I'm limited to running a 15" wheel and wanted to see some of the best times people have ran using a 24.5" slick on a 15" wheel. Thanks.

 

4 years ago I went 11.01@132mph on 24.5x8.7x15 M&H slicks in my ITR. I never got a clean pass without clutch slip so I know there was way more in it. Im going back to that tire next year.

 

Were you able to fit those slicks under the stock fenders? Did you use coilovers to raise the car?

 

I like my toyo 25x9x15's, they seem to hook pretty good. Best I went in my 450whp 2500lb street car was 11.06@126, not the fastest time out there but not shabby.

 

Couple of major factors that are going to have an impact on times are going to be Weight and Hp/Power Curve

As we both know VW's tend to be heavy with high tq to Hp numbers. This makes traction even hard to find when pushing the limits of the tire.

That being said I've cut numerous 1.75 60ft's and gone bottom 11's on ~12lbs of boost.
24.5's on 15" Rotas.

I weigh 2580lbs in my mk3 jetta.

I am sure you have seen but Tim from Md went 10.8 in his 2600+lb gti on the 24.5x15 on stock wheels.

I'd say lower 10's are definitely possible on the tire. 9's might be possible but you would have to work real hard to get it done.

As someone else mentioned the 25x15's are supposed to be good as well.

 

10.62@137 60ft 1.64 on 15/24.5/9 on a stock bore b16 I've seen 10.09 with same size slick also

 

My best was a 9.77 with a 1.54 60 foot time on Toyo 25X9X15. Great tire BTW..

 

i have went 11.3@125 on a 23x7x15 so you can defentially go faster w a 24.5x8.5x15 for sure

 

I wish that tire was legal for true street.

 

I ran them on stock suspension but I got coilovers and made a world of difference.

Just swapping the suspension out and launching harder(stock stuff made the car handful on the 1-2 shift) I went from a 11.6 to a 11.07. The car was about 550whp and 400wtq and 2800+lbs. If I remember right my best 60ft was a 1.64 on coilovers and 1.76 on stock suspension

 

What are the tire rules for true street? I know most racing bodies allowed 25" maximum.

 

i think mb racing or someone up north ran a high 8

 

true street is 24.5" max

 

Yeah I wish it was 25" though

 

Thats lame! I dont run true street so I have no room to complain, that just limits the tires that racers can run. Toyo's are very reasonably priced as well.
I have emailed toyo with interest in a 13" tire but have gotten the typical "we will look into it" reply. Maybe with enough interest they may develop something, the 25's are great!

 

on a 13" rim and it was Felix Medina

 

my tired old b16, launching at 8800 ( no antilag) single stage boost control went 10.72 on 24.5 x 8.5 x 15 m and h's at probably 2600 lbs.

I suck at embedding videos.

 

niceeeee

 

I run the same tyre and managed a best of 1.72, I would love to run a 1.54, that is hauling ***, what tyre pressures do u run and rim size?

 

The rim was 8.75", Tire pressures were around 6psi. Super stable up top
even with so little air.

My 2nd favorite would have to be a Hoosier, get em hot and they stick as good as a MT
and last 10 times longer..

Thanks for all the replies! Seems like 1.6 60's are common with the setup and 9.8 is the quickest ET I seen so far on the thread.

 

Beat me to the Tortise car post, that was the first car that came to mind when I saw this thread, lol!

That car is hella imperessive.

 

I went 8.8 @170mph in a fis legal trim 62mm honda civic 24.5/8.5r15 tire
