I dont believe in them "ratings"
The toyo T1R was designed to improve dry and wet handling, getting classed on some websites as "Exceptional Grip In the Wet". They are rated as an E for wet weather, which is a load of crap as i have driven in the wet with them loads of times and a little too fast a few times but they never had any problems in the wet, even when going round corners fast in the wet they were great.
Plus demon tweeks have got them back in stock in 14's for £57 a tyre.
