“Advice on new tyres So my car got stolen (RIP) and I bought a 16' MB c200d with rears 245/40r18 Its time to change them and I don't know what to do. A/S are not needed because snow is very rare in central Spain. Winter temperatures range between 0-10°C and summer range from 30 to 40. As I drive 25-30000 km per year I especially value wet performance and durability (Minimum 35-40000 km). The problem is, the tyres that would fit perfectlly to me are not available in this size (GY efficient grip performance 2 -best tyres i've ever had- and Michelin Primacy 5). What i've seen is Firestone (both roadhawk 2 and roadhawk sport), continental PC7, GY assy 6, Michelin PS5, bridgestone T6, Dunlop sport TG, kormoran/tigar/Taurus summer 2, nexen sport, hancook (Ventus evo 137 and Ventus prime 4) and kumho ps72. Even though It would be nice to save some money, i'm worried about losing rear grip when wet (its my first rwd) so its not important. What would you pick? Read more”

“17" Goodyear efficient grip performance 2 small leak Hi, On my VW Touran 2019, 1.5 TSI, 17" alu oem wheels I have set Goodyear efficient grip performance 2 . There is a small leak lets say the pressure goes fro m 2.5psi to 2 psi in approx 7-10 days. The VW tpms warns me usually every 2-3 weeks. Those are summer tires, I just removed them for swapping with winter ones and I haven't cleaned them yet. They are quite dirty at the moment. The leaking one, pictured, was in the front this year, I switch them front/back every year. In my opinion it can do one last year (next summer) in the back. How would you fix the leak? I read those slime sprays damages the tire internally over time, but them its really approaching end of life fast in my opinion... I did visual inspection, I really dont see anything except maybe 1or two very tiny mark that could have been a nail puncture or something but its nothing sure... Maybe soap+ water? Thanks for hints. Ps: I have the tool somewhere for the indicator measurement, I cant find it right now.”

“17" Goodyear efficient grip performance 2 small leak identified Hi, On my VW Touran 2019, 1.5 TSI, 17" alu oem wheels I have set Goodyear efficient grip performance 2 . There is a small leak lets say the pressure goes fro m 2.5psi to 2 psi in approx 7-10 days. The VW tpms warns me usually every 2-3 weeks. Im posting a new topic as I cant seem to upload pictures on the other one... Thanks to some help here I found the leak. See the pictures. I have no idea what is that roundish shape it seems smooth/rubbery and the hole clearly come from inside it. What now? Slime bottle? Glue? Or this thing that goes inside like a tire repair kit with the kind of rope thingy? Thanks!”

“Hankook ventus prime 4 VS Goodyear efficientgrip performance 2 I cannot decide between these two tires for ages now. Customer reviews seem all over the place. I drive a tuned volkswagen polo mk6 2020. I need something that inspires confidence for spirited driving in corners with good stability, mainly dry handling and braking but also relatively comfortable. So far I've learned that the goodyear is more comfortable, better in the wet, better at braking but extremely lousy in handling because of the soft sidewalls. Can someone that has used the EGP2 confirm those claims or are they exaggerating. Base spec polos are known for a harsh ride and I live in the balkans. The roads are full of potholes and sometimes you can't even drive around them. specs: 195/55R16 87V”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
