Swapping tires?(4 posts)

Swapping tires?Strom
May 2, 2001 7:57 AM
I'm looking for a bike to use in commuting about 10 miles each way over pavement, and I'm considering the Specialized Sirrus Sport, the Trek 7500FX and 7600FX, and the Jamis Coda. I test rode the Coda yesterday and liked it alot, but I'd like a bit faster a ride if possible (my path is fairly smooth). It has 700x38 tires on it, and the Treks have 700x35 tires. Before I decide which one to buy, I'd like to know how feasible it would be to put narrower tires on the Jamis or Trek bikes (the Sirrus has 700x26 tires). How narrow would I be able to go? 32? 30? Is this a good idea?

I read an article in "Bicycling" where the paricular editor felt thet the advantages of narrower tires were very limited. You'll also run a higher risk of flats due to pinch flats. I think it's worth the extra comfort of wider tires. I'd run 28's at the narrowest.
Agree w/celloboy about 28s, but if you WANT to...Retro

...you could certainly go down to 23s or even 20s. Bike tires are almost infinitely interchangeable within a given diameter. I've had everything from 20s to 38s on my commuter with no problems ever.
But he's right--anything smaller than about 28 is just asking for a harsh ride, pothole damage and not going any faster despite that.
So going down to as low as 28s would be ok?Strom

Would I notice the speed improvement and still be in good shape for city/suburban riding (mostly bike paths)?

Thanks for the replies!
