Lunar Rock Club

Got word today it's due for delivery by 9/3 at the latest.

 

Looks so much better with bigger tires. But I'm going to stick with the stock size I'm afraid I tow my toys long distances and don't want to destroy the gas mileage worse than it already is lol

 

Congrats man. It’s going to seem like an eternity.

 

Understandable. From what I’ve seen, the larger tires maybe shave 1mpg. From what I drove yesterday, I don’t see a difference. Maybe a 1/2 mpg. Time will tell for sure.

 

Have to keep in mind your speedometer is off so the mileage is not being calculated correctly at this point so it's really difficult to say unless the speedometer is recalibrated

 

If you pay attention to the tire weight it ain't so bad, I went with skinny 35s to keep the tires around 65# each, I never drove with stock tires so I can't tell you how much mpg I lost, but before regearing and headers I'm usually in 14 to 15mpg during daily driving, now I'm around 16 to 17mpg.

On a side note, anyone had their tailgate strut failed? Mine just quit working this weekend, mounts didn't break, the strut just seemed to leaked out.

 

Ok so I was curious how much the larger tire size affects the calculation on MPG so I put together a quick calculation on it. Just for some rough numbers, not exact by any means. I have the math but wont bore everyone with it, so highlights below.

Assumptions:
- Without recalibrating the speedometer
- Assuming that tiresize.com is correct for MPH correction & revs/mile
- Averaged 20, 30, 40, 50, 60, 70, 80 & 90 mph correction %
- Calculated %diff for revs/mile
- Averaged adjusted speed %diff & revs/mile %diff = ~6.833%
- Not accounting for a decrease in diameter from tire wear

Going from 275/65R18 to 295/70R18. There is a ~6.833% difference in circumference which would directly affect shown miles traveled.

Over 100,000 miles shown, you would have actually traveled 106,833.4 miles. This is assumed you replaced the tires @ mile 1.

Driving this to a mpg figure, showing 14.9 mpg would be the same as 16mpg actual. This is due to the larger tire circumference and less revolutions per mile. Less revolutions per mile, equates to less miles traveled (shown on odo) per tank which would calculate to a lower mpg.

For anyone going to 295's, and who didn't re-cal your speedo, you can find your estimated corrected mpg by using: ("shown miles traveled"x1.06833) / 38 = "adjusted MPG"

 

Good call! I'm not that much if a math fan so I used the numbers on the comparison tool from tiresize.com . They will give you a difference of revolutions per mile (also provide you a chart for mph conversion) Stock tire number (629 rev/mile) divided by my new tire size (597 rev/mile) gave me the conversion factor of 1.053 for the actual distance traveled for every mile the odo actually says. So heres where my conventional math hatred gets me in trouble. I think I should just be able to multiply that 1.053 by the mpg my truck says and get an accurate mpg on the new tires. (Assuming the comp is accurate and something something distributive property and cancelling units) BTW I'm running 305/70 17 and I always lost points in math classes for not showing my work.

 

Best looking Lunar Rock I’ve seen yet!

Awesome job

 

where’d you get those flares? I like those

 

He said he got them used from a white tundra and had them painted. They are the Bushwacker OE Style fender flares

I just ordered a 4 pc set of them from Real Truck. They have the lowest price I could find with FREE Shipping and a Free 30 day Return Policy.

$319.99 + your State Tax

I haven’t been able to find a low price to paint like he did, best price I’ve found so far in my area is around $400. Still a pretty good deal

 

She finally came in. Picked her up yesterday for MSRP at Mark Miller in Salt Lake.

 

Congrats!

 

Love that new lunar rock smell



no pun intended…

 

Fuck yes

 

Found some dirt on the way home. I’ve owned it less than 24 hours and got some air already lol.

 

Awesome - congrats!

 

Hey cochese. Been trying to find payload info on a Tundra TRD Pro DC. Do you know what your sticker says for payload capacity?

love the truck btw, waiting for mine to come in

 

Arrived a few days early! Trying to change my flight to tomorrow AM.

 

Can't find the sticker (I don't think I even got it) but does this give you the number you're looking for?

 

Wow thanks for digging that up and taking the time to get a picture. Those are max ratings I think. Vehicle specific weight limits are on a sticker on the door jamb. Says something like “occupants and cargo should never exceed XXXX kg/lbs” and they stamp a number specific to your vehicle

 

I've got 1320 on my door jam sticker on my 21 DC pro

 

Same here, 1320 lbs on the sticker.

 

Thank you! Do you have any factory installed options (that were on your window sticker)? Bed liner, running boards?

 

I've got a sticker on there that says my capacity is reduced by 114lbs, but doesn't say what. I do have the factory installed bedliner with the coveted Tundra stamp and an aftermarket Leer tonneau

 

Only factory installed option was the black TUNDRA tailgate insert. I don't see any stickers mentioning reduced capacity.

 

I believe all pros come with the reduced capacity sticker regardless of body style. It has to do with the softer suspension setup we have

 

Rebooked my flight to today and flew out at 7 am and drove it back home.

No dealer games, no markup and all options on there.

 

Finally finished the stretch on my rock crawler. Tow pig was back on duty last weekend!
