Can't find tire size chart anywhere?..

Tires for a 1.60 x 18 front rim and 1.85 x 18 rear rim, manual says 3.00 x 18 and 3.50 x 18, only thing I can find are dual sport tires like a Shinko 244….. Don't want those.


Looks like 90/90x18 front and 100/19 rear might be the closest I can find in a street tire, but they don't reccomend a rim that narrow.

Anyone have a tire size / rim width chart that includes the smaller sizes?

This for a 1980 450E.

Tom,

There's smaller sizes out there, I know my collector friend bought something super small for a KH 250 not long ago

Nothing in Avon? They at least have a great chart
 
Shows a 90/90-18 is OK on the front, doesn't go that small for the rear.

Looking for the actual Avon chart if anyone has it.
Thanks anyway!
 
Tom,
When redoing my old 450 I used a 90/90-18 front and 110/90-18 rear. On paper the tires are a little big for those rims, but they worked just fine.
 
If I'm reading that other chart right Avon makes the Road Rider in 90/90x18 and 100/90x18. At least they show it on their chart ? Avon shows the 3.50 as 100/90. Is that wrong ?
 
I'm thinking 90/90 and 100/90 are as close as I'm going to find in a quality tire.

They look like original tires from back in the day. Have no idea how they perform. If I was restoring a GS450E to original concours condition as a show bike, I'd put them on it. I know they are very popular with the CB350/360/450 restoration crowd.

By the way, the tires on our GS450E are Avon Roadriders, 90/90-18 up front and 100/90-18 in the back. The back tire is one of the Avon front/rear switch hitters.

No worries.

Like I said in the other thread Tom, do it :D

I'll be doing 300 - 400km's this Sunday on our big ride on the Avons and can't wait!
 
Yeah, if I had an engine I would have bought them already. 90/90 and 100/90 RoadRider I think.

Not interested in tires that look original, looking for tires that grip as I drag my elbow on the road...
 
Yep, can only agree on that, modern tyres are too good to ignore unless it's going to sit in a museum...
