Default lighter wheels=ET reduction?

Well I found out that my factory chrome 20" SS wheels weigh over 80 lbs a piece with tires. My question is how many tenths could I knock off with a wheel and tire combo that is about 20-25 lbs less a piece? I was thinking that I could knock off about .2-.3, what do you guys think?

If you went with factory silverado rims and tires oyu would drop 3 tenths thats what the vho guys drop over the 20's.

I remember hearing people say that every 100lbs. was a tenth (I never payed much attention since I was not willing to start "stripping" my T/A for faster times).

He could still benefit from from the factory rims though.

Its not just the weight of the wheels that slow you down. The rotating mass is what makes the big difference. For every lb more at that the wheel and tire is more like for lbs. The further the weight is from the center of the wheel the harder it is to accelerate it. It also takes more energy to slow it down.

as an example of tire weights slowing you down, i replaced my old worn tires that weighed about 34 pounds each with tires that weighed 40 pounds each and slowed down .2 in the quarter...

I am looking to stay with 20" wheels, I know Centerline makes a lightweight line of 20" wheels which is what I am looking at. The wheel and tire combo of these wheels is around like 65lbs which would be quite a bit of difference from mine which are like 83lbs. I don't know if Centerline is full of **** about how light there wheels are or not.

Look at american racing or centerlinesl ike you said they are forged and will be lighter. The centerline wheels are light my buddy had a set of 20" lancers on his truck and they were as light as my factory stuff IMO. Just get a forged set of wheels they will be lighter then get a low profile tire to keep more weight towards the center so they will be easier to spin.
