2000 2wd 2500 crewcab bigger tires equals better mpg?

I'd put new cats on, hook your 02s back up and run a good quality muffler (since all that's gone,) and you should notice more difference than taller tires...

I still have cats and stock exhaust.. Thinking about doing some flow masters with an h pipe but that's a few months off..I'm still kind of in trouble for buying this truck in the first place

Cats wont help your gas mileage if its a stock cat it probably hurts it honestly get a nice free flowing exhaust and that should help

all 96 and newer 400s have a "high flow cat," so there is no use removing it other than killing your flowers faster. I guess I read your sig wrong, thougt said you have o2 delete and straight pipes.

Py0 is the rpo for the hd aluminum wheels. I believe great white stated that they were lighter then the factory steel wheels

I'll just quote my own post rather than type it all out:

Finally got around to weighing the steel wheels: 34 lbs! that's 136 for 4.

The PY0's scaled in at 17 Lbs. That's 68 lbs for 4.

That's a whooping 17 lbs per wheel and 68 lbs total difference!

Exactly half the weight.

No wonder the difference in the truck is so noticeable.....that's a huge weight drop in one of the most effective areas!

I've installed aluminums on vehicles before but never with this much of a difference. But to be fair, they were pretty much all aftermarket rims or older oem aluminums built before the rabid gov't pursuit of improved mpg.

Viva la tightening OEM MPG requirements!
