So I got tired of trying to hook my 19s from a roll and need some help with tire choice. I ordered a set of CCW classics 17 x 11 rear and am in the age old 26" or 28" tire choosing nightmare. Currently I run a 305/35/19 NT05R which is roughly 27.5" tall and decided to make the switch to an MT as the car only comes out of the garage for races.

My car is cam/V3 making upper 600s at the wheels. I also have a TR6060 swap.


So do I go to the 305/45/17 ET Street R which I've seen people measure ~27.5" or the 275/40/17 and pick up a bit of a mechanical gear reduction?


I plan to add a set of AFRs and an MSD intake in the next month or so as well if the added power from that will make a difference in the equation

Mickey Thompson's website lists the 305/45/17 ET Street R as being 28.1" tall. Have people physically measured it as being 27.5"?

a few guys in the C6 section have said they measured it under 28" on an 11" wheel

I suggest M&H 325/45/17

That's a wide wheel for a 305. I know stock Z's come with 305/10.5 inch wheel. I'd be curious as to the height on C5z fronts, which are 9.5 inches.

Ben, I thought you were running this setup?

Definitely disappointed that they discontinued the 295/45-17's. That's all I've run in my vettes, street/strip. No need to change to hit the track. Mine have ~75 miles and no passes so the new owner will have the last set.

Mark,

For the street and runway: 18X11" wheel with a MT Street SS 305/40/18. It is 28" tall.





At the track: 17X10" wheel and with a Hoosier 28X10" slick.

haven't measure my ET street Rs but I can say I was dead hooking 760whp from a role with 19" nt05r with a nice burn out. but not05r had no hope once the car was >850whp. ET street R is huge step up though of course and if they are hot can hook up 3rd most of the time at 900/860.

I was tempted last time to buy the lower profile Hoosiers and get an effectively lower rear gear to wind out 5th gear a bit harder but did not hear a single good review using the hoosiers on the runway.

How do the ET street SS hook? Any traction around 40mph?

I wouldn't touch a m&h. Buddy of mine can't hook to save his life with his built c6. The r is an amazing tire, so is the s/s. Either will work great, all depends on the size you need. Hoosiers work good but they are much less stable at high speeds on the street.

Turbo-Geist

How much power are you needing to hook at 40mph? Which gear will you be using?

Here's a 60 to 161mph pull against a built ZR1 with nitrous.

Turbo-Geist

Which ET Street Rs are you using and what wheels are they on? Any pics?

I'm currently running a 35 on an 11" wheel and the sidewalk sits nice and doesn't look stretched. I know MTs can run a bit wide as well I figured I'd just repeat the setup.


I ran the 295/45/17 ET streets on my FBody too, they were the perfect tire

That looks perfect


With my NT05R at 20 psi, with a burnout they are spin city when the blower ramps up from a 60 roll in 2nd

I always went from 3rd gear in a roll and doubt the nt05r would have hooked 2nd ever on this car on the street/airstrip. my setup is pretty torquey.

I'm running 305/45/17 et street R on old style zr1 rims and they fit fine on my z51 car with z06 rear fenders. they are tucked in a bit but it helps them from rubbing when squatting.

we put my old hoosiers on my buddies 630whp car a long time ago and he could dead hook 2nd easy though at airstrip so I'd think something even stickier like an ET street R on a 680ish-whp car should be able to hook 2nd easy

Turbo-Geist

Do you have any pictures of this setup on your car? Which Z06 fenders are you referring to? Something like L5s or the TPS Flared?

He has a C6 not a C5
