what I have. Just making sure before I go buying them!
