More tires!
« on: March 12, 2013, 11:48:05 PM »
Almost as bad as oil threads!  ;D Anyhow, I've been running K70s but I'm not happy with how fast the rear tires wear out (about 3k miles). So I dug out my stock rear Avon Safety Mileage tire and tried it with the 3.25" k70 front. The match is really great. Very neutral steering, light effort carving of turns and no understeer or wash outs that the speedmaster front tire did. I'm expecting to get about 10k miles out pf the rear and 7k out of the front.

That stock front Avon Speedmaster looks great on a show bike but few people like them.  The rear isn't the stickiest but has a good lifespan.

I think you hit on a good combo.  It's ok to match a sticky front with a less sticky rear but not the other way around.  The idea being it's better to lose the rear than the front if you get to the limit.  Plus now the rear life should match the front better.

The C5's Avon Road Riders are pretty good tires and mine still look good after nearly 12,000 miles.  Still, I'll be trying the Bridgestone Battlax BT45s when these are done.  They're supposed to be great in the wet and I'd like to see if they're better.

Well, this helped make up my mind with my tire decisions when I get home.

Glad to hear this combo works well.

Will the 19inch tire conversion for C5's with the early fork not the new one like the B5's have help stabilize my 2011 C5 at speeds above 65 just in case I decide to hit the interstate? I had to ride due to a family emergency on the interstate for some distance and I didn't enjoy it. I wouldn't like the interstate anyways but would be less hectic if I had better control. Ok so if it will then what would be the better choices for a tire for the 19 inch conversion? Any certain brand have better control?

I don't know if it will help with the stability issues or not but if you change rims/tires, avoid that grooved SpeedMaster.
It is the kind of tire tread that was commonly used back in the '50's but they don't provide very good traction.
Maybe that was OK back when a 380 pound motorcycle had 6 inch drum brakes on them but with today's brakes and the speeds we commonly ride those tires leave a lot to be desired.

+1 on that !

Also those grooved tires are hazardous on interstate super-slab with rain-grooves raked into the concrete.

I really like the Dunlop K-70 on the front.  It burns out too quickly on the back, but, it is fine up front.

The ribbed Avon Skidmasters should be banned. I don't even understand why they are still made. Must be extremely cheap to OEMs

The grooved Avon supplied on the RE's looks just like the grooved Avon's that are shown on the front of most of the old BSA's, Triumph's, Velocettes, Matchless's and other British bikes photos from the 1950's.  They are a classic design.

Of course, back in the 1950's, 60 mph was the speed limit on the high speed turnpikes in the USA and was probably way over any legal speeds in the UK so maybe the grip wasn't as important as it is now.

And that's where they shine best, on a vintage show bike on the concourse.

Jartist, I was thinking of trying the combo you have on your bike, but I wasn't sure if it would handle well. Thanks for the post, I'm ordering A K70 for the front. cochi

So do u guys recommend getting the OEM Avons off right away, or ride them till worn? I haven't fallen off a bike since I was about 19 and have no wish to revisit that day. 650 Triumph with knobbies on pavement! Was I smart or what?  Okay....or what...

In my humble opinion, replace the Avon Deathmasters as soon as you can.
