another tire question

[flips72]

i finally got to take my truck to the strip last night and the old girl done allright considering i was onn street tires, 7,82 at 85.69 mph, now ineed some traction, anybody know whats the best tire combo, drag radials for a stock suspension 65 with factory tubs? right now i am running a 255/70/17 toyo proxy all the way around but it was blowing the tires off. i will probably go back to 15 inch wheels because i want to run at least a 29 inch tall tire and theres not anything in the 17 range, or at least that i can find. thanks for the help.

Pretty impressive. The mickey and hoosier drag radials are pretty awesome.

thanks kevin, love your truck by the way and the pass time video is awesome. ithink i have decided to go with a 275/60/15 on a 8 inch ralley and just swap them out for dragstrip use. from what i have read they are arond 28 inches tall and what i am running now is 29 1/2, so it will even help with the gearing since i am running 373 gears now it might help a little,dropping a 1 1/2 i know not much but every little bit helps.

Thanks Flips. Good luck. Let us know how it does.

Here is a video my brother took on his phone at the dragstrip.

Nice truck.

What rpm were you crossing the traps?
What gear ratio is in the rear?

Using a 28" or 29" drag radial might actually be slower than a 26" the effective gearing change between the 26" and 28" is pretty big. Similar to a 3.73 to a 4.10..

just had changed into drive when i went through the traps, i am running 373 gears and a 29 inch tall tire right now, i just ordered a set of 275/60/15 drag radials which have a advertised height of 28 inch on 8 inch rim, i am shifting at 6000. hoping with the drag radials i can get on the converter more ,maybe that will help some too.havent done alot of drag racing in a long time kinda forgot what little i knew. read all the way through your build a couple nights ago, all i can say is awesome.thanks for the reply always open to suggestions.

I've been running MT ET Street Radials on my truck. They are plenty sticky for my setup. 275/60/15. Try em, and you'll never go back to anything else for street/strip.

Don't bother with the Nitto DRs....useless.

allready ordered the goodyears, they came in today, hopefully they work probably should have went with m/ts, oh well i will let yall know in a couple weeks, should be ready to go back by then,trying to fix a crazy oil leak right now, anyone have any trouble with the one piece blue felpro oil pan gasket, cant seem to get it to seal off for some reason.

Do you only run 1/8 mile?

If so you would most likely go faster on the 275/50 being a 26" tall tire. Like mentioned the change from the 28" to a 26" would be like putting a 4.10 gear in your truck.

Either way you will probably be going faster than what you were.

If the GY DR's are anything like the MT DR's they need a pretty good burn out. I hit the tires, shift in to high right away, bring it to about 5,500-6,000 and hold it there and count to 4, release the line lock and roll out half throttle till they grab and the truck lunges forward. Counting to 3 is not enough most of the time, but 4 seems to be the magic count.

I agree with what Super73 said regarding a 28 vs 26 inch tire.

My truck responded to the 28" tire a lot better than the 26" tire though, because it loaded the engine harder, lighting the turbo faster.

I have heard the Goodyears work good . I think they never got a chance when the new style M/T's came out .

yeah, we only have a 1/8 mile track close its brainerd optomist in chattanooga,about 45 minutes from the house.eventually i would love to have a 4.56 in it but that will be if i decide to go 9 inch, then all i would have to do is a center section swap, i was kinda worried about the truck rearend holding up but i noticed in your thread you are still running one so the must be tougher than i thought, are you running a trans break in your truck or foot breaking.thanks for the info on the brunouts i am sure that will help.

thanks wasted income for the input, my brother just put a 76 mm on his 6.0 in his 67, havent gotten the injectors or tuned it yet but we are hoping for big things with it.

just a update on the goodyears, finally did get to go to the strip and see what they would do.consdering the track was in poor,poor shape the tires almost held once and it went 7.81at 84.72 my 60 foot just bearly dropped from a 1.706 to 1.648 that was at 22 psi. now the trouble side showed up, trans started slipping in drive so now i guess i get to build a tranny.oh well i was getting bored anyway lol.
