Odd wear on my front tyre.

<< < (2/2)

I'm currently running 44psi in the front, 46psi in the rear...
I think some of the initial abnormal wear (front & rear) was due to the dodgy tyre pressure gauge I'd been using which, after checking with other tyre gauges, was found to be overstating pressures by a couple of psi.

My advice is to buy a decent gauge and certainly don't rely on the gauges at your typical petrol station as they can be notoriously inaccurate...  :thumbs

I'm another advocate for running higher pressures than is recommended. It was this very topic that saw me discover the old Yahoo ST group back in 2009ish. Scalloping was something I had not experienced on any of my previous bikes. I think the OEM's were Bridgestones and the front was changed at 8k and the rear at 12k with terrible scalloping. Through an excellent explanation from a member I then used to run 45-46 in both front and rear. The best I got was 28k out of a set of Michelin PR4's.

Another thing to consider when adjusting tire pressures is the combined weight of rider, pillion, cargo any accessories.

The lesson for me was that low tyre pressures contribute to severe scalloping on the sides, so I'd suggest bumping up your pressures.  From memory a lot of the ST folk are running with 42 and 44 psi.

Yeah but...

Doesn't that lead to early tyre centre wearing?  I can easily visualise why it would reduce scalloping, but mine tend to go in the centre first, using the common 42/42 (290kpa).  I do get mild scalloping.  I frequently have a pillion on the ST, usually Mrs Biggles.

Good point, JD!  :thumbs

Which is why from day one I'd ran 44psi in the rear but due to my dodgy gauge I was probably actually only running 42-ish which, with Sue on the back along with my not inconsiderable weight would have meant we were running the tyre under-inflated...  :||||
