    Tyre help please.

    Hi to all, I am new to cycling and have purchased a Trek 8.5 DS.
    I want to do a bit of off road, but one guy has told me that i might buckle the wheels on the current setup ! and would need to put bigger tyre's on before going off road.
    The bike is fitted with Bontrager AT 650 rims, can anyone please tell me what is the biggest tyre that will fit the rims.
    Normal tyre is a Bontrager LT3 700x38c.

    It's not about the rims. It's about clearance in the frame. When this came up for my girlfriend (now wife, so it wasn't too much of a disaster!) and me, I bought some nominal 29x2.1" tires for her, with a lowish tread pattern. I bought Bontragers so that I could return them if they didn't fit.

    Take the bike to the shop with you and tell them you want the biggest, knobbiest tires you can fit.

    Hybrids aren't ideal for off-road, but the tires are really the single biggest problem. So this can be a good way for you to get a taste and see if it's something you want to pursue without having to spend another few hundred dollars.
