Vehicle slips terribly even after installing Winter Tires on Q7
I have installed Dunlop GRANDTREK WT M3 P275/45R20 XL - 110V Winter Tires on my Q7 but the vehicle slips terribly even in little snow. What should be the tire PSI for one passenger and with full load? I have set it to 36.
Also the Tires makes a lot of noise. (

Re: Vehicle slips terribly even after installing Winter Tires on
I'd suggest you set the tire pressure as recommended in the vehicle operating manual. Reducing tire pressure should improve grip. I think 36 is high, but I have a Q5, and I run 33 summer and 29 winter out in the mountains.
In my opinion the winter tire is always noisier than the summer tire because the tread pattern is more coarse. The chunky parts of the tire are called "lugs" and as the tire rotates and the pattern hits the road surface it generates more noise. You can search the web for relative tire noise and compare noise levels.
