Sweet rides man.I'm diggin your truck.

 

[dragogt]

Love the car.

Thanks Guys!!

Quick question. I am new to tires this big and agrresive. The biggest tire I had in the past was some 32s. This truck has the 36-12.50-16.5 Wrangler R/T IIs. They only had 500 miles on them when I got it so I figure I might as well run them a while. So the question is...
What air pressure should I be running in them? Right now they have about 21lbs.

 

[LEB Paul]

I have the same tires and keep them between 25-30, but I don't put many road miles on the truck with those tires, so it may be different for you. I do think their max pressure is 30 though.

Oh, and welcome to FTF!

 

[Skandocious]

Great lookin' rides! Both of them look fantastic. Welcome to the site

Max cold psi should be on the sidewall.

 

[sivlersnake]

Yeah, I saw the max. It is 30psi. Just not sure if that is what I should run.
Thanks!!

 

[Truckin4life]

I run 10 psi in mine... Think i might bump it to 15 up front though...
Ive had these tires down to 5psi on the street. Little soft but they can handle it.

Sick car by the way. Love the 03 snakes. Only way it could get better if it were sonic blue...
Nice numbers also...
Any future mod's planned for the car?

 

[sivlersnake]

Thanks!
I'm done with the Cobra for now. I will try to dig up some motor pics when I can.

 

[Truckin4life]

What all has been done to it?
Is it just motor work or is there suspension work done?

 

[sivlersnake]

2.8 pulley
JLT cold air intake
MGW shifter
Magnaflow X-pipe
Magnaflow cat-back
H&R race springs
M.M. IRS bushings
G.M.D. trunk mat
Tinted windows and a handful of small dress up items

It normally does very well at car shows.
My friend gives my a hard time because I go so far as to wax the springs for a car show. lol

OH! I have a set of M.M. caster camber plates I need to find time to put on.

It is also very good at getting on the highway. lol

 

[Truckin4life]

Yea i dont see merging into freeway speeds being an issue...
2.8 pulley what kinda PSI does that put you at?

 

[sivlersnake]

Around 14 to 15 I think. I have not upgraded the gauge. It stops at 10.
Lots of fun to drive!

 

[Truckin4life]

Thats about what i was thinking...
I almost bought one a few months back.
But thought better that i didnt. Insurance would kill me.
So i will wait until im 25 then get a cobra...

 

[sivlersnake]

yeah. insurance is not pretty. New it was higher than a vette.

 

[Truckin4life]

Yea, vette's are much more common though, and vette's are not supercharged either...
Almost bought an 07 gt insurance cost more per month than the car payment was...

Weren't you complaining about bad gas mileage a while back? What a terrible idea to run your tires at such low pressure on the street. It'll yield bad gas mileage and make them wear in very weird ways.

Yeah but you never know when or where a killer rock pile or sand dune might be lurking. He's just being prepared.

Nope dont think it was me, if it was i was not sober.
I gave up on gas mileage along time ago.

Also I am fairly sure the tires are to wide for the rim. They look better and wear better. Plus like ben said, but he forgot mud holes too..
