According to picture observation. Arrowhead indicates the place has flaw apparently, still tire decorative pattern also wears away not little. Demonstrative tire has a few years of histories. It is ageing phenomenon for certain. Tire is general the expiration period 3 5 years one.
Resemble this circumstance, give you a few proposals. See deepness of tire decorative pattern whether be not worth 1.6mm, if be not worth, must change.
Especially the summer was gotten on for, air temperature is elevatory, reckon crackle still can greaten. If do not run high speed, still can use period of time. Had better change two before embryo. Compare insurance so.
If want to run high speed, a person of extraordinary powers was changed forthwith. 4 embryoes otherwise how many money. If become flat, damage is big. Because of high speed travel, tire warms up fast, heat bilges cold shrink, the tire of ageing becomes flat more easily.
Do not joke with tire, tire cannot sportive. Safe drive a vehicle is the mainest!
