Those 18s probably weigh less than the stock 16s, but then tires weight is just as important (if not more) as wheel weight. You will find that as you decrease the size of the sidewalls the tire gets heavier and it will increase your rotating mass. So, no matter what, you will see a decrease in acceleration if you get 18s.Anarkraft said:I must know the weight of the 16s, I wanna buy some 18s, but is 18.5lbs per wheel without the tire, more or less than the 16s weigh?
The sidewalls are bearing the load on the tire. When you reduce the amount of sidewall, you aren't reducing the load. Therefore the sidewall needs to be stronger, and tire manufacturers add reinforcements to adjust. Those reinforcements end up making the tire heavier.Anarkraft said:wow, really? That's strange, I would have thought the opposite about the reduced sidewalls, but i was thinkin of getting them with some bridgestone potenza S-02's at 215/45-18 will that really weigh more?
