I think I need new tires for the road bike. I've been running Conti 4-Seasons (700x23) with pretty good success. The sidewalls started showing some wear recently, so I swapped back to the new Roubaix Pro tires that came with the bike (bought the bike last year, but decided to run my old wheels with the contis). Also was most recently running the 4-seasons on the DT Axis 4 wheels the bike came with.
Maybe it's just me, but the bike now feels squirrely at speed; much more so than it did with the 4-seasons. I plan on replacing the Roubaix Pros with either another set of the conti 4-seasons, or the new Gran Prix 4000S II. Wonder if any roadies have a preference between these two contis, and if anyone's ever experienced the dreaded wobbles on a road bike, and what they've done to address?
Never had the wobbles. What speeds are we talking?
I am really not knowledgeable at all about road tires, but since several friends who are (knowledgeable) recommended the Vittoria Corsa EVO CX a few years ago, I haven't looked back. The ride quality is noticeably sweet, coming off some earlier Michelin Pros and Krilions, and Hutchinson something-or-others. That said, I am light and am not a really high-mileage rider. I just last week had to ditch the first one I bought ... was on the front for a while and got moved to the rear in spring 2013, I think. So it probably has something like 3,000 mi on it, of which probably 1,200 were on the rear. It wasn't quite worn down to the carcass, exactly, but in the process of trying to dig out whatever the heck that hard object was in there that produced the pinhole in my tube I kind of trashed the think layer of rubber that was left, so I decided not to be pound foolish and tossed it. Cannot make a first-hand comparison with any Conti road tire.
Confess I am a bit biased against Conti. They make nice-looking sidewalls. Had several sets over the years on my cars and was never wowed by anything about them. A decade ago I had a set on my MTB and ... ditto. Like several Euro tires I've tried (including the high-end Nobby Nic EVOs), the compound did not seem to suit local conditions, though it wore well. Then about five years ago I put one of the made-in-Germany Black Chili tires on the front of my 26er. I was really impressed by that tire in terms of mud-shedding, light weight, and true-running tread. Unfortunately I sold that bike and went to a 29er shortly after, and that almost-new tire went with the old bike. Then just this season, with that experience in mind, I put a Conti X-King 2.4 on the rear of the 29er. As before, the tire is true and the compound seems good. The tread pattern also seems to be more well thought-out than some of their earlier efforts: Feels quite fast but it's still got just enough bite to instill confidence in the corners. It also transitions from upright to leaned-over better than the Ardents and Eskars I've been running the past few years. So, I was pretty pleased all around. I liked it enough to put its sibling Mountain King on the front a couple months later. That tire has good purchase in corners, but unfortunately this one is pathetically wobbly in the "is the tread straight?" department - what I'd expect from a $20 tire, not a $60 tire. Probably nothing I'll notice while riding (?), but it bugs me.
The really bad thing, though, I'm realizing a bit belatedly, is that the wear on the rear tire is shaking out to be pretty poor. About a quarter of the outside knobs on the X-King already have hunks missing after less than a full season of very moderate use, and all the outside knobs are distinctly worn on the inside face. This is particularly disappointing because what led me to move away from the Ardents was that I got tired of what seemed like premature wear in that area. I guess my expectations were too high, because at the rate things are going I'm going to need go back there before the end of next season.
