Continental Ultra Sport tires
Hi all, I've used mostly Continental tires for over 20 years and nearly 100K miles of road riding. Recently I got a half dozen Ultra Sports (700c x 25), and after putting a new on on the front noticed a definite bounce as it rolls. I've tried three now, with the same results. The wheel is very true and round, with no flat spots. This review includes a video that shows what miine look like: https://www.amazon.com/gp/customer-r...SIN=B00HPSCDBE On top of that, they are damn hard to mount on the wheels! I've met few tires I can't get onto the rim with just my hands, but these are almost impossible to mount even with levers. Is this a known problem with this model of tire? I've used the Gand Prix and other models before--mabey have used the Ultra Sport before, but don't keep close track. Any suggestions are welcome. -- Ted Heise West Lafayette, IN, USA |

I have the same problem with Schwalbe 20 inch tires. The rim manufacturers and the tyre manufacturers are just a dinkleberries in disagreement. I am on my third rim and tyre combo. Still tight AF but will just fit. Deflate the tyre. Lube up the bead with some soap. Inflate to "Holy mother of god! How much?" PSI It may decide to pop into its seat properly. Or it may not. Good luck. -- davethedave |

Also, I inspected the seating of the tires pretty carefully, and there is no apparent difference in tire placement around the rim. On top of all that, wouldn't the bead either seat or blow out on riding for hundreds of miles? -- Ted Heise West Lafayette, IN, USA |

Some tire and rim combinations a just bad, and you can get a tire that will not bead without soaping, beating, prying, pumping, etc., etc. Untreated, the tire will not bead no matter how long you ride it. Ultra Sports are an unhappy combination on my Sun CR18 rim which has a shallow rim well. They're tight, but they do bead and are round. I quit using them because of poor sidewall durability. I never had one that was mismanufactured. -- Jay Beattie. |

I suppose there is some small chance that I got a group of defective tires from a bad manufacturing run, but the non-beading point does seem more likely. I should have added that getting the tires off takes some active inward pushing to get the bead out of the hook on the rim. In some spots, a surprising amount of force is needed. So this too points to bead seating problems. I will try one of these tires on another bike with different rims, see what I get, and report back. It also seems like my best bet is to go with a different tire for this bike. I'd like to stay with Conti's but don't want the expense of the Grand Prix.

The 4-Seasons ride really well, but because of cost, I typically buy the Michelin Pro4 Endurance for a winter fast tire. The Michelin are consistently on close-out. Otherwise, its the GP. I think there are better deals on Michelin and other tires domestically. -- Jay Beattie. |

Any suggestions? -- Ted Heise West Lafayette, IN, USA Ted, this is quite easy to see - there is a line that would normally be showing above the rim edge. That is symmetrical so if that isn't showing in about the same height above the rim all the way around you've discovered your problem. |

Continental presently isn't making a tubeless tire but they told me that they should be on the shelves in the spring. |
