Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A ExtremeContact Sport
Pros
- Exceptional dry and wet traction with high confidence in the rain
- High value for money compared to primary competitors like Michelin
- Quiet and comfortable ride quality for an ultra-high-performance tire
Cons
- Softer sidewalls leading to a slight delay or lack of immediate steering feedback and precision
- Requires a brief warm-up period in colder temperatures, sometimes causing temporary vibrations
- Stiff ride over sharp road imperfections noted by some users
Tire B G-MAX RS
Pros
- Outstanding price-to-performance ratio compared to premium brands
- Strong dry and wet weather traction and hydroplaning resistance
- Quiet and comfortable ride quality for a performance tire
Cons
- Softer sidewalls can lead to some squirm or less crisp steering response during hard cornering
- Prone to temporary flat-spotting or vibration when sitting overnight in cooler weather
- Unpredictable or slippery performance if driven in cold temperatures below 45 degrees Fahrenheit

Tire A
Continental ExtremeContact Sport
We haven't collected enough community discussion about this tire yet.
Tire B
Positive
General G-MAX RS
Community sentiment toward the General G-MAX RS is broadly positive, with users frequently praising its exceptional value and strong dry and wet traction as a budget-friendly ultra-high-performance summer tire. While often favorably compared against premium alternatives like the Michelin Pilot Sport 4S or Firestone Indy 500, some owners note compromises including elevated road noise and occasional handling inconsistencies on specific sports car platforms.

“Darn, no 255/45R18, so I won't get to try these on the E38 for my next set of summers (it'll probably be the Kumho Ecsta Sport or Bridgestone Potenza Sport instead, but Tire Rack no longer has the Bridgestones in 255/45 even though they're still listed on the Bridgestone site). It seems like tire availability in that size is dropping way off. Conti dropped it in the ECS02 and discontinued the General G-Max RS in that size, now it's gone in the Indy 500 V2. So to run either of those tires I'd have to buy different front wheels and move to square 275s instead of the 255/275 stagger I'm running now. PS4S comes in a 255/45, but I'd have to move up to 285/40 in the rear (from 275/40) and they're rather expensive.”

“I'm going to get the Firestones or General G-MAX RS tires when the previous owners Michelin all-season tires wear out. I want a summer performance tire. Leaning towards the Firestone since they have better dry performance than the Generals. The Generals do better in the wet according to the performance test they both were in.”

“I, too, read the comments here about the G-Max being a favorable option, and got the G-Max tires for my stock 996tt wheels and they lasted on my car for 1 or 2 days since they handled so poorly, and PSM didn't like them. There's a fun set of turns on my way to work that I can do up to 65mph with no PSM intervention on Yoko AD08R tires. The G-Max tires could hardly go 45 without PSM getting upset, and the car felt very nervous/unsteady. Maybe they need a long break-in period? I don't know, but boy they transformed my FEAL suspensioned 996tt into what felt like I was driving a VW Thing. Thankfully Discount Tire has a guarantee so I had them removed and replaced with the AD08R tires, which are fantastic (albeit more expensive).”

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.
