    Marathon Greenguard and wet grip

    I purchased a single replacement Marathon Greenguard to try as a replacement for my stock 16" CSR tires on my recumbent bike.

    I have not fitted it on yet. The price was good so I went with it after having read a few positive reviews.

    I was doing a little more research on the tire and find that some say it slips quite a bit in the wet.

    On my commute there are many instances where I have to roll over metal plates in construction zones. In wet weather these metal plates get awful slippy.

    I was considering putting this tire on the front, but I am now worried about losing control if it slips.

    Is the Greenguard a dangerous tire to ride with in the wet? Would it be better than the Kojak? (I can relate since I use this tire on my upright).

    I'm quite pleased with marathons (38's) in wet and dry. I really like the 420's but the pluses, not so much.
    I was caught in a downpour in Syracuse with a loaded bike on 420's. The water was nearly up to the bottom bracket and flowing at a good clip. I was not concerned about traction, much more concerned about unseen potholes.

    On the pluses, they wear like iron, great traction and no flats do far... But they're heavy and seem to have high rolling resistance. So they are what they say they are... I pump the plus on rear up to 90 and it rides faster...

    I would expect almost any tire to slip on wet metal grates, paint, etc. I always do my best to avoid them on wet days, even if it means taking the lane briefly. If I have to go over them, I try my best to do so at a reasonable speed, no turning or braking, and being as centered over the bike as possible.

    Hmmm but actually the wet metal road grill situation is not the same as flooded roads or potholes. The contact surfaces are different between these plates and tarmac. There's a sudden change in traction, from nice grippy road tarmac to sudden slipperiness.

    Here's a video of the kind of an accident that I want to avoid (we drive on the left side of the road).

    The tire I've bought is the HS-420 Greenguard.

    The Schwalbe website says that the grip in the wet for the tire I have is 4 out of 5 stars.

    Good advice. I tend to do this also. But it's a terrifying experience. Especially when there's fast traffic approaching from behind you.

    The trouble is that in Singapore where I live we have no practical bicycle lanes, only regular roads and immature laws protecting cyclists. The laws look like they were written by a 5 year old.

    Wet metal is VERY slippery...
    Especially wet metal as a road surface as it will collect oily gunk from the road and tires...

    I've never had a problem with the Marathons I have on my mountain bike. They're just a really good all-around tire, imho. I've never dealt with anything SERIOUSLY wet, but it was raining this morning and they did just fine.
