Look, I don't want to be rude to you, but sometimes we can't decide if you're trolling or seriously misinformed and some of your comments are so way off base at times it's crazy.

I asked you to explain how you came to determine your thoughts on the subject matter, and here you flip on me to prove you wrong? Seems a bit backwards to me.

But to simply answer your question, Jeff picked up power by simply decreasing the amount of rotating mass on his wheels allowing them to turn much easier. Reducing weight is just as good as making more power.

My forged 20's are lighter than your cast 18 inch wheels. The only argument you could possibly make is that a 20 inch wheel could change gearing if the same tire height was used, but it's not. By using a lower profile tire with my 20, the gearing is very near the same as it was with the stock 19 inch wheels/tires. So really, you are just incorrect and your argument is null and void.

Ford puts tiny tires on the car to get the gas mileage CAFE standards up. 235s on a 3600lb car with 400rwhp? Please. That shit is damned near negligent homicide. Tire grip should be the first thing you think about when building up your performance car, not gas mileage or 'soaking up' power. My wheels may be heavy-ish, but they're not as heavy as my stock Brembo wheels and Pirellis were. And when I need grip, I got it.

I agree with your statement and the negligent homicide part had me rolling. lol From a roll stock to stock the stock rim car will be faster then same car with 20's and wider tires. No?

I doubt it cause I broke those 235's loose going hwy speeds when I slammed it in 3rd.

If the entire wheel+tire setup for the 20s is heavier than the stock setup, then yes, stock wheels will be faster. If the 20s are lighter, the car with those wheels will likely be faster.

Rotating mass if a big deal. The less weight you have to rotate means the motor will rev faster since the work being supplied to turn it is less, giving the motor more power to push itself forward and accelerate.

QFT. 70 roll. LOL

They are designed to work with a skinny tire to provide the ability to lean as they turn/pivot. A wagon would be a better example to compare with a car. A larger tire gives you a larger area in which to spread the load. This means the object will handle better because the weight ir more distributed on the tire surface, making it handle more precisely. The only difference having a 235 on a wheel barrow would make would be the rolling resistance, but once it is rolling, you wouldn't be able to tell the 235 and 295 apart.

Lot more can go into that but yea pretty much.

Because 5.0 racecar.

You dont say?

No, you can't say that with any certainty.

I cant but its an educated guess. Theory.

How the fuck did we get to how stock rims are better then 20" rims from whats the difference in year models?

Same reason as every other thread derailment.

ADD.

So what tire size should i be running on my wheel barrow?

[Sieran]

This thread made me seriously reconsider how i pronounce the word wheelbarrow (i always thought it was wheelbarrel).

I've always known the real way, but saying "barrel" is more fun.
