I have used the Vittoria Corsa G2.0 tire in my long ride for a long time.
However the recent ride, I had several experiences with the flat tire in my recent ride.
When I checked the tire after riding, I could see many stone and glass chips nailed to the tire surface, and removing them was a sort of headache and I was worried about the flat again.
Finally, I purchased the Grand Prix 4-season clincher and it was quite impressive because I haven'
t had a flat tire during my 200km and 300km ride even I rarely saw chips on the tire.
I am not sure about grip on wet surfaces, but I am pretty confident on the dry pavement.
If you are worried about a flat during the long ride, I strongly recommend this tire for you.
Today I had the the rear tire tread split by a sharp rock on a logging road paved with golf ball sized rocks. When I guesstimated the wear on this GP 4, I realized it had close to 4000 miles :) I immediately ordered a replacement of this great tire!
Im a 61 year old recreational cyclist. I ride about 20 miles a day during the week and enjoy rides of up to 60 miles on the weekend. Im not fast, I dont own a heart monitor and I dont use a power meter. I ride simply for the joy of it, so I choose my equipment to maximize that joy. I ride an endurance bike and I prefer tires that are quiet, comfortable and durable rather than fast and delicate. For what do, these tires are perfect. They slot in I rly between the GP5000 (faster, but not as durable) and the Gatorskin (more durable, but less comfortable and slower). I currently have these tires on two road bikes and will shortly put them on two hybrids (range of available sizes is another plus). The only two cautionary notes I have are 1) Conti tires all seem to run at last 1mm large - if your frame clearance is tight, beware of this - and 2) There is a black version of this tire and, while it may be my imagination, I think the black sidewall is stiffer than the natural one. Other than that, great tires!
When the rains start and the roads fill with debris, these tires go on and the GP 5000s come off. I think this tire is a good compromise between the GP 5000s and the Gaterskins in terms of rolling resistance and puncture protection. I've only gotten one puncture in these in over 2 years, although it was a sizable nail that no tire would have survived.
My one gripe with the GP 4-Season is the sizing. I have very tight tolerance with my Ridley Noah and a 25mm tire measures nearly 27mm at 105psi. I can run 25mm with the GP 5000s, but have to run 23mm with these. Very annoying!
The Continental Grand Prix 4-Season tire is my go-to winter tire for the mild winters of California. The GP 5000s come off the bike in January and go back on in April or May. The GP 4-Seasons are not as supple, obviously, but they have good rolling resistance and puncture protection is superb. These tires handle gritty chip/seal roads with winter storm debris, twigs, small branches, small stones, etc., without concern. My BIGGEST complaint by far is the sizing! A 25mm tire actually measures 26.8mm at 7 bar and rubs on my Ridley Noah frame. I have to run a 23mm version on the rear which rides harder.
Balanced and Tough Spin without any wobble adjustment needed. I run 100 - 110 psi - hit potholes and rolled over gravel roads without any cuts or punctures.
Stiff and Grip My average weight is 175lb - have never ran them at the 120 psi max. Feel rock hard at 110 and 100 perfect for commuting and night rides for those sneaky bumps and cracks in the road. The grip to the road is superior, instilling confidence to take turns as fast as you can handle.
Highly recommend these tires and this company - Shipping was fast, (once order was processed) price matching was fast and easy, and the selection, reviews, testing, specs, videos, etc. allow you to research a deep a rabbit hole as you want. Will definitely order from y'all again.
I race on the GP4000SII5000 tires and enjoy the performance to weight ratio of those tires. They hold really well in corners and then during club rides they are super fun to descend on and fare really well against flats when compared to the performance provided. When the race season ended this last season I slapped a pair of these 4 Season 28's on the bike and have really enjoyed them. They can handle gravel and sand, they are almost bomb proof riding on roads with highway bits and pieces of metal, and they can be run at lower pressures to make those long training days a bit easier on the body. Rockysemi-paved trails that will occasionally cut the sidewalls of my GP4000SII's are easily handled with these tires.
The one thing I do have to watch for, however, is the grip when descending. I've come loose in a couple of corners and drifted the back wheel at high speed riding them like the GP4000SII's, which is not the best feeling in the world. Totally my fault for pushing the tires beyond what they were designed to really handle, but I throw that out there as a word of caution to just take it a bit easier when on these tires and pointing the bike through some tight corners at high speed. There is necessarily a small drop off in handling when you are getting the durability built in to these wonderful, purpose built tires. I will definitely buy another pair when my current pair finally give up the ghost.
