Hi everyone

Really stupid question, I'm trying to on replace a rear tire on my 1979 gs850g.

when I look up what the bike should have, it seems to have:

4.50 17.

when trying to look for a tire, it seems that newer tires use other standards of measurements

I tried to check compatibility lists and it shows 120/80, 120/90 or MP85.

I do not seem to find the tire in size 17 which seems to be what the bike would have on it.

does anyone have a suggestion ? (Im looking for reasonable price too)

thanks

sean

If you want a cheap tire (that is still decent) and don't mind changing it a bit more often, Shinko 230 Tourmaster.

If you want to change your tires less frequently, Avon AM26 Road Riders.

Feel free to step up one size to increase your selection. Front tire should be a 100/90-19, the rear can be a 130/90-17.

Avon is still having sidewall cracking issues on their Road Riders.
 
what about tire max load?

My bike shows as being 601lbs wet.

the tires I keep looking at seem to be rated at 675, or 827 (for the tourmaster 230's mentioned).

so according to my simple math skills
601 lb bike
250 lb rider

= 851 ?

so too heavy for the tires ?
 
Perelli sport demons...I love them. I run Avon Roadriders too. Got 14000kms on my 1100 out of the last ones.:)

When did you switch to Sport Demons ? I currently have 12,000 on mine and the rear wear bars are just starting to show.
 
I have a 17" rear Avon Roadrider if you are interested. No longer have any 17" wheel bikes. Never been mounted, date code is maybe three years old now. If you are interested I can look it up.
 
I may be interested, I'll PM you.

My 1100 needed tires back in November after putting on 14000 on the Avon's. They were out of stock for one of the sizes I needed and I have thought about trying the Demons. So I did. I like everything about them, look great, handle even better and great grip. I'm sure the down side will be that they don't last as long but now having the beemer I won't be putting as many miles on my GS bikes. Plan to switch the 750 over too when needed.
You coming over to the Coombs swap meet? April 6th

Didn't know about it. Weather permitting, sounds like fun. I'll see if I can talk Andrew into coming with....
