Tire Pressure in Aftermarket Tires

eagle mark said:
Yes and it takes a little longer so you can drive 1/4 mile and see good results. Should wear even. If it wears center to much air, outside to little but that is usually not the issue.

All depends on wheel size as well. 12.5 wide tires on 10 inch rims is easier then 8 inch rims.

The vehicle has been parked since 2007 and your going to get it and drive it home? :haha:

Unless I missed the part of working on it to make it run, you got a lot of work to do? Like five year old gas is your biggest issue... battery, mice nests made out of your wiring etc... who knows?

It's been started about every month. I was planning on putting some heet in the tank or seafoam
 
35x14.5, are thornbirds boggers? no info plate etc

My wife just went to her dads where the truck is and so I had her read me the tires. I was way off on the size somehow. and maybe the thornbird part.
They said they were TSL Bogger Super Swamper, and they were 35x14.5. 15lt

The maxload was 30psi @ 2726 lbs

Any intelligent comments on these tires, the size etc are appreciated

She said there wasnt an info plate on the door jamb. Does anyone have a 75 k5 that could look and tell me the weight, etc?

thanks for all the input and sorrry I was off so bad on the size
 
Your stock 75 from the factory weighed 4313 lbs. your tires are good tires. As long as they are not dry rotter I would run them. If max pressure is 30 lbs, with my formula you should be running at around 12 pounds per tire. Seems low but if that is what the tires are rated for that's how they will run best on road. If it were me I'd run them at 15-20 pounds and see how they ride. And watch the wear on them. The boggers were a harder mud tire I do believe.they will be quite loud onroad but look cool. They are tough tires and will last awhile.

thanks; service parts identification label

thanks for the numbers. Saved me some work. I just found in my chiltons the service parts identification label for my truck is in the glove compartment door.

anyway good info. After I read all the bad stuff about thornbirds I was surprised I got them as I always research even small purchases. I guess I had researched it after all and I just remembered the name thornbirds from my research. still dont know where I got the 40+ inch size though

I will lower them to 20 for the drive home (100 miles). I may try to do the paint test before.
 
Everything I read on them said they had a harder compound to dig into mud without deflection. Came up on three different sites I looked at. These tires are the older ones in think He said. Maybe the newer ones have a softer compound.most people said the sidewalls were hard and tough until broken in a couple thousand miles as well.
Here is a review from offroaders.com:

Interco Tire Corporation attempts to give this tire some street friendly attitude with minor success by breaking up the lug pattern to avoid a harmonic vibration but regardless the ride is quite rough, uneven and loud on paved road. Needless to say this tire is not one you want to commute to work every day with as it produces plenty of street noise and does not handle very well on pavement. However is is street legal, D.O.T. approved and actually does wear quite well, probably due to its harder compound.

Glad you are ready to roll in it. Hope it makes it home. 20 should do fine for that trip.

At this rate I don't think you're going to have it ready by the time your son is 16. :whistle:

LOL... :haha:


The good news is that the Thornbirds will be long gone by then...


I used to run a 38" Swamper TSL (15" wide) and the street pressure was something like 17psi. With a big, wide tire you need a lot less pressure than you'd normally expect.

He figured out they were Boggers, not Thornbirds.

I can't post pics now they were stolen. I posted a couple weeks ago about my planned build and explained it. I will post some though when I find them. Don't have very many since it sat for so long. I will probably get a different size this time. I think the stolen ones were 14.5. That's an odd size isn't it and probably why I got them as cheap as I did?

I can't get 16 that will fit or something more common? I know very little about tires in case it isn't obvious

I am sure the 14.50 was the width, not the rim size.

I'm clueless I guess. 14.5 is the width of the center of the rim? So that means when I get new rims they have to be 14.5?
 
No.

Rim width can vary widely. I have never seen a 14.5" (rim diameter) truck tire.
