Lc250 KO3 original 18’ wheel - over 100km/h vibration on steering wheel

[exia001]

Hello everyone,

I’m new here. My lc250 has the KO3 with original size of 18’’ wheels. I have them around 42psi (cold).

And i always notice there is a vibration once I approach the 100km/h, and feel more around 120km/h.

I went to dealer yesterday and they did again the balance and rotated the tires. But this remains. And dealer said they do not have the specifications of alignment yet, probably receive in January. So they cannot verify the alignment.

I’d like to share this here with you guys, as any has any experience on it or any advice ?

Thank you!

From what you are describing, it sounds like a tire balance issue. BFG KO2s used to be somewhat notorious for being difficult to balance. KO3s have definitely gotten better as it relates to this matter, however, they too can occasionally be difficult to balance. You might want to have the dealer “road force balance” the tire or take it to a tire shop that has the appropriate equipment and the expertise to use it correctly.

The following is a link that describes the road force balancing process (it happens to be from Discount Tire, but I’m not necessarily recommending their services, it just happened to come up first):

Perhaps others reading this thread have some alternative suggestions.

Good luck!

Those tires don't balance out real good at the higher RPMS.
If the people doing the balancing know what they are doing you can rotate the tire on the rim and weight as necessary. Above a certain point reject the tire.
Stock or aftermarket rims will make a difference as well.
