At least a couple guys here are. I'm sure they can provide more info., but I've driven DAVESNELLING's RWD '35 with the Toyos and done some G-tech runs. I didn't notice much difference in ride quality, but did notice more tire noise. I didn't take any hard corners, so can't comment on that aspect, but to me, they actually seemed to have a bit less grip than the stock tires in a straight line. I got a fair amount of wheelspin doing G-tech runs in his stock vehicle, while I got much less in my modded, faster vehicle on stock tires. The Toyos do have a considerably higher treadwear rating than the stock tires.
I have them since November.They are quiet,work very well in snow,v good in rain,not quite excellent-better than stock though,.
I have 265/45x20 did this for a reason on 20x9 rims.
If you can wait closer to the fall or later do.Give full thread depth for their first winter and wear off some for spring hard driving...this is a block thread and deep so some wear will improve handling
