Tire width for newbie question(6 posts)

Tire width for newbie questionAndy Dufraine
Jan 11, 2002 3:16 PM
Time to replace the michelin Axial pro tdf's that came on my bike (used). I'm looking at the michelin hi-lites in red/black cause the would look sweet on my red and black GT ZR2000. But they come in 20 and 23 and I don't know which would be better. I'm 6'4 225. Does this mean 23 would be better as I'm much bigger than the average rider? Or will 20 at 110 psi be just fine??

ps. RIP Brooksie

I'm 5' 7", 135 lbs, and I wouldn't ride anything narrower than 23's! I'd say you should stay off of the 20's. 23's might be a bit rough due to the higher pressure but not out ot the question for you.

Read the "23 vs 25" thread earlier today for more viewpoints:

You should be on 23s, 25s or maybe even 28s. The size of your two tire's combined contact patches on the road is the bike+rider weight divided by tire pressure. A skinny tire will have to deform way too much under the 245 lb load to give you a good ride. A larger tire will have a lower pressure rating, and therefore a larger contact patch, but won't have to deform nearly as much. As a result, you'll have a better ride (rolling resistance probably about the same) and better traction. Less chance of pinch flats too.

I would say try them both....everyone can give you all the advice in the world on what is "supposed" to be the best for you but you'll never know if you dont try them both...I am a little bigger than you (6`4`` 240lbs) and I was always using at least 23s...I decided to try out 20s and I loved they way they I wont use anything else when I race...My training tires are 23s...but i definatley like the feel of the 20s....the only way to know what will work best for you is to try them....but you cant go wrong with the 23s
stay stoked

The Michelin Hi-Lites are great tires. I can't tell any difference performance-wise between them and the Axial Pros, and I think they will wear longer. At your size (or just about any size), I would definitely go with the 23s. They used to put 20s on nearly all road bikes years ago, and I couldn't believe how much more comfortable riding 23s were when I finally got a set. They also are less prone to pinch flats. The only reason to use 20s is if you're racing, and even then it's doubtful that it would provide any advantage. Bicycling mag had a short article on rolling resistance in tires within the past couple years, and the conclusion was that wider tires (up to a point) actually had LESS rolling resistance than the real narrow ones. And there is no doubt that the wider tires are more comfortable.
I'm your size, and I don't even own anything under 28 anymorecory

I've been down as far as 20s, but there are just too many drawbacks (stability, comfort, tire life) to skinny tires. I run 35mm Paselas on my Atlantis, and either 28s or 32s on my Allez and Trek (I'm not bragging; they're OOOOLD). The 35s might slow me down a little (less than a minute on my 12-mile ride to work), but the 28s and 32s not at all. Most tires marked 32 are only 24-26mm wide anyway.
