    another tire question

    I'm sure this is a dumb question but I was messing with my commuter today and noticed that the back tire appears more warn then the front. its a rigid which I would have thought it would be about even in terms of tire wear. I know I occasionally "lift" the front tire for driveways and such but I doubt that would account for such a difference and I don't really lock up the back tire enough to cause "excessive" wear and I keep the tires pretty close to if not the the same psi so it shouldn't be a difference in psi issue. it also appears to have the oe tires on it but not sure as I got it used

    any ideas on what might be going on?

    My guess would be that, because it is the drive wheel and thus there is more driving force on it, that would be the reason for the wear. I wouldn't think it would make as much of a difference on a bike as it would on a motorcycle, but who knows? Do you know how old the tire is? Is it kind of a soft compound?

    There's more weight on the rear tire. If you rode around on your handlebars everywhere you went, you'd wear out the front first.

    (unless you don't have studded tires)
    (no excuse for that either)

    Oh wow, that makes sense! Sort of a like a lever? Even though you don't usually sit directly over the rear wheel, the front wheel acts as a pivot point to distribute most of the weight over the back wheel. Guess that also explains why my back tire appears to have a flat spot while I'm on the bike. Now I see why there are whole branches of science dedicated to the study of the physics of bikes and motorcycles!

    yep, most of your weight sits on the back tire, witch creates more wear...

    WHOA WHOA WHOA!!!!!

    More weight has a minimal effect on tire wear -- THE BACK WEARS FASTER BECAUSE IT IS THE DRIVE TIRE! PERIOD!

    no, you are wrong, sorry bigpedaler

    it would only affect it if you skid alot, but he said he doesent. its purely a weight issue

    Couldn't both be a factor?

    I gotta disagree. Ask any truck driver if trailer tires wear out faster when the trailer is empty or full...

    I'm sure both could be a factor if one were to lock up or slide the back tire quite a bit as well as weight. but seeing that I don't lock up or slide my back tire real often I gotta lean toward weight in my case espec. since I am a bit over weight
