    So yesterday I decided to do a fresh experiment regarding the rear tire on my '17 Factory 250, which came with the best trials tires, the Michelin so called Lite tires.

    My rear was rounded in one direction, so should I turn it around or fit the Dunlop 803GP languishing all year in the corner of the shop? I decided on the latter. The reason? The stupid Michelin rear is $180 from my cheapest source!!

    I weighed both tires. The new Dunlop is 12.3 pounds, and the used Michelin is heavier at 12.5 pounds. So much for marketing BS.

    The profile is more rounded on the Michelin uninflated, but that seems to reverse when inflated.

    The carcass is way more flexible on the Michelin, especially at the intersection between the sidewall and outer knobbies. How much of that is broken in versus new?

    First test ride I used 4.0 psi in the Dunlop instead of my usual 4.5 psi in the X-Lite. The rear still felt a little butt high with the Dunlop, and traction on the new Dunlop would break break earlier than the used, rounded Michelin. I know I will have to run the Dunlop at lower pressure, at 3-1/2 psi or even 3.0 psi for equivalent squat and improved traction.

    Going this weekend to compete. That should break in the new tire carcass. Just hope the tire doesn't cost me the potential for a win! In the last two events, the spread between first and second overall was 0 and 2 points!! It'd bad to end up 2nd place - if I'm able to ride sharp - from one rear tire slip :-0

    If I get the Dunlop 803GP to work fine, great! I'd rather not reward Michelin's effort to extinct itself with ridiculous pricing in the aftermarket.

    I never liked the X-Lite. The sidewall is way too soft. The X11 I like a lot, but of course you can't really get them here.

    Run the 803GP at 3.5psi. It'll still feel a little tall, but it starts working really well once it's a little worn in. In fact, I think it's stickier than the X11, but it doesn't last as long.

    Take plenty of slime as I had a leaking issue at the Texas National with the Dunlop. I should of been going this weekend, but setting a vintage event instead.

    Curious as to what you find, Chris. My '18 (non-Factory) 250 came with Dunlop tires. I've always run 4 psi, in the rear, but am still too much of a noob to feel any difference (with pressure settings or different tire makes).

    X-Lite, the tire is not perfect but very good on every ground. With other tires there's
    exceptions and slippery roots is defently a speciality of the X-Lite, probably because the tire has so soft flanks.

    The majority of top riders in the World Championship use Michelin X 11. Sadly only the X Lite is available in the US. The X Lite is used very little in the WTC.

    I have tried to convince Michelin to bring in the X 11 rather than the X Lite but they would not listen.

    Dunlop rules the US market due to price, availability and involvement in the sport. Kudos to them.

    6 oz. Quadboss sealer was dumped into the tire before I popped on the last bead side.

    Early version of X-Lite was more puncture prone in sidewalls. Maybe that bad reputation is why world teams prefer X11? A stuck risk reduction policy? Based on current durability with the world's best?

    The new 2018 Beta Factory bike's are coming with X11's. Last years came with X Lite's, I prefer the X Lite. Good luck Chris in this weekend's Trials event, my son and I are competing for this Sunday's event ( SCTA ) Lucerne Valley, in the desert. Riding the 2017 bike as I'm not finished prepping the 18 Factory.

    I preferred the X11 that came with 16 Evo 300 over D803GP (or X-Light) but the D803GP seems to work pretty well with lower pressure (3.5 to 4 psi). I typically reverse direction when the leading edge rounds off. My practice wheel has very worn knobs on X11 tire, but still has amazing grip for the condition it's in.

    For fun, I rode over an hour in 6" of snow with worn X11 and practiced going as slow as possible to sharpen my balance and clutch skills. Tried to plug puncture of sidewall in D803GP with minimal usage and previous ride ended with flat tire back to van. Got Quadboss sealant to try, once I reverse direction to get sharp leading edge remounted. $300/set of Michelin tires is way more expensive than D803GP tires. If Michelin would bring the X11 to the States for a reasonable price; they could easily outsell the Dunlops.

    My '18 Scorpa Factory came with X11 instead of last year's X-Lites and I was happy with that. I'm a little ham fisted going into edges sometimes and was afraid of punctures with X-Lites.

    Tryals Shop usually recommends IRC for lighter riders and Dunlop for heavier riders.

    I am just looking at the pictures and thinking I need to get off my butt and replace the rear tire on my 07 Montesa, its way more rounded than yours... :confused

    In the end however I should consider Norman's comment and maybe put some IRC's on it (or X Lite's) as its now being used by my daughter and she sure wouldn't be classed as a heavy rider... :lol3

    Lighter riders eh? I'm a skinny 175.

    I should again try the IRC TR011R (just saw $72 on Bike Bandit). Last one I had was like 1/4 century ago, on a TY350 :-0

    I'm parked now overlooking the trials site. Tomorrow I'll drop the pressure to just over 3psi and give the Dunlop a go.
