Last night i was out and driving and doin about 80 and had to hit my brakes really hard well my car slid to a stop thank god. And now when i drive i feel like my whole car is bounceing like vibrating really bad and when i brake i feel something pullsating againt the brake pedel so i pulled the rear brake drums and turned the wheel and i felt soemthing pushihg against it that woul stop it so i loosed my brakes so the tire spun better and now im still gettin these vibratins and it makes me sick to drive it now any ideas...

 

You slid? Meaning you locked them up? Prolly flat spotted the tires.

my tires looked ok.. How do i fix that little problem if it is true but when i brake i feel like a thump on the brake pedel

 

i was only able to look at 1 tire and i did see a area that was worn down allot more do i rotate them all and powerbrake them or somethin

 

Oh and no offence but if anyone says get new tires im gonan kill them these tires ony have 10,000 miles on them and ive had them for about 8 months tops and they cost me about 500 for the set

 

Like it or not, you still might have put a flat spot on them - just cuz you can't see it, doesn't mean it's not there. You can have your tires "trued", which will bring them back into round again. I had a set of tires on my truck that did the same thing - no big deal. I wouldn't go making comments about killing people when they're making suggestions to you and trying to help you - that won't get you much help at all.

oh i wasent like i daid no offence i was just pissed.. Were would i get them turned at???

 

Yea, I know... Just giving you some **** back

Just call around before you waste your time driving around. I lived in Jax, Fl. when I had mine done. I doubt that all tire shops would have the machine to do it. It's kinda like turning the rotors on your brakes - same effect - smoothes them out again. I really don't know what the cost would be, either - it was so long ago when I did my tires. I would guess that just about any shop that sells the larger truck tires could do it for you. Good luck. I can't really think of anything else you might have done that would cause that, but going from 80-0 could certainly affect it, since you said you locked 'em up.

Heheheh, you want to see a seriously flat-spotted tire? Go to:

and admire what happens when I lock up my right front brake at 115 mph! Wore that sucker right down past the cords into the base rubber. Talk about a serious vibration! This was at the end of the long straight on the road course at Memphis Motorsports Park last year. As soon as I let off the brake and started making the first turn, I knew this wasn't a good thing...

ya my tires have bald spots on them so i guess its of to get a new pair i mean it slike it fgoes TRED BALD tred on the 2 fronts
rears i dono about

 

You might also check your rotors. With pedal knock-back symptoms you're talking about, you could've warped 'em. I know this is not what you're wantin' to hear, just something you might check out while you're spending all that money!

Well i got my new tires on BFG paid 152 for a set of 4 with alignment my friend hooke dme up at sears... but before they put the new ones on i went out behind the store and did a monster burnout down to the belts it was hudge and it riped aart the pavement and left wads of rubber... but muy car is happy now thanks for all your help

 

hey greg i see you have the gold colored rims, the color looks as rough as mine do. i managed to strip the paint and clear off, and sanded them with a assortment of sandpaper from 260 grit to 2000 grit then polished them with mothers wheel polish, they look almost like they are chromed. alot of work but i think its worth it. is your iroc white? with gold striping. by the way i flat spotted all fours this last sunday ride sucks now but it was fun, luckily i need new tires anyway.

Heheheh, that's brake dust, lots of it! Those wheels are an extra set I bought to have the road-race tires mounted on, and their finish is in better shape than my original wheels. All 8 wheels look much better w/out a nice layer of brake dust on them. You can see more pix of my IROC on my page at:

BTW, I prefer the gold color since it matches my black car with the single gold stripe.
