Bud:
At the risk of instigating another P vs ST tire controversy, I note that
my '81
Bigfoot has P225 75 R15
tires. While I find the numbers associated
with
tires somewhat of a mystery, I presume the R15 means 15" radials, so
I guess the answer to your question would be yes. I can't comment on whether
the 15" is better, since that is what I bought it with, but from my point
of view they seem fine. There is lots of clearance for these tires.
Speaking of Bigfoots (Bigfeet?) I notice a Bigfoot 5th wheel I pass daily on
my ride from work is
for sale. This might be of interest to someone in the
Calgary, Alberta area. There is no phone number, just the sign, and I have no
details on size or year.
