I have a 17 front 16 rear CCW Drag pack, looks like 16" tire options are drying up.. I ran the MT ET Street 26x10.5x16 last year and liked the tire. Was hoping to run the MT ET Street r Bias this year but they don't offer it in a 16..

The only thing I can find in DOT approved Bias is the M&H cheater slick:

I also see a hoosier QTP option but it definitely is too narrow:

We've tested 26 x 11.5 x16 Mt et street bias ply tires as well as the 10.5's and 17's. many years ago in a manual c5s and the comparable M&H.

The conclusion was that the 16's hooked better and the MT was noticeably better than the M&H and more stable.

The 17's were more stable than 16's esp.without skinnies up front which is not recommended but stuff we used to do when learning about the cars and tires.
This was with aggressive high rpm launches.

The 9.5 Hoosiers will hook too.
Been 1.3's on an 8.5 Hoosier on a 10.5 rim.
You can stretch them no problem.

Ya the MT ET street is no longer offered. Which tire would you recommend I go with for a 16x10 CCW? Have 17" Bias ply front runners as well. I don't mind stretching the tire but want it to look good as well that's what I was worred bout with the QTP plus I plan to drive to the track on the tires.

I am in the same boat, I had the hoosier DOT radial once before in an 18" and they worked great on no prep but I was always worried about breaking **** with the stiff radial launching hard on sticky track. Rather be safe with Bias Ply's

That hoosier is pretty soft for a radial and will wrinkle too. Since its narrow and light it will be better than most radials and safer for launch.
Bias is much more predictable but with that tire I'd launch lower and give up some 60' but you will make it up on the back end. It will fit a 10" rim and give some extra gearing. Just experiment but its a player.
All of our autos saw 1.3xs and the manuals 1.4x.

Just want to be clear you are recommending the Hoosier DOT Radial (255/50/16 - 26") over the hoosier QTP (26x9.5x16)?

I am going to order a pair today for a no prep race sunday but plan to run this car at the sticky end often this year with the same tire.

I really appreciate the help!

Just giving feedback on the tires I've used.

I'd like to know more about your car and the venue to decide.

I raced my 02 Z06 (full bolt on + cam & 150 shot w/ same drivetrain setup as current car) a lot two years ago(attached pic) that was with the MT ET Streets and I ran a little higher tire PSI (20 hot) to initiate some wheel spin instead of dead hooking, launched high rpm still around 6500 and put probably 40 passes on the car like that and never had issues. I have too many expensive hobbies that also take up a lot of my time so I really prefer the setup be safe and run good vs on the edge of breaking to run the best number it can.

for venue, I am in middle GA we have a great local 1/8 grudge track that is always prepped well, this is where I usually go however a friend of mine who does all the local race promoting has moved from this track to our other local track which is 1/4 and not prepped nearly as well but he does no prep style events which I like racing in. He used to do no prep events at the 1/8 track from the shut down (completely not prepped asphalt side) but at the new venue he is running from the 1/8 mile stripe to the 1/4 stripe off an arm drop so it has some prep down. We also have a great 1/4 prepped track about 2 hrs away. I plan to race several of his no prep events but also want to do some Friday night TNT's from the prepped side & really try to get the car into the 6's on motor.

I am kind of thinking it may be smart to get a full slick for the prepped nights and the DOT radial for the no prep events. I have a tire changer at home so I can swap them out fairly easily between events.

robz

In an event I'd run a slick esp. no prep.
Those radials will be great for a prepped track when you can experiment with the launch.

I had a similar decision running a MIR World Cup Event. I knew the radial would produce a better et but ran the slick instead for consistency esp. with the pro tree and 2 step.

Here's a Hoosier 8.5 x 15 x 26 on a 10.5" rim.
High rpm launch, adjustable clutch, great track prep.

Thanks for sharing.

So for a bolt-on car warrior a Hoosier QTP is a good solution?
26 x 9.5 x 16. Would I need a 10" wide wheel or do you think I can squeeze it on a 8" for an ultimate budget setup (f-body wheels).

Tied of spinning my autocross radials to 1.93x to 2.0x 60's at the track in my 6spd FRC bolt on car. Thank you!
