Considering you are going from an 18 inch to a 20 of course they are going to be heavier.
Stock 99/00 w/ tire was 62 lbs (18 inch)
Your 20s will be 83 lbs.
I run 01/02 20inch replicas and ran an 11.92 with them on the front and a 1.59 60 ft w/them (heavy a$$) 20s on the front.
So get the Harleys and do not worry and have fun.

The only possible negative would be faster wear on the bearings and faster wear on the brakes with the added rolling weight.

Looks like that it won't make to much difference for someone who just runs the truck on the street and doesn't drag it. I think the HD's look good on the trucks. Are the lugs size and spacing the same from the HD to the L's like 01-02 years? + are those 295's you talked about speed rated to what?

 

Rims/tires are unsprung weight. Adding 1 pound of unsprung weight is like adding a few lbs. of sprung weight to the vehicle. I don't know what the rule of thumb is, but lets say hypothetically for the sake of easy math:

1lb of unsprung weight = 2lbs of sprung weight.

So if you replace a rim/tire combo that ways 40lbs with one that weighs 80lbs you are adding 40lbs per wheel x 4.

So thats 160lbs of unsprung, which would equal 320lbs of sprung weight.

Hopefully someone else could explain it better and give a better estimate of what it is.

Is there a simple mod for a stock L that would compensate for lost acceleration or will it be to little to tell?

 

There is more weight. But I could never tell.

 

Tom,
Why would you want to cluter your nice truck up with those REALLY heavy and clunky Foose rims? Please let me know where you will put them, and I'll arrange to have them picked up.

who is Tom? I think the rims look AWESOME.

 

Captainoblivious thanks, the explanation and link helped…
lol, don’t hold your breath waiting for that one buddy…

if you're not going to drag race or do autoX, get what you want. 18 inch or 22 inch, as long as the tire isn't too tall you'll just be out money. the loss in acceleration you can make up with a simple bolt-on..or more since you have the $$$ to bling.
