I need help to decide on which tires to finish a 2nd restore of a 69 RS with a A65 1967 650 engine, ( More post about this?) Anyway, Just doing a restore of a 40 year storage bike i built when 26 years old. Thank God for this Forum, Learning tons everday i read. The to do list keeps expanding. This restore is to try and get more authentic and rideable and update the 67 engine ( probably better to update the original A50) Maybe. My Question is about chooseing a new rear tire, The new front will be be helped with the new rear. 40 years ago i was advised by dealer in Canada to put on a 4.50 by 18 Lien Shin on my rear rim, with great cost savings and away i went happy, got my bike on the road, In 1 year of road riding the back end slid out and bike on its side 3 times in a corner, twice in wet, once maybe to fast. I rode dirt bikes a coulpe of years before this. I,m thinking my choice back then to install too big a tire on such a smaller rim was a big factor with rear spin outs. Becuase the lien Shin was also a knobby tire, I,m hesitant to go back with the Dunlop knobby tire and instead go to the Avon Roadrider MKII
.
I realise there is many criterea with many members on this forum, And have read most of them, I,m just looking for a gut feeling , Cause this tire choice is next to procceed

RS? not familiar with that. IMO 4.50 is too big. You have a choice between Dunlop K70s ( look original, not great on the road), K181s/ TT100s, better than K70s, Avon Roadriders , my favourite , wear and grip well.

Im guessing RS = Royal Star?

I used to have K70's and they were "ok" but not great, wore the back tyre out very quickly and when fitted to an A65 wouldn't like being leant too much into a bend.... Same tyres on my Can-Am (as was) handled brilliantly... But even a set of trials tyres with 10psi in handled well on that bike.

I switched to Road riders and the first trip out was in the wet. Immediately filled me with confidence and this was after putting the bike through a long right hand bend on a very wet road.

I have a set of the Mk2's for my OIF Thunderbolt, so I will be interested to try them.

One thing I will say is the K70's were much better on gravel roads than the RoadRiders, but I don't go on those too often anyway.


Now let’s all have a beer beerchug

68’ A65 Lightning “clubman”
71’ A65 823 Thunderbolt (undergoing restoration)
67’ D10 sportsman (undergoing restoration)
68’ D14 trials (undergoing transformation)

There might be something available in the size you need from Heidenau. I remember there were some that had a more vintage look if you preferred that.

Thanks to all that took time to respond and write their opinions, Yes Its a Royal Star, I was having a difficult time to make up my mind, I was edgeing for the Avons, Just reading from your experiences was a big help. 2 Avon Roadriders MK II,s on order, Even found a dealer in town that can supply them, So saveing on shipping. Thanks Andy
