Thread: New steering vibration coincident with new wheel rims

Hmm, there seems to be a glaring omission on this forum. Surely next to the "Thanks" button at the bottom of your post, there ought to be a button I can use for just such an occasion that says "Get ****ed".

Something worth checking if the tyres have tubes in them:
A problem which took me a fair while to find after repeated rebalancing, etc. Due to teat on tube too big for hole in rim.

Bought a set of near new 2.35/85x16 BFG MT on tubeless Wolf type rims. Aftermarket ones - looks like made by same manufacturer but no Land Rover part numbers on them. Anyway, got sick of slow leak in one so got tyre place to put a tube in it. Was balanced on dynamic balancer two or three times, along with other wheels. However, these only run at what is effectively a fairly low road speed.

Eventually figured out what vibration which only started above about 85 kph was caused by. There are different sized holed in the rim for the teat. The ones in these rims were the smaller standard ones, I think half inch, whereas the teat on the tube put in was fatter - the correct one for the approx 5/8 inch holes in Wolf rims for tubed tyres.

This fat teat went through the small hole but did not protrude out from it much. Seems what was happening that at low speeds, the tube stretched enough to contact the rim fairly close to the hole but at higher speeds, centrifugal force possibly combined with some air trapped between the tube and tyre caused this area of tube to move outwards. It was effectively like moving a wheel weight outwards or adding one in the same place at high speed to a wheel that was balanced at low speed.

Anyway, removing the tyre and tube, boring the teat hole in the rim to the larger size and replacing them cured this frustrating problem.
