    Default Anyone try the Avon Cobra Chrome tires yet?

    I've seen a few threads talking about their availability, but not that anyone has tried them yet.

    I had run the Pirelli Night Dragons on my previous 109 and was really happy with them. I am considering the Cobras because I'd like to go with the 260 to get a little more height in the rear. Looks like the tire will provide better dry straight line traction due to less grooves in the center of the tire than the previous Cobra tire. I'm interested to see what the opinions are on corner grip, as the Cobra Chrome looks very similar to the Cobra with regard to the grooves at the edge of the tire. Is it better, worse, or unchanged from the previous Cobra tire?

    With all the good reviews on the previous Cobra tires, I was pretty much set to try them when I change tires. Now with the tread pattern/design being a little different on the Cobra Chrome, I am back on the fence. My main concern is having a sticky tire, not longevity.

    I've got the Cobra Chrome on my front 21" wheel. I was going to get the matching 260 for the rear but was told not available until May. I've only put on about 200 miles so far.

    I've installed the front tire and awaiting the rear 280. There is a different feel to the new Avon verse the old. It corners a lot easier. Shouldn't make a difference but there is a difference.

    160/250 Avon CC's here (not a fan of the 260/40 geometry vs. stock) but only been on it for about 5mins to drive it home from the shop! Its been snowing or cold or raining (AND cold) just about every day since... and now my extended forecast shows rain basically every day for 10 days. Gah.

    So... I'm wearing them... but still have no idea what they're like yet! Ha.

    Managed to order the cobra chrome 260 today and over here it is cheaper than the 250 so we will see time will tell.

    What didn't you like about the geometry? The way the tire fit the stock rim, or the geometry change of the bike?

    Hi Kratos.
    I'm a victim of my numerical OCD.

    A 250/40 is +1.2% larger in circumference and diameter from a stock 240/40, giving "-9 revolutions per mile".

    A 260/40 is +2.3% and -19 rev/mi with an enormous +7.9% sidewall also - most tire references for cars suggest you stay within 2% of stock cir/dia dimensions for safety due to geometry/ratio reasons; I can only suspect this is even more important on a bike.

    A 280/35 however (which I feel should be on a 10" rim but some ride it on stock) has nearly *identical* dimensions to stock, except of course for width: +0.4% cir/dia and -4 rev/mi.

    So I am ok with a 250/40 but would actually prefer a 280/35 if I had a 10" rim to put it on. For the extra 5mm per side to go from 250 to 260, I am personally not comfortable with the altered geometry/ratios.

    To each their own though - lots run a 260 just fine.

    Put an Avon CC 250 on ~ 2 weeks ago. Have probably put about 400 miles on it thus far... so far very happy with it.

    I completely understand. Coming from the sportbike world, I'm used to changing the rear tire size, going from a 190/50 to 190/55 to 200/55. I'm fine with it as long as fitting the tire meets the manufacturer specs, which it does for the 8.5" wheel of the 109. Cobra's specs say the tire is designed for an 8.5" - 9.5" wheel, so that gives me the warm fuzzy that it would be ok.

    Thanks for the pic Mythos, that tire looks pretty good. How much room do you have on either side before the tire would rub?

    I hve run the 250 for a while now and there is plenty of room I am looking to try the 260 to see the difference and over here it is cheaper than the 250

    You'd never have a problem with 250/260 rubbing. Even 280. The 300 is where you have to mod things

    The 260/40-18 has just become available at Revzilla, so I went ahead and purchased the 130/70 and 260/40.

    Nice! Hope all goes well on your trip. Will be interested to hear your evaluation of the Cobra Chromes.

    It will do that as it bulges out and makes it more rounded. I've had nothing but the 260 on the back end since I got the bike 3 years ago. It actually measures close to a 250 but it lifts the back up end up.

    I have used cobra chrome 260, I felt better experience than previous, more better grip and gives premium feeling, Even i have used in the trailer which i use for 24-hour Roadside Assistance service, the overall experience was good and i would recommend to use.

    I have now put around 3000 miles on the cobra chrome 260/40/18 and standered size front i am personally very pleased with the feel and overall performance and would recommend

    I'm glad this popped up again because I wanted to mention - my 250 Cobra Chrome... well... not as impressed as I had expected.

    This is my first new rear since stock, so I'm not 100% certain if it is my increased assertiveness now that I am more comfortable with the bike or the compound of the tires which is my concern. I have noticed that the rear will break away *far more* often than I ever recall with the stock Dunlops until they went bald, after which they were sliding all over the place.

    My only observation this season on the Chrome is that I seem to be able to break it off the line very easily now, and I have had it let go in 2nd under torque a few times. No biggie, easily controlled... but I just don't recall that with the stockers and again - caveat: I may be riding harder now than I was before, so it isn't a very scientific comparison.

    Unfortunately because of that however, I have not even attempted to press them in the rain as yet.
