Uneven tyre wear

[Hawkeye1250FA]

Odd one this.

Checked tyres at the weekend (PR4s done about 4k) and noticed that the front tyre is wearing much worse on the right side. To the point where it almost needs replacing - whereas the left look useable for another 3-4k.

I'll stick a photo up later. Any initial thoughts on what would cause this? Other than me doing mostly right turns! 🤣

Do you use a lot of roundabouts?

A quick Google points to the road camber...

Odd that I've never experienced it before though. Perhaps pr3s are better at withstanding it? 🤔

Nothing odd about it, same happens to my bikes too, worse of all is my CB250 with the Bridgestone BT45. Still handles okay but looks nasty and could attract the attention of the pigs.

New bike.

Both forks are setup the same?

My Bridgestones (can't remember which ones) went like that, very noticeable. Garage said they were renowned for it. Haven't noticed the same on my PR3's though, but I'm guessing PR3's are hardier and less performance focused than the PR4's?

I don't believe the 'road camber' explanation because the angle is so small (unless you're trundling along the Daytona banking ). The 'roundabouts' argument makes more sense to me, but what do you think about this explanation from the USA?

Why did no one suggest frame/wheel alignment yet?

And the road camber will wear one side more than the other if you use those mental camber roads.

He is likely suggesting rear wheel alignment rather than a bent frame.

If your rear wheel isn't aligned to the rest of the chassis and front wheel, I would imagine that to have an effect on tyre wear, both at the front and the rear

This seems to have happened to several people that I know who have had a Michelin PR4 fitted to the front of their bikes,a Suzuki V-Strom 1000 and a Yamaha R1-5PW in particular.In both cases they wore like a new £1 coin with abrupt edges.This I was told was quite disconcerting when leaning into corners and especially in the wet.

As for the wear characteristics between the PR3 and the PR4 I can only vouch for the PR3 wearing more evenly.I fitted one to the front of not only my Exup1000 but also the FJ1200.Both have worn very evenly,the FJ having covered around 3,000 miles around the Continent in 2016 and around 2,400 miles around France last year,with about 1,500 miles being ridden when back in the UK.The front tyre still looks good for a few thousand miles more.

From my friends experience with the PR4 front I would be looking in the future to try the newer Road 5 instead

+1 more for uneven PR4 front wear on one side (will check which side).
I did refurb the forks so I'll never know if that cured it.
