It's more an issue of people accepting that others are allowed to have opinions. If you read the many threads there is a bit of an underlying trend that the Acceleras are good, inexpensive, but maybe not the ultimate tyre for 19" wheels.
It doesn't look good to people who are searching for info to have 10 pages of circular argument to wade through and there is a tendency to just look elsewhere when faced with it. I probably should have toned down the 'pig sick' comment a little but I'm not going to go back and edit a previous post after someone replies. I do read these threads as if there is a decent alternative which saves me cash I'd probably plump for it. If I had a TI on 19"s I'd probably fit them myself to see.
There are a number of subjects across car forums that provoke such debate - fuel additives etc. or look on any RX-8 forum for hot start/compression/mpg/engine oils for similar veins.
Make something idiot proof and someone will only go and build a better idiot...
