Veteran  1016  Deep South, Georgia |  Subject: Tire opinionsWondering if there are any opinions of the Conti 4000 GP vs. the Michelin Pro 4? I know the Conti's are highly regarded and I had the chance to pick up a set a few months ago when they were on sale knowing that I would be needing them as soon as I picked up my new wheels for this season. As it worked out, I ended up not buying new wheels but found a great deal on a slightly used set of HED's. The HED's came with an almost new set of Pro 4's. So would you stay with the Pro 4's on the race wheels or change them out with the Conti's? |

New user 230  penticton | Subject: RE: Tire opinions in term of difference, you are talking about 2 excellent tire. the continental tire gp4000s as been tested many times and is one of the lowest in term of rolling resistance. the micheline pro4 is doing good also but not as good. if you are to buy a pair of gp400s, i would kept those for racing and use the pro4 for training. that said...both are very good, we are talking a difference of 2-3 watts in favor of gp4000s. in term of flat resistance, they are pretty much equal.... |

Expert 2192 Greenville, SC | Subject: RE: Tire opinions i've owned and used both. the pro4 isn't very durable. GPS4000s or go home. that being said if it is only a set of race tires you are talking about then the Pro4's will be fine. its when you start getting +800 miles on them you need to start looking at another set. |

If you aren't sure what those reasons would be... use the 4000s. The only reason is if your LBS is out of GP4000s and you are in a time crunch. This analysis by Tour magazine has good data and concludes the GP4000s is the best. |

Pro 5361 | Subject: RE: Tire opinions all tire questions result in the same answer: Conti GP4000S. the black ones are better than the colored ones. (the new GP4000SII you can buy in colors with no degradation) |

Pro 5361 | Subject: RE: Tire opinions Originally posted by Dominion So it sounds like it's unanimous. I guess I'll be changing out the Pro 4's. Thanks everyone! Yeah, take'm off your race wheels, but certainly, use the hell out of them on your training wheels. they're still excellent tires with a great road feel and very good traction. I enjoy riding them (well, that was until I got a sidewall cut after 500mi and needed to boot it to get home). |

I've had them myself, and seen many others with sidewall cuts while using the Michelin PR3 tire. Not to say that I haven't had a sidewall cut on other tires, including the GP4000S...it just seemed like it happened more often on the PR3. Never tried the PR4. |

Member 251 Phoenix AZ | Subject: RE: Tire opinions Wondering if there are any opinions of the Conti 4000 GP vs. the Michelin Pro 4? i run the continentals on my road bike with zipp 101s. great tires - comfortable, fast, low rolling resistance. but i've had several explosive flats that caused the tread to separate from the sidewall - one coming down a hill at 30mph. seems to happen every 1500 miles or so. i've heard people claim to get 5000+ miles out of these tires, but that strains credulity. i run the pro 4s (service course) on the time trial bike with flo 60s. they are virtually indistinguishable from the continentals, except that they feel "grippier" if that makes any sense. that may be because i run them at a lower psi because the flo 60s have a wider rim. plus the michelins are cheaper and i haven't had any flats yet (with around 1000 miles on that set). |

At 18.6 mph for the Pro 4 SC Comp / per tire maybe! There are several flavors of the Mich Pro 4, with the Comp being on the upper end of the fastest for the bunch. For race wheels, GP4000S+latex all the way. |

Veteran 294 Mission Viejo, | Subject: RE: Tire opinions Unfortunately for me, the financial end of things is an issue. Never rode the Conti's, so cant speak on them. But, at $23 a tire, I very much.like the the 2nd set of Pro 4 Service Course that I just got a few days ago. The first set only has 350 miles on them, so we'll see on the durability. But, they look brand new so far, not even so much as a nick in them. They roll very well, and feel great. I run them at 105 rear, 100 front with no issues. I did notice on the first few rides that the bike was just a bit less stable, had to check thinking I might have had a loose front end. 100 miles in and no issues. Once the tire had flattened out a bit, all was good. Most likely stick with them at that price! |

Member 326 | Subject: RE: Tire opinions Having heard all the good things about the Conti's I went ahead and bought a set of 25mm ones. Here is my mini rant for the day. Local bike shop carries these tires, they want $85 each, plus 13% tax. I ordered 2 from the UK and they are being shipped to me in Canada for less than the price of one. I am all for supporting the local business, but $192 for 2 tires when I can get them shipped to me for $94 is just crazy. |

| 287 | Subject: RE: Tire opinions Michelin Pro "series" tires have been my go to since the, well, the 1990's. Never had an issue with flatting or any kind of cutting that would have reduced tire life. I have used these tires on 32 spoke training wheels to zip race wheels without worry. Good bang for the buck value when one shops in the off-season. If the best riders in the world use these tires, then there is no reason why this older and over the hill weekend warrior can't do the same. |

| 1055 | Subject: RE: Tire opinions Red side wall on my pro4 matches great with my red bike. They've been durable and are cheaper than the conti's. there is no way the conti's are 2 to 3 watts better. Over a 40k, I doubt the difference is more than a second. |

I actually train on the red pro4s for the same reason. I can also roll on them for close to 3k miles before they start to come apart. They're really square by then, but they're training tires, so who cares? A side bonus is that they last forever on the trainer as well. That said, I've got conti 4000s on my race wheels  |

The difference much more than a second according to the guys at flo that did the comparison in a wind tunnel http://flocycling.blogspot.ca/2013/04/flo-cycling-flo-30-wind-tunne... Rolling resistance of a tire isn't everything. There is an aero component to it. this is th time savings of the flo wheel over a mavic with the different tire options. The conti is 15s over the Michelin, on an olympic distance  Edited by marcag 2014-02-07 4:38 AM |

They've been durable and are cheaper than the conti's. there is no way the conti's are 2 to 3 watts better. Over a 40k, I doubt the difference is more than a second. You're right. At 30km/h it tested 2.5 watts better, at 40km/h 4w better (or 5w & 8w respectively for 2 tires), as tested by a high respected individual (his blog & data). If your racing without latex its even more. As Marc pointed out, the aero benefits are additive. If you're after every possible second, they are absolutely worth it. I have yet to pay more than $45 with shipping for one online. |

| Subject: RE: Tire opinions I've seen the testing with the GP4000S by FLO and Zipp. How much of the aero benefit do you think is from the tire alone being aero, as compared to how the tire meshes with their rims? I ask because my race wheels are 2008 Zipp 404s, which have the more traditional 19mm wide brake track. The recent testing that FLO and Zipp did is with their new wider rims.

I really don't know, but to be sure, you need to buy new FC zipps. Just to be sure ! Kidding aside, I don't know how much is the tire/rim effect and how much is the shape of the tire. But for the little difference in $, I'd go for the Contis. I would not go off and change newly installed tires, but I would definitely buy Contis when time came to change them. PS : Hed also recommended them |

for a 19mm rim I would recommend running a 20mm conti SS |
