I have R888R's and my installer raised concerns about the asymmetrical tread pattern also. He insisted that I had purchased 4 "passenger side" tires. I called Toyo and they confirmed there is only one tread pattern and it will appear to be reversed from side to side due to mounting. The important mounting step is to be sure the large tread blocks are on the outside and the narrow blocks are inside. The tires must be mounted with the "outside" lettering facing out according to the Toyo rep I spoke to

They are asymmetrical. Same deal with NT01's.

They are asymmetrical so they will not look the same from the left side of the car and the right side of the car. The tires are marked “outside” on the sidewall. Your installer did not follow the directions.

Thanks for the review! Planning to get a set of these when I need to replace the MPSS'. Seems like they should definitely be capable of hooking in my HCIE setup. MPSS' are nice, but not great in terms of hooking when nearing 600 rwhp.

What sizes would you all recommend for stock Z06 wheels? I'm interested in stepping up to the 345s in the rear, but not if it will have a detrimental effect anywhere.

Frankie.. do the 345/30/19's and don't look back... I am running the 4S's on my stockers (stock sizes) on all 4 corners. I need some rear tire tires for traction... Car corners awesome... but tires spin in 2nd pretty bad...

Would you also go with 285s in the front to accommodate for the 345s in the rear? What size exactly would be optimal for front tires if going 345/30/19 in the back? Thanks bud!

I am going to go with these next on mine. I have MPSS on the front, and Sport Cup on the rear, and the care handles and rides great, no road noise, BUT, traction is super limited at 620/550. I thought the Cups would hold better, but I have lost traction at 80+ with a 2-3rd shift. It will hold 1 and 2nd if i gently lay into it, but any punch of the throttle and they blister. This is on heavy ZR1 repros, and I just picked up a set of super light Rennen Concave wheels that weigh much less than the repros. Mine is not a dd, just a once a month (if I'm lucky) weekend warrior.

I run the Toyos on my '09 ZR1. Absolutely LOVE them. The only complaint I have is that they're a little noisy. 285 fronts, 345 rears.
