Good to hear. Just make sure he shaves down the tabs that the fender liner screws into before he rolls them. There's an extremely high chance you're going to get dimples (in the front at least), but this should help lessen that.

 

I'll try to remember to say that to him. He's just gonna roll the rear fenders. There's no need to roll the front 'cause I'm happy with it as is.

Thanks for your interest in this and your advices.

Problems keep on coming (or existing).

The car stood still from saturday evening till monday morning when I left for work and the rear wheel that has had leaks before was flat.
I got it fixed and it appears it leaks from the rim bolts now. Not much but so that it empties itself in just over a day of standing still. Sucks *****!

Yesterday I checked the pressure at around 5pm and it was 3,4bar and today in the morning it was 3,1-3,2bar.

 

Check again at 5pm because hot air expands and will be higher psi than cold air. If it's been sitting in the sun all day then the tire reading will definitely be higher than right in the morning after a cold night.

 

The tire was just put on so it hadn't been sitting in the sun all day. But yeah, that could have been one explanation.
Yesterday I sprayed in the tire a can of tire sealant similar to this

and it didn't help either because the pressure had still dropped from 3,3bar to 3,1bar over night.
I thought that would've helped seal the little cracks it's leaking from.

I just have to go with it and check the pressure every day through the summer and dismantle the wheel in the winter when I have nothing else to do.
