I spoke with Steve Hudspeth (very nice and very professional) @ Hoosier today to try and clear up some things in my mind about their 16x28 tires. Here are a few notes.

1. The DOT and the Slick have almost identical compounds. He didn't really see how the slick could hook better than the DOT. He said the biggest problem he sees is people putting alot of heat in a tire on a greasy track. Hot greasy tire and hot greasy track equals compromised traction. (Something alot of us already know but somebody just getting into racing may not0

2. He told me to just give the tire a little extra burnout the first time. I guess he doesn't subscribe to the 20 second burn and overnight cure theory of M/T.

3. His experience with the DOTs showed that 11-13 lbs pressure seemed to work the best.

4. Forget trying to take temp readings across the tread; they will never be even and only confuse you.

5. For the DOT tire he said 10-12 inch rims, but, 12 would give the optimum tire profile.

Just thought I would share w/everyone.

 

Hey,

thanks for the info.

When he was talking about tire pressure, did you remind him how much these things weigh?? That pressure seems low, but ???

thanks

I tried 12 lbs last night and spun a little and felt VERY uncomfortable at the traps.
went back to 16 lbs. and felt pretty good.
I still need more time with them.

RAN mine at 18 and ran 13.12 lowered it to 16 and ran slower and spun,looking at my tires the next night had nice peal on edges but still had the rubber tit nubs in center,tells me to much weight on tires not enough air,tire seems to be colapsing at launch so i think I'll start at 20# next time out

 

You said "tit nubs"

He was with a guy & an L down in Florida so i'm thinking he knows how much they weigh.

I like "tit nubs"....just not on my slick use pattern.

 

I run mine at 17 psi
anything under 15 psi and I am all over the track from half track on to the traps.

I borowed a set of the 28x10-16 slicks when I raced at FFW in Virginia. I cut much better 60 foot times and they hooked much better than the DOT's. I think it is the fact that the widest rim I have found is 10 inches wide and the section width is 14.5 inches. These two factors cause the tread to crown way to much.

I hate the new Hoosirer Quick Time Pro's

 

Don,
Stop beating around the bush and tell us how you really feel.

We have been getting 1.6x at 17psi with a 10in rim, at a slick track with ours.

Don...dont hold back any! LOL

what was the 60ft differance with the slicks vs the DOTS

jb

 

I ran mine at 14.5psi and had no problems hooking or on the big end. I could get 1.67-1.70 60 foot times as a average on my stock stall convertor. If you try 14.5 after you do a burnout they are around 15.0 and will do fine. Anything less than 14 and you will need screws & tubes....

 

The best I did was a 1.69 but most of the runs are in the 1.7-1.9 range. The set of 28x10-16 I was getting mid to low 1.6x 60 foot times.

I just ordered a set of the 28x10-16 so the DOT's are going back to hoosier

 

Don -

I think you are probably on to something with the rim size. I am looking at a custom 16 x 12 with 6.5" of backspacing. $$$$$ $$$ $$$