If you ride on a road with lots of radial wire, glass, and rocks, this is the best tire you can use. great puncture resistance and great sidewall protection, so much better than the 5000 tires that have very weak sidewall protection and wear resistance is also very good
I've yet to get a failure with this tire and I am on my second set. I change my tires roughly every 3,200 miles to be safe but could get substantially more had I wanted to. The 4000s kept getting sidewall failures so I gave up on them. The 4-Season is much more durable and gives an equivalent ride to the 4000s. I was told if durability is your main priority then go with the Gator Skins but if you want solid tires that delivers performance then the 4-Season is the best option. For added protection, I also suggest adding Stans sealant to your tubes and make sure they have removable cores. Careful not to remove the valve cores when taking off the pump nozzle like I did and got 2 ounces of sealant in my face. (Pumps with pressure release buttons will avoid this. )No flats since doing this in over a year and I now ride with peace of mind.
I currently have the Continental GP 4-Season tires in both my bikes (700x25 and 700x28 sized) so you can say I really like them. I bought the 4-Season because I prefer the extra protection vs their normal racing ones, however the 4-Season tires are fast tires too. They are light, great traction and have not had any issues with them (only had 250-300 mi on them). I was riding Schwalbe One DD before, and I can say that Continental GP 4-Season seem to provide a smoother ride with better rolling resistance.
I am a daily rider, 20 to 30 miles. I have been using Conti GP 4-season's for years. Fronts last me 12000 to 15000 miles, rears 8000 to 9000 miles. There is not a thing I don't like about them.
I really enjoy riding on Continental tires. Typically in nice conditions I'll be on Conti GP4000IIs tires but, when I know conditions will be poor and the road may not be very nice, I like to slip on these Conti GP4-Seasons.
I've used these tires for when I'm going to do a long ride in the rain or when I'm going to be going over more difficult roads. I feel quite confident taking these tires through a slightly rough gravel trail section without having to worry about a puncture.
I also used these for a criterium which took place in the rain. A few guys fell in a set of technical corners but I was able to get through with confidence with these tires.
All in all, I would recommend having a set of these 4-seasons on hand in case you are going to be riding in off weather. Or if you expect to be riding on mixed roads, they are quite robust in terms of puncture resistance.
As a 71 year old retiree I have the privilege of riding a titanium Habanero crosstour bike with disk brakes for 150 to 250 miles each week. Plus the Continental tired Habanero takes me on 2 or 3 tours of 300 to 400 miles each summer. I pack light (- 40 lbs) and the 4 Season 28 mm tires carry that total 225 lbs over country roads and hard packed gravel with ease. I buy a new set for the summer tours then ride them out in the wet falls and winters of the Willamette Valley. They flat seldom. Unavoidable road debris cuts the tread but the tough core protects the tube. The slight increase in tire weight provides a security tread for all conditions increasing my confidence in cornering at high speeds. Yes, 71 year olds can attain high speeds and corner without causing heart attacks or strokes. I trust this tire more than any (and I have bought and replaced many tires). I could but wont' name a few duds that cost about the same.
I've been riding the 28mm version of these tires in the beating down rain, crud, gravel, branches, rocks and muck on the side of the road in Pacific NW springtime. No flats, traction is very reassuring and the tires feel great. I ride them at low pressures (65-70 PSI) on wide-ish rims. Did I mention the ride feel is great? Comfortable, not harsh. I've ridden other 28mm tires at the same pressure and those others are not as comfortable. Can't speak to long-term durability but so far they are holding up great with a few hundred miles on them.
Note these are muck and grunge training or commuting tires, not racing tires. That's what I rated them as. If you want lightweight racing tires with low rolling resistance, these ain't those. But as winterspring training tires, these are the best tires I've run in years. Very satisfied.
I picked up a pair of these while on sale at a great price. I use them for general road riding/training and for a few gravel-grinder organized rides (Hell of Hunterdon, Fool's Classic). After using several brands/models of tires, these have held up the best for the gravel roads. MUCH better than GatorSkins which I have had terrible luck with tearing the sidewalls on several. This is a much better tire IMO and a better price. Supple enough to use as a daily road tire as well.
I'm 140lb and the 25mm work well for me - I don't like the ride/feel of wider tires. Zero punctures, flats, or tears after many miles of rough gravel.
I run 28s on both my winter training gravel bike (CX) as well as a tandem. I've ridden on all kinds of gravel roads and even on a few MTB trails with them. On the tandem we've recorded descending speeds of over 60mph and find them totally trustworthy. Logically, they are slightly heavy, but otherwise great handling, super durable, and hard wearing. My go-to tire.
Have always had good luck with Continental tires, and I especially like the GP 4-Seasons for my winter bike due to its nice ride quality, excellent grip on wet pavement, and decent flat resistance. The tread compound does seem fairly soft, which is undoubtedly why they grip so well, so they may not last as long as tires with a harder compound - but for me that's a worthwhile trade-off. I'm happy to get 1,500 - 2,000 miles on a set of tires and the GP 4-Seasons will do that easily.
