Wheel and Tyre Sizes
 

I'm currently on a trip in Australia on my Tiger 1200. I'm finding the bike to be good for two up touring, but I'm a bit miffed with the availability of suitable tyres. I had a damaged rear tyre (pictured) in a small town and managed to get a tyre sent by courier from the nearest bike shop (180km away). The tyre was a 150 rather than the specified 170, but that was no big deal unless you read the Triumph manual that limits you to 3 tyre types.
I'm now in a larger town with three motorcycle shops and none have a front tyre to fit the bike. Apparently, 120/70/R19 is an unusual size. To get one to me is a 5 day effort. Luckily I'm not in need of the change and was only doing so to put on a more offroad oriented tread pattern, but it has me questioning my choice of advenure touring bike. I'm in a first world country and in a relatively large state with good infrastructure, and yet getting a suitable tyre is a major challenge. If I had a bike with a 21" front and 18" rear this would not be an issue as this seems to be a very common size combination for enduro bikes. Even if the tread patten isn't to your liking at least it will fit and get you going again. I can't imagine having this trouble in a remote corner of Africa and only wishing my rims were a common size. Has anyone else faced this dilemma, and has it affected your choice of motorcycle for adventure touring? https://uploads.tapatalk-cdn.com/202...5c25ed3ccb.jpg

Agreed - I do think it's something to think about, and depending on where you're going, as you note for instance, Africa, it's a very important consideration. Lots of people carry spare tires for this exact reason, but I hate doing that. Way too much aggro, too much weight and a hassle every day dealing with them.
DAMAGE however is not that common, so you could say "tough that out IF it happens, but plan on carrying a spare when it's down to 50% for instance, or 3,000km left, or the next country will be difficult, or whatever your personal criteria are.

Thanks for your prompt reply @cholo. Yes I did ask about an alternative size like 110, but it was the R19 that was the reason they did not have anything in stock. I too, was a little surprised by this. Plenty of 90/90/R21 though.

And found 55 tyres

Not that many enduro style tyres, but several

Rim sizes are very much an influence on my motorcycle purchases.

Silly sizes that limit choice, particularly in a good wet weather/winter tyre I will count as a factor against. Crazy wide fashion styles have stopped me buying.

These shops in the town are MX places though. For 19-inch you need a road bike place and given how few riders wear out tyres even they won't stock them where UPS and accountants make claims about "just-in-time".

Currently the J-i-T pyramid scheme is in a state of collapse due to the pandemic, ships stuck in canals, freak weather, China trying to get close to emissions targets by turning off industry, the collapse of J-i-T tying all the shipping containers up as storage for half finished parts etc. etc. I hear people getting quotes of 12-16 weeks for common sizes like 130/80-17's if they want a particular brand. As a traveller you are better off in rural Turkey than London because the "stockists" there keep actual stock, not a weblink to their distributors (who have a weblink to the maker). From a home base, buy early.

Thanks Eric, I know they are available, just not available in a shop in a town that is close to where I am - and I'm not that remote. If I want to order one and am prepared to wait there is no problem. If I had an un-ridable tyre and I wanted to travel I have a problem with the size I would need. It was interesting to note the availability of the 18" (R) and 21" (F), as that would have kept me going if needed.
