Cross-posting from other Benz forums -- wanted to find if there was any similar experience with these tires.

##################

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 ?

tires replaced by TOYO

Toyo Customer Service had me demount the tires and ship them back to them. Upon receipt, they would replace them (2 FRONTs) no questions asked.

Tires were demounted on 17-OCT-03, and sent to Toyo -- received 27-OCT-03. They paid for all shipment.

Update: replacement T1-S PROXES tires (2) arrived TODAY (18-NOV-03). Its GREAT to see a vendor standing behind their products. [8D]
