Fast question.
What is the handeling difference between a 90/90-21 and a 80/100-21?

The tire sizing works like this 90 tire width / 90 tire hight -rim size.

Yeah I understand how the sizing works was just wondering about differences in performance.
80 = width
100 = percentage of width to height so 100% = 80 height
90 = width
90 = 90% of width = 81 height
So only difference is from my understanding 10mm wider on the front.

Currently I'm running a 90/90-21 and thinking about going to a 80/100-21.
