Converting a rear wheel to accept a car tyre.....

just buy harder tyres . a car tyre will let you down , JUST when you need it the most.

you might get away with this in america , but the traffic cop who turns up o investigate your crash , will nail your bollocks to the wall .

I think mine is the perfect solution for the ultra high speeds possible in Mexico and provides safety in numbers - say 93 bar (or 1400psi)
 
Anyone who has over warn a normal bike tyre which is squared off a lot, will know how it affects handling.
Imagine a REAL square tyre!
 
How about fitting 4 bike tyres to a car? I can’t see any benefit but way ho could someone just do it? Should be fun. JJH
 
I used to commute on the motorway so I could filter through the traffic and park the bike for free right outside work. Squaring off the rear tyre was a pain and costly so I feel your pain.

You might be better off learning how to change your own tyres and then picking up bargains in bulk when they come up. Even a cheap out of date brand would probably off more grip than a car tyre.

A few hot rod cars run on bike tyres but usually only on the front.
 
Youll get 10 to 12k miles out of a DunlopTrailmax Mission rear - look on YouTube , yanks love them for long distance adventure riding / travel .

If saving £150 every now and then is a big deal....just get a smaller, lighter bike....

But it isn't 'every now and again' ......

50k miles @ 1k miles per week = one years riding.

50k miles @ 5000 miles per tyre = 10 new m/c tyres @ £200 per tyre (fitted, balanced.) = £2000.

Compared to one car tyre with a life expectancy of 50k miles costing £50.

So, in the interests of saving approx. £1950 per annum on replacement tyres, I think it is at least worth raising the question in order to get the views of others.....

Other than on the rear of a sidecar outfit for use on UK roads it is not legal nor safe to put a car tyre on a bike, it will no doubt also have insurance ramifications in the case of an accident (especially a blameworthy if someone claims personal injuries).

However, if you chose to do it the bike will fail an mot , it will no doubt ride like an utter pig and most probably drop you on your arse when cornering in wet weather and very probably get you points if you a stopped etc etc.

Just don't bother saying it was a bad idea when when one or all of the above happen.

your putting your own safety at risk to save money.

My advice is not because i want to take the piss.
Its because i don't want you to become another statistic.

I just answered honestly.

Let me put this another way.
If your Son asked you the same question, what would you say?

You do 50k miles a year ? No, as you typed that a new Metzeler would be toast in a few months time...not 5 weeks time.
Anway....you could get way more than 5k miles a year out of many different tyres on a 1200 GSA (I used to get 6.5 to 7k out of tourance/PR3 and PR4)
Would I spend £2k a year on motorbike tyres for my motorbike or a car tyre?....£2k year in year out. For all the reasons given on this thread. It WOULD fail its MOT, it would be dangerous many times on any given ride. Stupid idea.
5.2.3 on the below. Major for unsuitable tyre.

Fit heidenau K60 Scouts

10,000 miles or maybe more with ease

Not always comfortable but decent tyres
 
This being the actual law bit and as I stated at the beginning of the thread.

Examples of an unsuitable tyre are:

  • a sidecar or car tyre on a solo motorcycle - sidecars may be fitted with either car or motorcycle type tyres
I know there’s so few cops around but a half decent traffic cop will know this and see it, and doing 50k a year your bound to get seen at some point. And who knows what your insurance company would say should you ever have to make a claim for whatever reason.
 
forget not having ANY insurance
forget not having an MOT
forget all the prosecutions for not having a legal tyre

it will be

1) disgusting to ride
2) dangerous to ride
3) ruin ANYTHING that was ever was good about riding a motorcycle
4) likely mean you'll drop it causing very expensive body work damage
5) over years of hell, quiet likely wobble whilst filtering and clip a car, thus have aggro with their insurer
6) might injure yourself falling off, add in loss of earnings, paying for new gear. other repairs etc.
7) if causing a fatal accident due to stupid, illegal modifications, get 10 years Jail for death by dangerous driving (recently modified so this would qualify)

all those cons, to save £40 quid, what moron even allows these threads to exist ?
 
The dims of a bike tyre and car tyre differ slightly at 17". The 150 section rim is a bit slim to suit a 175 / xx / 17 car tyre. I've just fitted such a tyre to a cast rim off a rockster I think it was which would ordinary take a 170 width tyre. I used tyre paste liberally. When I pressurised the tyre there was no 'pop' as the tyre seated over the bead which tells you something. For a sidecar which stays flat lots of folks have taken the chance and fitted car tyres. Would you really want to lean a car tyre over onto the rim when you can't be sure it's a snug fit on the bead?

Longer term I'll be fitting car wheels to the outfit but there is quite a bit of bespoke engineering to make that happen.

The simplest way would be to fit a cast wheel from the RT. Then you can fit 175/70/17 or 175/80/17 tyres (I think those are the dims). But they are not a "common" size say like a 205/17
