Tried a quick search- no luck: Does weight of wheels really make much of a difference?

Consider this. Generally speaking, the rule of thumb is, for every 100 pounds, you knock off 1/10 of a second. At least.......I think that's right. My memory taint what it used to be. I tell you who can verify it...... @70aarcuda Hay Tony, is my formula about right?

All good info, and nothing surprising. Someone was talking about how Alum/Alloy wheels just 'felt' better while driving, not to mention being lighter, so I wondered if that was true. I guess most of us just put new wheels on and dont weigh them first. Just a little digging on the net shows that a 15x8" steel w/weight around 30+(without centers and trim rings- probably another 2.5lbs?) and the same in Alum/Alloy around 20- thats close to 50 lbs!
