Evening Bazzer; I suspect you'll only ever find a marginal comfort difference and there'll be a trade off, longevity or grip, possibly both. FWW my CRV came with virtually new Goodyeaar Efficient Grips. They never impressed, especially in the wet, and the first time I drove in snow was enough for me to get rid of them prematurely. I chose Continental All Season Contacts; not cheap but at about £250 more for four than the cheapest cheap and nasties, not that much for improved braking, steering, handling, etc. Mine have clocked up about 20k and still have plenty of life left in them. If there's a false economy, it's cheap tyres!
