pls explain this to me? brake failure stuff

[Jon|3.7]

"When changing tire sizes, we recommend staying within 3% of the diameter/height of the original tire. Any more than this and you face the risk of brake failure."

(im a noob to tires and rims and what not)


help:hail:


I'm on stock 18's 235/50 v6, going to 275/35/20 20x10 squared



(sounds like nonsense to me though) but I'm a paranoid person

You're fine with that setup.

Your good. I threw in 255/35/20 since you asked me about it in my thread

http://powerdog.com/tiresize.cgi

Tire size - sidewall - radius - diameter - circumference - revolutions - speedometer

235/50-18 - 4.6" - 13.6 - 27.3" - 85.6" - 740/mi - 60MPH
275/35-20 - 3.8" - 13.8 - 27.6" - 86.6" - 731/mi - 59MPH
255/35-20 - 3.5" - 13.5 - 27.0" - 84.9" - 746/mi - 60MPH

It's probably more a concern for cars with much weaker brakes than what we have. I don't know squat about it, but intuitively, larger rims/larger tire diameter could have a higher rotating mass, which would be harder for weak brakes to stop.

The statement is do to a higher rotating mass that a stock brake system may not be able to slow the vehicle as intended. Wont be an issue for your setup.

brotha listen to me you wont have brake failure because of exceeding a 3" variatio on the setup we are doing,

now if you went to 24s and heavy 24s then yes your braking would def not be topnotch, but it wouldn't fail like how their saying it.
