New tire report

A week or two ago I asked a question about tire weight, rolling resistance, and puncture protection. The post received a great deal of attention, and, as expected, lots of personal opinions as well as experiences. Since then I bought and installed 32mm Schwalbe Marathon tires on my Domane sl5 disc endurance bike. Some good weather today allowed me to get in a 20 mile ride, my usual distance. This is what I discovered. The tires were twice the weight of the the ones I replaced, Bontragers that came with the bike. The bike did, in fact, feel heavier when I picked it up. The bike did feel a bit sluggish, especially when I applied pedal power quickly or when I started up a hill. I didn't feel any increased harshness in the ride due to the stiff sidewalls of this tire, nor did I feel any squishiness due to lower tire pressure. I rode them at 60 psi, and I weigh around 163lbs. It was difficult to determine these differences because the last time I rode the bike was about ten days ago and its hard to remember what the bike felt like. Nevertheless, I truly believe that I noticed these differences. I did seem to expend a little more energy than usual to keep up to my customary speeds and hill climbing. Overall, I like the tires. If they prove to be extremely puncture resistant as I expect, then the tradeoffs are OK with me. I am not a racer or even a fast rider. Thanks for all the information and suggestions. If my opinion changes over the winter, I'll report back.

Are they the Marathon Plus HS 440, the Marathon HS 420 or some other variety?

Just plain Schwalbe Marathon. It has the Green Gurard protective belt, but the tire simply says Marathon.

OK, thanks. So it's these ...
https://www.schwalbetires.com/bike_t...s/marathon_420

I'm not surprised the bike feels a bit heavier as they have a good deal of flat protection built in.

I know someone that has a set of Marathon Plus in 700x28C with low miles. I was going to make them an offer, but after seeing they are 750g each for 28 wide tires I'm going to pass.

Thanks for the write-up.

There are two types of puncture protection. A Ďbreaker beltí and extra layers of rubber underneath the treading. Some tires combine both. These two types, stop two different types of punctures. What makes a tire heavy and feel sluggish, is weight, of course. So if you add extra material as a way of stopping certain kinds of punctures, you add rotational weight. This is what your chosen tires employ. Your desire to offer up your opinion alerts my common sense meter that this added weight and sluggishness bothers you. You are weighing this against wether it proves worthwhile. This is fair enough, but short of actually running over a nail, screw or either piercing type piece of road debris, how will you quantify the tires worth, when this will be a completely random and most likely, a rare experience? In other words, proving their worth will likely be a once only situation, where every single other day, youíre pushing those heavy tires, for essentially no justifiable reason. Will that one or maybe two experiences, where you didnít have to stop and immediately change a flat, be worth all the days you had to push those heavy tires? Maybe so, but Iím willing to bet itís a constant tough sell. My guess, is that over time, as you ride more, you will find yourself wanting lighter weight tires. I could be wrong on that of course. All in all, I wish you happy riding on your new tires.

If your SL5 had the Bontrager R2s like my Domane SL6 came with, the added 2 lbs of tire weight across the two is probably noticeably at your weight plus low bike weight. The tread is also going to make a rolling resistance difference that is noticeable.

But on my steel touring bike (Trek 520) and my weight (230lbs) going from cheap treaded tires to Schwalbe Marathons had no noticeable riding difference. Probably only a 1 lb difference in the rotating weight, didn't feel much different to me - and the Schwalbe's are lasting forever.

if you don't ride with other people to slow down, or up hills the tires will fit your needs, if the tire is pneumatic no tire is puncture proof, though. tire and rim weight will make a huge difference in acceleration and hill climbing due to the physics of rotational mass not so much overall weight added to bike. heavy tires will make hill climbing burdensome as well as riding into headwinds. I have a touring bike with Marathon HS 469 tubeless tires in 35c that seem to be lasting forever. they have only had one puncture (drywall screw in through tread and out through sidewall) which tubeless sealant almost sealed both holes. installed tube and finished ride.

I've been running Schwalbe Marathon Plus 37s (38s?) on my daily commuter for three years. Not only have I not experienced a single flat, but the tread shows no signs of wear. Reflective sidewall stripes are a bonus.

It the bike a bit more sluggish? Who knows? Not having to change flat(s) in freezing rain? Priceless...

I have the same 2018 Trek Domane SL5 disk, which came with Bontrager R1 32 mm tires. They wore quickly and I replaced them with Bontrager R3 32 mm's. Although a step up in quality, they were not significantly different from the R1's and began to ware just as quickly. I replaced them with less than a thousand miles (not because they were wore out) with a set of Continental 4000S II 28 mm. The Conti 28 mm tires measure 30 mm on the rim. I couldn't be happier. I like having a not so wide tire as the 32mm, they are faster and feel much more lively. With 700 miles on them, they show no signs of ware at all. When they begin to ware out, I look forward to replacing them with the new Conti 5000S which are soon to be released. New for the 5000 series, 32mm's, but Conti's have a habit of measuring wider on the rim so that's a bridge that will have to be crossed. I personally like a slightly narrower tire on the Domane for on road use.

I've replaced the stock tyres with Schwalbe Marathon Plus's on my Brompton. I'm hoping that they'll prove much more durable than the Brompton tyre, which looks like a Marathon but clearly isn't and hasn't proved to be that good. The main difference I notice is that the ride quality is extremely harsh by comparison - exacerbated by the 16" wheels, no doubt. Brompton insist on the tyres being pumped up to 100 psi whenever they leave a workshop so I have duplicated that but I think I shall be running them at a slightly lower pressure to try and calm them down a bit. It isn't helped by the fact that some of the roads between home and my local train station being of truly appalling quality. On the plus side, I was very surprised to find that they feel a little quicker than the Brompton tyres - although that's purely a subjective judgement.

I think that you are right, but seeing that I already own the tires and that they are on the bike and that it is now winter, I think I'll leave them on for a while. I have a touring bike that I can put them on when the tires that are on that bike wear out.
