This truck can't handle 285/70/17

Hi all. I've got a 2005 sequoia with these tires mounted on 4Runner TRD PRO wheels and spidertrax 1.25 spacers.

Not only is it getting 9.7-11MPG. My suspension is constantly wearing out. Tires are rubbing and it doesn't ever seem to align right.

Can one guide my novice experience? Im sitting on 5100's top notch up front and 5100 with OME 862 +deflated airbags on the rear. Also have SPC UCA.

 

Your rig has altered Toyota designed suspension. Different angles and wear plus super heavy tires to help west stuff out and take more energy to get rolling and stopping. Don’t like it I would suggest smaller tires and maybe a leveling kit instead of a 2.5” lift. “I’m assuming that’s what your sitting at.”

 

Also, you probably aren't getting that low of mileage because you probably aren't accounting for the true distance traveled on a tank versus the distance on the odometer. The actual distance traveled is probably more than 10% (my 275/70R17s travel 108 miles when the odo reads 100...verified by highway mile markers). So you have to add at least 10% to the miles traveled and then divide by gallons.

And you probably just need new wheels with the correct backspacing. Lot's of people run 285s with much issue (but may require trimming).

 

Thanks for the input.. I was previously running 275/70/17 without much issues at all. It seems like 285's have pushed it over the edge. Is the lift too high? I'm starting to get over putting money into this thing!

It's sitting on these wheels

Best tire sweet spot for the 1st Gens is 285/75/r16 of which I’ve been on for 17 years without lifts. Only been through one front rebuild last year.

Get rid of your lift. Switch to 16’s. Rebuild the front and get a proper alignment (new cams bolts) and she’ll love you long time. $$$$

I add 8% to my MPG calculations and its not much better than yours.

HWY 16-18

Ixnay the spacers.

 

Do you mean 265? He has 285’s right now

 

He is on 285/70/r17’s.

I’m suggesting 285/75/r16’s of which is the size I prefer and seems to be time tested.

OP has reengineered things that add too much stress and wants to stop rebuilding. I’m sure it looks cool, but the trade off is what the OP is suffering from... a stressed vehicle suspension.

 

They’re the same size tire. Switching to 16’s is an absolute waste of money!

 

Thanks for your input.

 

Just educating the less educated.

 

Gotcha, I am just thinking most the weight is coming from the bigger tire, I wonder what the weight difference is between a 285/75/16 and a 265/75/17

 

I’m running 285/70/17 on a 4Runner with no issues at all

 

Cool! I have a sequoia which I'm sure is different from a 4Runner.

 

Thank you Sansei.

What, Sansei, do you suggest? We await your wisdom Sensei!

Toyoboyo has a problem. Admits he wants help. Help!

 

I think ditching the wheel spacers would help. Might have to do a little chopping to make everything still fit.

 

Besides the big heavy wheels that sure makes it a lot of leverage on all his suspension components

 

Here is the OEM wheel that I was referring to pair up with the 285/75/r16. The tire I prefer is the Michelin Defender LTX and it rubs slightly on the inside frame if the steering wheel is cranked hard.

I believe the offset is +15.

Keep in mind I’ve read others try different brand/style tires in the same exact size. They sometimes report heavy rubbing when switching over to different style tires. While charts help, sometimes they aren’t exact. There are many variables even the experts can’t predict.

One thing is certain. Lifts, spacers, and too big tires will wear out a suspension. When all 3 are combined the wear compounds itself. Offset plays a big role as well.

 

Not an expert here, but I believe our 1st Gens can only run the 1.25” minimum spacer due to the lug posts.

 

Depends on the type and brand tires. Most tire companies have charts where you can check. Wheels add weight when the tire is reduced. Its a trade off. How much exactly depends.

 

I’m pretty sure I am correct that 1.25” is the minimum. OP has a Sequoia which is a Tundra with more seats. We are talking 1st Gen here.

 

Simple answer... don’t like replacing components and poor gas mileage drop tire and wheel size and lower angles on suspension components.

 

One last thing that a non-expert as myself notes in the OP’s first post: 5100’s set at top notch.

I know on the 2002 Tundra the top notch is a no-no. Second notch from stock height is the max Billys recommend going.

Could be the reason the alignment won’t hold?

 

Already noted prior to your mention. See post #25.

 

I could have used you a few times on this thread. Did I do ok?

 

What do you mean by “my suspension is constantly wearing out”? Where are the tires rubbing? Also, what brand tire? P or LT?

I’m not sure why your truck can’t be aligned since you have SPC uppers and they have quite a bit of adjustment in them. Lca bushings could be worn and can’t hold an alignment.

 

Same over on turd gen section. I comment and you guys are like a pack of hyenas. We appreciate your help. You just need focusing on the original post.

 

Different size components but they’re the exact same.

 

What year models are we discussing now Sensai? We had a 3rd Gen infiltration. Did you pick up on that?

 

No hostility bud. Just a comment. You took it wrong?

You just didn’t read the OP. Its ok. We all make mistakes.

 

Whoa.

I would like to see answers to Caspers questions, what is wearing out? Why the belief that it cannot be aligned? Did more than one shop try?

If we wanna get super technical PHM has a point on 16" wheels vs 17" wheels. The barrel of the rim being closer to the hub means less work to rotate, but the cost of swapping wheels and tires won't be realized in benefit.

My suspicion is that the OP doesn't drive in a fuel conservative style. I could get 5 mpg if I wanted to, but learning how to adjust driving habits allows me to get 16 mpg and greater.
