    Car tyres on bikes?

    Just a quick question.

    Is a bike warrantable with a car tyre on the back, not for the pillion, actually on the back wheel?

    Also, would insurance pay out in the case of visiting the scenery due to loss of rear wheel traction in a corner?

    Some of ewes may already know why I ask. Just been into town and spotted a big cruiser outside the pie shop lounging resplendently on it's side stand with a tiny, wee, sidewall contact patch on the road and a huge expanse of tread in the air.

    It's not important, it just offends my feeling on physics.

    Legality depends on tread depth and tire condition.

    I hope the fuckwit who did that also has one of those "retard only" novelty bash hats the gang members seem to favour? Just to justify the picture in my mind y'see!

    I did not make an effort to see the hemlet. The tyre was enough glans for me.

    Looked like a fairly typical cruiser couple out for a jaunt. Full gear, so no bad there.

    I'm just a tad taken aback that the rider cannot see how small the cornering contact patch is, let alone the dynamics of riding a tyre designed to stay in a straight line.

    It's become fairly common in the USA on large cruisers, fortnine did a video on it you can find on you tube

    I know that they do it in the states and call it "darksiding" but they have thousands of miles of freeway over there. There is very little like that here...

    As is often the case ... a good idea may not be that good in hindsight.

    A car tyre fitted to a motorcycle was a WOF fail when I was doing motorcycle WOF'S and still is a warrant fail as below

    d) a tyre that is not compatible with the vehicle to which it is fitted, eg a tyre is marked with any of the following:

    i. ‘NOT FOR HIGHWAY USE’

    ii. ‘NHS’ (Not for Highway Service)

    iii. ‘FOR TRAILER USE ONLY’

    iv. ‘ADV’ (Agricultural Drawn Vehicle)

    v. ‘RACING PURPOSES ONLY’.

    e) a tyre that is not suitable for a motorcycle, eg a car tyre fitted to a class LC motorcycle (Note 4)



    here is link to the regulations if you be bothered reading through the rest of the legislation https://vehicleinspection.nzta.govt....res-and-wheels

    I watched that vid awhile ago and some entertaining vids of darkside incidents on Deals Gap. The results of both kinda prompted me to post.

    A friend of mine did that when we were young, silly, and presumably broke. He can still give a colourful impression of the cornering characteristics of the tyre.

    I've ridden trials bikes with gummy directional tyres. Definitely not designed for leaning.

    Cornering on tar seal was a buttock clenching experience.
