Tire balance affect brake pulsations?
KG
radials, the Lexus experienced servere brake pulsations upon application at 60+ mph, would brake
fine 50 mph and below. Using the 5 tire rotation pattern I determined that the only right front
tire was changed, being the left front came front the right front. I placed the spare on the
right front and almost eliminated the pulsations. Returned tire and car to tire dealer who stated
he had never heard of such a problem caused by tires, we placed the defective tire on the right
front and the dealer drove the car and agreed it appeared to be a tire problem. The tire dealer
did a fine re balance of all the tires, they had all changed by small amounts he stated, and with
the apparent defect tire again on the right front the problem was totally eliminated. I never
would had though slight tire balance could affect brake performance.

Probably not a balance problem. More likely there was a laterally out of true tire.
Happens all the time with all brands.
Anyone that works with tires knows that.

What does brake pulsation mean?
Obviously it must mean you apply the brakes and something happens. Does
the front end shake? Does the steering wheel shake. Or is it the brake
pedal where the pulsing is felt? Or is it some combination of the 3.

He didnt change the tire, nor did he say they did anything to true it. That
caught my
eye immediately.
I dont think it was the balance either. Maybe some dirt or rust that wasnt
seen when the wheel was bolted up? If they rechecked the balance off the
car, it might have been bolted on true when they replaced it.

They did nothing to the tires except re balance them. I was present all the time. The symptoms
were exactly like warped rotors, pulsating steering wheel movement & noise. The 5 tires were not
much out of balance but the worse by far was the original right front tire. All the tire weights
were marked as to position & size before re balancing. The original rotors are still on the car
and I recently 6-8 months ago had them lightly faced ground on our face grinder in our machine
shop, they were within .0005 ". Below 45- 50 mph braking was normal with very little shake which
is normal due to road etch. I never would have thunk.

Tire balance will not cause brake pulsations.
Improper lug nut torque will.

A nice little fairy story, it never happened.
