Stop in 109 Feet or Slide for 126? The Real Truth About Honda Civic Si Summer Tires vs. All-Seasons
You know that feeling when you’re carving through a curve and the Civic Si just grips the road like it’s on rails—until you hit a cold morning and suddenly, it feels like you’re driving on hockey pucks.
TL;DR
Summer tires on the Honda Civic Si offer dramatically shorter stopping distances and much higher cornering grip compared to all-season tires, but they wear out faster and become dangerous in cold weather. All-season tires last longer and work year-round, but they give up about 17 feet of stopping distance from 70 mph and can’t match the Si’s full performance potential. The $200 factory summer tire option is a steal, but only if you live in a warm climate or are willing to buy a second set of tires for winter.
Key Takeaways
- Summer tires stop 17 feet shorter from 70 mph than all-seasons on the Civic Si—that’s more than a full car length.
- Skidpad grip drops from 0.97 g to just 0.88 g when you switch from summer to all-season tires.
- All-season tires have higher treadwear ratings (around 560) compared to summer tires, meaning they last longer.
- The $200 High-Performance Tire (HPT) option is one of the best value upgrades you can make—if you understand the trade-offs.
- Summer tires lose grip below 40-45°F and can become dangerously slippery in cold weather.
- The Goodyear Eagle F1 Asymmetric 2 summer tires that come with the HPT package are the same tires used on Ferrari California and Porsche models.
The Real Numbers: Stopping Distance and Grip
Let’s get right to the numbers that matter. Car and Driver tested the 2017 Civic Si with both summer and all-season tires, and the results are eye-opening.
The summer-tire-equipped Si stopped from 70 mph a full 17 feet shorter than the all-season version . That’s more than the length of a Honda Civic itself. In a panic stop, 17 feet could be the difference between stopping before an obstacle and plowing into it.
The skidpad numbers tell a similar story. The summer-tire Si pulled an impressive 0.97 g of lateral grip, while the all-season car managed just 0.88 g . That’s a noticeable difference when you’re pushing hard through a cloverleaf or on-ramp.
MotorTrend’s testing of the 2013 Civic Si with optional Michelin Pilot Sport 3 summer tires found a stopping distance of just 109 feet from 60 mph—making it the best-stopping Si they’d ever tested .
Here’s a quick comparison of the key numbers:
| Test | Summer Tires | All-Season Tires | Difference |
|---|---|---|---|
| 70-0 mph Braking | Shorter by 17 ft | Longer by 17 ft | 17 feet |
| Skidpad Grip | 0.97 g | 0.88 g | 0.09 g |
| 0-60 mph | 6.3 seconds | 6.7 seconds | 0.4 seconds |
Treadwear Reality: How Long Do They Last?
Here’s where things get interesting. All-season tires are designed to last. The Goodyear Eagle Sport all-season tires that came on many Civic Si models have a treadwear rating of 560 . That’s a pretty high number, meaning you can expect them to go the distance.
Grassroots Motorsports put those all-season Goodyears through four track events and measured only 1/32nd of an inch of wear . The tires aged well and didn’t get greasy even during 20-minute sessions. That’s impressive for a tire that isn’t even designed for track use.
Summer tires, on the other hand, typically wear faster. The softer rubber compounds that give them their grip also mean they’re not built to last as long. Most summer performance tires don’t even come with a treadwear warranty, while all-season tires often come with 50,000-mile or longer warranties .
The trade-off is clear: all-seasons last longer and cost less per mile, but you’re giving up performance .
The $200 Question: Is the HPT Option Worth It?
Honda offers the High-Performance Tire option on many Civic Si models for just $200. That swaps the standard all-season Goodyear Eagle Sports for Goodyear Eagle F1 Asymmetric 2 summer tires .
Here’s the catch: the Eagle F1 Asymmetric 2 is a serious tire. It’s the same tire that comes on Ferrari California, Audi Q7, and some Porsche models . For $200, you’re getting a massive performance upgrade.
But if you live anywhere with real winters, that $200 tire upgrade turns into a much bigger investment. You’ll need a second set of wheels and tires for the cold months. That’s around $700 for tires and $1,200 for OEM wheels . Suddenly, your $200 option is really a $2,000 commitment.
The smart approach for many owners? Skip the HPT option, and when the factory all-seasons wear out, invest in a set of grippy performance all-seasons . You get better grip than the stock all-seasons without having to manage two sets of tires.
The Cold Weather Warning
This is the most important thing to understand about summer tires: they are not safe in cold weather.
When temperatures drop below 40-45°F, summer tire rubber hardens and loses grip dramatically. The same tire that sticks like glue on a warm summer day becomes dangerously slippery on a cold morning. Even if there’s no snow or ice, the compound just doesn’t work at low temperatures.
That’s why Honda offers all-season tires as standard equipment on the Civic Si. They want the car to work for everyone, regardless of climate. The summer tire option is for enthusiasts in warm climates or those willing to manage two sets .
Real-World Owner Experience
Tyre Reviews data shows Civic Si owners rate their tires across several categories. The Michelin Pilot Sport AS 3+ (an all-season) scores 82% for dry grip and 88% for wet grip, while owners report treadwear ratings around 78% satisfaction . This suggests owners find a good balance of grip and longevity.
One Civic Si owner noted that performance all-seasons like the Continental ExtremeContact DWS 06 Plus feel great in most conditions but become noticeable in temperatures below 20°F .
The Verdict: Which Should You Choose?
If you live in a warm climate (Florida, Texas, Southern California) and you enjoy driving your Si aggressively, get the summer tires. The $200 upgrade is a bargain for the performance you gain. The shorter stopping distance alone could save you from an accident.
If you live in a region with real winters (the Northeast, Midwest, or anywhere that sees snow and freezing temps), stick with all-seasons or plan to buy a second set of winter wheels and tires. The summer tires are essentially unusable in cold weather, and swapping them out seasonally gets expensive and inconvenient.
If you’re somewhere in between and want one set that does everything well, skip the HPT option and later upgrade to premium performance all-seasons. You won’t match the grip of summer tires on a hot day, but you’ll have a tire that works year-round and still lets you have fun.
