Tires: They are the one common element in all of motorsports. No matter what the powerplant, drivetrain layout, brake setup or suspension design, those four rubber contact patches are what translate it all into motion on the track. As a result, tires are one of the most rules-restricted pieces of the puzzle, and the popular 200-treadwear Extreme Performance market segment continues to evolve at a rapid pace.

When we tested the street tire class of 2015 a year ago, we found a massive leap in performance over earlier products. Not surprisingly, the two standouts in our test–the BFGoodrich g-Force Rival-S and Bridgestone Potenza RE-71R–went on to dominate the pointy end of the field throughout the year at SCCA Solo, Optima Ultimate Street Car Association, and Goodguys AutoCross events. These tires also showed so well in NASA Time Trials that for this year the rulemakers gave them the same preparation points value as many R-comps.

About the only place these tires failed to make a huge dent was low-budget endurance racing, where they simply couldn’t last long enough to be effective. What new developments will come from the class of 2016? Find out as our venerable One Lap of America Honda CRX test mule hits the track wearing some new arrivals as well as some of last year’s top tires.

245/40R15s, you say? Hmmmmmmm

I'd also be interested to see how that new Nexen N'Fera SUR4 performs.

I've been eyeballing those Vr-1's for a while, especially with the free shipping. Might be just fast enough for a good play tire.

Any word on the wear rate of the new tires?

I have the following useful lives endurance road racing:

RE71r - 8 hours

Rival S - 8 hours

Rival - 12 hours

ZII Star Spec - 14 hours

I'd imagine the Maxis is right there with the Star Spec.

Good info! If you wouldn't mind adding the following details:

What car?

The cars actual race weight?

What tire size?

Were the same alignment numbers used for all for tire models?

How many of the four tire models were used on the same tracks? (different tracks wear out tires at different rates)

Hopefully there isn't any huge shake up at the top in the AX portion of the test, I just ordered a replacement set of RE71Rs.
That being said, I've been seriously impressed at how they've held up, with bonus points for being good in the wet AND cold.
