    Rims cause break bads/discs to over heat?

    I've been told by 2 diff shops that when u put on rims that are alot bigger then stock it will cause ur brake pads and or ur discs to over heat and become warped or break pads become cracked. I've had both happen to me. There is a dude that works at the shop i go to he has a 01 rolla and he said when he got rims his pads and discs started to over heat
    Is there any truth to this.
    I got a 00 rolla

    It's possible if the rims weigh considerably more than stock, but also because the rims are bigger, there is more mass hanging further awa from the hub (hold a 20lb bag 6 inches from your check and then do it again with you arms fully extended, see how much harder it is when your arms are fully extended bcause they are further away, sort of the same idea, easy way to see for yourself) so that weight further out makes it harder for the brakes to do their jobs, hence making them work harder for the same braking and wearing them out/overheating them... if you drive agressively, buy smaller, lightweigh rims, problem will go away... big, heavy rims are only for show, not for aggressive driving...

    pepboy tuner rime don't weigh and much as you think. I had my 18's with stock discs before i had the brembos and they did pretty well. i had ceramic brake pads on both sets. my rims weighed 26lbs per each rim and tire combination. I NEVER had my discs warp on either set. the only thing i exprienced were smoking brake pads. you can tell they are overheating if they have a "rainbow effect" on the disc. if this happens you need to replace the brake pads and discs immeidately. My friend experienced this and he has an 01 rolla LE. Generally the same as mine but the LE model. if you go with something that is 30 lbs or heavier (combination weight) then you definately going to get these problems.

    they should be fine. ANYTIME they get an effect such as you describe they must be replaced immediately. this means they are overheating.Try not to brake very hard unless you need to.Replace your brake pads as well with new ones get ceramic if possible.They will last longer and brake better.

    26 pounds rim AND tire? Your rims mustve weighed 8 pound each, because tires weigh a minimum of 18 pounds.....

    And I dont see how larger rims and tires can cause break pads to overheat...I think the main problem with larger rims/tires is tightening them too tight, which will cause your rotors to warp pretty quickly

    larger rims/tires requre much more energy to stop due to the increased rotating mass and the said mass being moved away from the center of the wheel, hence the problem with overheating.

    I went by what was stated on the P.O. when i got them. and this what it says if its wroong then ok but its what it sates. the rims weighed a shitload and the tire was literally a rubberband since it was so thin so it did not weigh much at all.

    brake pads overheat when thet become crystallized. when you replace the disc and if you notice a shine and/or cracked pads then they have overheated. using semi-metallic,or organic usually crack. Ceramic or carbon metallic work best from what i have experienced.

    what it does is heat up the rotors and drums b/c it has a bigger radius to stop that is why most people get new rotors when they get rims

    it has more weight and are heavier generally when compared to stock alloys. also fi you read what Johos stated it has more rotating mass which is true.

    that will/may cause your problems especially at interstate speeds.60 mph and above can cause this overheating problem on ANY car what so ever.

    just as well.. huge rims look wack anyways.
    maybe you should get the ones that spins, I hear the fan air into the brakes making them cool fasta-r.

    maybe i should look into cross drilled rotors, if i find any. But i'm pretty sure i still got warranty on my brakes including my discs and my pads, so if they go bad then i might get new ones, i'm not sure yet, i have to check

    Warranty is usually thrown out if they suspect overheating of the components - they'll blame it on abuse. Unless you got in writing that they warranty will cover that type of damage.

    A different brake pad (Hawk, Porterfield, EBC, etc.) that can take the heat can make a huge amount of difference. Sometimes it is an issue of bedding the pads in well. As long as the offset is not too extreme (too far in or out) and the weight of the wheel, even though it may be heavier, is centered over the assembly like the OEM wheels - you should be OK. If it is too far off - you could put more stress on the bearings than what they were originally designed to handle and end up with bigger problems down the road.
