28c too big for training?(4 posts)

28c too big for training?bm
Oct 20, 2002 11:21 PM
was wearing down my stock racing tires, so finally bought pair of 700x28c. i was looking for 25s but this is all the LBS had.

my question is, are 28c too big? . . . because they look funny on my rims.

what are the advantages of bigger training tires, besides additional weight and puncture resistance?

are there any disadvantages?

thanks
Comfort. Lower pressure allows less frequent inflation. nmdzrider

And swear by them. Heavy, stiff, sluggish...just the thing for a winter in New England. Add to that the fact that it will take a hammer and a nail to puncture them (Armaddillos) and they are just the ticket to ward off cold fingers (not much fine changing the Nth flat on a long, winter ride with those rumbling beneath me).

Disadvantages - heavy, stiff, sluggish, high rolling resistance, look kinda goofy

Advantages - burly, bombproof, good traction, and quite comfortable.

My advice is to get the largest tires you can run and fit a) between your chainstays b) under your fender. You won't regret it.

You could argue that for training, bigger is always betterSilverback

There are studies out there that show big tires have no greater rolling resistance than skinny ones pumped to the same pressure. Certainly my times on 32mm tires vs. 23s don't show any consistent difference (I weigh 225, and I've experimented with bigger tires for a better ride and longer life). I do fall off a bit with 35s, but I run those at 75-80 psi.
All that aside, though, if you DO have to do more work with bigger tires, isn't that an advantage in training, not a drawback? At least when you're laying down your base miles and doing the basic aerobic groundwork, there's no benefit to making it easier.
