Testing the Tires: BFGoodrich g-Force Series

When I started racing in the Global Mazda MX-5 Cup Series last year, that meant switching to the spec BFGoodrich tires required for the series. Not only had I never run on the g-Force Slick and g-Force Wet tires before, but it was also my first time using BFGoodrich tires at all!

g-Force Slick
One of the advantages of the g-Force Slick is how quickly it comes up to temperature. Some tires need a solid two laps before you can really trust them to stick, but the g-Force tires only need one very efficient lap of scrubbing. You can get up to speed faster, which means more valuable track time.

And once you are up to speed, you can trust the tires to stay consistent, which is vital for a race.

What really amazed me was how much use you can get out of a set of tires. We put one set through 15 heat cycles between Watkins Glen and Road America last year, but we were still able to get our basic setup done for both tracks. Once we get a new set of stickers mounted when we return to Watkins Glen this year, we should only need to change the cross-weight to finalize the setup of my GB Racing/Racing Analytics MX-5.

The BFGoodrich g-Force Slicks perform well in the heat, too. All slicks like cooler temperatures—ambient temps in the high 70s are a sweet spot for race tires. But at Road Atlanta last year, we went out for qualifying on a track that was over 110 degrees! The tires were on point and had a really good grip level despite the heat.

g-Force Wet
The g-Force Slicks might be good on a greasy track, but if it starts to rain on top of that, things can get slippery quickly. That’s when it’s time to bring out the BFGoodrich g-Force Wet, which is hands-down the best rain tire I’ve ever been on.

The rain tire is super soft, so you can fold back the tread with your hand. That means you have more grip on the track because the tread is able to move the water around efficiently.

The first time I ran on the BFGoodrich Wet tires was at Watkins Glen—I was on slicks when the rain started, and that track is not a place where you want to be sliding in the wet! I pitted for rains, and when I went back out I immediately had so much confidence in my tires.

Trackside Support
The BFGoodrich tire techs are at the track to help you, so if you’re running their tires, don’t be afraid to ask them about things like proper tire pressures. Those guys were amazing at Indy this year. When it became obvious we’d have a rain race, they worked to get rains mounted quickly so everyone could be on the starting grid.

In short, trust the BFGoodrich g-Force tires. Even if it’s just your second lap on the slicks, don’t be afraid to give it your all. You can put your confidence in this slick because it has such good grip. And if it’s raining, you can still turn competitive laps knowing your g-Force Wet tires are going to keep you in the right place.
