The G-Force Sport is BFGoodrich’s moderately aggressive summer tire. The Tire Rack classifies it as an “Ultra High Performance” tire, grouping it with the Bridgestone Potenza RE750, the Dunlop Direzza, and the Yokohama AVS ES100. At $75 (from Tire Rack) for a 195/50/15, it’s middle of the pack in terms of price. For your money, you get a tire with good grip and response and decent rain characteristics.

Dry Grip

Compared to other tires in its class, the G-Force Sport has fairly high limits. It will never go toe-to-toe with the Kumho Ecsta MX or the Azenis RT615 in pure grip, but it easily outdoes the AVS ES100. At NHIS I found I was able to carry a few more mph into several corners after switching to the G-Force Sport.

Dry Response

Turn-in is sharp and sidewall stiffness about what I would expect from a tire of this class and size. Rollover is still a problem (particularly in switchbacks and chicanes). At 29psi cold (about 34-35 hot) I was probably getting about 1/4 of the way down the sidewall when really trying to beat on the tires; adjusting pressures up and down seemed to take the tire out of its element. The G-Force sport communicates well at the limit, squealing and getting palpably rubbery before breaking loose. Inexperienced drivers would benefit from this communication.

Wet Grip

There was no opportunity to drive this tire in heavy rain, but in moderate rain it does well. The tread has plenty of void area and deep channels. Judging by tread pattern alone, the AVS ES100 would appear to be better in the rain, but in practice the G-Force Sport bested the ES100 easily.

Complaints

Before I bought the G-Force Sports Noah warned that there were reports of chunking and uneven heating. This is indeed true. After 2 very hot track days at NHIS (80-90 degrees and much hotter on track) the tires showed some raggedness. No dangerously large chunks tore off, however. When the weather and the track temps are a bit lower, as they were when I went to Lime Rock in September, chunking was much less of an issue.

Final Reccommendation

Though the G-Force Sport is not the best tire for the money, it is a solid all-around performer that likely will not let you down. I would choose the MX, RT615, and Goodyear GS-D3 over the G-Force (and would have, had any of those tires been in stock or available in my size when I was buying). For a tire that makes no claims to be extreme, that’s not a bad group to be behind. I would certainly consider another set if I again find that those other tires are unavailable.
