Slick size recommendations

[Rolling Thunder]

have a 63 dodge with stock width Dana 60 (1969) with factory perches and factory wheelhouses. Also have 15x8 steels with 4.5 backspace. Any recommendations for size of slicks can run?

 

[silversedan]

probably 9x28 depending on your gear ratio. if more room by front lip , taller one's. make sure you check the section width's listed by the manufacture.

 

[Rolling Thunder]

Thanks. Gear ration is 4:10

Is your combination posted anywhere? I like to do tall tires and lots of gear but so long as you can air them up a bit so you don't get much flex from the sidewalls, tall tires work well. Need to know more about your combination before making a recommendation though but it sounds like a 9" tire is going to be about it with an 8" rim.

Running around 550 horse big block with auto trans (3500 stall). Rear is 69 Dana 60 with sure grip 4:10. All steel body panels and full glass. Subframes connected. If need any more info just ask.

I wish you were closer. I have a set of 29x9s in the garage mounted on cop wheels. You could try them out. I'm not real attatched to them........

I run these 30 x 9 Hoosier radial slicks in my stock wheelwells with my springs in the stock location. I use 4.30's with a Dynamic 9.5 converter. My eng is a mild 493 making about 600 flywheel hp and I race through the full exh on pump gas just as I drive it. To be honest I feel it might be faster with less gear as I would love to go to 4.10's or 3.91's as I feel it would mph more and pull the lower gears fine. But you can fit 30" tall tires in my stock wheelwells. With your 4.10's I would run somewhere between a 28" to 30" tall tire depending on the eng and converter. Ron

The question to answer is what your racing 1/4 or 1/8 or both. Since you know your gear ratio, the size of the tire will dictate the rpm through the traps.

 

[Rolling Thunder]

Probably a little 1/8th but mostly 1/4.

My friend runs 9x28 0n his 64 Polara. It weighs 3775 has S/S springs and adjustable Rancho shocks with a 4.88 and a stock stroke Hemi. With tuning we've been able to make it pretty consistent in the 10.60's

I have 11.5 x 28.5 Phoenix on my 1966 Satellite now with a 4.10 Dana. However I just installed SS springs and moved them back 3/4" to give clearance for 11.5W x 29.5 Phoenix (really 30.5" diameter). The 11.5 W's are 13.5" on the face. I had great luck with those years ago. I'm sure with 550 HP you need as much footprint as you can fit to get consistent results.

I ran 9X29's and 30's, with 7" Cragars. I had about 650-700hp, and a 4.10 gear. It always hooked.

That's really good.

Weight transfer helped! LOL

 

[66Satellite47]

Great looking launch. Since it looks so even side to side you must have a really good rear spring set!

 

[mmissile]

Thanks. I had "old" S/S springs and low pressure[individually adjusted] airshocks. No pinion-snubber or any other tricks. It just flat-worked. I got lucky, I guess.

Like 383man I run 30x9 Hoosier radial slicks. They were recommended to me by a friend that has raced for a long, long time. I've raced at about seven different tracks in different weather conditions and they have never let me down. I like the ability to run higher air pressures. The car feels more stable, especially at the big end. Hoosier makes what they label as 9x30 radials but with two different circumferences. I run the smaller 92.5 circ.
