It now has 21,300 miles with No Flats

Here he is 8/5/11.

The rear tire on the Green bike.

I'm stressing about the weight of the 700x28 Marathon Plus tires in my cart at almost 2 pounds apiece...

I agree with Lex that the rider's weight shouldn't be a concern. The load will influence ideal inflation pressure, but I haven't heard of any tires with weight limits or any that are particularly well suited for heavier riders.

Generally a tire designed for touring will be more durable than one designed for racing.

I guess I need Schwalbe Marathon Supremes, but can't find a source. Schwalbe is sold out of 28s.

All I see is blue.

What size is that?

Is it a road tire or more of an all terrain design?

Why do you have only one of them? What's on the front?

There're bikes in the picture?

That looks to me like it is the front.

Agree, but I'm pretty sure the poster was referring to HIS weight...not the weight of the tire...

Lexi01, You are right that the poster was referring to HIS weight. I was attempting to add another point of view in response to your post earlier in the thread:
The reason for my post was because some people were recommending Schwalbe Marathon Plus tires, which are heavy enough to cause some cyclists to think they make a bike sluggish. They are notably heavier than most tires, so the tradeoff to get the durability of the Marathon Plus is that the tire is quite a bit heavier than most other tires. Marathon Plus tires can be as much as twice as heavy as the Marathon Supreme or the Racing Ralphs, depending on size. Since Marathon Plus tires can weigh as much as two pounds, they can take more work to spin up to speed than the Marathon Supreme, or most other tires mentioned in this thread.

I wasn't trying to make anything more difficult for the OP, so I hope my earlier response didn't cause any confusion for the OP.

I found this chart that recommends tire size and inflation pressure based on weight and terrain.

I appreciate your post, Scooby, and I had noticed the weight (of the tires) and was stressing about it before you posted. Unfortunately the 28c Supremes seem to be sold out.

Because of my experience I don't want to purchase Vittoria. Sorry I don't know which model I had. I tried to find out from Bikepedia, but it seems my bike was supposed to come with Hutchinson tires.

In the meantime, the vendor I was planning to buy the Marathon Plus from has sold out of all 700c sizes.

I have Rivendell Roly Poly tires on one of my bikes. 250 mile so far including about 50 off road without a single flat! Haha, I don't ride that bike much...

I'm think about getting the Rivendell Ruffy Tuffy which is the Roly Poly with thicker rubber and a kevlar belt.

Qmsdc15, it sounds like you have good reasoning for what tires to get. I don't blame you for staying away from the Vittoria brand after your experience. It's a shame you can't get the 28c Supremes right now, as they would be ideal for what you need. If there was a local shop in my area selling Schwalbe tires, I am confident they would sell well. As it stands, not only does one usually have to order the tires, but they are frequently out of stock in the size one needs. That's what happened to me when I needed a set of 26x1.6 Supremes.
