Should be 19" as bob said but easier to get GOOD rubber for the rear in 18" The speedo will be a little out.

Hi stephen, I went for the original look on my 57 Flash. 19" Avon Speedmaster front and 19" Avon SM on the rear. Looks authentic, performs fine.
Regards Huddie
ps you wont get them for £25 though!!

Mitas are cheap & actually OK,
 Cheng Shin, now Maxxis (made in Taiwan, as are my kids) copy the old Dunlop tread pattern, a lot of people will tell you they are junk but I must have covered over 100,000 miles on them ( not the same set!)over an 18 year period whilst living in Taiwan & found them fine & the roads & traffic there have to be seen to be believed! *rant*.
The the ribbed front which I've not seen in the UK was a bit suspect in the wet.
IMHO If you can afford it go for Avon Speedmaster front & SM2 rear but they are more expensive.

I run an 18" back rim with Dunlop Gold Seal K70 4.00x18
The front is a 19" with A Dunlop touring elite mm90-19 61h.
Having an 18" on the back gives you wide access to super sticky sports tyres as well, but personally I feel that low profile tyres, with squiggles and dots on them look really stupid on old brit roadbikes. They need big fat tyres to fill the mudguards properly and maintain the proportions of the bike. The Dunlops are as good a tyre as I or the bike need. I once had a cheapo Cheng Shin on the back that looked identical to the Dunlop, but it never felt good on wet, cobbled streets and wore out damn quick.

If you go with the correct rim size you can run Avon Speedmaster/SM tyres on it, they are widely available. Many people slag them off, but a mate of mine chucks his Goldie about with them on quite confidentally, and there will be people on here who can tell you what you need to know about them. I'm afraid people will have as many opinions on them as they do on oil.
LJ recently posted about some tyres he bought. Have a search.
Cheers,
Iain

Basically I think it largely depends on what you want from your tyres! I'm not a great lover of Speedmasters although I do have one on the back of the Red A10 primarily because it is a great tyre for heavy loads. The wall of that tyre is quite sturdy and can take me, wife and all the camping gear and feel no 'roll' on the back end.

Now my other A10 the blue one I have Dunlop TT100's amazing tyre in which I feel confident in throwing the bike around a bit. My A7 Star Twin currently have Chen Shins and again these I feel are very good tyres.

I've had good deals from Wylde's of Leeds, you might want to look up their website... http://www.cwylde.co.uk/section.php?xSec=3

Iain... That post was about some Trials tyres that someone wanted for their A10 I forget who it was now.

Above all though... Don't be tempted to use tyres that are old even if they are New old Stock it's asking for trouble! http://www.ljswain.btinternet.co.uk/come-off.htm

Thank you all,so for the sake of 30 pounds per tyre,I should go for the Dunlop or Avon.I will only use the bike in summer around town and maybe to the next town 30 miles or so in summer.I have have just measured the rims (ww2 19 Jones) from edge to edge and they actually measure 20" so the 19" must be the inner side of the rim ??,sory o bother you guys,but there is no one else over here to ask.

Hi,er thanks,yes I was joke of the week,but if a different sense.I had my last motorbike theroy lesson today ,and was shocked when the subject of bright clothing and inflatable crash jackets and the right back support kind of protective plate thing came up and it was/ is a must.I´m was planning on just wearing a 50s crash helmet,jeans,desert boots, and thats it.I asked the instructor afterwards,that the bike I was building had no blinkers,he replied I had to put my arm out.??? so what happens if I arm turning right,I can´t take my hand off the throttle to put my right hand out ?? or ? I have tried to order Avon speedmaster and SM mk 2 from the Yorkshire dealer W.. but they d nt seem to answer my E mails.Anyway,the bike is coming on fine,I´ve got diffrent people on diffrent things..still very time consuming and relative expensive and dangerous,hell if my baby beast falls down on me thats 300 Kilos(?) or more  on my leg.Anyway,thanks again for the infos-steve

Hi Stephen
have a look under your throttle twist grip, might be a small screw and nut under there, it provides a friction effect to the throttle so you can let go of it and it will remain at the some setting.
not all twist grips have them and many riders prefer not to use them and let the bike slow down as they signal, comes with experience I suppose, me I like the throttle to stay where I put it while I signal and pray that the following cars driver has fully read the highway code ( are hand signals still in there? ).

Good luck with it, you will enjoy riding once you get a few miles on it

All the best - Bill

Gosh your a braver man than I to use that throttle holder Bill... It scares me to death!

Actually Steve, hand signalling is not so bad once you get used to it. I reckon that one of the most dangerous habits with motorcycling is leaving a electric indicator flashing as you don't always see it flashing away. But with hand signals you would not leave your arm out after a turn! lol Always amuses me when I put my arm out to signal right and the driver oncoming waves back! dear oh dear!

Hi there,
If you're signalling that you are turning you will be slowing down a bit to make the turn anyway..wont you *smile*
I met up with a great bunch of German rockers at a Hemsby Rock'n'roll weekender years ago. They'd ridden their Britbikes across for the event.
Believe me there are guys in Germany riding British bikes and they don't dress like Power Rangers. Their bikes aren't ridiculously over restored things either.
I think you maybe need to track down some of these guys.
You might want to try Vintage Tyre Supply too.
Cheers,
Iain

Agree with Tombeau, if you're signalling you should be decelerating anyway so let the throttle roll off.
Unless of course you are actually overtaking something *wave*
I did manage to overtake a Morris Z delivery van (based on a morris8) the other day *yeah*

Used hand signals to take my test back in early eighties, can't remember if statutory then or because my TS250 didn't have indicators.
 I'm very comfortable with it, change down at the same time, no worries, but do keep an eagle eye out for potholes, they can ruin your day!

Don't think I ever owned a bike in UK with indicators, though they would of been handy on the Ratbike GS750 below, quite different to my current bike *smile* converted from track use it had a Yoshimura 900 race kit, big bore Mikunis K&N's etc. & went like stink, left everthing standing from the lights & shot really cool flames on the overrun, the most fun bike I've ever had on two wheels.

Strengthened headstock no visible frame number, sold it to a policeman *smile* *smile* *smile*
Hand signals with clipons is problematic, but I was usually travelling at several warp factors higher than anything else on the road, so seldom bothered.

Only time I've relied on indicators is in Taiwan (18yrs there) where no one else bothers to indicate or even drive on the right side of the road for that matter.
Pavement ok too in a pinch, traffic lights optional!
You hang on for dear life, brain on high alert whilst driving in what could pass for a computer crash & burn driving game, except of course the stakes are a little higher.
Only time hands come off bars out there is when you prise them off at end of journey & reach for the valium!
