Maxtrek TREK M900 295/40 R21 Mercedes Benz GL 350 CDI 3,107 miles March 11, 2025
Installed on GL 350 , rugged looking tire , first time using this brand.

If the manufacturer improvise the road noise conditions on dry highway surfaces at both low and high speeds not exceeding 120km.

This tire would be a great selling point , cabin noise decibels are through the roof.

Especially for a MB GL 350 fitted with air ride suspension, it feels like we’re constantly driving through a construction zone.

Gonna sell these and buy something closer to Hankook, Continental, etc

Got them installed brand new , we drove a combined 40 + hrs and 3106.856 miles.

It’s noisy and appalling, sounds like my bearings are all bad, which is definitely not the situation.

Got me second guessing myself.

Quite a nice budget tire. I have to say the dry grip is outstanding. Wet grip is satisfactory. Road feedback is good. Ride comfort is OK for a 21'.
Unfortunately when it comes to snow/ice, the tire has pathetic performance. I've been better off with permium SUMMER tires... The vehicle is barely controllable and in fact scary to drive.

I have these on my Porsche Cayenne 3.0 diesel and they are fine. I don't have a heavy foot and tend to have a chilled out driving style. Driven approx 15,000 miles in last 12 months and can't fault them. Will be buying again especially at 85 per tyre fitted.

Pirelli Scorpion Zero 295/40 R21 Mercedes Benz Mercedes GL 500 January 9, 2016
I have a mercedes GL, with 15000 miles on the scorpions. In the last 5000 miles they were always out of balance, numerous times they were re blanced, but still there was a vibration. Finally, I noted the sidewall breaking down, with some rubber falling off , about 4 cm in diam. This had developed on 3 tyres, one on the outside (the one i first notice) and the other two on the inside. NO, I would definately not recommend them for this vehicle again. The tyres were always properly inflated.
