Hi
about to buy new tyres; Michelin Road Pilot 4.
the RP4 come in 3 models, STD, GT, Trail, the treads all look the same on the web.
Std come in a 180/55x17 vs 170/60x17 which is the OEM size
I can get RP4 GT in the OEM size of 170/60x17.
My question is, has any one tried a 180 wide tyre? Does it fit, any negative or positive experiences?
regards Nigel

Hi Nigel.
I had a 180/55 on the back of the 907 when I purchased it. The rear shock at some stage was knackered, so the 180/55 tyre went up and wore through the guard. I have since fitted a 170/60. The old 180/55 tyre didn't feel as good to ride on. It wasn't overly worn either.
Cheers.
Nick.

thanks Nick me thinks 170/60 is the way to go.
You'd be better off with a solid tyre up in Broome ay? I cant imagine you wearing the edges out around there!! Have you ridden the 907 on the dirt much?
For our Northern friends you should google Broome. Its a stunning part of Australia, on the border of the Pilbarra area [my favourite] & the majestic North west Kimberly region. Pretty isolated, you drive 800 km south to the next big town, Karratha on 'almost' straight roads, and then go north for a coupe of days to get to Katherine. Not many tourists go there, but that whole area is just stunning.

the 180 is permitted officially by Ducati.
Years ago I Asked them if it could be fitted and they issued me the "nulla osta" a letter confirming the fitment which is a legal requirement to get the new size marked on the bike Logbook; In ITALY this is necessary as without it the bike would not pass the Italian MOT with the different tire size.
As far as I know Ducati (or any othe manufacturer) would never issue the Legal document if the modification is not approved by their technical department.
As far as the tyre choice is concerned, unfortunately, the 170 limits the range of available possibilities.
I found myself strugglying to find a nice soft Pirelli, I then changed to Dunlops (Qualifier) and I have to say the bike rides VERY VERY well (dunlop's front tire profile is "quicker")
I have not fitted the 180 yet, but I will when it comes the day I cannot find a sport tyre in the 170 range

Isn't 160-180 legal on a 5,5" wheel?
180 makes it steer slower, 170 better. PR & 907 lovely match.

ah yes, Port Headland! duh Nigel. I worked on a prawn trawler out of Point Samson in 92 [i think], as I drove around Oz in a Kombi.... I went to Millstream NP. I would love to go back on a bike [dirt] and tour around. Whats a TonofAir? I had a Dominator set up for it years ago, but just never went! Ok , plenty of grey nomads, but overseas tourists rarely go there compared to the east coast is what I meant. Forget the GOR these days, 80kph all the way, the local DOCV does a ride every second week. I like doing the Snowy Ride, take a few days to go camping on the bike riding the Alpine hills. ciao
