Tire size for my street/strip?
Okay, so I have an 85 c10 that weighs 4,000 lbs.
Motor makes 462 hp. @ 5700 rpm
465 Ft. lbs. @ 4200 rpm.
I'm running a 3600 nitrous stall in a built turbo 400 trans.
4.10 Gears in a truck 10 bolt. eaton posi.
dead hook cut a 1.8 60 foot
& went 13.16 @ 99 mph
i shifted at 6200 rpm 1st to 2nd, and 6200 2nd to 3rd. And i think when i crossed the line i was right at about 5000 rpm.
The tire i am running now is a M/T e/t street 315/60/15 which is a 30/12.4/15
So my question is should i drop down to a:
28/10.5
28/11.5
29/10.5
29/11.5
Or something different?
my trap speed needs to be higher, i really want to break into the 12's.
i might be able to shave another 100 pounds out of the truck which will help.
and i need a little better tune on my carb. but i defiantly need a different tire. I gotta get my trap speed up and a little bit less tire to have to rotate.
So what are your opinions? and if i need to post this in a different part of this forum please let me know! Thanks!

Yeah I do run mufflers. I do a lot more street driving than at the track. But I just want to be sure that if i go with a 28/10.50 or 11.50 that i will still hook okay.
Its got two leafs per side and traction bars for rear suspension. and beltech drop spindles and 90-10 shocks up front.

I pick up 3 tenths & 2 mph. Running open exhaust. The flowmaster was killing me. I run a m&h dr's 28x10x16. With a best 60' of 1.74, 1.8's or pretty regular, no traction adders.

I Have 3" exhaust that is straight pipe from the headers w/ no bends, super 44 flomasters, dumped before the rearend. Depending on how far away a tracks going to be from me now that Gateway International closed, I may have to try no muffs, and see if that helps too.

I can say this about the m&h dr's. they can easily be over powered. I will be getting a full slick soon for the track.. They do hook pretty good on the street.
