Builds Project 200 (3 Viewers)

Not really, they are based on the 200. The only chassis differences in which the Tundra beats out the LC, are the front brakes, and the rear diff/axle/driveshaft.

How much does your wheel and skinny tire combo weigh? Any problems with unsprung weight?

 

[Overlake]

200 series chassis is shortened obviously over the tundra but markedly stiffer.

Let's make this clear. The land cruiser is toyotas flagship and the 200 is the best made production vehicle on earth today IMHO. Tundra is downstream.

The 255/80R17 BFG MT weighs 12 lbs more than the stock Bridgestone. The 17" Forged wheel is likely to be lighter the stock 18", but I don't know how much. The BFG is E rated and quite a bit stiffer than stock.... my point being this combo can be felt, and the chassis does not enjoy it in stock form. They do work great off road.

Overlake, you are preaching to the choir. I only meant that the Tundra brakes are rear differential are larger and more durable.

The 17x8 RW wheel is 22 bare and probably under 23 once you add the sensor and balancing weights. The rings are 2lbs each. The stock 18" wheels are about 29. I elected to go with the 285/70 17 Toyo AT2 but P rated at 48 lbs per corner. This means that I am only about 1 lb heavier than stock since I left the rings in the box. I think that this combo will suit me as a third set of wheels (Blizzacks, stock A/S and these for 'excursions'). I may even run them as my default set. All this ignores that the center of mass with a lighter wheel and a heavier tire has moved outward from the spindle. The wrong direction but nearly unavoidable.

I have now accumulated more empirical evidence. The P-series (Toyo A/T 2) running two pounds more than the industry load tables suggest ride softer that the stock Michelin A/S at the factory spec 33 psi. Likely due to 70 series in the main. In fact the harmonics and noises in the cabin are difference and for the better. Chalk testing confirms that 30 psi is a touch higher than what might be ideal for the P285/70 17. Every measurement down to an oz says the combo sans rings is within one pound of stock. Rolling radius is more obviously and the net effect is about like selecting 2nd gear start. Noise up perceptively but not obnoxiously.

I tow a trailer and a race car to tracks. In those instances perhaps an E-rated tire is superior. I suspect so, but for my use with a 3800 lb trailer/car combo this works just fine.
All of my data is by actual measurement and use. I was going to go with E-rated tires which Toyota suggests but allowed Elkaholic to sway my thinking and I think that works for me. More data will give me more insight. These tires on RW wheels ride 'better' than the stock setup. But this is not empirical--just my judgment.

That's highly debatable still (durability), but glad we're singing in the same choir.

Rear bumper time. Look at the surface rust hiding on the frame.

 

[MScruiser]

Gonna roll your own?

 

[bjowett]

Yes.

 

[MScruiser]

Oh boy. I am looking forward to this.

 

[elkaholic]

As am I!

A little design exercise/attempt at building a modern retro 18" steel wheel.

 

[Bomar]

Rim/lip stiffener over the wholes in Tundra steel wheel?

 

[bjowett]

Yes, exactly.

 

[arich]

I love how you continue to tease us just enough to keep us drooling.

 

[G-Cat]

Yes, exactly.

Hubcaps?

[Bomar]

I can't wait to see them on...
