[RT SYD UP]

I "upgraded" to a 21 inch vorsteiner on my 2014 CP. It has 265/25/21 F & 295/25/21 R. The ride is good but they are incredibly easy to rash or nick from the slightest pavement imperfection. Could I step the sidewall height/percentage up. Any recommendations or is this the breaks of a 21.

Thanks
