Viking PT5

[Terratoss]

Hi all, I got these viking PT5 since feb 2018. Have been using them now for about 16000km.

 

When I 1st gotten the tyres, I kept the pressure(cold) at front(~37psi), back(~35psi). The road contact seems ok when I go over e.g. dusty areas, wet areas, I do see front and back tyres have full/good contact with the sand/water marks on the tyres.

 

I observed something about the tyres after my 1st 10k km rotation. It seems like the back tyres aren't really contacting the road fully at the shoulder areas about 1-2cm from side wall.

Previously, when tyres were new, at 35psi(cold), its was alright. Now, it seems like it is over-inflated. I tried reducing to 33psi(cold), it looks slightly better but not 100%.

 

Any other users have similar experience to mine?
