substitute P235's
 

Hi all,

I am in the market for new tires (ON A BUDGET). . A co worker has a nice set of Bridgestone 265/70R15 tires. . . . My Blazer came stock with 235/75R15 tires.

1. Can I use the 265's?
2. I believe the 265's are bigger, will this affect my speed odometer
3. what about my fuel economy?
