Stopping

I'm assuming my brakes are going (I have 55K on them). However, I just upgraded my tires from 245/70/16 to 265/70/16 and I find it is harder to stop. This just started when I put the new tires on.

A.) is it because I have a bigger tire, and no need to upgrade the brakes?

B.) yes my brakes should be upgraded?

Thanks for any info!

probably a bit of both

the larger tyres create more inertia which makes it harder to stop, after 55,000 miles you will be needing new pads making it harder to stop

Old brakes really don't make it harder to stop. The slight increase in stopping power is a result from a larger diameter wheel and more rotational ineria from it being heavier. At 55K it is probably time for new brakes anyways.

Yeah like they said. Anytime you get taller tires you are putting more leverage on your brake system. It's the same principle as if you use a 6" ratchet and you can't get a nut loose...you go grab a 10" ratchet and it comes free. With the longer ratchet you get more leverage, therefore more power. With taller tires, the tread is farther away from the center of the hub...therefore there is more leverage working against your brake rotors. That's why it takes longer to stop. If you go too big you can actually create a situation where it's dangerous to drive the vehicle without upgrading the brakes.
