Tundra or Tacoma re gear with fourwheel camper opinions 4.88

[rruff]

Bull**** ********. I have compared a stock tundra to mine. And the weight is noticeable. Stock on 1st gen is 29 inch. Jumping to 33-35 can increase tire weight to 15-30lbs or more per tire.

What you are noticing is higher gearing and greater rolling resistance of tires with stiffer casings and tread. Those things can make a big difference, especially off the line. Not weight. This is just physics. The weight difference is tiny compared to the whole truck.

Guess Rotational weight doesn't matter than.

The only thing that changed was tire size as both tires was BFG KOs.

The truck is ~35% heavier too.

Based on what I was able to look up regarding overall gearing, my 6spd has a ~30% lower 1st gear and a 9% taller high gear (vs the 1st gen 4spd auto). The 5.7 has a much higher max HP spec, but I'd guess the 4.7 has relatively good torque numbers.

You also have 200hp+ more, double the torque and 4.30 gears stock.

Completely False. Dont pretend it’s physics that proves your point since it’s physics that proves you’re wrong.

Tire weight is actually near to zero in relevancy. When accelerating at low speeds it might be a 1% effect or so, and that's the worst it gets.

Stop.
Just.
Stop.

I know it's different. The post I was replying to stated that a computer controlled transmission would hunt for gears when a load was added. Does the 2002 even have a computer controlled transmission?

Some people like to obsess about things. Many who put 35s on a new Tundra feel the need to regear as well. That's without a load. They notice a loss in initial acceleration and it bugs them and they have to "fix" it. Others run 37s and load it with a big camper and it's fine.

For the $3-4k cost of a regear, I can think of other things I'd rather have. That's getting close to the price of a supercharger, which would be an actual power increase and not just a gear change.

Regear is $2200 - minus core - from ECGS

At the tread it counts for 2x, but it's still a tiny fraction of the vehicle's total weight.

Doing it yourself?

EDIT: Looks like $2.2k might cover it installed. Install costs appear to be all over the place, but the $3-4k I mentioned is on the high end.

One of us knows physics, and it appears that the other doesn't.

Huh? Please explain how spinning a heavier member isn't going to affect acceleration? Especially when you factor in that its diameter (moment) increased.... There is a reason race cars obsess over wheel/tire weight and don't just go with the widest tires they can fit

 

[rruff]

Like I said earlier, weight at the tread is 2x weight on the truck when determining mass-resistance to acceleration. So adding 10lb per tire will be like 80lb in the cab. On a 6000lb vehicle that's 1.3%. I think that's far below the threshold of anyone to feel.

Race cars will obsess about anything that costs them a fraction of a second. Another thing that wheel-tire weight effects is suspension (unsprung weight), where it's highly desirable to have a lower number.

That is painfully obvious.

Look. Let’s just all agree that you’re the smartest person in the thread. Does that make you feel better?

Now that we have established that, can you please excuse yourself so others can have a serious discussion and help address the OP’s questions?

Thanks

Ok guys so 4.88 or 4.56 ?:bike_rider:

4.88. Because you mentioned camper and potentially towing at the same time. Plus... if you feel it's over geared, you can still setup up in tire size eventually.

I think you'll love 4.88....

4.88. Go big.
