Andrew 03XX Posted November 2, 2005 Share Posted November 2, 2005 I just replaced the worn BT020's on my 03XX with Michelin Pilot Roads. The general feel is excellent, but above 140 kph (87 mph), there is a vibration in the front wheel that was not present before the tire change. At 150 - 155 kmph, it feels like I am riding on a knobby tire. There is no wagging or weave or slap, and the ride is very smooth below 135 kph. I returned to the shop (a very trustworthy mechanic) who rebalanced the tire, but this did not help. The shop is ordering in a new tire. Anyone have a similar experience? Many thanks, Andrew 03XX 28.5K km Quote Link to comment Share on other sites More sharing options...
beondwacko Posted November 3, 2005 Share Posted November 3, 2005 Not here. I had the PR's mounted about 400 miles ago , and the bike is as smooth as ever regardless of speed. I agree with the general feel being excellent. Sounds as if you may need a rebalance. Odd order harmonic going on there. Quote Link to comment Share on other sites More sharing options...
bhanxx Posted November 3, 2005 Share Posted November 3, 2005 On 6th set of Roads, been smooth as a baby's bottom from start to finish front'n'back w no cupping up front :clap: . If shop reordering front, wait'n'see results, if still problem, then worry about other culprits.... Quote Link to comment Share on other sites More sharing options...
BarryG Posted November 3, 2005 Share Posted November 3, 2005 Just replaced my tires 500 mi ago with Pilot Road rear and a Pilot Sport up front....never had a front Road before but so far set up I have works fine. Quote Link to comment Share on other sites More sharing options...
azxx Posted November 3, 2005 Share Posted November 3, 2005 I run a Pilot Sport front, Pilot Road rear, no problem but I did have a front 208 that was smooth till I went over a 100 mph then it vibrated, the balance was ok, just a bad tire or it needed to be speed balanced.

bartonmd Posted November 3, 2005 Share Posted November 3, 2005 About to finish up my second set of 'roads... Not a problem with them... You may have gotten one that was slightly out of round or the shop that mounted them MAY have popped a chord when mounting it, if the machine got fucked up while they were doing it, or if they didn't push the one side down into the middle of the wheel while getting the last of the tire on the wheel... Anyway, not somethign that's seen all the time... I've never heard of it... Mike Quote Link to comment Share on other sites More sharing options...
blkbrdrydr Posted November 3, 2005 Share Posted November 3, 2005 Interesting! When my 2nd set was mounted, I wasn't entirely comfortable with the ride of the front tire either and had the shop rebalance it. There is still a different feel than my first set but since I have 4,000 miles on the tire, I doubt that Michelin will replace it. However, I do believe that the tire is not exactly right.

blackhawkxx Posted November 3, 2005 Share Posted November 3, 2005 Anybody who has worked at a manufacturing plant knows that it wouldn't be to hard to get something that just isn't perfect. Most plants are happy with a 97-98 % of good product. Well someone has to get the other 3%. :cry: Quote Link to comment Share on other sites More sharing options...
RichardCranium Posted November 3, 2005 Share Posted November 3, 2005 I find this interesting as well. Since my wreck I have had a vibration that is most noticable around the speed you indicated. I have tried to isolate it and have pretty much determined that it is the rear tire. I guess I should mention that I put Pilot Roads on after the crash. I am about to replace the rear tire with a new Pilot Road because its about worn out. I hope its the tire and not something else that got tweaked when I went surfing.

Helvet Posted November 3, 2005 Share Posted November 3, 2005 Probably the cord-harness is not 100%. Can you tell us the production date? It is a series of 4 digits, weeknumber and year..... For instance 3605 is week 36 in 2005. Quote Link to comment Share on other sites More sharing options...
Andrew 03XX Posted November 4, 2005 Author Share Posted November 4, 2005 Thanks for your thoughtful replies! The date code on the tire is 1805, or 18th week of 2005. I will report back after a new tire is installed next Wednesday. Andrew Quote Link to comment Share on other sites More sharing options...
Andrew 03XX Posted November 13, 2005 Author Share Posted November 13, 2005 The vibration at 140 - 155 kph was entirely eliminated with a new tire (another Pilot Road front). Some very slight vibration remains at 170 kph. Andrew Quote Link to comment Share on other sites More sharing options...
pug Posted November 14, 2005 Share Posted November 14, 2005 Do you run 42 psi fore and aft? Quote Link to comment Share on other sites More sharing options...
Andrew 03XX Posted November 14, 2005 Author Share Posted November 14, 2005 I tend to run slightly less (37 F, 39 R) on all tires that I have used, but I will try going back to 42, 42 to see if this makes any difference. Andrew Quote Link to comment Share on other sites More sharing options...
