Thanks. Did you use the same mounting hardware for the new wheels?
Hi, sorry for delay, i just replaced the 8mm stainless bolts and nylock nuts with washers all from toolstation, bolts are 8mm x 60mm and have a shoulder (no thread part) that the nylon wheels run on.

So the wheels arrived today 🙂
They are a bit narrower tread than the existing ones, although the diameter is correct. I think they will ok.
So the first job was to remove the bolts holder on the existing wheels. I had already primed with Plus Gas and added some more for good measure. Some of the bolts are corroded, so I started with a non-corroded one. Using a spanner, I released the nut and got it moving. But then it stopped. The problem is that the whole bolt rotates freely. Ideally I would have liked to use a screwdriver in the bolt head to stop this rotation while working the nut with the spanner. But the bolts have a smooth domed head - no slot!!!
I could try and grip the bolt with pliers, but what would likely damage the bolt thread and I'd never get the nut off.
Any suggestions?
I know its late but i swapped out all of my early pulsar wheels for new ones, then had to replace those because of flat spotting, went for these in the end. cheap as chips and no problems.

Just a little tip when using stainless steel nuts and bolts etc, use a drop of grease on the threads because the thread will gall up without it and prevent from tightening or loosening
