Glenn, in 46 years of driving, I've never had a blowout...a few flats,
usually discovered in the driveway or garage the next morning, but
I can count them on one hand. But, do what makes you feel comfortable.

The whole RF deal is mkting bs for Buffy to feel "safer", imo.
And, when you waddle down into "civilisation" on a RF one will have
to sit for a day or three waiting for that 275/40R20 RF tire to show up.
