Another gosh darn tire question
I have a Cannondale CaadX with 700X35 Sammy slicks on it. Factory tires. I do 99.9% paved road riding, I more or less use it as a road bike, but I am a big guy so a traditional road bike wheel set I didn't want to build....ANYWAYS the tires on the bike I am tearing up pretty quickly. I am going to change them out this winter to a more road type tire for better wear. Would I gain any thing by going to a 32 or even maybe a 28 tire?
thanks,
thanks,

A less comfortable ride and higher chance for pinch flats in exchange for a marginal improvement in aerodynamic profile.

I would imagine that with the same weight distributed over a smaller area smaller tires will get "torn up" more quickly. Are they sufficiently inflated?

Assuming other things being equal, you'd get less wear with a skinnier tire.

the slick , one assumes, uses a softer rubber compound , (go-fast cornering grip)
there are harder rubber compounds in some more utilitarian tires
I used a Suomi Nokian (Finnish) A 10 , and the tread wear is very Long.. same rubber as used in their other, studded, tires.

700x35 is a big tire for road riding. You might try 32mm if you are 300lbs or less. I've been riding the Michelin Pilot Sport (in 35mm) and they wear quite well. Consult a tire pressure chart before making your decision. Here is a handy calculator and chart. Problem Solvers | Optimal Bike Tire Pressure

first thanks all. The tires I have now are wearing fast because they are gravel type tires and I am using them on pavement just not made for that and I am larger. That is why I need a more road type tire. According the chart below my pressure is good. So I don't think its an issue. I just think its tire selection. Just not sure if the 3mm difference in the two tires will make a noticeable difference.

I'd just assumed a "Sammy slicks" was a slick.
A "real" slick should wear MUCH longer.
A "big guy" doesn't tell us anything about how much you weigh, which is a BIG factor on desired tire size.

28mm is generally where really light tires with high thread count casings start.
They won't be as tough as the stock tires but will likely ride a little more nicely due to more supple casing.
If you get 28mm with 30 tpi then probably gonna feel about the same or worse than current tires.

I'll confess my weight is going up, but I'm still about 30 lbs below you. I no longer ride 23's, but still trust 25's at my weight, so I'd think a 700x28 should hold you - assuming your rims aren't too wide or narrow, if that's possible. There are a number of well made tires in that size.

Soma New Express C line, 28, 32, or 35mm. Get the black, they'll last longer. Light, supple, tough sidewalls, smooth-riding

These are my favorite bang-for-buck 28s at the moment.

I weigh 250.
622-25mm on my hybrid and 559-32 on my "grocery getter" MB. (Sometimes it has 50+ lbs. in the rear baskets.
If you have SMOOTH pavement, 28's would be great. Rough textured, go to 32 and if a lot of potholes, 35.
That assumes your current 35's handle everything OK.

At 295lbs, assuming a 55%/45% weight distribution, on 28mm tires, you'll need 122psi in the rear tire. With a 32mm tire, 98psi. With a 35mm tire, 84psi. I'd go 32mm minimum.

OK so I am going to stay with the 35.....I have talked to many people here and locally and they all said the same thing you are not gaining enough to drop to a 32 from a 35 that I would really know the difference. All said buy a high quality tire and ride on.
thanks all. Kojaks look super!!

If the Kojaks are too pricey, Specialized makes a nice 35mm slick. 100% bald too, like the Kojak. It's a little heavier, but it's a nice tire.
