With a 2021 Amarok V6 the swap from large diameter OEM alloys with rubber bands for tyres to a more suitable higher profile Goodyear tyre on a steel wheel generated vibration. Difficult to isolate to the wheels, tyres, hubs, balance or wheel alignment. Had the wheel/tyre balanced (three times) 7gms off balance at one check. Eventually decided to use some proper engineering assessment criteria, and measure. The wheels were running out, in the vertical plane by about 1mm (0.039") measured with a dial indicator from my lathe - just visible movement in the tyre tread. Removed the wheel - checked for wheel damage (wheels are quite new) and inspected the tyres - no apparent issues. Cleaned the hub surfaces with a wire buff on the 'angry grinder'. Ran the dial indicator over the hub with the axle turning - running pretty true. Set the wheel back in place and noticed that the wheel had 'settled' on the hub - 0.9mm gap between hub and wheel centre. These wheels are supposed to be "Hub-centric" THEY ARE NOT. Refitted the wheel with a 0.035mm shim supporting the wheel against the top of the hub - feeler gauges meant we could actually centre the wheel with reference to the hub - now we know it's centred, carefully pulled up the wheel bolts, torquing those fasteners in stages and checking all around with a feeler gauge - wheel now centred accurately to the hub. Final 160 NM torque (using a torque wrench NOT a rattle gun) - did all 4 wheels and took the ute for a test flight ... at least 95% of the vibration gone. Now searching for proper 'Hub-centric' steel wheels. Oh yes, we have the new style wheels, and they DO NOT engage with the hub as you suggest.
I understand your comment, but don't you agree that 5 screws, made specially to center each on its centers in the wheel and hold, should be more reliable to center the whole thing?!
Not when you have a 40 - 50kg wheel & tyre combo and you are relying on a very thin taper (on a steel wheel) to try and lift the wheel into the right position. The Centre hub spigot is there for this very reason - to centre the wheel. This is less of an issue with an alloy wheel that has a deeper taper but it's still better to centre the wheel on the hub - Jarrard
It's possible. It could be the wheel is not centred correctly, or it could be a wheel balance problem. If it only happens at take off, and under ~20kph, then usually that is a driveline vibration and you might need to install some caster wedges on the rear leaf packs.
You may have a centre-bore location issue - but the first thing to check is wheel balance. Checkout our 2-Part Video on Wheel Balancing and Roadforce which explains in more detail. th-cam.com/video/tvjpsSrCWEQ/w-d-xo.html
Hi Peter, you are correct (perhaps you should watch our other video where we discuss fitting hub rings). The problems arise when people don't fasten the wheel studs in sequence, locking the wheel slightly off-centre. This is particularly apparent on the Amarok when fitting a heavy wheel and tyre assembly, since you are relying on the lug taper to pull the wheel into position. This can be helped by taking some of the weight of the wheel whilst fastening. Having a wheel which locates from the centre bore (like in this video), either being hub-centric or by using hub-rings, eliminates this issue all together and allows the lugs to locate the wheel without also having to lift the wheel into position. - Jarrard

Bf goodrich letters in yellow???
I have steel wheels and it shakes / vibrates on take off is that my problem you reckon

I have amarok 2.0 automatic transmission when i am driving 45 to 60 km hrs i fild vibration i can find the problem plz if some one can help me

Total BS! What centers the wheels are the screws/bolts!! Amazing this guy claims to be an expert!!!
