Track tire wear

Generally, which will wear out faster - fronts or rears? Tires are track-only V700 Victoracers.

Lots of variables here from driving style, to HP, to chassis setup, to car weight. FWIW, victoracers on my 993 wore pretty evenly f-r, with perhaps a bit greater wear on the rears.

As Edward said, car & driver are the biggest variables.
On my 930, my F/R wears are about the same. On my buddy's 934.5, his ratio is 2 sets of rear to 1 set of fronts. Another friend's 3.2 has more wear in the rear.

Even on my low power/low weight 912 the rears get a tad more wear than the fronts, and thats both autox and high speed tracks (hummm high speed + 912 = Oxymoron)

On the track in my '87, I go through 2 sets of rear tires for every set of fronts. This is with VictoRacers (225/50 16 and 245/45 16) or RA1s (235/45 17 and 255/40 17). Car is not exactly overpowered (engine is stock except for no cat), but my driving style does involve quite a bit of throttle steering.

I'm about 2 rears for every front with A032R's.

Guys running similar cars with Pilot Sport Cups get about the same front and rear, with a little less life from the front.

Rears, no question. If your adding camber, even quicker.

On my SCCA GT-2 911, I use 2 sets of rear 12x25.5x16 Goodyear slicks to one set of front 10.5x23.5x16s.

Same here.

It depends a lot on the driver and track too.

Thanks for all the responses. I was pretty sure my rears would wear out before the fronts, and I'm convinced they will. The reason I asked has to do with longer drives to DE events. For treks up to 2 hours, I'm willing to keep 2 of the track tires on the car while 2 ride on a roof rack, and I wanted to determine which set gets to ride "al fresco". My goal is for all 4 tires to reach their wear limits at the same time, so I'll put the rears on the rack and use my streets in their place. For the really long drives, all 4 will ride up top.
