Hi,

Time to have my tires changed. Any better tires compared to the stock Dunlop Sportmax D214? Especially handling in wet weathers ..

Michelin Pilot Road 4.
I completely agree. I ran the Pilot Road 3's on my last bike. I put 16,000 km (Just about 10,000 miles) on them and they still had some life left in them. I took them off because of a huge trip I was going on and gave them to my friend who ran them on his R6 for a summer. I ended up replacing them with the Pilot Road 4's and was not disappointed at all. They are amazing tires in the rain and great in dry conditions. Still quite sticky after you warm them up. I can't wait to wear out the Dunlops on my Z650 so that I can upgrade to the PR4's. Highly recommend.

Changing to a 170cm wide tire will change the final drive ratio by 1.89%. You will see a respective top speed gain of 1.89% and a torque/acceleration loss of 1.89%. Meaining instead of a topspeed of 113.5MPH, you'll have 115.7MPH. It will also change the accuracy of the speedometer by the same percentage. Now for the actual fit, and clearance of the tire, It should fit, but I wouldn't go any wider. As you corner, the tires are designed to flex to create a wider footprint at an angle. If you don't change the rear rim, you will create a pinch, causing the 170 to be taller and more rounded than intended. What this will do is change the contact patch area of the tire. You will be leaning on the harder, center section of the tire at times, instead of the softer, outer edges.

In short. Yes, a 170 will fit, but you are gaining literally nothing other than looks unless you fit the correct rim to gain the added traction and footprint a wider tire provides. And, you will probably pay more for a 170, since it's kind of an odd size to begin with. I would stick with 160's and buy a good dual compond, such as the Michelins.

Thanks Tremonte for the detailed response. I will stick with the 160s for now. On top of the Michelin PR4, are the Bridgestone S21 or the Pirelli Diablo Supercorsa any good? i use the bike on the weekends for canyon rides with windy roads, not so much on a rainy day.

Do the PR4 perform well on corners as well?

I've never tried the Bridgestones or looked into them much. I have heard good things about the Pirelli's as far as performance, but they tend to wear down a bit faster than most other tires. The Michelin's are great tires. I've had several sets through the various iterations of the Pilot, and have never been let down. Great mileage and excellent traction.

When I bought my z650, new, from the dealer, I got him to change, prior to delivery, to Pirelli Angel GT tyres. These have become my favourites for great grip and long life on previous bikes. I also went to 170 profile from new, however I am finding it not quite so easy to scrub the shoulder.
