New Dunlops

The other day I replaced the original Metzelers with new Dunlop Sportmax Roadsmart III and made the following observations: smoother ride, quieter ride, softer handling, somewhat higher wind sensitivity, and you know what - left pull is gone, completely gone...

When it's time to replace the original Bridgestones on my GTL, I'll probably go with those Dunlop RS III.

The left pull will come back when the tire wears in.

Is the left pull related to tire cupping? All bike tires cup eventually - sounds like the L pull may show up around the time the tires start cupping.

I know I'm going against the grain, but my one set of Dunlops will be my last. They ARE great when new. But I also noticed the highest degradation in handling anomalies as they approached the wear indicators. In fact they were the worst at getting straight line squirmy as any tire I've tried. I've tried pr4's, metzlers, pirelli Angel gt, and Dunlops. The PR4 tires offer the best handling over the life of the tire = safety in my book.

I've come to the conclusion that tires like other products are made with certain customers as a target market. When used by customers that ride outside that design envelop, they are disappointed.

Not putting anyone or any tire choice down, all the choices available are designed a little different to excell within that envelop. Be it longevity, wet traction, dry traction, touring.

Soon I'll find out for myself. I ordered the Dunlop RS3 tires for my B. Will post what i think.

I just put a set of the Roadsmarts on my GA and they ride great but are much noisier than the original Bridgestones. Hoping they quiet down when they wear in.

Hi guys,

I fitted RSlll's on my GTL a few days ago and have since done around 3,000kms on them replacing the original OEM Bridgestones. Grip and stability are much improved, moreover the left pull I did have on my 2018 GTL has gone.

Initially, when the Dunlops were brand new, a left pull was still evident though reduced by say 50%. More of a gentle slow turn as opposed to a distinct pull as before. Since then I've had something of an epiphany......

During a 13 hrs ride up to the north German Coast and remembering a previous comment gleaned from a member, I moved position on my RDL seat slightly to the right. (I will go back through the threads, try to find him and say thank-you). NO TURN OR PULL, it had gone. If I moved a little more to the right I could get the bike to pull right when the bars were released. Now all these things are somewhat subjective but it would appear that over the years I've adopted a slightly left of centre riding position. Clearly my GTL, with or without Dunlops ( I have no comparative evidence) is sensitive to weight distribution. I assume others will be the same? After a little practise and shuffling around I could find the sweet spot as a matter of course. The bike now stays straight for a short while before turning LEFT or RIGHT dependent on the conditions of the moment, camber, wind etc.

Other variables are a new CalSci Screen and an RDL seat, though on the face of it they do not appear to be a factor.

Once again thanks to all, this forum has improved my knowledge and therefore enjoyment immeasurably.

Safe riding and best regards,

Tony
