Depending on where you live, underrated titles like this would void your insurance in the event of an accident.

You can run the OEM XL tires at light load setting for a comfy ride. No problems. I see this as a solution to a a non-existent problem.

Your odometer will tick up higher than your actual miles. A minimal difference.

Tiny weak sidewalls.

Looks like.. redacted..

I see zero upside. All horrendous downside.

I’ve seen a few others do something similar. Usually a result of a sizing miscalculation, but not always.

An under-rated tire for the vehicle is an absolute dealbreaker even if there were any upside.

I think this is the mod equivalent of farting in your own space suit. .

I've been off car forums for a year or so, and your response makes me very glad I came back

Cheers mate

Glad my unsolicited, il-informed, non-constructive, idiotic musings could brighten your day.

Edit
Why you delete your post? Seemed very well thought out.
