Anyone on 30mm road tires? How do you like them?
 

Looking to pick up either 30mm Continental GP5000s, or 30mm Vittoria Corsa 2.0s.

Anyone here riding 30mm or 32mm road tires? If so, what are you riding?

Currently on 28mm Panaracer Gravel Kings (which are nice), but do want to increase my tire width a bit more.

Thanks!

I've got a pair. G+ or 2.0. I'll stay on the G+ 28s on the Mooney now until the road conditions change but those 30s look like they will be perfect for the lousy winter roads.

I've got Continental GP5000 TLs in 32mm on my gravel / commute / allroad / etc bike. Normally ride Continental GP5000 in 25mm on the road bike.

In comparison, the 32mm tires are really nicer in the wet; they do feel like they've got more grip in general, too. They're better for the worst bits of asphalt or offroad (which they do well enough, in my book). On the road they're faster than the gravel tires I rode before on that bike (like, "I don't need to analyze data" faster, it's obvious just from the average speed on my commute), but my race bike with 25s is faster when pushed on a nice road. Some of the difference is the bike, naturally, and I haven't done proper aero testing yet, but what data I can find suggests there's only a couple of watts in it at 35 km/hr. It's also 100 grams extra.

I like them, but I like 25mm tires, too - when you're going on the nice road, the sun is shining, and you're flying, who wants a big fat tire?

It's one of those situations where N+1 is the right answer.

I'm riding Pirelli P- zero 30mm tubeless on 23mm internal width hookless rims with 52/56 psi. Works great. I also have 28mm Michelin tubeless on 25mm internal width hookless rims using the same pressure. I'm sold on hookless.

With 23mm IW rims, the 30mm tires measure 32mm and my 28 tires on 25mm IW rims measure 31mm.

Tires are expensive. Do you really want to spend that money for 2 mm ?. I could see maybe going to 36 or something.

I've used Continental Grand Prix tires 28c for several years now, typically at higher pressures. I've only recently started lowering the PSI and using wider versions. 32cs at low pressure are working well. Compared to narrower versions of the same tire, it's more comfortable, a little more secure on dirt roads and light gravel, and doesn't incur any performance losses.

I wouldn't bother with 30c.

Schwalbe pro-one in 30.. my winter road/light gravel setup. I like them plenty.

I ran the 30 GP’s on my endurance bike for quite a few miles and liked them a great deal. I switched (back) to 32’s as they are easier to find but wouldn’t hesitate to use them in the future.

I'm riding 30mm Vittoria Zaffiro Pro V and am very satisfied with them. These are the tires that came on my Caledonia when I bought it and I haven't changed them.

After enjoying some 28s on a couple road bikes where they would fit I put Vittoria Rubino Pro G2.0 on a Habanero Ti frame and am very happy, My arthritis lets me know where if an improvement came about..

My 2022 Canyon Endurace came with 30 mm GP5000S TR and I ran them all season, including the L'Etape du Tour. No complaints, super comfortable and they seem fast enough. I think a lot depends on your rim width too. My DT Swiss rims are 22 mm internal, which I think goes well with 30 mm tyres. I've previously run 32 mm tyres on 17 mm rims and they looked a bit bulb shaped.

I run the Pirelli P Zero Race TLR's on my Domane and love them. At one point I moved to the 28's, but I found I liked the 30's better.

I use Bontrager R1 30c slicks on one of my cyclocross bikes for winter road training. I like them a lot.

I have both Zaffiro Pro and Rubino Pro, 30mm tires on bikes. The Rubino's are a much smoother ride with less weight, but the Zaffiro's were bought on-sale at $15. That is pretty hard to beat for a decent tire. Both the latest models of those tires.

I'm riding Schwable Pro 0ne 28cc tubeless on my road bike inflated to 65 psi. They seem great. Much nicer ride than Gp 4000 25cc all season tubed tires inflated to 80 psi on my alloy road bike.

My question to you would be: why do you want to increase your tire width by a couple of mm? All other things equal, that's not a big difference.

I've run various (really good) 28s and 30s and the 28 vs 30 part is often the least concern. The same nominal size tires, from different manufacturers, often measure out differently; unless they publish WAM/RAM specs, it's hard to say what the actual size differences will be. More importantly, the casing construction and compounds used will often overshadow any theoretical, all-other-things-equal differences brought about by the actual volume change.

Because of this, my advice would be to focus on and try out tires with a reputation for excellence in whatever quality that you're looking for - suppleness, grip, rolling resistance, etc - rather than going to 30mm for the sake of going to 30mm. Really though, it's all going to come down to trying things out for yourself and going from there. It's highly unlikely that you'll buy a tire, in the realm that you're talking about, and think that it's so bad that you wouldn't ride the tread off of 'em, so just start trying 'em. Once you find a tire that you really love, consider fine-tuning with small size change up or down, within the same make/model, if desired.

I had been running GP5000 in 28 on my Emonda because that was supposedly the max that would fit. Had to replace because of wear and a tear and noticed Trek had upped the max for the frame to 30 so I went with that. An improvement but not worth swapping out good tires for

If your current tires are wearing out and one or both is ready to replace, then why not just try them out. You'll be the only one that can tell if they do anything for you. Or if even your tires aren't worn out but you are just curious.

It's not like your choice is permanent and you can't replace them if you don't like them.

Why not just go with 32mm GK slicks, then?

I've been happy with mine, although I'm merely a recreational rider with no illusions of looking like a pro or being fast.

I have been running 30mm for several years now .. first some Specialized S-Works Turbo and now GP5000 S TR. Its not worth going up 2mm if your old tires are not worn out, but when my old 28s wore out a few years ago I got 30s and definitely appreciated the touch of extra comfort and grip.

When the Turbos wore out I thought about getting 32s but decided to just stick with 30s.

Note that todays 30 is the same as a 28 from several years ago - tire companies shifted their sizing since the average rim got wider which fattened how tires sit. If you are on fresh 28s those are like 25s from the past. Another reason to bump up the size a bit perhaps.

My 700x28 Gravelkings measure 30.5 on Pacenti rims that are around 18mm on the inside. Depending on which 30mm tire you buy you might not actually gain anything.

Depending on rim width a 28mm GP5000 will end up a little over 30mm. Like a 23mm rim. :rolleyes:

I used to go for 23mm tires, because I didn’t know better. Now I use 28 on all my road/commuters. I would probably use wider if I could fit them.
