Running 35 T-Servs right now. Love em'.

Last tires were Randos. Never buying them again. Aside from riding like poo the rear developed a nasty sidewall split after like 6 months.

I use 700x32 Panaracer Pasela Tourguards. Good tires, good price. Only one flat all year.

Riv Panasonic Jack Brown , are light, supple , probably fast, under someone that wants to put the work
into the pedaling.

they did make me think A Cyclo-cross Bike* is good enough as a road bike.. if not actually racing..

* ['90, Steel, Pinarello made]

There are even more expensive handmade tires sold..

I wish I would have known the Randos were so slow before getting them. I just put on 23mm Gatorskins from my other bike to feel the speed again. Obviously, dropping from 32mm to 23mm make a difference but the Randos are just plain heavy...

The T-Servs seem to be the ticket with the high PSI and much lower weight then the Randos.

Another vote for Panaracer T-Servs....32's or even 35's........also Panaracer Urban Max.......similar tire, much cheaper. I think I have gone through about 5-6 of these tires. Light, fast, puncture resistant, and good on many different surfaces and conditions.

Didn't care for the Rando's..........harsher, slower, and sidewalls cracked in about 1 1/2 - 2 years.

Well, since this thread is over two years old, I have tried some other tires. I'm currently running Vittoria Randonneur Hypers on my touring bike and they roll very nice. They are relatively light (350g) for a 32 mm tire, but are noticeably heavier than 25-28 mm folding tires. On my main commuter bikes, I use 25 mm Vittoria Rubinos and Continental Gatorskins but the roads are pretty good on my route. Plus, my route is very hilly so weight is more important to me than width. The Rubinos are some of the nicest rolling tires I have used and reasonably durable.

Only have experience with 700x32 Vittoria Randonneur Hyper reflex vs GP 4000S. I put the Hypers on because they gave me a more comfortable ride than the continentals and I didn't really notice the speed difference on smooth asphalt. I did notice a big speed difference on unevenly paved roads, where I had to slow down with the continentals but could just motor through with the hypers. So far I've been very content with them and only have had 1 flat in about 3000 km (small sharktooth shaped stone puncture) on a rainy day. Great summer tyre imo, and I bought a second pair on discount for 15 Euro

Everyone sees that this is a zombie thread, right?

That said, I recently switched from 700x28 Conti GP 4 Seasons to 700x35 Schwalbe Marathon Supremes. My average speed has been down about 1-2 mph, and there are conditions in which the Marathon Supremes feel very heavy -- which makes some sense since they are twice the weight of the GP 4 seasons before you even factor in the bigger tube. That said, I'm pretty happy with the Marathon Supremes. They roll extremely well once you have 'em spun up. They have excellent grip, even on wet roads. They have a reflective strip on the sidewall. And, of course, they provide a lot more cushion than the skinnier GP 4 Seasons.

The only factors yet to be determined (for me) are puncture protection and durability. The GP 4 Seasons had fantastic puncture protection for the conditions I ride in (well paved bike lanes with lots of road debris), and went over 2000 miles before they wore out. I've only got ~250 miles on the Marathon Supremes, but they've been problem free. I previously used 700x50 Marathon Supremes for 1500 miles, after which they looked like new and had only punctured once, and that from a wood screw buried into the tread.

I noticed a lot of people hating on the Vittoria Randonneur. Wondering if anyone has some experience with the Randonneur Pro? Seems like it's lighter and has a much higher TPI (120 vs. 30).

Me thinks you simply add a bit of (good) perspective I know the thread is two years old, but it is still relevant. Funny that most of these threads, whether two months old or two years appear to be relevant (except for the price of things).

A little late for the OP, but for those that are reading I love the Schwalbe Marathon Supremes on my Vaya (700x40). I think they will be the last tire I'll ever buy (that's what some of the older people I know say when they buy a new car at about 70 years of age)! Just kidding, but they do appear to have no wear after about 2,000 miles - and nary a flat. Fast once you get them up to speed and very smooth and comfortable riding.

I havent tried all the tires listed. I have Panaracer Pasela tourguard in 32mm and T-serve in 28mm. I like both and wouldnt call them fast tires but not so slow either. I find the 28mm Tserve to work well for my general riding, feel it is a good compromise of thickness and durability. The 2 tire models are very similar but Tserve feels a little sportier to me but hard to compare since diff widths.
I have 38mm Schwab Marathon Plus on a hybrid bike and i call those slow.
