Fixing Tyre Wear By Adjusting Rebound On My Ducati SuperSport

I had this wear pattern on the tyres of Boe, my Ducati SuperSport 939, where one edge of the tread is higher than the other. Thanks to advice from motorcycle suspension legend, Dave Moss, we fixed it with a rebound damping adjustment (and some compression damping adjustment too) to the forks and shock. I learned just how complex an interaction exists between tyres and suspension, and how important it is to keep an eye on how our tyres are wearing, to get more life out of them.

Thanks so much for this video!. Ive been riding for decades and mostly only adjusted suspension on rudimentary feel. Ive had many tires wear out early due this tire scalloping. Decades ago, I was told by a bike mechanic that it was tire pressure. So I'd been faffing around with that. This is so helpful. Thanks!

@staceonwheels me too. My suspension is adjustable, so Ive got some work to do.But my wife's isn't. So I think spending some money on upgrading her suspension will help save her tires... and give a much better ride

Wow, cool. I found this accidentally. As a newer rider I've been chasing a rear "feeling" I couldn't quite put my finder on until I did a ton of reading. I thought it was a wallowing feeling until I ran into a page with a bunch of terminology that had wallow and pogoing. Turns out it was a pogoing feeling as described here... "Uncontrollable rebound. Can feel like a figure 8 motion in turns or riding over marbles, caused by lack of rebound dampening." And my tires look exactly like yours on the tread edges. I increased rebound damping quite a bit and reduced high and low speed compressing damping. The bike feels so much better, more settled and more confident cornering. Like you said cornering feels better, way better in my case! It's a different bike to ride now! Amazing how little changes make big difference right?! Enjoy!

That's brilliant to hear! And glad my video helped a bit in your investigations. I'm going to keep playing with suspension settings to learn what effect dufferent damping amounts have on how it rides, cornering and braking in particular. I hope to do another video about this in future. Enjoy your "new" bike.

Hi Stace, I understand what you are trying to fix and you are quite right about the rebound, but, this does not mean you have to adjust the compression. These two things work independently and fix two different problems. They should be adjusted to suit your riding style and the roads you ride.

Stace, I enjoy your content. I will be purchasing the 950s in the next few weeks. I am so encouraged by you. I’m trading in the Harley Davidson for this sweet new ride and adventure. I’m 5’3” and on the smaller side but she feels great under the legs. I’ll post when I have her. Her name will be Valentina 👍 I’m located in Southern California and can’t wait to take her on Mulholland Highway 💕🇮🇹

How exciting... new bike day coming up! I am sure you'll love your 950. Since I got mine, I've met 4 other women locally who have SuperSports. All of us are short like you, but all found ways to make this bike managable and all of us are in love with them. I look forward to hearing when you get Valentina.

I'm on a new set now and this time Rosso 4s. They seemed to be wearing evenly for the first few thousand kms but you prompted me to check again and I see now the same wear pattern is happening again to a lesser degree, suggesting still too fast rebound on the rear and too slow on the front. I'll adjust again and see how that goes.

​@@staceonwheels Dave moss is a snake oil sales man who preys on people who don't know any better. Ohlins, you know the guys who make suspension have even said that suspension cannot be set up based of tyre wear. If there is a problem with tyre wear you should probably look at the tyre itself, is it run at the correct pressures, correct temperature, what level of abrasiveness are the roads? how hard are you on the tyres? there are just to many variables that Dave omits and uses 0 data points to adjust the suspension He essentially puts a bandaid on the problem when you need stiches. You don't need the suspension set up by tyre wear, what is better is to set it for your weight and then find what your preferance is

Great video Stace. Can you help, or anyone else? My bike suffers with the same front tyre wear as yours in the video. Rebound on my forks is set to factory setting (two full turns out from fully closed). When you say the rebound is too slow, how does that translate into Hard/Soft?? The manual only refers to rebound as being harder or softer, not faster or slower. Thank you
@staceonwheels
@staceonwheels 10 ай бұрын
Too slow means too soft I think. It means not enough damping. Plenty of info on the interwebs about it. I'm just learning!

@@staceonwheels Hi Stacy, THANK YOU for the reply!. Will you do an update on this, after you have done 500 miles or so? Would be good to see if the uneven wear appears to continue, or it goes some way to healing itself. I have two bikes with the same exact issues as yours and its annoying that the manufacturer does not give any info in the manual about how to read your tyres, but then again they they are in complete denial about changing the fork oils!. Also this compromises the life of our tyres greatly. I got the answer from a suspension guy about rebound slow/fast. If the rebound is too slow it is too hard, if it is too fast it is too soft. On the forks, you would have dialled the rebound out (anti clockwise) to make rebound a little faster, from the position it was with the problem. Essentially this opens the rebound valve, to allow oil to return quicker, with the help of the spring.

@timsloan-cj2pl I did notice some improvement but not a lot. Those tyres were getting close to end of life and I'm on a new set now. I changed the compression to have a bit more damping because it felt better. Will see how the new tyres go and might do a follow up video, thanks for suggesting.
