I'm running a 28x10.5x15 and wondering if i should go to a 29 tall slick.

you give no detail for your question to be answered.


rear gear?
trap speed?
rpm at the stripe?
gear at the stripe?
60'?


but probably a 29" is too tall

Sorry my bad. I'm going through the traps at 116 mph. I have 4:10 gears and a T56 Magnum six speed

Did you upgrade your axles?

slickman

Yes upgraded them to moser.

Just ordered a Race Star wheel package from Brenspeed, 15x10 and 17x4.. Going to put my 28x10.5 on the rears. And I can sell the new set I have then get some new 17 tires for the new front skinnies,..

I have 15 all around and the fronts are 15x4 (New, 2 of them) and 15 x 8 (secondhand). Got them both about a year ago, Comes worth the spacers to they will fit on a s197 sting. I already had them down the track with my car, no problems at all, straight as an arrow..

The rears will not have any tires as the have been mounted on a wider new rim. So, everything, 2 front skinnies 15x4 and 2 rears 15x8.. $300 plus shipping..

With a 116mph trap speed I would probably go to a 26" tall slick. Just my .02.

26? I would run out of motor (in 4th) before the traps.

Assuming that 4th gear is a 1:1 ratio in your transmission, at 116 mph you would be turning appx 6100 rpms at the stripe in the 1/4 mile. On a slick you will get a little bit of growth as the tire reaches higher speeds, so the actual diameter might be closer to 26.75" as you go thru the traps which might put you just a touch under 6000 rpms. Should be perfect.
