It's more a physical thing of fitting in the wheelwell. I could have fit two-sizes up from stock for a 4% larger diameter, but the tire jumped to 3+ lbs heavier.

At lest on my lupo I can barely fit even 12% taller with only minimal rubbing on normal driving. I have plans to suggest totally new tire design to them, what I have in my mind. It will have 3 things which will make it ultimate eco tire . But I need to discuss with their techichians if those changes are possible to manufacture like they work on my tiny head... They will also be lighter but thats not one the three things...
