They have crushed walnut shells embedded in the rubber compound for extra grip and I'm very pleased with them.
That exact same thing happened to my 2014 CX-5 GT. Toyo's warranty is no good, they ask you to ship the tires for them to evaluate warranty claims, ended up throwing them out and getting Pirellis.
BMW road force balanced them and they were perfect... my savings were about $750 after getting them to do the balancing.
We sold these at the tire center a I worked at. We rarely had a repeat customer get them twice. They always upgraded to the Toyo MT, and that wasn't us being pushy salesmen. We always asked why, and the regular complaints were the loud drone from the tires at freeway speeds and they didn't last for jack under the heavier trucks. 40K miles was on the high side of things.
I bought [Toyo Observe GSi5](http://www.toyotires.ca/tire/pattern/observe-gsi5) for my car, I've no problems with them after three winters, driven country roads without slippage either.
I wanted a cool looking and well working tire. Read several reviews and decided to go a mid-way in price/performance depending on weather conditions in Latvia in summer, so today I got a new set of Toyo Proxes T1R for the summer season
I have about 10K on my '13 TTS. Just changed over to my snows and the original Toyos still look near brand new. Front and back looked about the same in wear.
I'm fixing to put the 5th pair of tires on the rear......and the fronts aren't going to be too far behind. The car has only 32,000 miles on it. Toyo's. They are wearing flat, no cupping, but wearing fast.
Everyone stretched Toyo T1Rs because they best UHP but also very stretchable so best of both world what with being dope stance PLUS late night touge runs will win every time.
I can't input on the stretch, I am running the proxes 4 , I'm running a 19x8.5 with a 215-35 so my stretch is not close to what yours will be but I can tell you these tires are super loud with tons of road noise.
