Had a close call with the 18" TOYO T1-S Proxes on my 93 W124 coupe.

Setup: Running a +3 18/18 fitment using 18-225-40 TOYO T1-S Proxes
- nominal tire pressures 34 F / 37 R
- approx tire mileage < 14000 miles

While running on a Interstate I-94 this weekend, had an incident with the LEFT FRONT (driver side) tire.

A section of tread (about 1/2 wide) had separated from the tire, just about where the sidewall and the main tread intersect. Tire did not fail, no pressure loss (we have SmartTire tire management system)... the "flapping" section caused a loud sound, which alerted us to the problem.

Section that separated was pretty deep -- inner (steel?) fibers were exposed and tread was beginning to separate from the sidewall.

As far as we can tell, there were no punctures or obvious perforations on the sidewall. It looks like tire failure, possibly due to a manufacturing/fabrication problem. Tire was correctly inflated, with no significant pressure or temperature variance.

Has anyone else encountered problems with TOYO T1-S Proxes ?
