Front tire is now about 6 months old.

So far I am satisfied with the motorcycle tire on the rear wheel.

The tire has been on it for almost 2 weeks now and so far so good. At first I had inflated it manually to try it out carefully. I noticed that it was cycling hard and couldn't get up to speed. I saw that it was at 1.5 bar and I further inflated it to just over 2 bar. Now the cycling is nice and smooth again.

I have reported the situation with the front tire to RAD and am waiting for a response. In the near future I will check the front wheel regularly and replace it if in doubt.

This is my first topic here. Various people have already responded to the tire discussion of the Radwagon 4 on various topics. I have also taken advantage of this and would like to thank everyone for the information.
I would like to share my experience with the tires of the Radwagon 4 that we have been using since the beginning of the year.

I used the Tannus Armor inner tube armor on both tires.
This caused a leak at the rear wheel due to a shift of the anti-puncture foam. I took out the foam, taped it and put it back again. But because the band is slightly narrower, it cannot have too much stretch. I later inflated both tires to 3 bar. And then the rear tire collapsed after use.
I'm starting to see cracks on the front tire. Hopefully that still goes well.

I have replaced the rear wheel inner tube and tire with a alternative brand. And I will pump both tires to about 2 bar. I don't think higher pressure goes well.

I may want to replace the front wheel inner and outer tire later as a precaution.
