I have been using Prestivo tyres on the front of my Picasso for 20k miles on a 185/65/15 and alas mrs SD hit a pot hole and blew the tyre out. I checked the warrentee and found this below

Returned to the tyre dealer, no quibble replacement tyre £15
These tyres ar £56 each which is £35 less than equivelant mitcheline’s (which at 20k are knackered) and should be good for 40k+ and I have never had any grip issues with them so perhaps Cheap tyres can be good
