    How does a Dunlop D803 radial compare with Michelin radial. The Dunlop is new, 2005 vintage. On a Scorpa 4 stroke. The original Michelin is cracking and tends to leak.
    Thanks, Chris

    The guy I picked up my Montesa 4RT from put new Dunlops on it (D803) on it isn't bad, but, I do like the Michelin Competition on my wifes TXT Pro a bit better. Just my 2 cents...

    I expect that the difference between an 8 year old Dunlop and a fresh Michelin woild be quite substantial, depending on how it was stored. I much prefer the Michelin over a fresh Dunlop. I use the Dunlops on my trail bikes and Michelin on my Trials bike.

    Thanks for the replies. I'll probably go ahead and use the Dunlop as I do more trail riding than trial riding on that bike. Any helpful hints on mounting a tubeless tire? Have done lots of tube type in the past but always had a pro mount street bike radials.

    Hints:

    It will take a lot of pressure to seat the bead. Be careful.

    It will go BOOM when the bead seats. Be ready. :D

    Dunlops are good tire, especially price wise. Michelin X-Lites are a great tire (grip wise) for advanced riders especially, not much to gain in novice up to above amatuer classes, I think, other than they are slightly lighter in weight...

    I believe the Michelin wear pretty fast, and have experienced leaks around nobbies when they get older, your mileage may vary. IRC tires seemed to be slightly softer than dunlop, maybe grippy-er? but my knowledge of that is from at least 4 years back, since then I have been using michelins.

    Michelins are high$$, but what isnt? I bought cheaper tires for the family truxter, they ride like SH** smells, rough like an old wooden wagon, IMHO. Now I know, I should have just bough the same michelins I wore off of it, now I know.

    I like to add a bit of dish sope to some water and rub it round the tire and rim where they meet just before inflation, seems to help make the bead set a bit nicer.

    Just my exp. Good luck!

    I have one of those air blower attachments for my compressor. If you remove the tip it will thread onto the valve stem. With the valve core removed you get the full flow of the compressor. The bead will pop instantly with that much air folw. Super easy...

    Should I replace the rim sealing strip. Original is vintage 2007 and valve core won't come out due to previous owners Slime use. I would like to have to do this only once!!!

    If it doesn't leak don't disturb it. If it leaks the rim may be corroded and a new seal won't help.

    It's been my experience that single track dirt bike guys love 'em due to hard compound (last longer under higher horsepower) but trials guys usually stick with the Michelin or Dunlops.

    I fitted a couple of these tyres several months ago and because my rims are old and battered ('90 Fantic 307) fitted them with tubes in. They are a definite improvement on the very old and worn (rounded) Dunlops they replaced, but can't help feeling the Dunlops were more "compliant" and grippy on dry rock, and it's only the newness of the fresh square knobs on Pirellis making them seem better on grass and over logs.
    A fellow rider commented on the lack of grip my tyres were (not) displaying at the weekends club event, as I struggled on almost every (dry clean rocky) section and I have a feeling he was perplexed as to how I could make sections so fundamental for them, look so goddamn difficult for myself ! but I also think he may have been trying to be kind to me by looking for any reason apart from my lack of ability.
    Running the rear right down at 2psi still had it feeling quite hard in the side wall compared to others' obviously softer tyres (sorry, dont know what they were rolling).

    I wouldn't expect the stiffer side walls on a DOT approved MT43 to give as much grip on a light trials bike as they would enduro or dual sport. They just wouldn't flex as much with such low weight, wouldn't conform to the ground surface right.

    Just my 2 cents.

    I've run the Pirelli's on my dirt bikes off and on over the last 5 or 6 years. They are a good option on a TRAIL bike, especially in rocky conditions. They hold up better than the Dunlops or Michelin's and you can ride on them flat, if you have too.

    Conversely, I think they suck on a real trials bike. I'll stick to Dunlops or Michelin's.

    On the same subject of rear tires. Can anyone tell me the difference or compare the Michelin Competition Radial and the Michelin X Light Radial tire, other than the latter weighs a pound less. Has anyone here used both or either and have an opinion?
    Thanks

    It is not exactly what you wanted but I use the X lights. before that I use the Dunlops and I R C's. I guess I'm not sure what you're asking I don't know I would pay full price for a Michelin regular radio when I can buy a Dunlop or IRC for 2 thirds price?

    And competition I really like the X lights. But I do say, they wear funny. I think the rubber they save is right below the Nobbies? When my ex lights start leaking around the Nobbies that's when I buy a new tire about once a year.

    I was thinking jonnyc21 was talking about the regular Michelin, not the X Light. So I was wondering if anyone had tried both. I also see that Michelin makes a tubetype tire for the older rims. I'm assuming they are the same other than the bead area.
