I just put a set of K70s and an 18 tooth front sprocket on my G5. I took it for a short 15 mile ride this morning, cut short by SNOW!!! The K70s definitely make the bike a lot more nibble. Although I don't think they roll quite as smooth as the original tires, maybe because they are brand new (not worn in) or because of the difference in thread. The 18 tooth is a good improvement, especially at high speeds. Overall the bike seems more comfortable in all gears. I would highly recommend the 18 tooth for my fellow G5ers and the 19 tooth for the less fortunate C5 owners ;D

Ditto on the sprocket. I haven't found  a good reason to switch tires, though. I love the feel of the Avon's.

The Avon SM will outlast about 5 K70's from my experience.

The rear for sure, Br.SRL790, I´m convinced that my rear tire will rather mould away than wear out.
But to my great surprise I rubbed out the front within 6300km. The K70 can´t be worse.

Yeah, I've heard that the K70s don't last that long. My front Speed Master was pretty worn after 7500 miles. The rear Safety Mileage was still in pretty good shape, probably could have gone another 3-4000 miles. I wanted to go with some tires that had more traction on loose surfaces and had a more rounded profile in the rear. Also, I wanted tires that had the old school look to match the my G5.

Chris G 5;   i am not sure from the text of your reply what tires you chose.  You said "I wanted to go with something with more grip on loose surfaces....and more rounded profile on the rear .......with appropriate retro look...."    So what did you come up with , and how do they work (on loose surfaces )    Thanks Nigel

I was talking about my reasoning for going with the Dunlop K70s. I haven't tried them out yet on any loose surfaces. The weather around here has been cold and snowy. I might take a ride today if I have time.

Not sure if it is of any interest here, but the Ural forum talks about two other tires in 19" size, .  These are "dual purpose" off/on road tires, and in the particular case of the Ural side wall stiffness and stability are something of an asset due to the lateral forces brought to bear by the sidecar espectially on the rear "pusher".   Here are the links

The Heidenhaus seem to be favoured in the dual purpose 19 inch format



   Anyone have experience of these on REs?      Nigel

Avon Roadriders make a superb alternative to the Speedmasters. They not only offer better grip and sportier handling but from the accounts of front wear here wil last longer too. I've done 8,000m on my G5 and they're not even half worn yet.

 +1 on the handling & grip of the RoadRiders - you can really chuck it about with these tyres on! Can't yet comment on the wear - but about 4000 miles on mine so far and still looking good.

I replaced my rear AM26 at 6,700 miles, the front might make 10,000 miles before it's done in. The 19's on a G5 should last slightly longer than the 18's on my C5.

Those Duro's are a nice looking tire.  Big blocks for traction on dirt but not a total knobby for the road.  If I were inclined to occasional dirt that's what I'd look for but I just stick to the pavement with my C5.

Another tire :   grist for the mill


http://store.cokertire.com/350-19-coker-e70k-motorcycle-tire.html

This is more of an all round vintage type tire, from, I believe a US manufacturer



And the Heidenhau link I gave did not specifically lead to the dual purpose tire I was thinking of (the one the Ural guys rate highly) so here is the more specific link


http://www.heindlengineering.com/Online_Store/heidenau_tires.htm

Seems there aren't too many companies making 19 inch tires, but still. quite a range of choice and growing as the retro market expands.   At one time , I gather , Avon was about it, because brit bikes were all but non existant outside India and Russion Bikes hadn't yet got of of Russia.  The Heidenhaus and Duros are both rated by Ural users as much more durable than the original manufactureres Russion Rubber, but I think Urals now come stock with Duros.      Neither of these, of course is a high lean angle performance tire, but may be of interest to those who want to use their Enfields the way they are used in India -on poor or non existent roads.   The Cokers seem to be fairly highly rated (new in this size as of about a year ago I think) and would appeal more to the performance/pavement lean angle crowd:  I be live they may also be available in whitewall.    Nigel
