RE-71R's Lost Grip

That might have more to do with the other drivers than your tires. Although you do seem to maintain more than a few tenths to second.

Haha, there are a lot of factors at play. I'm just making the point that one cold winter didn't turn my tires into hockey pucks

Sort of, sort of not.

AutoX has a lot of influence on the politics behind tires and how they're labeled, and is a direct reason as to why tire labeling is so misleading nowadays.

In talking to others specifically about the RE-71R, it seems to be optimal for about 1-2 years after breaking the mold release. Lots of factors in play for the in-between point until you see significant time delta to stickers.

If you see a 2015/early 2016 build date it's probably toast.

Uh, used Continental take offs are R7s

ChumpCar and other racing sanction series specing 200tw dictates that as well.

But let’s be real, tire manufacturers are not making tires solely for autox. We are the minority

Looks like mine were made in Nov 2015, so they're probably toast. Guess I'll need to find an big empty parking lot in the near future.

True, but a "normal car" also doesn't wind up on RE71Rs. These are an enthusiast tire, and a significant chunk of the sales of these specific tires are to people who are buying them for competition where treadware ratings matter. It's a well-known fact that manufacturers skew the treadware ratings to meet specific criteria.

The minority is the majority of the RE71R/Rival S 1.5 consumption. There's a reason Tire Rack sponsors SCCA Solo 2.

The 1300 cars at solo nationals this year would like to have a word with you.

Lots of those competitors only use 1 set of tires/year. And of the 1300 only about 1/2 are on street tires. The rest are Hoosiers.

If a Chump team uses RE/Rivals they're going through them at a rate of 1 set/race. Some maybe even 1 set/day. That's a few sets of tires a season for the average team. A single Chump team easily eclipses a handful of the average autocrossers.

They're more likely using RS4, though. They last longer and are better at heat management

TireRack Sponsors Solo yes, but they don't determine inventory status or dictate the 200tw game.

About 600-700 were street tired cars.

Anyways, if anyone was following the tire wars this year you'd realize that both the Rival 1.5S and RE-71Rs had significant tire shortages this year, more than prior years. This wasn't because of us consumers demanding more tires.

Tire manufactures make our molds in-between other lines of tires. I'm not as familiar with Bridgestone, but I know the RivalS are made at a facility that also makes off-road and OE manufacture tires.

You see, OE Manufacture tires are the money maker for these businesses, so they stretch the limits on how far they can produce these tires before they switch over to making another mold, same can go for Bridgestone. Luckily for BFG, they are within the US so transport is relatively easy, but Bridgestone is going across on a boat and 30-60 days out.

If we actually ever had any say in the tire game, these manufactures would keep a constant supply and inventory of tires. Unfortunately they don't and you need to horde tires to make it through a season.

Hell, I even had a hard time trying to get contingency tires this year because of inventory issues. And BFG Racing has their own stock of tires that are fulfilled first before TR and other resellers have them

The wins are the rest of us failing to drive well. Well, some of us (like me). Look at the results at the other local club we both run and its a little different. But... I'm over 160 runs on my 71's also...

Get heat in them and they improve, but never all the way as good as they can be. I've heard from sources I trust that they can cycle out as early as 80 runs. Much depends on the tire size and car.

Most scenarios to pure slicks are under-cambered street setups that eat tires for lunch... I think an STX car will likely cycle out before the wear bars. I had over 280 runs and two seasons on my last set of 255's and not to the bars yet...
