    due to the surface conditions here in NYstate im looking for new tires with much more aggressive
    treads similar to dirt flat track or enduro style
    not much choice out there in 100/90-18 but several good possible at size 110/90
    i really dont want to modify the fender but would like to know what anybody has
    done in this situation and should i stick with non radial tires
    i been down on the ground on this bike 3 times in 2 seasons
    each time at lower speeds and the front tire slid out no warning.Bang!
    now recuperating from shoulder surgery (Storm Grate)
    This never happened in all my years of Triumph BSA K70 dunlop
    i see scrambler styl bikes popping up with dirt tires so i think this is
    doable let me know your thoughts and suggestions

    Check with your dealer on the factory Scrambler tire options. I'll try to post info on them tonight.

    Given that you apparently live in Brooklyn (Red Hook), it isn't entirely obvious why going to dirt flat track/enduro tires will make the crashes you describe less likely.

    Or are you not riding in the city?

    Which bike (sounds like a Stone from your first post), and what tires do you have on the bike now?

    As far as I know, there aren't a lot of people riding V7 bikes in New York State, let alone New York City, who are blaming front wheel slides on New York State roads and their tires. In fact, you would appear to be the first.

    Maybe avoid storm grates?

    i live 100 miles up river from Brooklyn. the roads i ride on were here way before the wheel
    and some havnt improved much since then or last winter. riding bikes under 400 lbs since '71
    This Stone has it all, just needs new tires. and a better deal on clutch levers

    I have a 2001 EV that uses 110/90-18 front and 130/90/17 rears. the rear is supposed to be a 140/80 but it's easier to find a 130/90. I use bias and always keep a set of extras on hand. I want to try these when my new 2015 Stone wears out it's first set. I can't believe they won't fit right in both locations. just FYI my current EV set are the Bridgestone S11 and so far I am pleasantly surprised. they will do at least a 1000 more than any other tire I have ever tried in 160000 miles except the dearly departed Dunlop 491.
    I have a set of Shinko's to try #230 I believe. I got them before I realized how good the S11 would wear.

    I just re-read the first post. Storm Grate? Rubber and steel don't mix. Tyre choice won't make a difference. Riding style will. Bigger tyres will not help and larger numbers don't necessarily mean larger contact footprint. In fact the opposite is quite possible.

    Try rolling a rubber ball smoothly down a piece of steel.. doesn't work.

    It's a basic law of biking. Avoid anything steel, metallic, painted or shiny, or cat eyes.

    Tyres are a personal choice. If you're confident on a particular brand/type... that's perhaps better than being shit scared on a premium brand/name. The latter will end in tears one way or the other. At least with confidence you can focus on skill without the oh-shit factor.

    Not sure if this helps but anyway .... hope you're keeping clear of storm drains.

    BSAndy, did you decide on some new tires? What and why?
    You did not say what tires you had on your Stone. I have read that the Lazertechs the early V7s came with were not the greatest and that the Speed Demons were much better.

    I'm looking for some 80/20 dual sport tires for my Stone. The scrambler/Stornello tires are tubeless, so they would work, the question is "how well?" Stornello and Scrambler owners - how are they? on pavement, in the twisties, and on dirt roads? Most of the dirt I ride you would take an ordinary automobile on, but occasionally something a bit rougher, perhaps wanting a high clearance vehicle but not needing 4WD.

    I like Shinko 705s (they were my first choice) and have used them on other bikes but they don't make a tubeless 18" front. The Kenda K761 is similar and comes in the right sizes & tubeless; anyone have experience with them?
    Pirelli Scorpion Trail IIs come in the right size but they are 90/10s. I had a pair on my Stelvio (a different weight class) and they were fine on the road but the front started cupping early (maybe by 2000 miles). I want tires a bit more aggressive.
    The Ducati Scrambler uses Pirelli MT 60 RS; the front is the right size, radial, tubeless, but the rears are too fat.

    So far, the choices for a matched pair of 80/20 tires are the MG scrambler tires and Kendo K761s. Any other options?

    BTW: Looking at the V7III specs they listed the front tire size as 100/90-18 or 110/80-18.

    Everyone -- What dual-sport tires have you tried on a V7, and how did they work?

    I'm in the process of switching to the Heidenau K60 Sports. Unfortunately they don't make a tubeless type for the front wheel, so I'm going with tube type for both. I'll look for a tube with the same right angle valve. I went one size up for the front. Instead of the stock 100/90 x 18, I got a 110/80. Looks like it's going to fit just fine... IMG_9630.JPG

    On the V7III brochure they list 110/80-18 as an alternative size.

    Ahhh! That's good to know. They only make a tube type for the front, and a tubeless for the rear. I will run tubes in both with right angle valves. Having a mis-match would drive me crazy. Hate having to use tubes, but it's the only option. Unless I run the front tube type tire without a tube. Seems to be controversy on that one, and I don't want to risk it.

    When it's time to change tires I will be putting on the Avon AV54 TrailRider.
    Their 110/80-18 is a "rear" tire; Their front tires in this model have 5mm thread depth, the rear tires have 7.7mm per the US chart or 10.5mm per the UK chart. This extra tread depth can affect handling. Mount this tire "reversed" when putting it on the front.
    Earth-Roamer has a great report on their experience with these tires.

    I would still go tubeless on the back. If you run a flat it will most likely be the rear and it would be easier to fix on the road with a plug.

    I would have said it was about 50/50 which wheel will puncture......maybe on probabilities it is slightly more likely that the front wheel will puncture as it will pick up the nail and stop it reaching the rear wheel!

    Talking with experienced riders it is 90% rear, 10% front.
    Popular theory is that the front flips up the nail/screw/whatever and then it gets stuck in the rear.

    The only time I've ever gotten a flat was a rear. Although it totally makes sense to go tubeless in the rear , the problem is my OCD overrules practicality. Do I really want to look at two different valve stems? Ugh...

    no new tires yet still trying to decide. maybe this week
    btw never had a flat in front and been riding since 71 but had a couple scary back flats and once a back blowout on a kaw 750 triple
    with my buddy on the back. got it down to about 15mph before it dumped us in the ditch.
    my 650 bsa had a nice leather flap hanging down to the road at the pivot of the swing arm to prevent kick up into the rear

    Over the years (+40) I have had punctures in front and back tyres - thankfully no blow outs - and if there are more punctures in rear wheels maybe it is because the rear wheel carries more load? Or because riders often seem to let their rear tyres wear away to nothing! Never seen a bald front tyre, but I have seen rear tyres frequently that are 'well worn".
    Modern tubless tyres are much better than the tubed tyres - I bought a Stone rather than a Classic as the Stone uses tubeless.

    i love my rims, no spokes im leaning towards the Conti tkc70 130/80-17 back tire
    can anybody post more specs on the stock MG scrambler tires ?
    also can radials mix with bias?
    i also like front pirelli mt60r 110/80 18 but maybe its a little too aggressive for this bike
