The Avon Roadriders are available in inch sizes, they are by most reports a very good tire. Never tried the inch-sized Michelin Pilot Activ's but they look to be similar to the Avons.

I have had S11's and Conti's on as well. The S11's were also a good tire, see Lornce's post for the sizing. Wasn't as fond of the Conti's but tires are a personal thing.

I haven't totally made up my mind on the Avons yet. I don't feel completely comfortable at deep lean angles and I am playing with tire pressures a bit to see.

I only get about 3.5K miles to each set, and that adds up in a hurry.
Most of the time the major difference between an H and V version of the same tire, is initial tread depth.

The V will have less tread depth in order to somewhat eliminate the tire squirm that causes the heat that causes the tire to fail the "V" test.

Given this, I'd expect the H tire to be heavier, as it has more rubber.

H is, in fact the better buy, as no Airhead needs a V tire.

It's pretty academic in any event.

That's what I thought about tire weight too Ikchris.

I wish I could recommend Avon Roadriders. Avon bias ply rubber is much stickier than any other street tire I have used and they last as long or a lot longer than other tires that don't have near the grip. Then they quit making their good tires for our bikes.

The Roadriders make my bike weave badly. Others have reported the same. I have replaced my Roadriders with Avon race tires and the problem is instantly gone and then I can put new Roadriders back on and the problem instantly re-appears. Currently I am running Avon race rubber in front and a Roadrider in back. Just the rear Roadrider brings back quite a bit of the weave but most of it is from the front Roadrider on my bike. I could get the rear Avon race rubber to last 2000 miles versus 3000 or a little more out of most of their street tires. I rarely get more than a bit over 3000 miles out of long wearing rear tires. I am LUCKY to get 1500 miles out of Metzlers and some other brands.

I have installed Roadriders on my own SWB slash 5 and a buddy's LWB slash 5. Both bikes are rock solid stable at 90+ mph, absolutely no weave at all. They are like freight trains. The last person to ride my SWB was convinced I'd converted it to LWB.

Just a data point, not saying that it doesn't happen for supershaft, but it definitely DOESN'T happen for me.

I am following you CD. I WISH I could say the same thing!! I tried three different sets of Roadriders before I gave up!

BTW, most of my Roadrider weave issues are above about 70mph.

One of the tire makers, Dunlop I believe, says if you run a tube in a tubeless tire to select the next speed range up than spec so that would support running V rated tires instead of H. ( V sustained speeds 149+ mph, H sustained 130 mph )Does it make a difference in safety, not likely. My R100 is breathing hard at 110 mph and all done at about 115 and I rarely do that so I am comfortable ignoring the need to upgrade the speed rating.

I ran Spitfire S11's for 30,000 miles, getting about 10,000 miles out of a rear and replacing them as a set though the front had more life in it. They are a fine choice for an airhead offering long wear with good grip. The center of the front tire has a groove that sometimes hunted on grooved pavement or on paint stripes but the forks and frames of these things are rather noodley to start with so wasn't a problem for me. The rear will wear kind of squared off too but again it wasn't a problem for me. This last go around I wanted to try something different so I choose Bridgestone BT45's. I think I had to get a V rated front in my chosen size of 100/90-19. The rear is 110/90. I like the 45's very much, the bike feels better on the side of the tire and it seems to turn in quicker. Hard to tell though, could just be the new tire feel though I now have 3000 miles on them. Lots of miles to go.

Back in the eighties and nineties I ran a Spitfire on the back and a Conti TKV11 on the front of my LS. I could squeeze between 3000 and 3800 miles out of them but I could usually get two rears out of the front TKV. Man does tire mileage vary!

Anyone running race rubber on an airhead is twice, three, maybe four times the rider I am so it doesn't surprise me.

Not sure I ever saw a Bridgestone S11 Spitfire before the late '90's?

How about some nice Duro tires? They have that vintage look and come in the listed sizes...

Conti twin knockoffs. Chinese? I would be suspicious for that kind of price. I like to save money as much as anyone but tires are too important to not get top billing.
