A lot of people like them. I’ve spent time with both, and I like both tires. For the price of the venoms, if I had to do it again, I would just buy the venom‘s. They are slightly louder than the Toyos I have in my signature and they suck just a tiny bit more mpg than the Toyos (0.4mpg over 6 tanks on the hemi). They are so similar though that the cost savings makes it worth it to me for the venoms. The big downside would be getting warranty on them, so make sure you buy from someone like discount tire or tire rack and get some kind of extended warranty or non-manufacturer warranty.
I may actually sell the wheel and tire set up in my signature pretty soon.
