MT Tire Pressure Altered/FC

just got a set of M/T 34.5....can someone give me a ballpark on the pressure....beadlocks, no tubes. hoping someone out there sees this with a blown altered/fc
thanks,
Darren

 

I has the best results on my dragster with the MT 3186 tire using 6.25lbs


GK www.MotorSportsInnovations.com

 

With blown BBC and glide we went .985 60 1.80 trans 4.30 gear

With blown fuel hemi 28 gal pump and 38% 1st and 3.20 gear glide clutch 1.00 60ft

NFC legal 38 % 1st and 4.10 gear glide clutch .974


Each time we ran 6 7/8 lbs with M/T's and beadlocks.

 

6 3/4 on a promod 2300 lbs .946 60'
beadlocks

 

How about the "Bubba" tire, 3190 with the stiff sidewall????

Thinking 6.75 to 7

Hemi, screw, Bradco 400, 1.40 and 4.29 rear at 2700lbs

 

thank you everyone for the replies. We are switching from the 2055 Hoosiers, car ran .950-.980 almost anywhere.....looking for a little more wheel speed. clutch car, 1.89 low,4.30 rear, 526 hemi-roots. just trying a few new things and want to be close on this as we will be on a limited run basis.
thanks again,
Darren

 

Go with Goodyear N/FC spec tire, it will get up on the tire quickly but doesn't kick them loose @100ft as easliy as the M/T's

 

Go to tubes and liners and get rid of the beadlocks if you want to increase your wheel speed.

 

thanks for all the replies......I am not looking to change my whole program by going to tubes/liners......just wanted to know if anyone had a similar combo and could give a starting point. thanks again for the replies...going to start with 6.5 and go from there

Make sure you measure the rear tire circumferences. Altereds are not very forgiving in that area.

Does GY make a particular NFC tire?
What`s the tire code for that tire?

Thanx,
