Dunlop Grandtrek ST20 225/65 R18 Nissan Murano 35,000 miles December 1, 2019
Had these tires original on our 2009 Murano. changed them after 55000km. Bought Bridgestone Euporia 890 and will go back to these tires. Only problem with them was that the sides are wearing much quicker then the rest of the tire. Will try with a slightly higher pressure to see if that make some difference.

Lassa Competus HP 225/65 R18 Volvo XC60 600 miles March 10, 2018
Was doubious at first but had these fitted as I was told they are basically Bridgestone tires. Up to now, they have been excellent and only the wear has yet to be proven. Up to now, I would recommend considering a 'known brand' could cost you half as much again, if not more.

Great in snow, very low road noise, look the part, great grip in the wet, don't impact on mpg and, stop just as good as the old P Scorpions that came off.

Dunlop Grandtrek ST30 225/65 R18 Honda CRV 32,000 miles March 23, 2014
Great in all weather conditions including deep snow but they wear down quickly on my Honda CRV. Car has only done a steady 32000 miles but have had 2 sets on front and one set on rear. Have now got Michelin Latitude Tour HP on the rear and am going to have these al;so fitted on the front.

good value tire, good in the wet, a little prone to flat spots when left for a while, they wear well. Side wall quite thin does not protect rims at all.
