I use them on my best bike if I've found some in a sale, otherwise I use Vittoria Rubino Pros which are not that far behind and half the price.
For transport type riding I prefer Marathon racers, the 30mm size are just a touch over 28mm on OP rims, not quite as easy rolling but last a lot longer and with better puncture protection.
Totally agree PH. This week I got a pinch puncture in my Rubino Pros and as they were both looking smooth I replaced them with some new GP4S's that I had brought for a bike I am building.
I am certainly now going to buy some more Rubino Pros as they have served me well and now my grandson is working at Halfords part time I can even get a discount on them.

i not certain that the second link does indeed review a four seasons version of that tyre. those are a more race oriented one the 4000s...some sort of special black compound in the tread.

Yes your right - sorry - my mistake . Though I still have the "4season's", which are 2008 vintage, on one of my bikes.
These where the tyres that I hadn't inflated properly after a quick assembly. Rode the bike just to check the gears and then put it away ready for the next days ride. Next morning, discovered the flat tyre and found the "snake bite". Inflated them properly ever since. The other 2 times where on the Grand Prix GTs and both due to hitting pot holes.

^ I agree. You can spend a lot more and gain relatively little benefit in terms of increased puncture resistance.

Rubinos or whatever Schwalbe Active Line tyre is the right size is probably the best compromise at the moment.

Agreed.
These are great.

For anything short of absolutely needing crampons, they are the business. I've walked across seriously sloping sheet ice with these. They are also good on very steep wet grass.
I wear Yaktrax. They aren't quite as aggressive as the things in the link, but they are enough to compliment cycling, and using public transport. I've walked a couple of miles with Yaktrax on my boots and they're fine for that. They're good for mixed conditions, and even a fair amount of shear ice. They aren't good for long distances on shear ice, though they're better than unenhanced boots.

My last ice crash was on a treated road. The buses hadn't started running yet and I think there just hadn't been enough traffic to work the salt in and melt the ice. I bought studded tyres after that. They run slower than molasses in January but resolutely keep gripping in everything we've had so far.
I have too (commuted year round, for 20+ years), even on - when I was using that bike - '20' section tyres, in winter (as they were all that would fit with mudguards, & Salmon Profil, at that !!!!)

If it's too bad, I'll run instead (I try to alternate, run one day, ride next)

It's either a case of fell-running shoes, if deep snow/slush
Such as my Inov-8 'Mud-Claw 330' (note peat-bog tide mark on legs!!, & Cycling club jersey)

If it's icy, I have another pair of Inov-8's (OROC-340) , which are really meant to be orienteering shoes, but great in ice, as they have tungsten studs!

Marathon Plus (if you can tolerate the added weight).

I bought some '28mm' 4 seasons in the summer as they were on offer at Halfords, honestly not impressed. First off they are very narrow for a 28mm tyre at a measured 26mm on a DT Swiss rim (which is very disappointing!)
Grip is very good but not immense, rolling resistance is average IMHO and for the price you can do a lot better in my humble opinion. Puncture resistance maybe very good but then I don't flat that often on any of my bikes, can't remember the last flat I had on a non commute/utility bike.

I bought a pair of Giant PSL2s at closeout from Rutland for cheaps and they are much closer to 28mm, and replaced the Contis pretty much straight away. They roll really well are grippier and corner much better and 'feel' a lot nicer at similar pressures. There's a puncture belt too but not having flatted on these either I couldn't say if they were any worse aside from the Conti's sidewalls are more robust (I've never had a sidewall puncture in 30 years road riding so not something I'm personally bothered about)
They're £12/each here, even with postage almost half the price of the conti's http://www.ebay.co.uk/itm/GIANT-700x-28 ... 1176860373
A Schwalbe Ultremo 28mm if you want even faster rolling
My 2p worth

Re: Yet another tyre question

Another thumbs up for GP4Seasons. They are costing me less than 1p/mile given that I'm getting 3500 miles from a tyre though I did stretch this to 6000 by swapping from rear wheel to front wheel. I won't pay anything over £40 for them, usually paying £32 from Wiggle or pricematching them at Evans or Cycle Surgery.

This might sound stupid, but after thinking about what could happen, I'm going to include a pack of antiseptic wipes (and maybe a bandage) in my saddlebag.
Definitely agree with taking it easy and not going for a PB this time of year.

PhilWhitehurst wrote:Most councils have a map online showing their primary and secondary gritting routes. If a road is dry and it's cold then it's fine to ride, even on icy days. Bridges are often icy as the air below cools them. Just ride to the conditions and if you front wheel twitches glide to a halt and walk a bit. Icy stretches rarely last long unless a road takes a lot of drainage. Roads that catch the sun are better in these conditions as its able to melt the ice. So east / west lanes with no a lot of shade are good.

+1. I print off my local councils gritting map and whenever there is a chance of ice, I only ride on the roads that are indicated as being gritted. It's mostly main roads but there are a surprising number of minor roads that also get gritted, often because it's a bus route.

Another fan of Conti 4 Seasons. If you don't pump them up too hard they are supple, taking out some of the buzz from the road. They grip really well on wet roads, they resist punctures well, and they don't wear down too quickly. And they are very light and fast. Great for all year use. The clue is in the name.

+1 for Conti 4 seasons. I have been using them since October and covered ca. 2000 miles in all weathers. I have pulled out a few pieces of glass and flint which I would have expected to cause a sudden deflation event on other tyres.

I'll be happy to leave them on all year round. I ride at a reasonable pace and they seem fine in that respect.

Yet another tyre question

16 January 2016 - 7:05pm
New tyres required, in 700x28.
I don't do winter tyres and then summer tyres, I just fit a pair of tyres and ride them.
At present I am using Vittoria Zaffiro's, these were given to me, but these need replacing.
I ride for transport, some light touring and some longer day rides.

All year round grip is important, I don't like p******e's and I'd prefer little rolling resistance. So what is the 'perfect' tyre?
