33" / 35" durability issues + tire weights

[MichiganAve]

With some of us planning on pushing unfamiliar territory with the 4.5" lift, I thought I'd open a discussion about durability issues with 33 to 35" tires. I know that Colopathy ran 33x12.5s and Matt ran 34x10.5. I don't know what Keith has. There are quite a few 2-3" lifted guys going with 33x10.5s now. I don't think anyone has seen consistent problems with this limited experience. Are the likely weak points the tie rods and the double universal joint steering extension?

 

It seems to me that the increased wear on components and reduced gas mileage/acceleration is a product of radius*weight. This is why I am aiming to save weight in the rolling mass. I have purchased ProComp alloy 8023s that weigh 26lb in 16x8. I also have done some research on tire weights:

I am pondering a BFG MT 305/70/16 which weighs 56lb, only 5lb more than the 265/75/16 BFG ATs in my living room. I couldn't find many weights for interco tires but they are rumored to be a very heavy brand, so I am no longer considering a Trxus MT, I will instead sipe another MT tire myself.

Wow, great info in this post.

 

My question is - can driving techniques effect the life of power steering? For example, not letting my girlfriend crank the wheels from left to right while at a standstill?

[94extreme]

yeah fueler. no turning of big tires unless you're rolling.

[max_stryker]

of course not turning when at standstill with big tires is a common issue even with....domestics.

[FUELER]

my girlfriend always does things that make my heart skip a beat.

 

For example, turning the wheel from full left to full right while at standstill,

 

 

or when parking on a hill, she puts the auto tranny in park (without the e-brake) and lets the QX4 rest its weight on the tranny. THEN, she pulls the ebrake last.

 

TERRIBLE!

[max_stryker]

ever think about NOT letting her drive

[vengeful]

ever think about NOT letting her drive

Well, I wasn't going to say it, but I'm glad you mentioned it Max...LOL

Never came back here and posted the weights I found out.

 

The stock size spare, 255/65/16 mounted (couldn't tell what kind of rim) weighed 67 pounds.

 

The 35x12.5x15 on a heavy steel rim (15x8) weighed 97 pounds.

 

Yes, 30 pounds is a big difference, but if you look at the size difference, I would have expected more.
