new tires a week later vibration?

Hey guys. bought new duratracs last week were riding really realy nice. yesterday i noticed a slight vibe at 60mph or so didnt think much of it.. Tonight at 60-80 mps i cant hold the wheel... its only in the wheel not the floor. i had an alignment done in the spring. i checked all lugs madecsure theyre tight. checked pressures ok. checked for missing wheel weights cant see any missing but its possible i guess.. truck tracks straight even when vibrating.. If its not wheel weights missing what else could it be?! Thx guys

 

Sounds like you need to get your wheels balanced again.

 

How would they go out of whack that fast?

 

Hopefully this might help.

coulda thrown a wheel weight

 

+1, are they stick on weights or the old style? If stick ons you probably would not know by just looking.

 

Ya they are stick on...

 

Check you lugs.

Just happens sometimes.

 

If I'm not mistaken, the hub bore on the DC's are 110mm vs. the Tacoma 106mm hub. Get some hub-centric rings and that may very well cure your problem.

Did you go play in the mud with them? Wash the dried mud outa the inside of the wheels if you did.

 

Nope no mud... and ive had these rims on the truck since i got it no issues... just with these tires..

 

Then I'd return to where you had the tires installed / ballanced, and explain the issue and have them correct it. It might be a ballance problem, or a tire separation issue, so I'd get there ASAP.
