Is putting on larger tires and modern rims a sacrilege

['68OrangeSunshine]

My '68 C/10 Stepside was originally ordered with 17.5x5.25 rims. I think it was a fleet municipal order, and the odd size was to prevent loss of tires to worker's private vehicles.
The OEM tires were 7.00x17.5 6 ply bias. That size went obsolete in the Mid-'70s, so I went to 8.00x17.5. In the Eighties, I upgraded to Radials, 8RX17.5LT. By 2000 AD, my OEM rims were shot after more than 300,000 miles. The 17.5 rim size was also obsolete. [It was always more expensive to get half inch bigger tires any way.]
I had to go with 16x6 white spoke rims and 235/85/R16 tires to get about the same stance.
Personnaly I hate the bling-look of excessively tall rims with rubber bands for tires. [Must be a terrible ride, too.] But I'm an Old Dog and hate new tricks.
