LSR Tire Recommendations Needed

[jacksoni]

I'll go along with what Glen and Bvillercr say for sure. However I think cars spin because they lose traction- lots of power, not much traction. Especially short, rear weighted highpowered roadsters.  I don't know what Dynoroom used on his bird but Gary Eaker had some sort of wide tire on his and went straight with near 300 times also.  Am not sure the specific loading of a narrow one on the salt is better than a wider one or some other advantage, but mostly think the wide tire is an aerodynamic downside due to frontal area and yes, you won't see on a lakester-usually- depends on whats available and where being run. Not sure a magic answer. I posted the link more for the surface/traction info and thoughts than the tires per se, but I surely agree different strokes (tires) for different folks.  Sort of like the locked rear arguement. If you spin with a locker, put an open rear in it. If you spin with an open rear, put a locker in it!

Try it out, then go from there.

We have more power than most and we don't have issues with tire spin in 3rd or high gear.  I just wonder what kind of set up the cars that spun had?  Rigid or suspended and how stiff if suspended.  Looks like we have a good set up for our car.

And a lot of it is lack of seat time under the conditions of the salt. It's not a drag race and takes a soft foot as well.

Ahhhh, does Mrs Boyd Coddington and associated fiascos ring a bell?

Wide tires work fine on pavement like Texas Mile, Maxton and Loring.  Wide tires on salt can perform as though they are hydroplaning - even when the salt is perfectly dry.  All those guys who tried them in the past provided enough "corporate knowledge" to suggest that the narrow tire is the only way to go on salt.

really, so how does a car go 285 in the first timed mile if the tires are hydroplainning?

DICK, I'm waiting for a response?  Anyone want to take a crack at this?

  Have you been working with the Propster??

are you speaking of Dick, Sparky?

[fredvance]

Dick is probably on the way to The Texas Mile.

Naw man---I just KNEW you had to have some secret weapon to get them big ole fat tars down the course and I figured it must be you have them "on step" and are planing on down the course pushing them with a prop    ---- 

[bvillercr]

The difference is that I can back up my claims.

[Peter Jack]

Yeah, but that spoils all the fun.

I am not much of a pro, having only run one year, but  narrow tires and a whole lot of lead is the way to go.  I ran my 1990 ZR1 with 4.5 X 28 X 15 in the rear and about 2000# of lead with 640 Hp and it ran straight and true to 219 mph.  tried removing 100# from the rear in an attempt to go faster earlier. And things got way loose once I was over  215,  on the salt weight is definately your friend.  Also one of the  things I learned was that its still a drag race, and you need to hook up early if you want to get to 230 plus you better be going 215 by the  2.25 mark, as a whole lot of track goes under the car every second once your at speed.

my comment after my first run was man, 5 miles is short:)
 
Good Luck
