19" vs 21" wheels & tires

[mc0819]

honestly, the range delta is not that much....
when I had my 19's on 245s I averaged 370wh/m
with aftermarket 21's on 255's and 285's, I average 380 wh/m

Hi my p100d wheel spin a lot on the 245/45/19 Michelin ps5 tires, will change to wider 21 inch 285 tire get rid of this problem? Please get back let me know

That's a much wider wheel, so more than likely. However, you could also get softer 19" tires. Why not do a 255/45/19 kumho ps91 or continental sport compact 6? Both of those are roughly 30% softer than the PS5.
