the mud grapplers 385/70R16D2 is specifically what I was looking at

 

BAM!

90.39lbs per 37x13.50R17 Nitto Mud Grappler

Ha, now I refresh the page and see you answered. Stand by, I'll see what I can dig up.

 

not sure of this guys sources, but he lists them at 90lbs.

looks the same as the post here

awesome, thanks a ton for the info!

 

the google is strong in me

 

Two of the biggest advantages of larger tires:

Larger Footprint = better traction.

Larger Circumference = more verticle leverage.

Imagine that 90º angle is a rock. Lets say a 32" tire could cross that "stairstep."

===============

It would take a much bigger tire to bridge the gab and climb up this bump using the same amount of energy. Hold a dime up to the angles compared to a 50 cent piece if you don't see it.....

 

My tires need to be changed, so I have been looking for the pro and cons of going bigger myself...

Larger tires = Larger footprint = better traction, however you get less "actual" torque, and in an offroading situation, I would rather get more torque...

 

Yes larger tires without a change in gearing will put a dent in the torque, and thus put more load on the engine and drivetrain and kill the performance

 

In response to the OP and others concerned with the stress put on various parts by larger and/or heavier tires - you can calculate the centripetal force and centripetal acceleration via this link: http://hyperphysics.phy-astr.gsu.edu/hbase/cf.html
