Set of 4 Nexen N Fera SU1 255/40R18 99Y XL Tires Fits: 2011-20 Mercedes-Benz SL550 Base, 2004-06 Mercedes-Benz SL500 Base

I'm fairly obsessed with tires, they're the only part of your car that touches the road so they're pretty darn important. I've always been a "the grass is greener on the other side" person with tires, always trying new ones when my tires wear out. So when my car's stock tires wore down I needed some new ones and I started shopping for summer tires, since I live in Texas and is always (basically) summer. I settled in these N'fera SU1 tires because they included a mileage warranty AND road hazard at a great price. I'm very glad that I did, as they've served me very well. They handle well, offering notably more grip than the stock all seasons, and they're quieter than their predecessors as well. They lasted about 30,000 miles for me, which I was satisfied with since I drive on them fairly hard - AND that included a track day at a circuit. My commute is about 65 miles a day, and they've been great for that too. Thanks to all these strengths and good performance, they are now the only tire I've bought twice. I felt like no other tire would be able to offer as much for the price.

I have 20" wheels with low profile tires on an Audi A6 S-Line, and the Pirelli's PZero that the car came with offered good road feedback but were getting increasingly hard, uncomfortable and noisy as they started to get older. So when they finally went, I wanted to replace them with something more quiet and comfortable, but also good in the wet and with a decent handling level. The NFera SU1 is exactly the type of tyre i was looking for. Positives: very comfortable, extremely quiet for a 255/35/R20 tyre (Nexen says 68dB), good wet grip, great price Negatives: not so good road feedback and dry braking (compared to the PZero), handling is average The wear level is nothing special, it wears a bit faster than the PZero, because the SU1 is a softer tyre, but not by much. I have done about 12k miles and they seem to be about half their original thread height.
