Anyone Darksided their cruiser?

[skippa1]

They tend to make cars 'fall over' in corners ..........

here's a 330/30/17 'motorcycle' tyre ! bet it handles like .......

She looks ok to me

"darkside' her?????? I'm sure it is something kinky!!!!!!

Interesting article here: http://www.ridermagazine.com/browse-...torcycles.htm/

Fuck off mate. Mo NZ know's best!

Better than these cats feeeeer sure!

As motorcycle safety expert and AMA hall-of-famer David Hough said during our recent conversation on this topic, “Motorcycle engineers get up awfully early in the morning to calculate what works best for bikes. An owner who disregards the engineers’ advice should think carefully about his or her talents in being more clever than the engineers. The owner who installs tires not designed for the task must take full responsibility for the results.”

So you called me out. Now it's your turn. What are your qualifications to be talking about such serious matters that could have deadly consequences ????

So basically, darksiding sacrifices cornering grip for tyre longevity?

And lets just hope it isn't cornered in the wet, where the lack of water displacing tread pattern could be an issue.

I think it does - well Honda/Harley and the big tyre manufacturers seem to think so?

Really?...please, reference this.

I don't "make the physic's stuff up"...I thought it was basic knowledge that when you brake hard, the weight is transferred to the front wheel...and with all that weight traveling forwards, the force is multiplied.
...bugger it!...here

Hence....Each tyre must be able to take the entire weight of the bike...and some!. (its the "some" that seems to be lacking for super heavy cruiser tyres...hence the problems they have with excessive wear and higher failure rates than most)

Reference- Honda don't fit car tyres as standard, the fact that there are tyres specifically made for heavy cruisers if they were underated they wouldnt be allowed to sell them. Yes weight is shifted around and I'm sure bridgestone did their homework. Part of the reason Car tyres last longer than bike tyres because the compound is harder. Bike tyres are generally stickier. Have you ever had a tyre blow out? Is that the reason your fitting car tyres? What about the front - are you going for a car tyre up front as well? Has anyone popped a front tyre from heavy braking on a cruiser?

Its only a matter of time before someone comes a cropper, I would be careful giving out advice on this - its unproven and potentially deadly to yourself and others.

There is no weight force muliplier if that is what you mean, but because under braking it is a torsion and a weight, the tyre must resist both forces; of course they rate them with that in mind.

Mo's bike no doubt.

[Banditbandit]

We typically ride our behemouth two up so the bike is usually punting around 580Kgs down the road. ll

Yeah - I gather that Mac Trucks are also hard on tyres

Wow what a thread, anyone would have thought I'd suggested shooting someone of prominence. So to sum up. Some agree, some don't, some know SFA (as per earlier comments)so all cool.

It is legal to WOF, but depends on the person/company if they accept the risk or not. My insurance company doesn't, won't comment. No reply from NZTA or whoever the feck it was Katman quoted..............who cares anyway. Safety, do it at personal peril. ACC prevents us being sued should fitting a CT cause an accident involving others.

Best thread goes to Allan B with the link to jakewilson.com for well priced well known branded tyres.

What have I learnt? Darksiding is an interseting option frought with unknowns that I simply cannot afford to cover should things go pear shaped (otherwise I'd have on of those new Rushmore 2014 harley waterbus' in my g-rage)

Buying local, not now! only empties my wallet faster so now I'm importing my tyre from the good ole US of A landed at my door for NZ $279!!!!! add local fitting balancing $35, thats with me removing fitting rim etc. SOOOOOOOOOOO my approx saving near on 200 hundy pingers. Front tyres are even cheaper. Sitting back awaiting my bridgestone excedra to arrive now.

Allan B I owe you a beer next time your in town!

Cheers for the comments all, interesting to say the least.

BRO........you rock as always.
