If you mean you do not like the appearance of the small tire height-to-wheel diameter, your two choices will be to go to a taller tire (i.e., larger tread OD - which could be accomplished with several combinations of treat width/profile) which will throw off your speedometer/odometer readings but will change the tire-height-to-wheel diameter appearnce, or to go to a smaller wheel and higher profile number (maintaining similar tread width) to change the appearance and maintain the same tread OD and speedometer/odometer calibrations.
Or do you mean you want a narrower tread and higher profile number to maintain the same tread OD and speedo/odo calibrations but change the ride/handling (i.e., appearance from a tire height-to-wheel diameter standpoint will remain mostly unchanged from what you have now)?
