If the diameter of a monster truck tire is 3.5 m and it makes one rotation every 5 seconds, how far does the tire

roll in 1 minute?

Diameter 3.5

radius: 3.5/2 = 1.75

12(2pi x 1.75)

=131.9 m

the book states that its 263.89 m?

What did I do wrong?

Looks good to me. Book must be in error.

the book is wrong you're right they didn't find the radius they used the diameter as their radius that is why your answer seem to differ from theirs but you're actually right.
