Falcon 81 rim and tyre size..

Post  john87 on Tue May 10, 2016 10:48 pm

Hi all,

What is the correct rim and tyre size for a Falcon 81?? [I got two]

The one came with a 19" rear wheel off a cruiser apparently [which is obviously wrong] as it should be an 18" Anyway, the rim is a WM2 and it had a 3.25 tyre on it

The front meanwhile is an 18" WM2 also with a 3.25 tyre Is this correct?? It seems a bit wide to me and the tyre is very very close to rubbing the mudguard bracket..

I now have some [very nice!!] new wheels i have just bought] to go with my "other" one, [It had no wheels] The rear is a WM2 and the front a WM1. This seems much better..

What would a falcon 81 have as standard???

John,

The Falcon 81 was specified with an 18" WM2 36 spoke rim front and rear, and a 3.25 tyre front and rear. I had problems with a modern Dunlop K82 tyre in size 3.25 and Dunlop confirmed they are wider than a 50s/60s 3.25 tyre. I had to fit 3.00 K82s which fit perfectly and look right size wise.

regards,
Steve.

That front mudguard brace can be a problem.i suspect they may get a little out shape over the years. A little work in the vice can help
Mine on my falcon 87 is only about 3/16" from the tyre both sides. It does make a difference in what position you have it clamped as if it's narrow point is next to the tyre wide part . Stand back and see if your guard has the same radius as the tyre and wheel all the way round.

Has anyone tried Mitas tyres?? or cheng shin?? Might look a bit out of place though... I was hoping some of the cheap sizes might have a more traditional profile.

Seen the price of things like Dunlop!! They can dream on, not far from the price of tyres for my Suzuki that is twice the weight, ten times the power, and faster in first gear...

One of the less expensive tires I developed an interest in is the Michilin Gazelle, which is inexpensive and surely tire enough for the awesome, pavement ripping power of a 197cc Villiers in full cry! It is a 3.00X18, but of the more modern shape, re: bulging sidewalls. Tread design is more of a universal design. I have heard good things about Mitas, quality control has been called out as a little sketchy on Cheng Shin. I'm running Pirelli's lowest price tires on my Suzy-Q TU250X. A terrific upgrade. I promise not to bore you all with tales of my 1938 Indian 80 inch Bonneville Chief, that I owned when F-B was trying to convince the world that the Piatti designed engines were the perfect answer to the worlds transportation needs.

I have used Mitas tyres recently on a pre war New Imperial and Cheng Shin on a Honda CD200 I prefered the Cheng Shin but that might just have been the difference in suspension. The handling on the Honda was much better original tyres looked OK but were 30 years old and the rubber had gone hard.
I think you will be fine with either its not as if we are going to do many miles at motorway speeds.
