How does putting a tire on a stock car increase its acceleration tremendously? School me. You might run a faster time with a tire due to getting traction right away or much earlier in the run. But how would a tire help someone in a roll race where acceleration is all there is? Or a 60-120 time. Or a 100-200 time. How would a bigger tire help that?
I assume, in theory, a taller tire would slightly increase acceleration due to a larger surface area making each rotation a longer distance gained. But noting substantial. However, in the real world, this doesn't happen. A smaller tire will increase acceleration. But I don't know hardly anyone, when installing a "tire," that puts on a smaller than stock tire...

Thanks guys glad you enjoyed it lol.
The first 5.0 spun pretty bad you can kinda hear it. The green one had an exhaust and a 305/45/18 nto5r he jumped out about 1 car maybe 1/2 a car and still got pulled by 2-3 cars

Still waiting for 2003Cobro to school me. After he made me feel like a dumbass last night when I posted that, I did some more extensive research about it. I'm getting mixed answers still, but most of them are saying that a bigger tire will make acceleration slower.

A tire will increase acceleration when it's lighter, smaller, or prevents loss of traction. In this case the 5.bro was spinning... If he had hooked he would have accelerated faster, and that's something tires can help with.

So if the stock 5.bro in the video has a 305/45/18, then that means he went a size down from 50/18 (in diameter). He went up in width: 305 compared to 235. In this situation, I can see where his tire choice would help him accelerate slightly faster than a factory tire 5.0. My first post was assuming that the tire he was on was not only wider, but taller as well. Didn't realize he actually went one step smaller.
However, a taller tire will not increase acceleration. Which was where my original statement started. I was thinking of taller tires when I made that comment. I should have specified more than I did the first time.

In most cases but depending on power curve a taller tire is going to decrease acceleration unless the shorter tire was spinning and the new taller tire now has traction. Taller tires take away from your effective gear ratio while going shorter increases it. The only new question I have about gear ratio's is no matter what size tire you put on, is there a difference in torque multiplication and gear ratio effectiveness when the ring and pinion is changed. Regardless if you changed tire size to keep the effective gear ratio the same. Kind of like changing a stall in a automatic.

edit: rewatched the video. Its a freaking dig race. If you dont see how having a stock POS 255 tire vs being on a sticky tire can help then there may be no helping you.

This is all you need to know. When you have a high hp car and try a low roll you roast the tires and spin. Spinning = not accelorating. Im sorry i drove you into a research frenzy. Even stock on shitty stock tires my buddies 14 5.0 would roast the tires on a low 1st roll. Now the modded one is on crappy tires the stock one is on a sticky tires. He can hook and immediately is accelerating and putting power down. Modded car is spinning all his EXTRA hp is going no where. Once he finally hooks he is now playing catch up. Make sense?
In my head, I was thinking of a totally different way. As in, if this was a perfect world and traction wasn't an issue ever, then how would putting on a tire help acceleration in that case? That's what I meant. That's why i stated how would it help a 60-120 run or a 100-200 run where traction problems are usually nonexistent unless you have a monster of a vehicle.
I didn't think you were gonna take it as literal as possible and use not having traction as not accelerating lol.
However, understood. Good pep talk.

Alrighty, so when I said, "how does a 'tire' increase acceleration?" you took it as literal as possible lol. I can't really explain it over text but the way you just answered me back wasn't what I meant in the first place. I understand that spinning means no acceleration, so therefore, in that situation, it does help you accelerate.
