I'm thinking of changing my stock 360 wheels to hre 19" with Stradale rubber. My motivation is grip, road tire sidewalls too soft. My only worry is that the hre's will add about 2.5 lbs per corner. The wheel weight the formula is total wt (10lbs) x a multiple 0f 4-7, say 6, so it adds 60 lbs of inertia. Will this make a noticeable difference in 0-60, etc, or will the sticky rubber far outweigh the extra weight? I was told a one piece vs. the 3 piece hre's would be the way to go but I haven't found a single manufacturer that makes 19's in 8" & 10.5". Thanks for any help.
