Usually IMHO is an abbreviation for "in my humble opinion."
You might also see YRMV - "your results may vary."
In regards to your earlier question about sliding the tire - yes, you could be at the limit of your tires, but there could be some other factors to check like tire pressure, are you getting the tires sufficiently warmed up, are you loose on the bars, etc.
Thanks for the Info. Sorry didn't understand the abbreviation. Older Generation here. Tires were warmed up. Maybe a little tight on the bar. Was trying to be loose and Comfortable.
Thanks again
