The time has finally come to replace my standard 17" wheels, with Vredestein "Wintrac Xtreme" tyres on (review in the review section), with Summer tyres on the "Sigma" 18" alloys that I bought from HH nearly a year ago... My dilemma is this - the required size (225/45ZR 18 95Y) seems quite limiting in terms of what is available. I don't want to spend a fortune and have 4 options from the online source that I plan to use (Oponeo, who were great with the last set so will use again). I would welcome opinions on: Nexen N8000 - available at £80 each. Well reviewed online, but I've never really heard of them. Worth a punt? Hankook Ventus S-1 Ezo2 K-117 at £119 each. Again, have seen some good reviews, these feel like the preferred option at the moment, as at least I've heard of them. Vredestein Ultrac Sessanta at £128 each. A good review on here already... Yokohama ADVAN Sport V103 at £151 each. Don't really want to spend that much, but am willing to be convinced that it is worth it! Bridgestone, Continental, Michelin all even more expensive than the Yokos (!!), so will give them a miss. And one final question...the instructions with the wheels are clear that I must use 225/45ZR 18 95Y tyres. But I'm a bit confused - what does the "ZR" refer to and what does the "Y" refer to, as I thought they both referred to speed rating? There aren't many tyres that have that EXACT description - but there are plenty that omit the "ZR" part (well, have "R" instead). Thanks in advance! I know tyres always spark some debate, and I'd really welcome opinions...should add that 80% of my driving is motorway.
