Trying to purchase new tires and my choice was Avon Mk II Roadriders or AM26 roadriders on 100/90-19 size. Everywhere seems to be sold out and I was told there won't be any until next year !
I noticed that some are using Conti and michelin, Bridgestone etc but they don't come in this size. Are you using front tires on the rear or?

Did ya try Walridge Motors ?
 
Last Monday I ordered a set of Michelin PR4’s with tubes for new to me ride at local shop ….. usually order Monday , here and mounted by Thursday , no sign of them yet , young guy st desk told me sourcing tubes had become an issue …. Keep looking Walridge or even Britbikesupply May be able to help , good luck !
 
Guess I’m old school we have only two small local shops plus a quasi one on edge … like to see them all remain in business , do I try and support them as much as possible ….
 
I don't know how it is your side of the pond, but when I wanted a new Roadrunner over here, because I was fitting it myself the local fast fit car tyre centre ordered one for me. Just saying that if you're trying for Avon, doesn't have to be a bike related dealer, perhaps??
 
Thanks for all of the replies. Fortnine shows them as in stock until you click add to cart. They did have one left so I grabbed it and found a 90/90-19 elsewhere which I will put on the front. there is a definite shortage this year, My regular supplier, Pete's Superbike in Montreal told me that there is a shortage of material so the less common tires are not being made. He reckons it will be next year before he gets any more in.
 
I just received my tires this morning - 100/90 - 19 Road Rider MK2 from International Tire Consultants in Surrey BC. Distance is an issue for you, but there were on order about 8 weeks.
 
I recently bought a couple of Avon Roadriders for mine - here's the list I compiled in order to help with selection.
No Michelins on the list as I couldn't get the local distributor to confirm dimensions
Cheers

Update to include Michelin data I received today:
(their "Road Classic" looks like a reasonable alternative!)

Thanks for the effort with the list. I get frustrated trying to find specs and wish they would also tell the tire weight. I wasn't aware of half the tires on the list, have some other other old bikes to try them on. I searched for the michelin 100/90 19 and revzilla shows it and a 3.25 19 54H also but no specs. None of the rears were available. The Continintal Classic is what I would like to try but weren't available last time so went Avon
 
Some time after the last ice age a good friend called my and asked for my help installing new tires on a T140D. He said if I came down (to Cape Cod) he would pick up the tab for the entire evening while we painted-the-town-red, even told me that he had a retained lawyer incase we had too much fun...

Anyway, I got there and found a pair of new sneakers in sizes 4.00/18 for the rear and a 3.25/189 for the front. Both tires were directional and I noticed that the 4.00/18 was a front tire. I called Moore's in Hartford and told them about the error and asked if we could shoot over and get the correct rear. Keith Moore had picked up the phone, it was early Saturday morning, and told me that by reversing the direction of a tire the 4.00/18 front would make it safe for duty on the rear, said that by doing so the tires construction and tread pattern would work fine on the rear. Keith went into some detail which I don't recall, but this post IMO is the perfect place to hear from members with greater knowledge. Keith Moore was a legend in the motorcycle industry he made me feel valued and respected while trying to convey his knowledge to a mere troglodyte; they don't make 'em like that anymore.

Back then tire choices were slim; nowadays I simply buy a matched set and the only thing that reverses is my bank balance...

So,, does this technique still have a use? I'd really like to hear what members have to say.

My friend still lives on the Cape, the T140D never hurt him, he sold the Triumph a year later. He still rides, but on a '66 BMW R60/2 which I woke up for him after a 25 year hibernation.

Best.

I posted this in a thread not so long ago - hydroplaning is the real reason. The thread linked below has some good research/references in it.

"I had a set of Avon Roadriders installed at a dealer once and they mounted the front wrong. I wasn't sure if it was a big deal or not a big deal so I called Avon Tyre, they told me the tread pattern on the roadrider was designed to shed water away from the back tire and being mounted backwards, would not harm the tire for grip or safety or even handling, but it would reverse the water direction and funnel it all to the rear wheel. and since I am not a pansey and ride it torrential rain to get places I went back to said dealer, told them and they re-mounted it correctly as the risk of hydroplaning was increased a lot. They have universal front/rear tires and have instructions to mount in one direction for front and the opposite for rear because of water shedding etc. This is the roadrider tyre only. I did not ask about any other model"

So - what direction should a Roadrider (100/90 19 57V) universal be installed on the front?

Thanks, I remember now; good thing my right wrist instinctively remembers which way to turn the twist grip when a picturesque road need to be turned into a test track . I only did the reverse once, and not being a tire designer/engineer I purchase the best tire set that suites the average speed and the degree of madness that give me the greatest safety margin (safety and motorcycles are rarely associated terms) For my Commando an "S" speed rated tire would be fine; I do prefer the "H" rated, but the "V" rated tires have a stiffer sidewall that take greater side loads making the handling more predictable for me as the pegs start salivating, wanting to mark their territory..

Moore said something about braking versus putting power down; I don't worry about hydroplaning because if I get caught in the rain I sometimes get passed bt Toyota Prius or two; live to fight another day...

That would be the ply unwinding reasoning explainedin the linked thread.

"The other big reason for noting wheel direction has to do with the manufacturing process. The tread rubber is initially a flat strip that's cut to length, at an angle, and then spliced together with the two ends overlapping, creating a hoop. Under acceleration, a tire mounted backwards will try to peel back this splice. The opposite is true for the front wheel, where directional forces are reversed under hard braking."

In my opinion, this is backwards reasoning. All tires are built in the same manner. Why are not all tires directional? Simply because they do not delaminate if run in "contrary" directions."
