Why dont all off road buggy wheels hex sizes are standardized

[vrooom]

like they do on TC cars, they all are 12mm hex.. off road buggy doesnt.. why is that?

[metalmickey0]

They almost do as far as i know. All my buggies and cars and trucks are all 12mm hexes. I know Durango`s are 14mm but just get a set of traxxas Emaxx hexes and job is done. Think its only associated that are odd but then thats the americans for ya. But you can get 12mm hexes for them too now.

Because they are all businesses

[knighthawk]

Because they want you to only buy their rims to fit your car

Trouble is most of them are all different off sets on the wheels so if you do get another manufacture wheel to fit the chances are it will make it handle weird.

Because the wheels are designed to fit the chassis rather than other way round...

some cars use long wishbones, some short,they all have different hubs and base geometry,

On some cars the design wouldn't work if there had to be room for a hex adapter... mainly 2WD fronts so the axles/hubs can be designed to be as far out as possible, plus unsprung weight could be an issue.

they run different offsets as part of design so just bolting on any old wheels because they have a similar hex fitting is not advised as it could cause handling problems.

A lot of it also comes from American cars running imperial hardware.

You have to buy wheels as consumables either way so its not really a major issue, a headache when swapping brands but they have a used value.

It appears to work well enough in 1/8 offroad and TC. It would make it all so much easier(for me anyway) lol

TC started in the 90s. Tamiya basically defined the class with the TA-01 (a shrunken buggy), virtually all the other manufacturers copied the wheel dimensions, those that didn't soon changed to the 12mm hex, and the standard was set.

Off-road is different. The major manufacturers have been in it since the 70s/80s. There was very rapid development of the cars which meant that each manufacturer was pursuing various wheel mounting systems and various offsets to get the performance they wanted. The class matured with car-specific wheels being the norm. So as time progressed you had Associated with the pin drive rear and imperial bearings in the front wheels, Losi with a different offset on the rear wheel and a small hex on the front wheel (which AE later matched), Tamiya with a 12mm hex, Kyosho with a 12mm hex but a different offset, and plenty of other bizarre wheel fittings (remember the screw-through wheels on Schumachers and the two- or three-screw fixing on Yokomos?)

A little while ago almost every car had settled on the Losi-style wheel fittings (pin drive rear, small hex up front for 4wd, bearings in wheel for 2wd). A few cars have moved towards larger hexes since then, which is both good and bad - the hex is a better design solution, but it means that the wheels are becoming car specific again.

Can remember having the Yokomo buggy after YZ10... MX4? can't remember name... awful car!

It had 6 countersunk screws to hold each wheel onto huge aluminium hubs... a team modification was to leave 3 out

I couldnt see it becoming standardised with buggies now... like Sosidge says its been the same for years and manufacturers each do well considering how many sets we all seem to lug about.

Sime... i heard your wheels get flatspots from sitting on the bench too much looking shiny
