My 1979 R65 needs new tyres for its 18" snowflake rims, if only because the current tires that it came with are over 20 years old.
The Conti Classic Attack by Continental is well reviewed, so my thought is to fit 90/90 R18 on the front, and 110/90 R18 on the rear. My question is whether anybody has done this before, because the 4.00x18 that I took off the rear was tight, and 110 is theoretically is a little wider still.
Does anybody have a 110/90 R18 on the rear of their twin shock R65?
Also, given that I'm not comfortable using the 47 year old snowflake rims tubeless, I'd appreciate experiences of those who have used them with tubes.

Yes it can be done. I am running Avon Roadrider MX ll 90/90/18 on the front with a 120/80/18 on the rear of an 84" R65LS. I live in the mountains of WNC and so far it's been a great combo. As you know it's best tochange out your tubes at the same time you do tires.
Hope this helps.
