My reviews of tyres on my GTV:
Budget rubber it came with
= poor wet handling and dry grip Average
Vredestein Ultra Sesanta
= Very good in wet, good in dry, good in snow. Wear = 8k
= Good in Wet, Okay in dry, poor in snow. Wear = 11k
= Very good in wet, Great in dry, Havent been on snow on these boots, noisey too.
= Great in Wet, Great in dry, have not been in snow yet, alot quieter on the road than all of above.
For me it would have to be Bridgestone S001 or the Vredestein Ultrac Sesanta's.
Remember never skimp on tyres, only thing connecting you with the road surface!!
